This textbook is a collection of tasks to prepare for the Unified State Exam (USE) in chemistry, which is like a final exam for the course high school as well as university entrance exams. The structure of the manual reflects modern requirements for the procedure passing the 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 options for tasks, which in form and content are close to USE demos and do not go beyond the content of the course of chemistry, normatively determined by the Federal component state standard general education. Chemistry (Order of the Ministry of Education No. 1089 dated March 5, 2004).
Content Presentation Level educational material in tasks it is correlated with the requirements of the state standard for the preparation of graduates of a secondary (complete) school in chemistry.
Three types of tasks are used in the control measuring materials of the Unified State Exam:
- tasks basic level Difficulties with short answers
- tasks of an increased level of complexity with a short answer,
- tasks high level Difficulties with a detailed answer.
Each option examination work built according to a single plan. The work consists of two parts, including a total of 34 tasks. Part 1 contains 29 short answer items, including 20 basic difficulty items and 9 advanced difficulty items. Part 2 contains 5 tasks of a high level of complexity, with a detailed answer (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 at the entrance exams to universities.

The manual brought to your attention is intended for studying, summarizing and systematizing the material on chemistry studied at the senior level of the school. Working with the manual will also allow you to successfully prepare for the unified state exam (USE) in chemistry, which is carried out using control measuring materials (CMM) - standardized tasks, the content of which fully complies with the current regulatory framework for school chemistry education - the Federal State Educational Standard for Secondary ( complete) general education.
The allowance includes:
- educational and training materials on the main sections of the chemistry course (theory and training tasks);
- exemplary options USE;
- answers to tasks for independent work and tasks of approximate options.
Educational and training materials for the main sections of the chemistry course are a systematic presentation of the material about substances, their composition, structure and properties; about a chemical reaction, the essence and patterns of reactions of various types; about the use of substances and chemical transformations, methods of knowledge of chemical objects. The material included in the manual is a mandatory component (invariant core) of the content of all existing secondary school programs in chemistry for classes studying chemistry at the profile level.

Oksana Galkevich: Yura, you so quickly "rejected" Timur Urazbakhtin, and I wanted to ask him if he liked chemistry at school. Okay, I'll ask you. How are you?

Yuri Kovalenko:I loved it, it's one of my favorite items, actually.

Oksana Galkevich: Loved, right? Organic, inorganic?

Yuri Kovalenko:Organic, I'm for naturalness.

Oksana Galkevich: Come on, now you will take the rap for all of Russian journalism. Dear friends, this is our rubric "About the exam subject." Today we will talk about the unified state exam in chemistry. We will talk about how the exam goes, give some recommendations - not us, of course, but our guests, experts in the studio - how to prepare for the exam better, and tell you about some criteria for assessing student knowledge.

Yuri Kovalenko:A specialist from the Federal Institute for Pedagogical Measurements will give advice on what you can take for the exam, what to use on it and how to independently assess your knowledge, where you can test it. Let's figure it out then.

Oksana Galkevich: But first, perhaps, we will give a reference on the exam, namely on the Unified State Examination in chemistry. The fact is that you all know, dear friends, that there are mandatory exams, and there are elective exams. So chemistry is an elective subject. An assessment in this subject is required for admission to the chemical, chemical-technological, medical, biological faculties, as well as for admission to specialties that are associated with the organization Catering such as construction, light industry. Therefore, this exam is now very popular, how popular, literally in a second or two, we will find out from our guests. Last year, about 74 thousand people passed it in our country. To successfully pass the exam, you need to score 36 test points, but last year, unfortunately, 15% of those who took the exam could not overcome this bar. Wherein GPA on the exam was equal to 55 points.

Yuri Kovalenko:The exam lasts 3.5 hours, during this time it is necessary to complete several tasks, which, in fact, will be discussed now.

And today we are talking with our guests: in our studio Dmitry Dobrotin, head of the Federal Commission for the Development of the KIM Unified State Examination and the Unified State Examination in Chemistry, and Anna Kostromina, chemistry teacher at Moscow School No. 1028. Hello.

Oksana Galkevich: Hello, dear guests, Dmitry Yurievich, Anna Ivanovna.

