Modern lessons in natural science. Their features. Science lesson types and structure

The main signs modern lesson can be called the following Pakulov V.M., Kuznetsov V.I. Methods of teaching natural history. - M., 1990:

• 1. The lesson should be aimed at fulfilling the social order of society.
• 2. All activities of a teacher and student should be carried out taking into account the latest achievements of psychology and pedagogy.
• 3. The presence of multidimensional goals.
• 4. Statement and solution of cognitive, educational and developmental tasks.
• 5. An active approach to learning.
• 6. Changing the ratio of the functions of the teacher and students in the educational process.
• 7. Enhancement of the cognitive activity of students, the development of their initiative and creativity.
• 8. Optimization of training content.
• 9. An integrated approach to the organization of the educational process.
• 10. Perfect lesson structure.
• 11. The ratio of the rational and the emotional in the classroom.

• 18. Presence of a favorable psychological microclimate.

There are different approaches to defining the types of training sessions. Without dwelling on these approaches in detail, we will only pay attention to some of the issues that arise when considering a particular classification. So, in one of the classifications, along with others, such types of lessons as an independent work lesson, a TCO lesson (technical teaching aids), a practical work lesson are offered. In this regard, the question arises: independent work can have different goals and content and, accordingly, can be associated with the study of new material, its consolidation, its generalization and systematization, quality control of the state of educational training of students, but then whether the qualitative specificity of the given lesson is not lost type? A similar question arises about the TCO lesson and the lesson of practical work.

It seems that such a classification of training sessions is necessary, which would really reflect the educational goals and ensure the optimal construction of the learning process in connection with the study of a particular topic.

Perception -- presupposes the reflection in the human mind of the individual properties of objects and phenomena acting at this moment on the senses.

Perception involves the concentration of students' attention on a cognitive object. In perception, the subjective experience of schoolchildren is of great importance.

• - to update the subject experience of students;
• - give new material in semantic complete parts, blocks;
• - in the new material, draw the attention of students to the most important thing (highlight the main thing);
• - repeat the content of the main block.

Comprehension - presupposes an understanding by students of the studied content of the educational material.

In the process of comprehension, various connections are established between the previously studied material and the new, the reasons for the events being studied, the motives of individual actions of literary heroes, etc. are clarified.

Pedagogical tasks of the teacher:

• - to analyze the perceived with the students;
• - to highlight the algorithm - a strict logical sequence of actions in determining the essence of the studied;
• - to enable students to formulate the essential features of the new independently, taking into account the orientation towards certain content features;
• - to promote the development of students' ability to analyze, synthesize, compare, highlight the main thing in cognitive objects;
• - to reflect on the cognitive actions of schoolchildren.

Memorization - involves the preservation of knowledge in the memory of students.

It is known that one can understand this or that phenomenon, but after a while already experience difficulties in explaining it. That is why memorization is so necessary.

Reveal individual ways of memorizing information by students.

Application - presupposes the mastery by schoolchildren of the skills to apply knowledge in practice.

Pedagogical tasks of the teacher:

• - to define a system of exercises and tasks for students to apply the acquired knowledge in a variety of situations;
• - to provide a gradual increase in difficulty in performing exercises and tasks.
• - to use a variety of individual didactic flashcards to ensure the work of students with different cognitive styles.

Generalization and systematization - presupposes the reduction of the studied into a single system.

Pedagogical tasks of the teacher:

• - to connect the previously acquired knowledge with new educational material;
• - to ensure the formulation of philosophical conclusions by students;
• - use classification and systematizing schemes and tables;

The study of the logic of various types of training sessions allows us to assert that all forms of organization of training, such as a lecture, consultation, credit, etc., as well as the so-called non-traditional forms of conducting (travel, concert, literary living room, etc.), can be attributed to to one or another type of training session, depending on their educational goals (see Appendix 1 table. 1). Therefore, specifying the type of training session, it is necessary to determine the form of its conduct.

These tables allow us to talk about a wide variety of forms of organization of the educational process. At the same time, each of the named forms, depending on the subject educational goals, can be attributed to one or another type of educational lesson that we have identified. So, if a lecture is chosen as the form of conducting an educational lesson of the first type, then its logic corresponds to the logic of an educational lesson of this type. In the event that a lecture is conducted with the aim of generalizing and systematizing the knowledge of schoolchildren, its logic coincides with the logic of an educational lesson on generalization and systematization.

As a result of considering the typology of training sessions and the logic of each type, the question naturally arises: why is there no combined training lesson in this typology?

In our opinion, each of the presented types of training sessions is basically combined, since it consists of a system of stages. On the other hand, a combination of two or three types of training sessions is certainly allowed. In this situation, the correct combination of the logic of these activities from the didactic point of view is significant. Otherwise, the lesson will be just an eclectic combination of various stages of the lesson, weakly related to its goals.

The lesson as a form of organizing educational work has existed since the 17th century, that is, more than 450 years. Not surprisingly, many people think that the lesson has always existed.

What is a "good lesson"? And what is a modern science lesson in general? What are the problems and features of building science lessons in elementary school? What should be a natural science lesson in a modern adaptive school? How to make it a lesson in independence and creativity?

Currently, the school has turned to the student's personality, trying to create conditions for its formation as a subject of its own life.

Let's try to analyze the problems of the modern science lesson in elementary school.

• 1. The first problem is the formation of an elementary ecological culture, awareness of interactions in the "man - nature - society" system and the value of nature as a living condition for people.
• 2. Implementation of the principles of scientific character and ecologization, as well as the local history aspect through the regional component.
• 3. Solving the problem of the development of children in the lessons of natural science, which consists in organizing the independent cognitive activity of students in the lesson. Modeling natural objects on an activity basis.
• 4. Using the educational potential of the lesson and, in particular, the worldview - educating a person of culture, the formation of ideas and foundations of eco-culture.
• 5. The problem of the practical orientation of training (conducting experiments, practical and laboratory work, observations, experiments and excursion classes).

Let's highlight especially valuable features of natural science lessons.

• 1. Organization of educational and cognitive activities of students in the classroom, contributing to the development of the most important mental processes of thinking, attention, memory, imagination, speech.
• 2. The use of creative teaching methods (partly search, heuristic, problematic).
• 3. Building natural science lessons on an activity-based basis, using modern methods of pedagogical skills: modeling educational material, active forms of learning, personality-oriented approach.
• 4. Activation of the child's personal functions (motivation, reflection, self-determination, introspection and self-esteem).
• 5. Implementation of the principles of scientific character and greening of education.
• 6. Formation among students of a single value-colored image of the world as a home, their own and common for all people, for all living things.
• 7. Use of various sources of knowledge based on visualization (diagrams, figures, tables, models, etc.).
• 8. Pronounced developmental character, practical orientation.

At the same time, the lesson should be health-saving, developing the valeological skills of children.

Thus, the goal of natural science lessons is to educate a humane, creative, socially active person who is careful and responsible for the wealth of nature and society.

The lesson as a form of education has existed for over 300 years. He firmly entered the system of work of a mass general education school. Attempts to replace the lesson with other organizational forms are still at the experimental level. Like any pedagogical category, a lesson has its own characteristic features:

The lesson is conducted with a stable group of students of a certain age and more or less the same level of training;

The lesson is limited in time; it usually lasts from 35 to 45 minutes.

The lesson has certain functions:

Educational, solving problems of formation and development of knowledge, abilities and skills;

Educational, solving problems of patriotic, ecological, aesthetic, moral, labor, sanitary and hygienic education;

Developing, solving problems of the development of personal qualities of students, their memory, thinking, speech, worldview, ecological, ethical, aesthetic and sanitary and hygienic culture, creative abilities, skills of educational work.

At the same time, we note that such a division of the lesson functions is conditional. As a rule, they are performed in a complex manner. Indeed, it is in the process of formation and development of environmental knowledge and skills that both environmental education and the development of environmental culture take place. This complex process cannot but affect the assimilation of ethical norms, the upbringing of patriotic feelings. A worldview cannot develop without the formation of scientific knowledge. Similar examples of the relationship between different functions of the lesson can be continued.

Depending on the purpose, content of the lesson and the teaching methods chosen for it, its type is outlined. In the teaching methodology of elementary science, there is no generally accepted classification of the types of lessons. Therefore, we use our own classification (see p. 156).

Each lesson is built according to a specific structure. The structure is understood as a set of working moments, stages, their order, due to an internal logical connection. In the structure of the lesson, the following stages are usually distinguished:

1) organization of the beginning of the lesson;

2) repetition and consolidation of what was learned in the previous lesson, and sometimes several previous lessons;

3) study of new material;

4) consolidation of new material;

5) generalization and conclusion on the studied material in the lesson;

6) homework.

This structure is inherent in the lessons of elementary science. However, it varies depending on the type of lesson, its specific content and the methodology used.

Let us dwell on the characteristics of each type of lessons in elementary science.

