Year. Officials did not pass by and USE in physics. 2017 will bring several innovations to this exam that can affect the overall performance of students and reveal the true picture of their knowledge.

The main amendment is the exclusion of the test part. It is worth noting that this innovation will occur not only in the physics exam, but also in many others (history, literature, chemistry).

The main changes in the USE-2017

A few months ago it became known that the deputies are seriously thinking about adding another discipline to the list of compulsory subjects submitted for the Unified State Examination. In total, their total number will increase to three.

Until 2017, students at the end passed the Russian language and mathematics, as well as additional subjects necessary for admission to a university for a certain specialty. Starting next year, for the title compulsory subject claims first.

Civil servants, from whose submission the above innovations were made, justify their act by the fact that at present too few students have a decent knowledge in the field of national and world history. Few of them are interested in the past and do not know how their ancestors lived and how they “built” the state. According to them, such a trend cannot be called positive, and if appropriate measures are not taken, very few worthy educated citizens will remain in the country in the near future.

What will change in the physics exam?

Let's look at the exam in physics. This subject will not receive special amendments. The only thing to pay attention to is the exclusion of the test block. In its place, they plan to put an oral and written method of answering. It is too early to talk about any specific details on this issue, exactly the same as about what can be included in the tasks submitted for the exam.

As for the cancellation of the test part, it is worth noting that the officials did not come to this decision overnight. For many months there were heated negotiations in Rosobrnadzor regarding the advisability of this amendment. All pros and cons were weighed and carefully discussed.

Ultimately, as we see oral part decided to implement in many final tests. The most important advantage of this approach to testing knowledge is the exclusion of guessing or, as the people say, the “poke method”. Simply put, now it will not be possible to rely on “maybe lucky” and put the answer at random. In turn, the written and oral answers of the student will be able to show the examiner his level of education, as well as his ability to learn.

Date of the exam

There is not much time left before the start of the tests, so now you can familiarize yourself with official timetable. So, the exam in physics in 2017 will be held on the following dates:

The early period is March 22 (Wednesday). Reserve day - April 5th.
The main period is June 13 (Tuesday). Reserve day - June 20.

The importance of the exam in Russia in the future

Note that in the next few years, the procedure for holding the Unified State Exam in Russia will change radically. The test part will be removed in all subjects and this is not the limit.

Closer to 2022, Rosobrnadzor intends to expand the list of compulsory disciplines to four. Most likely, it will be a foreign language, because in our time, knowledge, for example, in English is incredibly valued and gives a chance to apply for a prestigious high-paying position.

In addition to English, it will be possible to take German, French and Spanish.

You can already guess what the future of education will be like in Russian Federation. IN currently even common man It can be seen that the world and the trends in it are changing every day. What was previously unimportant comes to the fore. IN modern society the ability to establish connections, as well as the manifestation of diplomacy, is incredibly appreciated.

To maintain business relations with people of another nation, it is necessary Fluency several languages. Only by communicating with a person in his native dialect, it will be possible to establish close, trusting relationships. In fact, for this already now in Russian schools great attention is paid to foreign languages and their study among students.

How to prepare for the exam

Given the fact that physics is a complex subject and cannot be on a par with the Russian language or literature, eleventh graders should devote a little more time to it than to the rest of the subject. This is due to the fact that understanding a particular topic can take a long time, and without understanding a good result on the exam, you can forget. In addition, if you want to enter a prestigious university, knowledge in the field of physics is extremely important.

It is worth noting that there is a category of people who claim that the USE will be canceled in 2017. No need to mislead yourself and others - there will be no cancellation! And for the next 5-6 years, one can only dream of such a thing. Besides, for what to exchange something like an exam? Despite all its severity, the exam is able to show real level knowledge and preparing the student for adult student life.

Where do you get knowledge from?

You can prepare for the exam in physics according to the same principle by which you plan to prepare for other subjects. First of all, of course, you should pay attention to educational materials: books and reference books. While studying at school, the teacher is obliged to give a huge amount of knowledge, which can later be used on. The main thing is to listen carefully to the teacher, ask again and understand the essence of the material presented.

Stock up on a collection of basic physical formulas so that this part of the exam does not become intimidating for you. Another tool for preparing for the exam in physics can be a collection of problems. It prints various problems with solutions that can be used as training. Of course, there will be completely different tasks on the test, but having got your hand in solving physical problems, the examination paper will not seem so difficult to you.

You can start going to a tutor, as well as study on the Internet on your own. Now there are a lot of online resources with which you can understand how the physics exam will actually take place.

Any of your efforts will once again prove that at this stage of life, the main thing for you is studying and you will do everything to make it successful!

The Unified State Examination in Physics is an exam of the choice of graduates and is designed to differentiate when entering higher educational establishments. For these purposes, tasks of three levels of complexity are included in the work. Completing tasks basic level complexity allows you to assess the level of development of the most significant content elements of the course of physics high school and mastery of the most important activities. The use of tasks of increased and high levels of complexity in the USE makes it possible to assess the degree of student's preparation for continuing education at a university.