Anna Kostromina: Hello.

Dmitry Dobrotin: Hello.

Oksana Galkevich: Dear viewer, please join our conversation. If suddenly you are a young man and are now studying in grades 9-11 - in advance, because the guys choose their profession, specialty - please call us, ask questions, because we have a person in the studio who is directly involved in the preparation of these very USE test tasks in chemistry, dear friends. If you are a teacher, please call and chat with Anna Ivanovna, who will tell you how to properly prepare children for the exam. If you are a parent and also empathize, also call and ask us something too. Dear friends, write, call us, send your messages to the SMS portal - 3443, the first letters "OTR".

Please tell us, we said that now this is a very popular, widespread exam, 74,000 took it just last year. What is the increase compared to 2016-2015? - what is the dynamics?

Dmitry Dobrotin: To be honest, there is practically no dynamics. That is, we have a stable contingent of those who choose our exam. That is, for the last...

Oksana Galkevich: Difficult exam, really.

Dmitry Dobrotin: Yes, including, probably, because of its complexity, probably because of its specificity and, nevertheless, rather high requirements. Here is the figure that you mentioned, 15% still do not overcome this bar, it just reflects that there is something for us to think about, which means that there is something to think about when preparing and systematically build preparation for the exam.

Yuri Kovalenko:But is the school curriculum enough to prepare for the exam in chemistry, or is it still necessary to take a tutor? Because 15% already say that every 7th person cannot pass this exam.

Oksana Galkevich: And "few hours" - you mean a regular school ...

Anna Kostromina: Yes, this is the baseline.

Oksana Galkevich: And more is specialized, in-depth study, Yes?

Anna Kostromina: Yes, profile level.

Oksana Galkevich: Do you teach in such a school, in such a class, or are you still in a regular general education school?

Anna Kostromina: I have a basic level of teaching chemistry and a specialized level of teaching chemistry in grades 10-11.

Oksana Galkevich: And that's how the guys who choose this subject to pass as a unified state exam ... You just give them some Additional tasks? Do you organize them around you for some extra work, do you stay after school? How do you build this interaction that Dmitry Yuryevich is talking about?

Anna Kostromina: There is a program according to which we teach, we have codifiers, specifications that allow us to prepare children for the unified state exam. But all the training is built just the same not to prepare the child specifically to solve test tasks, but to teach the child to think. Because if even the slightest change in wording has occurred in KIM, the child will be confused if we do not teach him to think. Therefore, first of all, we teach to think, to reason logically.

Yuri Kovalenko:That is, formulas alone are not enough, some kind of creativity and spatial thinking to understand how it all..?

Anna Kostromina: No, formulas alone were never enough.

Dmitry Dobrotin: I just want to add here that, of course, the more options for tasks in general, not only in test form- OGE, USE - and the more diverse, the more the child trains, the more calmly he goes to the exam. Therefore, this training, of course, should not be built only in the direction of tasks that will be included in the control and measuring materials. That is, here the variability in terms of tasks and in terms of the level of these tasks, of course, shows the child himself that he can, he copes, and at the stage of writing the version directly, this, of course, gives him confidence and calmness, and this is very important in the exam.

Oksana Galkevich: Dmitry Yuryevich, you, as a person who, in fact, is involved in the formulation of these same tasks, do you try to be more intricate somehow, more complicated, or vice versa, nothing more to make it clear?

Dmitry Dobrotin: You know, it depends on the form of the task. Because there are tasks that should directly lead the child to a very specific answer, despite the fact that, of course, he must think. That is, we have practically no assignments for the reproduction "you know or you don't know", that is, all the same, some kind of process of reflection is assumed. There are tasks that lead the child to the need to build some kind of logical chains, cause-and-effect relationships; there are tasks that involve the creation of some kind of model experiment, when, according to the condition of the task, the child must reproduce in his figurative thinking those processes that occur with substances, how they change in the course of chemical reactions. Therefore, the creation of images and work, perhaps, on the formation of images ... Teachers, of course, do this, including, of course, this should be facilitated by a chemical experiment, which still distinguishes our course from many others in many ways.

Oksana Galkevich: Let's talk about the experiment again. Let's listen to our viewer Tatyana from Nizhny Tagil. Tatyana, hello.