Introductory lesson. Typically, such a lesson is held at the beginning of the school year as an introduction to the subject, and at the beginning of the topic as an introduction to the topic. Due to the fact that the number of hours allotted to primary natural science is small, it is possible to single out only lessons that are introductory to the subject. As a rule, a short time is allotted for an introduction to a topic in the first lesson on the topic. Therefore, in the practice of studying natural science in elementary school, only four such lessons are conducted.

The structure of the introductory lesson has its own characteristics: there is no repetition of the knowledge of the previous lesson. The lesson begins with clarifying the children's understanding of the essence of the name of the academic subject. If last year the children have already studied such a subject, and this year it is being continued, it should be remembered in general terms what is the main object of study for this subject, what students already know about this object, what was interesting.

Further, the teacher informs that acquaintance with nature continues in this academic year; names the questions to be covered, textbooks and teaching aids to learn. Observations in nature, hands-on work, and classroom experiences will help you gain good knowledge. Children fluently leaf through books, express their initial impressions of them. Usually, textbooks are opened first, then textbooks, one reads successive references to them and, under the guidance of a teacher, discusses their essence. Then the teacher explains how to navigate the textbook; analyzes the content (table of contents) in the conversation. After reading it, the children are convinced that the table of contents shows what they will learn during the year. Students find the topics and subtopics named in the table of contents through the pages indicated in the table of contents. If signals-symbols are used in the textbook, their essence is analyzed and verified in the conversation by comparing the image of the signal and the activity that is laid down in the corresponding structural component of the book.

Quite often the text "Introduction" is placed in the textbook. It can be worked out in the lesson using the apparatus for organizing assimilation given to it.

As a homework assignment, you may be asked to make observations on the topic of the next lesson.

Mixed or combined lesson. This type of lesson differs in that it almost always contains all the named structural components of the lesson. It is carried out in a variety of methods and techniques. Within the lesson, a variety of organization of student activities can be applied. Here is a brief description of each structural component of this type of lesson.

The lesson usually begins with an organizational moment, which has as its purpose to establish a working mood in the classroom, to mobilize the attention of students to the work ahead. This part of the lesson is given a minimum time, no more than one minute.

Repetition and verification of what was learned in the previous one, as well as repetition of the previously learned lesson takes 8-10 minutes, but in exceptional cases the duration of this stage can last 15 minutes. Shouldn't take more time for this view

work. Due to the fact that the repetition technique, its functional significance is more or less the same for all types of lessons, this material is taken out in an independent paragraph.

Learning new material is the most important part of the lesson, so it usually takes up to 25 minutes. Each teacher strives to make the study of new material in the lesson most effective. This can be achieved using a variety of methods and techniques. This stage of the lesson begins with an introductory conversation, which allows the child to revive his existing knowledge on this topic and thereby connect the new knowledge with the existing one. It also reproduces the content of the observations carried out after school hours. Thus, the teacher receives feedback on what the children know, what is the preliminary degree of understanding of the material to be studied, whether the children's knowledge needs to be corrected. The further course of studying new material depends on such a conversation. If the new material is closely related to the previous one, if a sufficiently large volume of observations is made after school hours and the latter are quite rich, the formation of new knowledge can be limited to conversation. But, as a rule, this method alone in the lesson is not enough, therefore, we present possible options for the methodology for learning new knowledge.

The teacher can convey some of the new information to the class using the storytelling method, taking into account the requirements for it, its positive and negative sides (see p. 122). Children can gain some knowledge by reading the text or part of the text of the textbook. At the same time, it is necessary to take into account the peculiarities of the content of natural science textbooks and the tasks of teaching natural science in elementary school. First of all, in most of the variable textbooks, the texts are popular science, not fiction. Primary natural science does not set the development of reading techniques as its leading task. It should give certain knowledge about nature. This also leaves an imprint on the method of working with text in a natural science lesson. Before reading a text or part of it, both in reading lessons and in science lessons, children must be assigned certain tasks. In a reading lesson, they have approximately the following wording: "learn to read the text well," "learn to read expressively," etc. This type of assignment is not typical of natural science lessons. Based on the tasks of this academic subject, before reading the text, mainly cognitive tasks are given. Therefore, they have different wording here. For example: “Read such and such a part of the text and answer the question how to protect birds in autumn”, “Find out from such and such a text of the textbook how a person adapts to the nature of the tundra zone”, etc.

At the stage of learning new material, there may be presentations of students with short messages (there may be one or two) on the topic of the lesson. As a rule, messages are prepared in advance. On the one hand, they should correspond to the topic of the lesson, on the other, their content may be somewhat broader than the information given in the textbook. Otherwise, the messages lose their novelty for the class, and interest in them disappears. Do not force message topics on children. You can offer the class several of them, and then, in individual work with the child, the wording of the topic can be clarified taking into account the wishes of the student himself. So, the subject of the message has been formulated. Now the teacher can give the student some advice: name some books, but not as obligatory, but only as possible, so that the student himself selects any sources of information; discuss with the child what personal observations can be included in the message, how it can be illustrated; it should be advised that personal value judgments, a personal attitude to the subject, the phenomenon referred to in the message are expressed in the message; invite the child, if necessary, to seek advice; it is also useful to listen in advance what and how the student will tell in the lesson.

In the above examples of learning new material, verbal methods play a leading role. Their use should be combined to the necessary extent with the use of different types of visual aids.

The child can receive part of the new knowledge in the course of independent work with various visual aids, when they provide the activity of visual methods. In this case, the visual aid is the main source of knowledge. But in order for it to fulfill this function, the teacher gives the class instructions in the form of questions and tasks that direct the child's activities to the study of this visual aid.

When studying new material, practical and laboratory work can be carried out. For their implementation, mainly practical methods are used: determination and recognition of signs, observation, experiment, modeling. The structure and methodology of practical and laboratory work is the same as in the subject lesson. Therefore, we will not dwell on this here.

When studying new material, games can be used, works of oral folk art, excerpts from additional, in particular fiction, can be used. The content of a literary work or its excerpt should correspond to the content of the lesson, its emotional mood. It should not be taken as an insert into the general outline of the lesson that

11 Aquileva. Methodology

often takes place in practice. A work of fiction can lay the foundation for the study of some kind of educational material. It can be used as a generalization. It can enhance emotional experiences from what is observed by the child himself, etc. For example, when discussing observations of autumn changes in plant life, children will note that the leaves of deciduous plants change color. They turn yellow, red, brown. This makes the autumn forest beautiful. Now the teacher can tell the children that the poet I. Bunin also saw the autumn forest. It is possible that this was the same forest that we saw. Now listen to how the poet said about what he observed. The teacher reads the well-known poem by I. Bunin "The forest is like a painted tower ...". The first quatrain is enough. Children compare the same vision of the forest and different expressions of admiration for the forest. This stimulates repeated observations of children: someone will certainly want to see the colors of the forest, but now not yellow, red, brown, but gold, purple, crimson; not just a beautiful forest, but a "painted tower". Such a comparison enriches the child's speech with epithets, contributes to a deeper understanding of the work of art. Thus, the teacher involuntarily decides intersubject connections. With the help of literary works, you can create problem situations. For example, when studying plants and animals of different landscapes, it is difficult to avoid listing these objects. However, just listing makes learning new material boring and edifying. The teacher here can apply the following technique: you will name the next plant (animal) yourself if you guess the riddle. Next, the teacher makes a riddle.

The study of new material ends with its consolidation. Functionally, this stage of the lesson is very important. Its very name already defines one of its most important functions - consolidation. In addition, consolidation systematizes what was learned in the lesson and leads to generalization. 3-5 minutes of the lesson are allotted for consolidation. The forms and methods of consolidation are the same as when studying new material. However, they are used to a much lesser extent. It is not out of place to observe one more rule: it is desirable to apply those forms and methods that were not used in this particular lesson when learning new things.

Consolidation ends with a generalization of what was learned and a conclusion from the lesson. This is "a very important part of the lesson, because it allows you to systematize knowledge, to highlight general provisions, which most often form the basis of the student's knowledge fund. Consolidation improves the most important skill of educational work - the ability to highlight the main, essential, common from a large number

information. Therefore, we do not share the opinion of those teachers who consider this stage of the lesson to be superfluous.

Homework may not be given in every lesson, but it is usually necessary in mixed lessons. The meaning and method of homework are common to all types of lessons.

Here is an example of a methodology for conducting a mixed lesson in the fourth grade 1.

Lesson topic- "Variety of surface shapes." It is advisable to prepare illustrative material for the lesson about various surface forms: flat and hilly plains, hills, ravines, low and high mountains. Repetition is carried out by the method of conversation, the basis of which can be formed by the questions used to consolidate knowledge in the previous lesson.

Learning new material can begin with an introductory conversation that uses the preliminary, anticipatory observations of the children. We believe that the students' answers will be very rough and inaccurate. Therefore, further work can be carried out as follows. The teacher first demonstrates illustrations of a flat plain. The class is invited to consider and characterize the depicted surface, which can be called flat. On the basis of this statement, the concept of "plain" is introduced. Then the children, using illustrative material, compare flat and hilly plains, find similarities and differences in them, give a comparative description of both types of plains, and substantiate their names. Hilly plains are characterized by hills. As it were, ravines serve as the surface shape opposite to the hills. The students have already familiarized themselves with the ravines, so now it is necessary to invite them to tell themselves what this surface shape is; decide on which plains can be ravines; make an appropriate entry in task 37 of the workbook.