Each option examination work consists of 2 parts and includes 32 tasks that differ in form and level of complexity (see table).

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

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

Distribution of tasks by topics

When developing the content of KIM, the need to check the assimilation of knowledge in the following sections of the physics course is taken into account:

Mechanics(kinematics, dynamics, statics, conservation laws in mechanics, mechanical oscillations and waves);
Molecular physics (molecular-kinetic theory, thermodynamics);
Electrodynamics and fundamentals of SRT(electric field, D.C., magnetic field, electromagnetic induction, electromagnetic oscillations and waves, optics, fundamentals of SRT);
The quantum physics(particle-wave dualism, physics of the atom, physics of the atomic nucleus)

The total number of tasks in the examination paper for each of the sections is approximately proportional to its content content and the study time allotted for the study of this section in the school physics course.

Distribution of tasks by difficulty level

The exam paper contains tasks different levels difficulty: basic, advanced and high.

Basic level tasks are included in part 1 of the work (19 tasks, of which 9 tasks with the choice and recording of the number of the correct answer and 10 tasks with a short answer). This simple tasks checking the assimilation of the most important physical concepts, models, phenomena and laws.

Tasks of an advanced level are distributed between the first and second parts of the examination paper: 5 tasks with a short answer in part 1, 3 tasks with a short answer and 1 task with a detailed answer in part 2. These tasks are aimed at testing the ability to use the concepts and laws of physics to apply one -two laws (formulas) on any of the topics school course physics.

The four tasks of part 2 are tasks high level complexity and test the ability to use the laws and theories of physics in a changed or new situation. The fulfillment of such tasks requires the application of knowledge from two or three branches of physics at once, i.e., a high level of training.

Task difficulty levels

Grading system

The task with the choice and recording of the number of the correct answer is considered completed if the number of the answer recorded in form No. 1 matches the correct answer. Each of these tasks is worth 1 point.

A task with a short answer is considered completed if the answer recorded in form No. 1 matches the correct answer.

Assignments 3–5, 10, 15, 16, 21 of Part 1 and Assignments 25–27 of Part 2 are worth 1 point.

Items 6, 7, 11, 12, 17, 18, 22 and 24 of Part 1 are worth 2 points if both elements of the answer are correct; 1 point if an error was made in specifying one of the elements of the answer, and 0 points if two errors were made.

Answers to tasks with the choice and recording of the number of the correct answer and a short answer are processed automatically after scanning the answer forms No. 1.

A task with a detailed answer is evaluated by two experts taking into account the correctness and completeness of the answer. The maximum initial score for tasks with a detailed answer is 3 points. For each task, detailed instructions for experts are provided, which indicate what each point is set for - from zero to the maximum score. IN examination version Before each type of task, an instruction is offered, which contains General requirements to format responses.

Exam duration and equipment

To complete the entire examination work is given 235 minutes. Estimated time to complete the tasks of various parts of the work is:

for each task with a choice of answers - 2-5 minutes;
for each task with a short answer - 3-5 minutes;
for each task with a detailed answer - from 15 to 25 minutes.

The number of participants in the USE in physics in 2018 (main day) was 150,650 people, including 99.1% of graduates of the current year. The number of participants in the exam is comparable to the previous year (155,281 people), but lower than the number in 2016 (167,472 people). In percentage terms, the number of participants in the USE in physics amounted to 23% of the total number of graduates, which is slightly lower than last year. A slight decrease in the number of students taking the USE in physics may be due to an increase in universities that accept informatics as an entrance test.

The largest number of USE participants in physics is noted in Moscow (10,668), the Moscow Region (6,546), St. Petersburg (5,652), the Republic of Bashkortostan (5,271) and the Krasnodar Territory (5,060).

The average USE score in physics in 2018 was 53.22, which is comparable to last year's score (53.16 test scores). The maximum test score was scored by 269 exam participants from 44 constituent entities of the Russian Federation, in the previous year there were 278 people with 100 points. The minimum USE score in physics in 2018, as in 2017, was 36 tb, but in primary scores it was 11 points, compared to 9 primary points in the previous year. The proportion of exam participants who did not pass the minimum score in 2018 was 5.9%, which is slightly higher than those who did not reach the minimum score in 2017 (3.79%).

Compared to the previous two years, the proportion of poorly trained participants slightly increased (21-40 tb). The share of high-scorers (61-100 TB) increased, reaching the maximum values for three years. This allows us to talk about the strengthening of differentiation in the training of graduates and the growth in the quality of training of students studying the profile course of physics.

In 2018, the proportion of exam participants who scored 81-100 points was 5.61%, which is higher than in 2017 (4.94%). For the USE in physics, the range from 61 to 100 test scores is significant, which demonstrates the readiness of graduates to successfully continue their education in universities. This year, this group of graduates increased compared to the previous year and amounted to 24.22%.