Viewer: Hello.

Oksana Galkevich: Hello. Are you a mom or a teacher?

Viewer:I am the mother of the one who passed the exam in chemistry in the 11th grade last year, and the teacher too, but not in chemistry. I would like to ask a question to those who create these USE tests: why do they have a basic textbook, it says so, and there is only one lesson a week, what kind of experiments can you talk about in it? Why do they want more from them? Of course, at our own expense, so to speak, we went through everything that ...

Oksana Galkevich: With tutors, that is, right?

Viewer:…outside of the textbook and, of course, solving problems is much more difficult than in the textbook.

Oksana Galkevich: Yes, thank you, Tatyana. This is probably a question for you too.

Anna Kostromina: This is exactly what I was talking about. If you have already decided in advance that the child is going to enter a university where an exam in chemistry is required, then after grade 9 you need to clearly decide that you need to study chemistry at a specialized or advanced level. Because, of course, the basic level will not give us that opportunity, that large amount of information that the child needs, and all this falls additionally on the shoulders of the child. That is, the child will have to learn more information on his own, show more independence. Although, again, the teacher is nearby, the teacher can direct, give certain tasks and check.

Oksana Galkevich: Is the teacher ready? You got one, you know, very inquisitive, but without a tutor, and now he constantly pesters with questions: "Give me a task." Educator, are your colleagues now ready to pay attention to such meticulous things?

Anna Kostromina: I think yes. Such children are always very interesting, very interesting.

Oksana Galkevich: You know, as if it's happiness. Actually, I think yes, it is...

Anna Kostromina: For a teacher, it is happiness when such children.

Yuri Kovalenko:Interest in the eyes of the student.

But still, which of the tasks are considered obviously easy, and which ones most often fail in the exam?

Anna Kostromina: Calculation problems are quite complex. This is traditionally difficult, because they include not only our chemical science, but also a mathematical component, you can’t get away from this.

Yuri Kovalenko:That is, if it is bad with mathematics, it will also be a problem with chemistry?

Anna Kostromina: Well, I can’t say that children who pass chemistry have problems with mathematics, but sometimes there are incidents of a calculated plan. That is, you need a combination of all this. Therefore, as a rule, it is more difficult for children, and it is precisely the calculation tasks that are given.

Yuri Kovalenko: Is it easier?

Anna Kostromina: And it’s easier - this is our first part, the traditional one, where even a basic level of knowledge is enough if the child works independently.

Yuri Kovalenko:Well, for example, some question from the first part.

Anna Kostromina: I think that the easiest questions for children are on the periodic table of chemical elements.

Oksana Galkevich: Woo, it seems to me that even Yura and I are now ...

Yuri Kovalenko:Is it "Name the 48th element" or what?

Anna Kostromina: No, why? The elements are given, that is, the elements are listed, and they need to be arranged in a certain sequence.

Dmitry Dobrotin: For example, in ascending order of atomic radii.

Anna Kostromina: Yes.

Dmitry Dobrotin: Quite easily, children cope with classification tasks, for classification - this is the establishment of a correspondence between the formula of a substance and the class, the group to which it belongs, children quite successfully cope with this. Probably, this is also because they begin to work out these assignments at the stage - just what Anna Ivanovna was talking about - 8-9th grades, then it only improves. And there is some material that grows already in the 10th-11th grades, including organics, for example, organic chemistry begins in the 10th grade. Of course, questions in this respect, in this section, also often cause, perhaps, a little more difficulty; perhaps this is due to the specifics of writing the formulas of organic substances, which are often written in expanded form, and for children with, perhaps, underdeveloped figurative thinking this causes additional difficulties. Therefore, such difficulties also occur in this regard.

Oksana Galkevich: Two calls in line, can we get it?

Dmitry Dobrotin: We accept, of course.

Oksana Galkevich: Tatyana is also from Petersburg, hello.

Viewer:I am from St. Petersburg, Ekaterina Yurievna.

Oksana Galkevich: Hello, I'm sorry, I was told wrong.

Viewer: Hello.

Oksana Galkevich: We listen to you.