Plains look different in different places. How exactly? Students can learn about this either from the text of the textbook or from the teacher's story. It is desirable to illustrate the content of the text or story. The teacher then introduces the class to the pictures of the plains on the map. Students find plains on the map of Russia. In this case, it is not necessary to demand that you remember their names.

Similarly, with the help of illustrative material, children get acquainted with low and high mountains, with their features; they learn that there are valleys and gorges in the mountains, they find similarities and differences in them. The teacher helps to highlight the sole of the mountain, the top, the slopes.

Now the class can be given the task of making drawings of the studied surface shapes in notebooks.

The mountains are very diverse. Students can learn about exactly how the mountains look from the text of the textbook or the teacher's story. As in the study of the plains, it is advisable to show illustrations of different mountains, not limited to textbook drawings, and draw drawings in a notebook. The teacher then introduces the students to the depictions of high and low mountains on the map. Children find these surface forms on the map of Russia, determine by conventional signs (by color intensity) which mountains are high and which are low.

To consolidate the educational material, the class can be asked to determine the shape of the surface from their descriptions. For example, the following description of a flat plain can be offered: “A flat surface, like a table, spreads over vast expanses. Whether you are driving along it, or flying over it, nothing breaks the monotony. "

In conclusion, a conclusion is drawn from the lesson. He might be next. “Plains and mountains are forms of the earth's surface. Depending on which surface forms prevail on the terrain, the surface is flat or mountainous. On the plains there are hills and ravines, and in the mountains there are valleys and gorges. "

Homework. Know what surface shapes are, what each of them looks like, how different surface shapes are depicted on the map. Be able to find and show them on the map. This assignment can be supplemented by completing assignments in the workbook.

Object lesson. In the methodological literature, this type of lesson has other names: a lesson in working with handouts, a lesson with practical work. The essence of such a lesson lies in the fact that the object for study is transferred into the hands of the student, and the leading forms of children's activity are practical and laboratory work. The latter can be organized as frontal or group, or individual. The role of this type of lessons in the educational process is very great. They allow you to accumulate a certain stock of specific ideas about objects and natural phenomena, which, as already indicated above, is the basis for the formation and development of concepts, judgments, and inferences. These lessons develop important practical skills and abilities. Such are, for example, the ability to work with instruments, laboratory equipment, etc. The senses are improved, observation, perseverance, the ability to overcome difficulties and bring things to the end, etc. are developed.

The structure of the subject lesson is somewhat different from the structure of the mixed lesson. Younger students still have weak skills

practical work, it takes a lot of time to complete the latter. Therefore, there may be no repetition in these lessons. If the teacher nevertheless plans this stage in the subject lesson, his methodology is the same as in the mixed lesson. Most of the time (25-28 minutes) is devoted to the study of new material. A prominent place here is occupied by the consolidation and generalization of educational material - 7-10 minutes of a lesson. The rest of the time is allocated between organizing the class for the lesson and homework.

In the course of studying new material, several stages can be traced.

1. Students receive an object of study or several of them at once. Ideal when objects are in the hands of each student. In this case, work can be organized both frontally at the teacher's signal, and individually, when each child works independently. But in practice, such opportunities are very rare due to the lack of the required amount of handouts. Therefore, children can be grouped together. In this case, two options for organizing the work of groups are possible. If the groups receive the same study objects, the work can be carried out by each group both frontally and independently. If groups receive different objects, their study can be carried out in the overwhelming majority of cases by groups of students on their own. But at the same time, as the study of objects, they are passed from group to group. This option allows you to conduct a subject lesson in the presence of a small number of objects, each of which can even be in one copy. For example, a teacher needs to conduct a subject lesson to study the characteristics of steppe plants. There are only four herbarium leaves of different plants in this natural area. Students are divided into four groups, each of which receives one herbarium sheet. As you explore, the groups change plants.

2. Instructions for practical (laboratory) work can be given to the class in the form of oral assignments, written on the board, on cards. As an instruction, tasks of a textbook for practical work can be used. Depending on the provision of the class with objects for study (see above), the instruction may contain either the same tasks for all students, or different. In the latter case, tasks between groups change in accordance with the change of objects of study. Assignments can be given to the class one at a time, or they can be grouped or offered all at the same time. If necessary, the teacher explains the tasks, shows practical techniques for their implementation.

3. Students' independent work on the study of the received objects in accordance with the tasks received should not be ignored by the teacher. It requires some control (but not a substitution of children's activities). It is necessary to make sure that the children really work, and not be distracted, pay attention to how correctly they use the devices, because during a one-time demonstration, students cannot always accurately learn the method of work; sometimes it is necessary to re-explain the essence of the assignment to all or individual students, etc. As a result of completing independent work, students come to their own conclusions.

4. Discussion of the conclusions reached by the children in the course of independent work, with the goal of identifying the main content of the knowledge that is planned to be formed in the course of this work. Sometimes in the course of it, children come to the wrong conclusions. In this case, it is undesirable on the part of the teacher to reject the wrong knowledge and communicate the right one. This way of forming children's knowledge is the easiest, but least effective. The knowledge transferred in this way is very quickly forgotten by students. Therefore, it is necessary to organize additional research work by using logical methods. For example, in the subject lesson "Snow and Ice", while figuring out the color of ice, children often come to the conclusion that the ice is white (blue, gray, etc.). If, during the discussion, the teacher immediately rejects the children's opinion as incorrect and reports that the ice is colorless, such knowledge, not acquired by the child, is formally and very quickly forgotten. In this particular case, additional research is organized as follows. The teacher prepares white, gray, blue subjects in advance. Suppose the children called the ice white. Without rejecting the children's opinion, the teacher shows the class a white object and asks to determine its color. Students do this without difficulty. Ice is now displayed next to a white item. The teacher asks: "Is the ice the same color?" This is how the children make sure that the ice is not white. In the same way, the opinion that the ice is of some other color is rejected. A problematic search situation is created. The reasoning goes something like this: "Since none of the colors are suitable for ice, it means that it is colorless." In this case, the logical method of opposition was applied.

In some cases, the knowledge of students can be supplemented by the teacher with information that cannot be obtained in the course of practical work, but which are important for the characteristics of the object or phenomenon under study. For example, in the subject lesson Houseplants, the teacher explains why houseplants are evergreen and why they are kept in warm rooms in winter.

Studying early flowering plants in the course of practical work, children find that the underground parts of such plants are thickened. It is clear that students will not be able to establish the physiological essence of these thickenings. It is impossible to organize additional research in primary school. Therefore, the teacher explains that in these thickened parts there are reserves of nutrients, which are used by the plant during early flowering.

Consolidation of educational material is carried out by the same methods and techniques as in a mixed lesson. As in a mixed lesson, a conclusion is necessarily drawn in a subject lesson.

In their homework, along with the task to consolidate the content of the lesson's knowledge, students may be asked to conduct similar observations and experiments at home or in nature (with adults).

As you can see, the leading methods of conducting subject lessons are a group of practical methods. These lessons cannot be conducted without the use of verbal methods, from which conversation and explanation are applied.

Here is an example of a methodology for conducting a subject lesson in the third grade.

Lesson topic- "Thermometer. Temperature measurement ". Handouts should be prepared for the lesson: thermometer model; room, outdoor and water thermometers; glasses with warm and cold water; the teacher has a medical thermometer; if possible, pieces of ice in a bowl.

Due to the fact that there is a rather laborious practical work for students, the repetition of the material from the previous lesson can be omitted.

Learning new material begins with a conversation on weather observations: what kind of weather did we observe? How is the weather distinguished by cloudiness? How is weather distinguished by precipitation? What types of precipitation have we observed? How do people dress according to the weather? What kind of weather is it related to? (It is either warm, or hot, or cold, etc.) The content of the last answers allows the teacher to make the transition to the new material.

Indeed, the weather often interests us in order to decide how to dress when going outside. When they say "warm", "hot", "cold", they mean the air temperature. It is inconvenient to characterize the temperature with these words. In addition, different people experience temperature differently. Practical work will help to verify this. Three glasses are distributed to the students' tables, in each of which cold, warm and hot water is poured in succession. The temperature of the latter should be about 60 ° C. Children simultaneously dip their fingers into cold and hot water. After about

for one minute, the teacher suggests moving both fingers into warm water and observing your feelings. Children find that water feels warm to one finger and cold to the other. Based on this research, students are convinced that it is uncomfortable to measure the temperature of water, and therefore of air. Therefore, scientists have created a special device - a thermometer. The words "temperature" and "thermometer" should be written on the board. Then, in the course of practical work with real thermometers (but not medical), students figure out the thermometer device by highlighting a scale in it, a transparent tube with a small reservoir at its bottom, filled with a colored liquid. Some thermometers have these working parts in a transparent case. Further practical work continues on the following tasks.

