The CRC is designed for self-control of students in grades 7-9 in the main sections of the computer science course (UMK Bosovoy L.L.), including the test for the demo version of the OGE-2016. The test questions use questions with one correct answer, with several correct answers, with the input of a numerical value and for establishing a match. The product is designed as web pages.

The test form of monitoring the success of the educational process acquires actual importance in connection with the use of this form in the State Final Attestation and with the introduction of the Federal State Educational Standard, in which the priority of the quality of the educational process is defined as one of the main priorities. To prepare students for this form of checking the level of learning, it is necessary to introduce this procedure into the system, in the constant monitoring of the results of educational activities. And not only in graduation classes, but also in other periods of the educational process.

In systematic preparation, it is better to use not blank technology, but computer testing, which not only optimizes control, but also contributes to the accumulation of results and their subsequent analysis. It can be used for the current, midterm and final examination of knowledge.

The purpose of creating this information resource is to provide students with the opportunity in a form convenient for them to check the level of mastering theoretical material and the ability to apply their knowledge to solve problems.

The product is intended for self-control of students in grades 7-9 in the main sections of the computer science course (the distribution of topics corresponds to the teaching materials of L.L. Bosova). The kit includes a test for the demo version of the control measuring materials OGE 2016.

Tests perform not only a controlling, but also a teaching function, since there is an opportunity to see incorrect answers and correct your decision after additional study of the material.

The product is made in the form of web pages, which allows you to use it on any computer, copy to students on flash drives, place it on a local network or on a website on the Internet.

After running the index .htm file, the main page will open with a menu for selecting tests.

Menu items are hyperlinks to their respective test pages. The tasks use questions with one correct answer, with several correct answers, with the input of a numerical value or a string, and to establish a match.

After answering ALL questions, you should click on the "Check answers" button. A window will appear with the results in percent and on a 5-point scale. Questions with incorrect answers will be highlighted in red.

Attention! If your browser is blocking scripts and ActivX controls, you must allow blocked content.

The tests were developed on the basis of assignments from textbooks and workbooks of the teaching materials of L.L. Bosova and materials from the Federal Institute for Pedagogical Measurements (FIPI).

When creating the tests, the NetTest program was used (by K. Polyakov).

Explanatory note

6 variants of final tests for assessing the quality of training of graduates of basic school are presented. Each option contains 24 questions, with the help of which the teacher can check the quality of assimilation of the passed material. For each question, 4 possible answers are offered, from which you should choose the correct one. The questions are selected in such a way that it is possible to determine the quality of the preparation of students in all topics of the computer science course included in the mandatory minimum of the educational content. The number of questions in each option may vary. The main thing is that each variant of the final test fully covers all the theoretical and practical material of the course, included in the mandatory minimum content.

Test execution time: 30 min.

Evaluation criteria:

Number of correct answers

Less than 10

10 – 14

GDZ control and measuring materials (kim) in informatics Grade 9 Maslenikov Wako

• You can prepare for the GIA in informatics by regularly working through several sections and topics of the educational material. As practice shows, the tasks submitted for the exam are standard. The format is changing (now - on a PC) and the block of theoretical questions. Systematic testing, self-examination of one's knowledge helps to master the latter qualitatively and competently. To implement such plans, you will need a good educational material and a resource book for it. Periodically assessing the dynamics, checking the accuracy of the answers received by GDZstudying the correct writing, ninth-graders approach the final test with sufficient knowledge.
• Among the effective and understandable manuals - control and measuring materials (CMM) in informatics for grade 9, the author Maslenikova O. N. The tests offered in them are well systematized, suitable for almost any theoretical textbook on the discipline. The collection can be used for preparation in the classroom, at home, including for classes with a tutor, in circle work with high school students. The main thing is a systematic approach to checking knowledge, periodically monitoring their dynamics and returning to those topics that caused the greatest number of questions and difficulties during the previous control.