Viewer:I myself graduated from the Herzen Institute with a degree in Chemistry, but, unfortunately, I could not work at school, but both of my sons passed the Unified State Examination by the will of my mother. And you know, I want to say that actually...

I agree with Anna Ivanovna that it is logic in chemistry that is very important, that is, in fact, there are a lot of tasks in the exam that are associated with exceptions to the general rules. In fact, the children really do not know them and perhaps should not know them. Maybe pay more attention to the logic of chemistry? In fact, it is a pity that the textbooks of Rudzitis and Feldman left the program, in fact, they are now studying mainly according to Gabrielyan, there is very ... Chemical logic is not always sustained there. Therefore, it seems to me that it is also worth paying attention to in schools when preparing for the Unified State Exam and the OGE, so that they return to the classics. Thank you.

Oksana Galkevich: Thank you. Qualified opinion, authoritative opinion, experience of your colleague.

Dmitry Dobrotin: Yes.

Anna Kostromina: Yes, more than.

Dmitry Dobrotin: Probably, we can partly agree that textbooks play a really big role, and how logically the textbook material itself is presented and how much the teacher manages to form these logical skills, and, again, not only on assignments, but also on questions that involve full detailed answers. That is, again, this ability of a child to formulate fully and extensively, it seems to me, is very important skill, but when a child also speaks a scientific language using chemical terminology, this also develops his thinking very well. That's why…

As for the quality of textbooks, there are certain problems. But what should be said here? How many people, so many opinions. Because I know that, for example, there is a fairly large group of teachers who are sympathetic to the textbook by Oleg Sergeevich Gabrielyan, at the same time, for example, they have complaints about the textbook of other authors who were named Rudzitis, Feldman.

Oksana Galkevich: By the way, let's ask our directors to show the FIPI website, which, dear friends, has open bank tasks of the unified state exam for previous years. So you open the FIPI page, find this open bank of tasks, click, now it will open for me, select here the subject that you intend to prepare for unified state exam(in this case, today we have chemistry) - it opens here, look: " Theoretical basis Chemistry", "Inorganic Chemistry", "Organic Chemistry" ...

Dmitry Dobrotin: Main sections.

Oksana Galkevich: Sections, yes. I’m even scared to look into the organic one, what questions are there.

I wanted to ask Anna Ivanovna: tell me, is this, in principle, a good method of preparing for the unified state exam - just solving tasks for previous years?

Anna Kostromina: Yes, it's very convenient.

Oksana Galkevich: Very comfortably.

Anna Kostromina: And the kids are comfortable.

Oksana Galkevich: That is, it can be done anywhere in our country? Not everyone has the opportunity, maybe with tutors to study additionally. If a person, so to speak, is set on some task, on winning, on the decision to improve himself in chemistry, it’s not bad to prepare for the exam, maybe even to enter ...

Dmitry Dobrotin: Yes of course. So you need to expect that you will definitely do it. And here the bank is still, you know, as one of the components of preparation. That is, if you only focus on the tasks of the bank, then I absolutely agree with Anna Ivanovna that there is a situation that the variability of these tasks can be confusing, that “I solved these tasks, I met a little different”, the child begins to get lost. Therefore, here it is necessary to solve more diverse tasks and at some stage move on to solving options in order to understand how to plan time for solving, maybe even in what order to solve which parts.

Oksana Galkevich: That's how? Tell in what order to solve which parts. Where should you start? - probably from the simplest?

Dmitry Dobrotin: Yes. In general, psychologists recommend really going from simple to complex, and if the task causes some very serious difficulties, skip it and move on. I know a fairly large number of graduate children who start with the more difficult part, because there you have to write down everything in detail, so you immediately plunge into the world of signs and images, and then, as if activating your brain, you you move on to those tasks that involve more, let's say, the possibility of choosing from the proposed options, the possibility of relying on the left formulas.

Anna Kostromina: More simple steps.

Dmitry Dobrotin: Yes, simpler steps.

Anna Kostromina: How many children, so many methods will be.

Oksana Galkevich: You don't insist, you never say that "That's just how to do it, start with the simple and move on to the complex?"

Anna Kostromina: And there is no point. A child cannot be broken, he must think over how he will do it ...