1. Consider other thermometers. Pay attention to their shape. Find a scale and a tube of colored liquid on them. Find out if the working parts of the thermometer are in the case. If there is a case, then what is it. Think about why he is like that. 2. Compare different thermometers. What do they have in common? How do they differ? How are each applied? Try to explain why thermometers have different shapes. 3. Consider the liquid in the tubes of different thermometers. What color is it? Why should the liquid be colored? In the course of this work, children must learn the names of different thermometers. The titles can be read in the textbook or told by the teacher. The class is now asked to explain these names. In the course of this work, students also become familiar with a medical thermometer. However, this device should not be given into the hands of children, and class students get acquainted with its structure and purpose during the demonstration of this thermometer by the teacher.

The results of this practical work are consolidated by completing the following task in a notebook: in the figure depicting a thermometer, students sign the names of its parts. If there is no such drawing in the workbook, then the children can complete it themselves. You can only write down the names of the parts of the thermometer.

Then the teacher draws attention to the thermometer scale, consisting of divisions, introduces the concept of "degree", shows the border between degrees of heat and degrees of cold, teaches you to read and write down different temperature indicators correctly, explains why it is necessary to write the Latin letter "C" near the temperature indicator in degrees ", Which means" Celsius ". Children work with thermometers at the same time. Then they perform several exercises: on the thermometer model they put aside the ones given by the teacher.

readings of positive and negative temperatures, record these readings in numbers in a notebook (+ 5 °, -5 ° С).

“So,” says the teacher, “on the model, we move the strip ourselves. How does a real thermometer work? "

You can acquaint children with the work of a thermometer in the following practical work. Two glasses of water should be placed on the students' tables. In one of them the water is cold, in the other it is warm. Students, on the instructions of the teacher, first lower the thermometer into cold water and observe that the column of liquid in the thermometer's tube began to descend. Then they put the thermometer in warm water and find that the liquid column is now rising. From this study, it is concluded that the higher the liquid column in the thermometer tube, the higher the water temperature and vice versa. Now this conclusion is transferred to the state of air and the identical operation of the thermometer in it. If the textbook contains such information, then our conclusion can be checked against the textbook.

Next, you should familiarize yourself with the rules for using the thermometer. If the textbook does not contain these rules, it is advisable to prepare an appropriate poster before the lesson. Students can read the rules. As you read, each rule is explained in a brainstorming discussion and, if necessary, tested in practical actions. So, you should understand why a street thermometer should be placed on the side of the window that is least heated by the sun. To find out the rule about what level the observer's eye should be at when reading the temperature, they again carry out a little practical work: children take thermometer readings in different positions of the end of the colored liquid in relation to the eye: below eye level, above this level and exactly at eye level ... In this study, students are convinced of how to look at a thermometer correctly and why they should look that way. In a practical way, it is necessary to check the action of the following rule: a column of liquid in a tube of a water thermometer, taken out of water, immediately falls. This means that the temperature by a water thermometer should be measured without removing the thermometer from the water.

Particular attention should be paid to the rules for handling a medical thermometer. Children should learn that its tube is filled with a poisonous liquid metal - mercury. If such a thermometer accidentally breaks, mercury will spill out. Once in the air, it evaporates and can enter the human body when breathing. This leads to serious illness and often death. Let the children decide for themselves how to handle a medical thermometer, whether it is possible to play with it, throw it, etc.

Consolidation of knowledge can be carried out during the conversation, for example, on the following questions: what are the thermometers. Where are the different thermometers used? What is the construction of a thermometer? Show the parts of the thermometer on the room thermometer. What rules must be followed when working with thermometers? When answering the last question, it is necessary to ensure that, having formulated the rule, the child explains it. Another option for fixing is possible: working with the drawings of the textbook, completing tasks in the workbook, the game "Weather Bureau", etc.

The lesson concludes with a conclusion. It can be something like this: “A thermometer is a device for determining the temperature of water, air, and the body of a person. Determine the temperature on the scale and level of the liquid in the thermometer tube. It is necessary to follow the rules for working with a thermometer. "

Homework. Prepare material about the thermometer. To do this, you need to read the text, consider the pictures on such and such a page of the textbook. Review some practice activities (the teacher can specify which ones). For extracurricular observations, tasks can be given depending on the topic of the next lesson and the changes taking place at a given time in nature.

At the end of the lesson, after or before recording the homework, the teacher informs that from today on, the air temperature will be monitored by a thermometer. The temperature must be recorded in degrees in the calendar of nature and labor, and on certain days in the workbook. During recess, everyone will look at a street thermometer, take its readings and write down the date and thermometer readings in a workbook. Those responsible for keeping the calendar of nature and labor record these readings in the calendar. If a school outdoor thermometer is not available for observation by all students, one person takes a reading of the thermometer. All students in the class record temperature data under dictation. This recording can be done at home as well.

Excursion lesson. In the methodology of natural history there is no established opinion about what an excursion is. Some authors consider the excursion a method. Others, although they consider the excursion to be an organizational form, consider it a special form.

We do not share the opinion that excursion is a method. Indeed, the source of knowledge during an excursion is not the excursion itself, but observations that children perform in nature, in a museum, in a reserve, etc. To distinguish method from form, it is necessary to establish what is the source of knowledge. We do not consider an excursion to be a special form of organizing student activities. Here we are talking about compulsory study tours defined

program aimed at its implementation. Such an excursion has all the signs of a lesson, which it is worth recalling here: it is conducted with a stable group of students of approximately the same age and the same training, has a certain duration, the same as all other lessons in this class and in this school, it must perform the same functions as other lessons (see pp. 155-156). In addition, the excursion arose in the middle of the 19th century and was viewed precisely as a lesson. Based on all that has been said, we consider the educational program excursion as one of the types of lesson, and therefore, when characterizing it, we will rely on the general structure of the lesson.

On an excursion, as in a subject lesson, students deal directly with the subject of study. However, in a subject lesson, the object of study is completely or partially isolated from the natural environment. On excursions, objects are studied in a natural setting or close to it. The latter is typical for museums, some exhibitions, etc. The content of the excursion should include only what the children can directly study at the place of its holding. You should not waste your excursion time on stories that children cannot directly perceive on excursions. The only exceptions are cases when it is necessary to establish the fact of the absence of the desired object. For example, on a winter excursion to nature, the task is to find insects. Students will not see adult insects, but may find them in the pupal stage. This observation is reflected in the conclusion accordingly. There are times when a teacher takes various visual aids on an excursion and replaces direct observation with the work of students with these aids. This type of work cannot be called an excursion. However, there are cases when the teacher needs to take some objects for study with him. For example, on a winter nature excursion, students study the condition of conifers at this time of year. Children see cones in the trees. But you cannot pluck them from the tree for reasons of environmental protection and the protection of children's health. Knowing this situation, and it is clarified in the process of preparing for the excursion, the teacher takes a certain number of cones with him and distributes them to the students for study. Another example. On a winter excursion, it is necessary to establish that some insects hibernate under the bark of trees and bushes. If there is no dead tree or stump at the site of the excursion, from which pieces of bark can be removed and examined without harm to nature, the teacher also takes them with him.

Excursions differ in the peculiarities of the organization of the cognitive activity of students: they can be either illustrative

ny or research. A combination of both of these types is possible.

Each excursion must be prepared in a certain way. First of all, you should determine and study the place of the excursion. If an excursion is carried out in nature, then the day before you need to visit the excursion site, outline objects for study, directions for the movement of excursionists, determine the possibilities of excursion fees, think over and then prepare the equipment that is necessary for working on the excursion. On the site of the excursion, you should very carefully study the possibilities of collecting in nature and think over the equipment accordingly. Without prejudice to nature, you can collect fallen leaves, cones of conifers, some of the fallen fruits, pieces of the bark of a dead tree, dig up weeds for the next lesson and for herbarization, collect insect pests (for example, Colorado beetles, cabbage butterfly caterpillars), parts of plants damaged by them etc. If an excursion is conducted to a museum, reserve or somewhere else, it is also necessary to visit these organizations in advance in order to determine which expositions are more interesting for children and they should be studied on excursions, agree with a guide or get permission to lead the excursion yourself, find out the possibilities of fees. If the excursion will be led by a guide, it is necessary to agree with him its duration, content, based on educational goals, some features of the excursion, taking into account the age characteristics of younger students. On the eve, children should be warned that an excursion will take place then and there, advise them how to dress. Part of the equipment necessary for the excursion can be prepared by the students themselves, which the teacher determines in each case.

