to conduct a unified state exam in 2017
in PHYSICS

1. Appointment of KIM USE

The Unified State Exam (hereinafter - the Unified State Exam) is a form of objective assessment of the quality of training of persons who have mastered educational programs of secondary general education, using tasks of a standardized form (control measuring materials).

The Unified State Exam is conducted in accordance with the Federal Law of December 29, 2012, No. 273-FZ "On Education in the Russian Federation".

Control measuring materials allow to establish the level of mastering by graduates of the Federal component of the state educational standard of secondary (complete) general education in physics, basic and profile levels.

The results of the unified state exam in physics are recognized by educational organizations of secondary vocational education and educational organizations of higher vocational education as the results of entrance examinations in physics.

2. Documents defining the content of the KIM USE

3. Approaches to the selection of content, the development of the structure of the KIM USE

Each version of the examination paper includes controlled elements of content from all sections of the school physics course, while assignments for all taxonomic levels are proposed for each section. The content elements most important from the point of view of continuing education in higher educational institutions are controlled in the same version by assignments of different levels of complexity. The number of assignments for a particular section is determined by its content and proportional to the study time allotted for its study in accordance with the approximate physics program. The various plans, according to which the examination variants are constructed, are built according to the principle of substantive addition so that, in general, all series of variants provide diagnostics of the development of all the content elements included in the codifier.

The priority in the design of CMM is the need to check the activities provided for by the standard (taking into account the limitations in the conditions of mass written testing of students' knowledge and skills): mastering the conceptual apparatus of a physics course, mastering methodological knowledge, applying knowledge in explaining physical phenomena and solving problems. The mastery of skills in working with information of physical content is tested indirectly using various methods of presenting information in texts (graphs, tables, diagrams and schematic drawings).

The most important activity from the point of view of successful continuation of education at a university is problem solving. Each option includes tasks for all sections of different levels of complexity, allowing you to test the ability to apply physical laws and formulas both in typical educational situations and in non-traditional situations that require a sufficiently high degree of independence when combining known action algorithms or creating your own plan for completing an assignment ...

The objectivity of checking tasks with a detailed answer is ensured by uniform assessment criteria, the participation of two independent experts evaluating one work, the possibility of appointing a third expert and the presence of an appeal procedure.

The Unified State Examination in Physics is an exam of the choice of graduates and is intended for differentiation in admission to higher educational institutions. For these purposes, the work includes tasks of three levels of complexity. Completing tasks of the basic level of complexity allows you to assess the level of mastering the most significant content elements of the secondary school physics course and mastering the most important types of activity.

Among the tasks of the basic level, tasks are distinguished, the content of which corresponds to the standard of the basic level. The minimum number of USE scores in physics, which confirms that a graduate has mastered a secondary (complete) general education program in physics, is established based on the requirements for mastering the basic level standard. The use of tasks of increased and high levels of complexity in the examination work makes it possible to assess the degree of a student's preparedness for continuing education at a university.

4. The structure of the KIM USE

Each version of the examination work consists of 2 parts and includes 32 tasks that differ in form and level of difficulty (table 1).

Part 1 contains 24 tasks, of which 9 tasks with the choice and recording of the number of the correct answer and 15 tasks with a short answer, including tasks with self-recording of the answer in the form of a number, as well as tasks for establishing correspondence and multiple choice, in which answers are required write down as a sequence of numbers.

Part 2 contains 8 tasks, united by a common type of activity - problem solving. Of these, 3 tasks with a short answer (25-27) and 5 tasks (28-32), for which it is necessary to give a detailed answer.

In order for teachers and graduates to have an idea of ​​the CMM of the upcoming USE in physics, demo versions of the USE in all subjects are published on the FIPI official website every year. Everyone can get acquainted and get an idea of ​​the structure, volume, approximate tasks of real options.

When preparing for the Unified State Exam, graduates are better off using options from official sources of information support for the final exam.

Demonstration version of the exam 2017 in physics

Demo versions of the exam in physics 2016-2015

Total tasks - 31; of them by the level of difficulty: Basic - 18; Increased - 9; High - 4.

The maximum primary score for a job is 50.

Total time to complete the work - 235 minutes

The approximate time for completing tasks for various parts of the work is:

1) for each task with a short answer - 3-5 minutes;

2) for each task with a detailed answer - 15-25 minutes.

Additional materials and equipment A non-programmable calculator (for each student) with the ability to calculate trigonometric functions (cos, sin, tg) and a ruler is used. The list of additional devices and materials, the use of which is permitted for the Unified State Exam, is approved by Rosobrnadzor.

When reviewing the demo version of the 2017 USE in physics, it should be borne in mind that the tasks included in it do not reflect all the content issues that will be checked using the CMM options in 2017.

Changes in the KIM USE in physics in 2017 compared to 2016

The structure of part 1 of the examination paper has been changed, part 2 is left unchanged. Tasks with a choice of one correct answer were excluded from the examination work, and tasks with a short answer were added.

When making changes to the structure of examination work in physics, the general conceptual approaches to the assessment of educational achievements have been preserved. Including, the maximum score for completing all tasks of the examination work remained unchanged, the distribution of maximum points for tasks of different levels of complexity and the approximate distribution of the number of tasks for the sections of the school physics course and methods of activity were preserved.

A complete list of questions that can be controlled at the 2017 unified state exam is given in the codifier of content elements and requirements for the level of training of graduates of educational institutions for the 2017 unified state exam in physics.