Oksana Galkevich: You rarely hear this from our teacher.

Anna Kostromina: Our job is to guide, that is, to offer options, so try and try so, the child must choose. That is, I believe that it is very important that the child chooses.

Yuri Kovalenko:Are there any tricks in the exam? Still, chemistry is so enough practical subject. Is there any practical experience during the exam, or is it out of the question?

Dmitry Dobrotin: It is the conduct of experiments in the Unified State Examination that is not supposed, in the OGE there is a model that involves the conduct of an experiment. If we are talking about the Unified State Examination, then nevertheless there are tasks, the performance of which is very accurately based on the ability to conduct an experiment and on knowledge, for example, of the signs of chemical reactions.

Yuri Kovalenko:That is some kind of qualitative reaction.

Dmitry Dobrotin: There are definitely at least 3-4 such tasks in the unified state exam, so the experimental component plays an important role.

Oksana Galkevich: Irina from Moscow, hello.

Viewer:Hello. Here I am also a mother, we are preparing for the second time already to pass the exam. My eldest child already passed the exam, we passed it very successfully and entered all universities. But now I would like such a wish for the compilers of the USE programs. We have now adopted the federal educational state standard in education and textbooks, and I would like all these programs that are compiled for the Unified State Examination to be within the federal educational state standard so as not to load the child with classes with tutors. Because no matter how secret it is for anyone: in order to successfully pass the exam, you need to study with a tutor, but this places a big burden on the child. Of course, we manage to do everything, we pass everything, we do it, but how would you think: the child is studying, grade 11 is basically 7 lessons, and can you imagine, after 7 lessons he still runs somewhere to the tutors. This is almost every day, because we have to pass 4 exams, we are preparing for 4 subjects. We passed everything successfully, but it was a very big burden for the child.

Oksana Galkevich: And for parents too, yes.

Viewer:I would like all these compiling the exam were within the school curriculum, this is my wish as a mother, who, as it were, saw all this.

Oksana Galkevich: Yes, Irina, thank you very much. There are a lot of messages, by the way, on our SMS portal - they ask why organic questions are from the profile. “Why are there mistakes in the USE?” Belgorod Region writes to us (I don’t know what this opinion is based on). "Why are the tasks of the open segment of the FIPI not systematized by the chemistry of the elements and there are no answers?" Asks the Volgograd region. If possible, very briefly.

Dmitry Dobrotin: In principle, the answers should be there, because this is really a training bank. As for the level of requirements, you still need to clearly understand: there is a basic one and there is an advanced one, and the tasks of the unified state exam are drawn up precisely at two levels, at the basic and advanced ones, so the advanced level, of course, is focused not on an hour-long study, but on study over a large amount of time.

Oksana Galkevich: Anna Ivanovna, are your colleagues asking whether Khomchenko's textbook is now allowed to study the subject of chemistry?

Dmitry Dobrotin: This is a guide for university applicants.

Anna Kostromina: This is not a textbook, this is a guide.

Dmitry Dobrotin: As such, there is no such textbook.

Anna Kostromina: It's like an add-on for those who want it.

Oksana Galkevich: Thank you, dear friends, thank you to our experts. To everyone who is preparing for the chemistry exam, we wish good luck, dear friends.

Yuri Kovalenko:Not fluff or feathers, to be exact.

Oksana Galkevich: Are there many 100 points, by the way?

Dmitry Dobrotin: 0.49% is quite a lot. 0.5% is a good indicator, one of the highest in the subjects to be handed over.

Oksana Galkevich: Very good. I wish you 1% 100 points in the exam this year.

Dmitry Dobrotin: Thank you.

Anna Kostromina: Thank you.

Oksana Galkevich: In our studio today, dear friends, were Dmitry Yuryevich Dobrotin, head of the Federal Commission for Developers of Control and Measurement Materials for the Unified State Examination and the Unified State Examination, and Anna Ivanovna Kostromina, chemistry teacher at Moscow School No. 1028. Thanks a lot.

Yuri Kovalenko: Thank you.

Oksana Galkevich: And we do not say goodbye to you, we will return in a few minutes.

Dmitry Dobrotin: Thank you.

Anna Kostromina: Thank you.