The next stage is the excursion itself. It begins with an introductory conversation, in which the topic of the excursion, its purpose is reported, it is briefly found out what the students know about this topic. The latter is important, since it allows you to establish a connection between new knowledge and those already known to children, to establish the scientific accuracy of this knowledge. If the excursion is planned as illustrative, then the teacher or guide leads the children from object to object and, using the storytelling method, conveys the necessary information to the students. During the excursion, children, on the instructions of the guide or on their own initiative, can take notes. At the end of the tour, a conclusion is made. The positive side of such an excursion is that during the excursion, students receive a fairly large amount of new information, get acquainted with a large number of objects. However, when preparing such an excursion, the guide must select the necessary

there is a large amount of material, the educational effectiveness of such an excursion is not great. Children's activities here are purely reproductive. The knowledge gained in this way is quickly forgotten. Often, by the next lesson, children cannot remember the necessary details of the objects studied during the excursion. Conducting such excursions does not present any particular methodological difficulty.

Let us consider in more detail the method of conducting a research excursion. For such an excursion, the teacher develops assignments for research. He writes them down in advance on cards or asks the children orally during the excursion. The excursion can be carried out frontally, that is, according to the instructions and signal of the teacher, all children conduct the same research for a period of time set by the teacher. But students can be divided into groups. In this case, groups can receive the same tasks for studying the same objects or the same tasks for different objects. For example, these groups are offered different plants for study, but the research plan for the latter is the same. In addition, groups can study different objects for different tasks. They also use the option of conducting a research excursion without dividing the students into groups, when all children perform the same tasks. A mixed version is also possible.

The course of a research excursion is in many ways similar to the course of a subject lesson and can be presented in the following diagram.

1. An object or objects for observation are indicated to students or groups of children.

2. Tasks are brought to the attention of the tourists, according to which the study of objects will go. They are distributed among students depending on the planned organization of their activities. In the practice of conducting excursions, the first and second stages are carried out in close interconnection, often at the same time. Assignments should be formulated very clearly, without wasting words. They should determine the sequence of studying objects, and, if necessary, pay attention to some of their details. Comparison tasks are useful, which will help to more clearly detect, and, therefore, characterize the qualities, manifestations and individual aspects of the object under study.

3. Independent work of students to study the object. At this stage, the observation method is the leading one. As in the subject lesson, this activity of children should not be ignored by the teacher. It may be necessary to provide additional clarifications on assignments to all or individual students, to replace objects of research, to provide assistance in collecting, etc.

4. Discussion of the results of independent work. It can proceed in different ways. If the excursion is conducted as a frontal one, then the discussion of the results of independent work is carried out after the completed each task. If students perform several of the same tasks at once and are organized into groups, then individual students can speak from the groups in a brainstorming discussion. In this case, general knowledge is formed on the basis of the observed objects. If the groups had different assignments and on different objects, each group brings their research to the attention of the other groups. At the same time, it is very important that children not only talk about the results of independent work, but also confirm them by demonstrating the observed objects, create opportunities for other groups to perform some observations fragmentarily.

There are times when children in the course of independent work come to the wrong conclusions. For example, on excursions, children are invited to study trees, shrubs, grasses and establish their distinctive features. As a rule, younger schoolchildren do not pay attention to the number and nature of stems in plants of these groups. Insignificant signs are distinguished: the trees are large, the shrubs are smaller, and the herbaceous plants are even smaller. As in the subject lesson, you should not reject such an opinion of the children and immediately enter the correct information. The class is encouraged to do more research. Therefore, when preparing for the excursion, it is useful for the teacher to choose a place where the grasses are high, for example, nettles, burdock, shrubs are low, and the trees are small. The last can be young trees (the first year of life), in growth below shrubs and even some tall grasses. The teacher shows these objects, suggests showing where there are trees among the plants, where are bushes, and where are herbs. As a rule, children identify them unmistakably. Now the guys have to check themselves on these objects: whether they correctly put forward the signs of distinguishing between trees, shrubs, grasses. Students become convinced of the wrong conclusions. A problem arises that the children want to solve. Now the teacher proposes to count the number of stems in representatives of these groups of plants, to examine them for hardness. As a result, the correct conclusion is formulated: trees have one ligneous stem (trunk), shrubs have several ligneous stems, grasses may have one or several herbaceous stems. They are soft, juicy.

5. Generalization and formulation of the conclusion.

If fees are provided for the excursion, then they can be performed at the end of the excursion or during its course, as the tasks are completed.

There may not be any homework after the excursion. But the class can be asked to complete the corresponding tasks in workbooks, to conduct similar observations in another place, to supplement the observations on the excursion with other observations of objects that were not at the site of the excursion.

If the excursion has been collected, then after the excursion it is necessary to put them in order. For example, if the plants are collected for a herbarium, then they must be put into herbarium folders for drying. Brought with excursion tree branches must be placed in the water. The children put cones, fruits of plants, pieces of bark in boxes. If children want to observe the development of the cabbage caterpillar (cabbage), then it must be placed in a light plastic jar directly with the cabbage leaf, then the cabbage leaves should be periodically placed. The question of handling excursion fees is decided by the teacher on a case-by-case basis with regard to the content of the excursion, the possibilities of performing the fees and the possibilities of the room where the fees will be stored.

So, on excursions, the main source of information is the observation method. The experiment can be applied. From verbal methods on illustrative excursions, story is used, on research - explanation and conversation.

Here is an example of a methodology for conducting an excursion in the fourth grade.

Lesson topic- “Features of the reservoir. Plants and animals inmilking. The influence of human activities on the reservoir. "(Excursion). On the excursion, you need to take a landing net, a compass and transparent dishes, such as cut plastic bottles. In the upper part of the containers obtained in this way, on opposite sides, they make a hole through which the strings are threaded. This is how a handle is obtained, which creates certain convenience when carrying and using cans.

At the site of the excursion, it is established what kind of reservoir it is (river, stream, lake, pond or other). Children determine by compass in which direction this body of water is from the settlement; what are its banks (steep, gentle, overgrown with forest, bushes or grass); where is the right, and where is the left bank, what is the direction of the water flow (for a river, stream), what is the quality of the water in the reservoir (clean, transparent or turbid). Based on the results of these observations, students make a brief description of the reservoir, note what its beauty is, whether it itself gives the beauty of the surrounding area.

a lot of algae. But many flowering plants also live here. Therefore, in order to avoid mistakes, it is necessary to use the term "aquatic plants", that is, those adapted to life in a reservoir.

In the coastal part you can find sedge, reeds, cattails. These plants are flowering, not algae! It should be noted that the lower part of such plants is in the water. It is necessary to warn the children not to touch the sedge, since its leaves can hurt. From a convenient place, it is advisable to look into the water and see various algae, elodea. This means that some of the plants in the reservoir are completely submerged in water. Tourists will see duckweed on the surface of the water. It can be viewed only on the water, as taken out of the reservoir, it turns into a solid green lump. Shiny flat leaves of water lilies or egg capsules float on the surface of the water. The students conclude that there are plants in bodies of water that live on the surface of the water. In the lesson that follows the excursion, these groups will be specified.

Children, without harm to the reservoir, can collect duckweed, catch an elodea or a water pine with a net. When these plants are taken out of the water, it is necessary to compare their appearance in air and in water: the removed plants have lost their shape, beauty, and it is difficult to recognize them. The collected plants are placed in jars of water. Then the students study in detail one aquatic plant, make up its characteristics according to the same plan that was indicated in the topic about meadow plants. Based on these observations, a collective discussion of the characteristics of aquatic plants is carried out. Duckweed, elodea, water lily, egg capsule are flowering plants.

The students then observe the animals. Among the coastal plants you can see insects, such as dragonflies, on the shore - frogs, on the water - waterfowl and insects, such as swimming beetles, in the water - fry of fish and molluscs, such as pond snails and snails. Students should be encouraged to scoop up jars of water and look at the light. Children will see many small moving creatures. These are crustaceans. Tourists should be given the opportunity to choose an animal and make its characteristics. The teacher should take into account that in a collective discussion, descriptions of animals in children will be much less complete, clear and systematic. Only fragmentary

intelligence.

Next, you need to draw the attention of children to the activities of people. It is observed either directly or indirectly. Students are encouraged to explain why people use this reservoir this way. Some evidence of environmental protection measures is possible.

At the end of the excursion, a conclusion is made about what the investigated reservoir is.

Homework. Know what the observed reservoir is (size, name, location), what plants and animals inhabit it; be able to explain how and why that is how people use it. Record the results of excursion observations in a workbook.

The jars with plants brought from the excursion must be placed in a dimly lit place. There is no need to put cans with small animals in a bright place. Otherwise, in the light in the banks, algae will develop very quickly, which will greatly worsen the breathing conditions of aquatic animals. As a result, the latter may simply die, and if the animals do not die, then it will be very difficult to consider them in the next lesson in the green mass of algae.

Generalizing lesson usually builds on the material of a particular topic or subject as a whole. The most common mistake in conducting such a lesson is to reduce the entire work to a sequential repetition of the factual material of the topic without any generalizations.

The most important task of generalizing lessons is to reveal the essence of natural science concepts, to establish relationships between objects and natural phenomena, and on their basis - the initial acquaintance with some laws. In generalizing lessons, the exclusive role belongs to the method of conversation, which should alternate with work on visual aids using a textbook, workbooks and other aids.

The peculiarity of generalizing lessons is determined by their structure. For example, we will give a diagram of such a lesson.

