1. Purpose of KIM Unified State Exam

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

The Unified State Examination is conducted in accordance with Federal law dated December 29, 2012 No. 273-FZ “On education in the Russian Federation.”

Control measuring materials make it possible to establish the level of mastery by graduates of the Federal component of the state standard of secondary (complete) general education in chemistry, basic and specialized levels.

The results of the unified state exam in chemistry are recognized educational organizations secondary vocational education and educational organizations of higher professional education as the results of entrance tests in chemistry.

2. Documents defining the content of the Unified State Exam KIM

3. Approaches to selecting content and developing the structure of the Unified State Exam KIM

The basis of the approaches to the development of the KIM Unified State Exam 2017 in chemistry were those general methodological guidelines, which were determined during the formation of examination models of previous years. The essence of these settings is as follows.

• KIMs are focused on testing the assimilation of a knowledge system, which is considered as an invariant core of the content of existing chemistry programs for general education organizations. In the standard, this knowledge system is presented in the form of requirements for the training of graduates. These requirements correspond to the level of presentation of the tested content elements in the CMM.
• In order to ensure the possibility of differentiated assessment of the educational achievements of KIM Unified State Examination graduates, the mastery of basic educational programs in chemistry is checked at three levels of complexity: basic, advanced and high. The educational material on which the assignments are based is selected on the basis of its significance for the general education training of graduates high school.
• Completing the tasks of the examination work involves the implementation of a certain set of actions. Among them, the most indicative are, for example, such as: identifying classification characteristics of substances and reactions; determine the oxidation state chemical elements according to the formulas of their compounds; explain the essence of a particular process, the relationship between the composition, structure and properties of substances. The ability of the examinee to carry out various actions when performing work is considered as an indicator of assimilation of the studied material with the necessary depth of understanding.
• The equivalence of all versions of the examination work is ensured by maintaining the same ratio of the number of tasks that test the mastery of the basic elements of the content of key sections of the chemistry course.

4. Structure of KIM Unified State Exam

Each version of the examination paper is built according to a single plan: the paper consists of two parts, including 40 tasks. Part 1 contains 35 short answer questions, including 26 questions basic level complexity (serial numbers of these tasks: 1, 2, 3, 4, ...26) and 9 tasks of an increased level of complexity (serial numbers of these tasks: 27, 28, 29, ...35).

Part 2 contains 5 tasks high level complexity, with a detailed answer (serial numbers of these tasks: 36, 37, 38, 39, 40).

Tips for preparing for the Unified State Exam in chemistry on the website website

How to competently pass the Unified State Exam (and Unified State Exam) in chemistry? If you only have 2 months and you’re not ready yet? And don’t be friends with chemistry...

It offers tests with answers for each topic and task, by passing which you can study the basic principles, patterns and theory found in the Unified State Exam in chemistry. Our tests allow you to find answers to most questions encountered in the Unified State Exam in chemistry, and our tests allow you to consolidate the material, find weak points, and work on the material.

All you need is the Internet, stationery, time and a website. It is best to have a separate notebook for formulas/solutions/notes and a dictionary of trivial names of compounds.

1. From the very beginning, you need to assess your current level and the number of points you need, for this it is worth going through. If everything is very bad and you need excellent performance, congratulations, even now all is not lost. You can train yourself to pass successfully without the help of a tutor.
   Decide on the minimum number of points you want to score, this will allow you to understand how many tasks you must solve accurately to get the score you need.
   Naturally, take into account that everything may not go so smoothly and solve it as best you can. larger number tasks, or better yet, everything. The minimum that you have determined for yourself - you must decide ideally.
2. Let's move on to the practical part - training for the solution.
   Most effective method- next. Select only the exam you are interested in and solve the corresponding test. About 20 solved tasks guarantee that you will meet all types of problems. As soon as you begin to feel that you know how to solve every task you see from beginning to end, proceed to the next task. If you don’t know how to solve a task, use the search on our website. There is almost always a solution on our website, otherwise just write to the tutor by clicking on the icon in the lower left corner - it’s free.
3. At the same time, we repeat the third point for everyone on our website, starting with.
4. When the first part is given to you at least at an average level, you begin to decide. If one of the tasks is difficult, and you made a mistake in completing it, then return to the tests on this task or the corresponding topic with tests.
5. Part 2. If you have a tutor, focus on studying this part with him. (provided that you are able to solve the rest at least 70%). If you started part 2, then you should score a passing grade without any problems 100% of the time. If this does not happen, it is better to stay on the first part for now. When you are ready for part 2, we recommend that you get a separate notebook where you will write down only the solutions to part 2. The key to success is solving as many tasks as possible, just like in part 1.