1. Organization of the class for work, communication of the topic and the purpose of the lesson.

2. Conversation on the material of the studied section. Based on the general objectives of the generalizing lessons, a variety of questions should be included in the conversation. The first group of questions is aimed at reproducing certain factual material. These are questions with the words "who?", "What?", "What?", "What is it?" etc. It is not at all necessary to reproduce all the factual material of the topic. It is important to select what is essential in formulating conclusions for a section.

The second group of questions should help children to identify the essential signs and properties of objects and phenomena, to establish and realize some objective relationships between them. The formulation of such questions is based on the use of logical methods (see pp. 142-146).

The third group of questions allows us to highlight the common features of the studied objects and to formulate concepts. These are questions with the word

12 Aquileva. Methodology

phrases “what is common in them?”, “what unites them?”, “how can they be called in one word, one phrase?”. The allocation of common features is facilitated by the use of classification.

3. The conversation ends with a general conclusion, in which, from the initial generalizations already made, their general features and peculiarities are reflected.

At the end of the lesson, the teacher makes a conclusion, noting what material and to what extent has been learned by all students in the class, individual students.

The question of homework is decided depending on the quality of assimilation of the material in the section and the conclusion made by the teacher. If the teaching material is mastered with sufficient quality by all students in the class, there may not be homework on the topic covered. The assignment can be obtained by individual students and on individual questions of the section.

Here is an example of a methodology for conducting a generalizing lesson in the third grade.

Lesson topic- "Summer and autumn in nature"(generalizing on the topic). It is advisable to conduct the lesson during the period of the actual end of autumn in nature, which is determined approximately by the following signs: the transition of the average daily temperature below 0 ° С, the establishment of permanent snow cover, freeze-up on reservoirs. The main method of work in the lesson is a conversation, which can be based on the following questions and tasks.

View records of weather observations. Mark the date when the snow fell and did not melt again. So you can determine the approximate time for the end of autumn. Was the weather varied in autumn? Which one? What are the changes in the weather associated with in the fall? What other changes took place in inanimate nature in autumn? Compare the temperature and type of precipitation on days when it snowed and on days when it rained. Establish a relationship between air temperature and the type of precipitation.

How did the height of the Sun change during the fall? Is there a relationship between air temperature and the height of the Sun? Prove your opinion. How did the length of the day change during the fall? Is it related to the Sun? Could a change in the height of the Sun affect other changes in nature? How exactly?

What changes have occurred in the life of plants in the fall? What month can be called "golden autumn"? Which month is the most deciduous? Compare changes in plant life with changes in non-living nature. Link these changes.

How has the life of wild and domestic animals changed in the fall? How are these changes related to other changes in nature?

What have you learned about people's relationship to nature? What conclusions did you draw from this? Why should nature be protected in autumn? How are nature protected in the area where you live? What plants and animals in your area are especially protected? If there is a nature reserve in your area, tell us about its activities and role in nature conservation.

What is the specificity of people's autumn labor? Prove by examples that the work of people depends on the weather, changes in the life of plants and animals. What is your participation in the autumn labor?

Highlight the main signs of summer and autumn in the nature of your area.

In the course of the discussion of these issues, to confirm the stated provisions, it is necessary to involve the personal observations of children, the illustrative material of the textbook and specially selected by the teacher for this lesson. Speaking about the state of objects and natural phenomena in autumn, one should establish the causes and relationships in nature, discuss the attitude of people to nature and measures for its protection.

In conclusion, the main features of summer, then autumn, are highlighted, which are compared with the characteristics of these seasons in the textbook.

The final conclusion from the lesson can be formulated something like this: “In summer it is warm, precipitation in the form of rain. Plants are green, many of them bloom, fruits and seeds ripen. Animals are active. There is enough warmth and food for them. People take care of crops and plantings, harvest crops, prepare animal feed.

It is colder in autumn, precipitation in the form of rain and snow. Plants have a change in the color of the leaves and leaf fall. Insects disappear (hide), birds fly away. People finish harvesting and storing crops. "

The homework for this lesson may be limited to a suggestion to continue observing in nature. In terms of the content of the topic, the assignment may not be at all if the students have sufficiently mastered the educational material, completed the practical part in the workbook. It can be given to individual students who have not learned or completed something. All students may be given the task to repeat some insufficiently learned question.

Types and structure of science lessons

In modern conditions of school reform, teachers who promote developmental education warn against universalizing any external structure of the lesson. “At the same time, the structure of a lesson cannot be amorphous, impersonal and random. The structure of each lesson in accordance with its logic should be clear, with a strict transition from one part of the lesson to another in accordance with the didactic goal of the lesson and the laws of the learning process. "

An attempt to classify the lessons, breaking them down into several simple types, was undertaken by KD Ushinsky. He argued that only an intelligent system, emerging from the very essence of objects, gives a lasting power over our knowledge. Ushinsky singled out mixed lessons, on which the knowledge gained earlier is repeated, new material is studied and consolidated; oral, written and practical exercises lessons, the purpose of which is the repetition of knowledge, the development of skills and abilities; knowledge assessment lessons held at the end of a certain period of study.

V.V. Polovtsov wrote in his textbook "Fundamentals of General Methods of Natural Science" that the course should be based on a certain system, in which connections should be natural, causal, and not purely external, artificial. The question about the system was also raised in the book by B. Ye. Raikov "General methodology of natural science". The author noted that the goal and plan of any lesson can be correctly outlined only if we clearly understand the structure of the entire program and clearly see the place of the lesson we are developing in the series of those preceding and following it.

The question of the competent construction of the lessons will be correctly resolved only if their typology is well thought out. The types of lessons depend on their didactic purpose, content and place in the structure of the study of the topic. Each topic of the program is a system of logically related lessons.

There are various approaches to classifying lessons. Lessons are classified depending on the didactic goal (I. T. Ogorodnikov), content and methods of conducting (M. I. Makhmutov), ​​teaching methods (I. N. Borisov), the main stages of the educational process (S. V. Ivanov).

The didactic goal is the most important structural element of the lesson, therefore, the classification on this basis is the closest to the real educational process. For example, N.M. Verzilin and V.M. Korsunskaya distinguish introductory lessons, lessons revealing the content of the topic and final or generalizing.

I. T. Ogorodnikov identifies the following types of lessons: learning new knowledge, consolidation, exercises and practical work, laboratory, repetitive and generalizing, synthetic.

OV Kazakova rightly objects to highlighting the lesson "learning new knowledge". “In essence, in all lessons, with the exception of control ones, of course, new knowledge is communicated and in all or almost all lessons, they are reinforced.” A synthetic lesson is inherently synonymous with a mixed or combined type of lesson.

Most primary school methodologists identify the following types of science lessons:

1) introductory;

2) subject;

3) combined;

4) generalizing.

Each type of lesson has a certain structure, which depends on its goals, the content of the educational material, methods of conducting and is determined by the sequence of interrelated stages of the lesson.

Introductory Lessons are conducted at the beginning of the study of a course, section or large topic. For small topics, the teacher gives an introduction at the beginning of the first lesson.

The main didactic goals of such lessons are as follows:

1. To establish the level of preparation of students for the perception of new knowledge, to systematize the existing knowledge.

2. To form a general idea of ​​the content of the educational material that the children will study in subsequent lessons.

3. To acquaint students with the features of the construction and methods of studying a new topic (section, course) in the textbook.

4. Arouse children's interest in a new topic (section, course). Pose a few new problems and leave them open.

Introductory lessons can be structured as follows:

1) class organization;

2) setting educational tasks;

3) familiarization with the goals, content, structure of the section (topic) in the textbook;

4) actualization of existing knowledge;

5) the formation of new ideas and concepts;

6) practicing techniques for working with a textbook;

7) homework;

8) the result of the lesson.

Let us give an example of an introductory lesson on the topic "What is nature"(A. A. Pleshakov's third grade natural history program).

Goals:

1. To form a general idea of ​​nature and its meaning for humans. To achieve the assimilation of knowledge about objects of inanimate and living nature and the differences between living and nonliving.

2. To develop the ability to work with a natural history textbook, to draw up a model of the relationship between nature and man.

3. To carry out ecological education of junior schoolchildren on the basis of the formation of ideas about natural relationships.

Equipment: various bodies of inanimate and living nature, cards for drawing up the model "The value of nature for man."

During the classes

1. Statement of educational tasks.

In the lesson, children should learn what relates to nature, how living things differ from non-living things. Learn to establish relationships within nature and between man and nature. To solve these problems, the teacher invites children to get acquainted with the textbook "Natural Science" and learn how to work with it.

2. Acquaintance with the textbook, with the tasks and contents of the first section.

Children look at the cover of a textbook, read the author's address to a third grader. They try to explain the expression "Nature and people are one whole", which was encountered in circulation. The title page is used to familiarize oneself with the sections of the book.

On the shmuttitule, children read the title of the first section, its tasks, content, and determine the topic of today's lesson.

3. Systematization of existing knowledge.

A short conversation based on the knowledge gained in the course of 1–2 grades. Children look at the colorful spread of the textbook ... The teacher asks to list, taking into account what is seen in the picture, what belongs to inanimate and living nature. Draws attention to the fact that children do not classify objects made by man as nature. It is advisable at this stage of the lesson to demonstrate the school telescope and microscope and object visual aids.

4. Formation of new ideas and concepts. Practicing techniques for working with a textbook.

What belongs to nature. Nature is inanimate and alive.

It is discussed how living things differ from objects of inanimate nature. The teacher clarifies and complements the children's answers.

You can then invite students to complete the diagram, part of which is on the board, using the body text of the textbook:

Scheme 5

At the end of the work, the following entry appears on the board:

This stage of the lesson can be completed by the students' answer to the question under the heading “Think!”.

In nature, everything is interconnected.

You can invite students to give several examples proving that living nature cannot exist without inanimate; living nature affects non-living nature; plants are essential for animal life; animals influence the life of plants. If necessary, the children's answers are clarified with the help of the textbook.

The value of the surrounding nature for people.

Building a dynamic circuit on a magnetic board or flannelgraph. Various elements of the model designate the ecological (water, food), aesthetic (butterfly), hygienic (a person under the shower), practical (furniture), moral (planting trees), cognitive (magnifying glass) value of nature. The teacher sequentially shows pictures and asks to explain what meaning of nature is "encrypted" in them. The one of the students who will most accurately do this places a sign on a magnetic board, pointing the arrow towards the person. After completing the drawing up of the model, one of the students uses it to talk about the role of nature in human life. The student's story can be composed in accordance with the paragraph of the textbook.

5. Homework.

Answer the Test Yourself questions using the main text of the tutorial. In the figure under this heading, figure out what belongs to nature and what does not; what is inanimate and what is in living nature. One of the tasks can be performed at your choice.

6. Summing up the lesson.

The teacher finds out what the children learned in the lesson, what they learned.

Students are invited to formulate the main conclusions on the content of the lesson, which are compared with the conclusions of the textbook.

At the end of the lesson, the "announcement" reads "In the next lesson ...". It is given in a form that is intriguing for a child and makes one think about questions that actualize the life experience of children.

With the correct structure of the introductory lesson, students will look forward to subsequent lessons on this topic.

Subject lessons imply the work of students with objects of nature or teaching devices. There is always practical work in such lessons. The selection of this type of lesson is due to the specifics of the content of the initial course in natural science.

Goals subject lesson:

1. To achieve the assimilation of new knowledge through direct work of students with objects of nature.

2. To develop practical skills in conducting the simplest natural scientific research.

This type of lesson requires a lot of prior preparation. The teacher should select the handout in advance. If necessary, then start experiments (for example, when studying the development of a plant from a seed). You should first do the frontal experiments yourself in order to track how much time is spent on them.

Subject lessons have the following approximate structure:

1) class organization;

2) communication of the topic and setting of educational tasks;

3) updating basic knowledge;

4) carrying out practical work;

5) consolidation;

6) homework;

7) the result of the lesson.

Let us give example of a subject lesson on the topic "What are the soils"(A. A. Pleshakov's class 4 natural history program).

Goals:

1. To give an idea of ​​the most important types of soils in their region.

2. To develop the ability to distinguish between chernozem and podzolic soils, to work with soil collections.

3. To cultivate respect for the soils of their native land.

Equipment: collection "Soil" (handout); Soil Profiles table; physical or soil map of your region.

During the classes

1. Statement of educational tasks.

In the lesson, students should learn what soils are and learn to distinguish between the types of soils in their region.

2. Repetition of basic knowledge.

Students remember where the life of each plant begins and ends; what non-living and living components are included in the composition of the soil; what constituent part of the soil ensures its fertility.

The teacher asks you to answer the question: "Why did the scientist V. V. Dokuchaev call the soil a person's breadwinner and considered it more valuable than any mineral?" Summarizing the children's answers, he says that the soils of any area of ​​our country are a national wealth, therefore people should know and protect the soils of their land.

3. Conducting practical work.

Is put goal: find out what kind of soil there are and what types of soil prevail in their native land.

In his opening remarks, the teacher says: “You have been in the field, in the meadow, in the forest more than once and, probably, have noticed that the color of the soil is not the same everywhere. In fields and meadows, the soil is usually black, while in the forest it is gray or yellowish gray. You guessed it , what does the color of the soil depend on? You have to find out this in practical work. "

Students work with the Soil Collections in the following assignments:

1) Consider black soil in the collection. What are their names?

2) What constituent of the soil makes it black? (Find humus in the collection and compare its color to the color of the soil.)

3) What is the main property of the soil associated with the content of humus in it?

It is reported that the most fertile soils are black earth. They are especially rich in humus.

On a physical or soil map of the region, the teacher shows what territory is occupied by chernozems. It reports that almost all chernozem soils are plowed up for agricultural crops.

4) Find in the collection and examine podzolic soils. What color are they?

5) Compare the color of podzolic and chernozem soils. Which soil contains more humus? Why do you think so? Which soils are more fertile?

6) What substance gives grayish color to podzolic soils? (Compare the color of the soil to that of sand and clay.)

The teacher shows on the map the edge where the podzolic soils are located, and informs them that mainly coniferous forests grow on them.

An intermediate position between chernozem and podzolic soils is occupied by gray forest soils. The thickness of the humus layer in them reaches 30 cm. They are associated with herbaceous deciduous forests. There are other types of soil, but students learn about them in higher grades.

During the practical work on the board, the diagram "Types of soils" is filled in. Children draw up such a diagram in a workbook.

At the end of the work, the students describe the types of soils of the region and conclude that their color and fertility depend on the composition.

4. Consolidation of the acquired knowledge and skills.

Using a picture in a textbook or a table, students compare soil profiles, read the text of a natural history textbook on soil types and answer questions under the heading "Check yourself"; learn to recognize the different types of soil in the collection.

5. Homework.

To prepare for the next lesson, the teacher asks you to review the third grade material about what plants take from soil and how soil is formed.

Combined lessons the most common in training practice. These are lessons of this type, on which new material is studied and consolidated, continuity with previously studied is established. They combine several didactic goals of equal importance:

1. Review and organize previously studied material.

2. To achieve the assimilation of new ideas and concepts.

3. Develop practical skills.

4. To consolidate the acquired knowledge and skills.

In such a lesson, you can use combinations of building blocks of different types of lessons.

Let us give an example of a combined lesson on the topic "Animals of the reservoir". This is the second lesson of the topic "Water body - natural community" (program A. A. Pleshakov, grade 4).

Goals:

1. To achieve the assimilation of knowledge about animals of various groups living in a fresh water body. To form an idea of ​​the reservoir as a natural community.

2. To develop the ability to establish ecological links between plants and animals of a fresh water body, between the inhabitants of the water body and the environment.

3. To cultivate respect for the inhabitants of reservoirs.

Equipment: herbariums and drawings depicting plants, images and collections of mollusks, insects, fish and other inhabitants of the reservoir. If the class has an aquarium, then it can serve as a model for the natural community.

During the classes

1. Statement of educational tasks.

At the end of the lesson, children should know what animals live in the reservoir and how they relate to the environment; be able to establish the relationship between animals and plants.

2. Checking homework.

The teacher asks the children to draw a model of a fresh water reservoir using drawings depicting plants on the board, placing them on the "floors". Students briefly describe the plants in the water body, highlighting the signs of adaptability to life in the water.

3. Learning new material.

The main problem of the lesson is formulated: "To prove that a fresh water body is a natural community."

When studying new material, the model of the reservoir depicted on the board is "populated" by animals. Students read texts about animals of various groups in the textbook. The teacher gives additional information about the inhabitants of the reservoirs of his region, talks about the protected animals.

Students write down the names of animals that live at different levels of the reservoir in a notebook.

4. Consolidation of knowledge. Establishing continuity with previously studied material.

At this stage of the lesson, children solve the problem posed to them, establishing the following relationships between the inhabitants of the reservoir:

- by habitat (talk about the role of plants in the dispersal of animals);

- according to the method of feeding (they make up several food chains in a notebook that have developed in a reservoir);

- on the participation of animals in the spread of plants (talk about the methods of distribution of some plants, for example, elodea);

This activity will help students to ensure that the body of water is a natural community.

5. Homework.

Generalizing lessons are carried out at the end of the study of a large topic or section.

Goals summary lesson:

1. To generalize and systematize the knowledge of children.

2. To work out the acquired skills and abilities.

3. Learn to apply knowledge and skills in new situations.

4. To establish the level of assimilation of program material and mastery of practical skills.

The traditional structure of such a lesson is as follows:

1) class organization;

2) generalization and systematization of knowledge on the studied topic;

3) development of skills and abilities in the process of independent work;

4) the use of ZUNs in a new learning situation;

5) generalizing conversation;

6) the result of the lesson.

Generalization lessons are often taught in an unconventional way. These are competition lessons ("What, where, when", "KVN", etc.), travel lessons ("Traveling through the natural zones of Russia", "Geological expeditions around the native land", etc.), business games ("Environmental conference", "If I were the head of the enterprise", etc.). It is recommended to organize group or individual independent work of students on them.