IN KIMakh Unified State Examination The following changes will be made in 2017:

1. The approach to structuring part 1 of the examination paper will be fundamentally changed. It is expected that, unlike the examination model of previous years, the structure of Part 1 of the work will include several thematic blocks, each of which will present tasks of both basic and advanced levels of complexity. Within each thematic block, tasks will be arranged in increasing order of the number of actions required to complete them. Thus, the structure of Part 1 of the examination paper will be more consistent with the structure of the chemistry course itself. This structuring of Part 1 of KIM will help examinees during work to more effectively concentrate their attention on the use of what knowledge, concepts and laws of chemistry and in what relationship the completion of tasks that test mastery will require educational material a certain section of the chemistry course.

2. There will be noticeable changes in approaches to designing tasks at a basic level of complexity. These can be tasks with a single context, with the choice of two correct answers out of five, three out of six, tasks “to establish correspondence between the positions of two sets,” as well as calculation tasks.

3. Increasing the differentiating ability of tasks makes it objective to raise the question of reducing the total number of tasks in the examination paper. It is expected that the total number of exam tasks will be reduced from 40 to 34. This will be done mainly by streamlining the optimal number of those tasks, the implementation of which involved the use of similar types of activities. An example of such tasks, in particular, are tasks focused on verification chemical properties salts, acids, bases, conditions for ion exchange reactions.

4. A change in the format of tasks and their number will inevitably be associated with an adjustment in the grading scale for some tasks, which, in turn, will cause a change in the primary total score for completing the work as a whole, presumably in the range from 58 to 60 (instead of the previous 64 points).

The consequence of the planned changes in the examination model as a whole should be an increase in the objectivity of testing the formation of a number of subject and meta-subject skills, which are important indicator success in mastering the subject. We are talking, in particular, about such skills as: applying knowledge in the system, combining knowledge about chemical processes with an understanding of the mathematical relationship between various physical quantities, independently assess the correctness of the implementation of educational and educational-practical tasks, etc.

This textbook is a collection of tasks for preparing for the Unified State Exam (USE) in chemistry, which is both a final exam for a high school course and an entrance exam to a university. The structure of the manual reflects modern requirements for the procedure passing the Unified State Exam in chemistry, which will allow you to better prepare for new forms of final certification and for admission to universities.
The manual consists of 10 variants of tasks, which in form and content are close to the demo version of the Unified State Exam and do not go beyond the content of the chemistry course, normatively determined by the Federal component of the state standard of general education. Chemistry (Order of the Ministry of Education No. 1089 of 03/05/2004).
The level of presentation of the content of educational material in tasks is correlated with the requirements of the state standard for the preparation of secondary (full) school graduates in chemistry.
The control measurement materials of the Unified State Exam use tasks of three types:
- tasks of a basic level of difficulty with a short answer,
- tasks of an increased level of complexity with a short answer,
- tasks of a high level of complexity with a detailed answer.
Each version of the examination paper is built according to a single plan. The work consists of two parts, including a total of 34 tasks. Part 1 contains 29 short answer questions, including 20 basic level tasks and 9 advanced level tasks. Part 2 contains 5 tasks of a high level of complexity, with detailed answers (tasks numbered 30-34).
In tasks of a high level of complexity, the text of the solution is written on a special form. Tasks of this type make up the bulk of the written work in chemistry in university entrance exams.