Here is an example of a generalizing lesson on the topic "Mineral resources of your land" (program A. A. Pleshakov, grade 4).

Goals:

1. To generalize and systematize the knowledge of children about the most important minerals of their region.

2. To practice the ability to recognize and organize minerals according to their physical properties.

3. To cultivate a respectful attitude towards underground resources.

Equipment: for each group: collections of minerals, contour maps of their region, conventional signs of minerals, local history literature; at the teacher: products from minerals of their area (or their images), a physical map of the area (edge).

During the classes

The lesson can be organized in the form of a geological expedition, after which the children prepare a report on the work done, filling in the table "Properties of minerals" in the workbook and applying conventional signs of minerals on the contour map of the region (edge).

Students work in groups of 4-5. In each group (team) the "expedition leader" (team captain), "cartographers", "geologists" are selected.

1. Conducting competitions.

In the lesson, several competitions are held, which are evaluated by a jury selected by the teacher.

Geologists competition.

Each team is given cards with the names of two minerals (the names can be encrypted). Geologists must find them in the collection and describe the properties.

At the end of the work, the leader of the expedition of each team talks about the properties of their minerals, without naming them. The rest of the description teams determine the name of the mineral and find it in the collection. Each group has the right to ask the leader two questions each, helping to guess which mineral is in question.

Cartographers competition.

After the correct answer, cartographers attach a conventional sign of a mineral to a physical map and plot it on a contour map.

Students are given 10-12 minutes for this work. Points are awarded both for a competent description of their fossils, and for the correctly guessed name of a mineral from the rival team.

Captains competition.

Each "expedition leader" is asked, for example, two entertaining questions related to minerals. If it is difficult to answer, he can turn to the team for help. The jury evaluates each answer.

Other contests can also be held.

2. The generalizing story of the teacher.

The teacher talks about the use of minerals at the enterprises of the region. At the same time, he demonstrates the products produced on them, tells how the region is connected with other regions of Russia and abroad.

3. Summing up.

At the end of the lesson, the jury sums up the results and awards prizes to the best teams.

When organizing lessons of the latter type, the teacher must remember that in order to generalize the material it is necessary: ​​to highlight the main thing in it; describe the leading concepts; compare them with each other; establish causal relationships; find general patterns; formulate conclusions.

The characterization of natural science lessons will be incomplete if we do not dwell in more detail on the features of their structure in various educational systems.

Topic 8. Forms of organization of teaching natural science in primary school

Plan:

1. The concept of the form of education. Classification of forms of education.

2. The concept of the lesson.

3. Characteristics of the main types and types of natural science lessons.

Main content

The concept of the form of education. Classification of forms of education.

There are several definitions of the concept of "form of education".

Form of study- the way of organizing the educational activities of schoolchildren. Petrosova R.A. highlights: lesson, laboratory and practical work, extracurricular work, homework, extracurricular work, excursions.

Form of study- the way of organizing the educational activities of schoolchildren. Mironov A.V. highlights: a lesson, excursions, systematic observations in nature, practical work (on the ground, school area, corner of nature), holidays, green patrols, etc.

Organizational form of training- the external side of the learning process, answering the questions: when, where, how much and how this process takes place. N.F. Vinogradova highlights: a lesson, excursions, homework, extracurricular activities (electives, excursions, circles, leisure evenings, meetings, competitions).

Form of teaching- the organization of educational and cognitive activities of students, corresponding to various conditions for its implementation (in the classroom, in nature), used by the teacher in the process of upbringing education. (Verzilin N.M.).

G. N. Aquileva, Z. A. Klepinina distinguish 3 groups of forms of education:

Output: approaches to the definition of the "form of education" are ambiguous. For example, there is no consensus on whether to consider games, students' independent work, etc. as a method or form.

Lesson concept.

The lesson as a form of education has existed for over 300 years. It has its characteristic signs:

- is conducted with a constant group of students of a certain age and approximately the same level of training;

- the lesson is held for a limited time (35 or 40-45 minutes);

- performs educational, upbringing, developmental, stimulating and self-educational functions (although this division of functions is conditional).

The structure of the lesson changes depending on the type of lesson, its content and the applied methodology.

Features of the lessons of natural science (the world around).

1. Lessons require greater relaxedness of children, ensuring for each child the opportunity to freely express their emotional state.

2. Wherever possible, lessons should take place in the environment that is being studied.

3. The variety of activities of children in the lesson (play, visual activity, conversation, discussion, etc.), each of which requires a different organization (children sit, stand, work in pairs or individually, get a general or individual result, etc.). ).

In the lyceum, the fourth year in the senior classes of the humanities profile, the subject of natural science was introduced (3 hours a week) instead of courses in physics, chemistry, biology. An integrated course "Natural Science, Grades 10-11" was taken for approbation, edited by I.Yu. Aleksashina, designed for two years of study (210 hours). Based on the program of the course, a calendar-thematic plan is drawn up,

The main objective of the course is to form, on an interdisciplinary basis, general scientific and general intellectual abilities and skills, an integral natural-scientific picture of the world. The course program is developed on a unified methodological basis: the study of natural science objects in the system "nature - science - technology - society - man". The methodological concept of the course provides for the organization of materials in accordance with different forms of educational activity.

Natural science is a new academic subject. And the difficulties of mastering it by the teacher are explainable: the methodological base of the course is not sufficiently developed, there is no criterion-diagnostic material, it is difficult to be a specialist in physics, chemistry, biology at the same time, to have synergistic thinking. The students of humanitarian classes also had difficulties in mastering the integrated course: a small stock of knowledge and low educational motivation to study the subjects of the natural cycle.The main problem of the teacher was how to convey to the humanities the most complex natural science material in a simple and accessible way, but without reducing scientific accuracy. Moreover, there is no mathematical apparatus in the course (no equations, formulas). There was a search for educational technologies that would facilitate the successful appropriation of the main ideas of the course by students. These are information and communication technologies (using the capabilities of the lyceum website, creating the Natural Science website, preparing presentations), technologies for project activities, development of research activities, and others. In addition, various types of diagnostic materials have been developed, taking into account the intellectual characteristics of students. All this helped to form plans and outlines of lessons in natural science at a level corresponding to the current state of science and pedagogical concepts. Also, together with the students of the class, educational and methodological materials were developed, which undoubtedly increased the interest of students in the humanities in the complex course of natural science and the formation of a natural scientific worldview. We offer our lesson on the topic “Devices using the corpuscular properties of light. Photo effect "

Theme:"The interaction of science and technology" 5 lesson.

I. Organizational stage.

Good afternoon everyone! We we continue our acquaintance with the topic "Interaction of Science and Technology" and, today we will study an interesting physical phenomenon "photoelectric effect". Write down the topic of the lesson and think about the word "photo effect". What is the meaning of this word? Answer: consists of two words photo - light (from Greek), effect (from Latin) action, therefore "photoeffect" is the action of light. - That's right, and if this is an action, then our task for today is to find out: what effect can light produce with matter, what laws it obeys, what characteristics it depends on and where it found application.

Lesson plan:

1. Protection of collective presentations and creation of an interdisciplinary project "Photoeffect"
2. Summing up the presentations
3. Testing on this topic in remote mode.

II. Statement of the educational problem.

Now we have to create a collective interdisciplinary project "Photoeffect" from classmates' presentations. We post this project on the lyceum website for everyone to see - it is a big responsibility. How to evaluate the quality of the presentations? Yes. According to certain criteria.

Together with the students, criteria for evaluating work are developed ( Annex 1)

III. Generalization and systematization of knowledge.

In the previous lesson, the students got involved in the creation of the interdisciplinary project "Photo Effect". ( Appendix 3) The class was divided into groups of 3 people, chosen message topics. Presentation topics:

1. The history of the discovery of the photoelectric effect.
2. Photon, particle or wave?
3. The photo.
4. Photosynthesis.
5. Impressionism.
6. Devices using the corpuscular properties of light.

Students defend group presentations ( Appendix 4), which were performed at home All other students listen carefully and fill out the form "Protection of presentations" (Appendix 1), ask clarifying questions.

IV. Summing up protection of presentations.

Students assess presentations. After the remarks made by classmates. pupils correct their work. Then a collective project "Photoeffect" is created, which is posted on the WIKI-site as a tool for collaboration. Students feel a certain pride that their work is displayed on the site of the lyceum, for public viewing.

V. Independent work-testing.

The test on the subject "Photoeffect" is posted on the Lyceum's website.

If the discussion of the work has dragged on, then the students can perform the testing at home at their computer (element of distance learning). If there is enough time in the lesson (10 minutes), then each individual, using a computer, performs the test. Test execution. ( Appendix 2)

Vi.Reflection.

The process of self-knowledge by students of their mental states and emotions caused by the lesson. Reflection: Express your attitude to the lesson - choose an emoticon that matches your mood.

Analyze your feelings and feelings during the lesson.
