Among the tasks with the parameters included in the profile USE in mathematics, a special class of tasks can be distinguished, which are almost impossible to solve with standard school methods. Often, the functions on the left and right sides of the equation have a fundamentally different nature, which does not allow the use of an analytical approach. And the complex form of these expressions makes plotting problematic. The way out in this situation can be a minimax method for solving problems with parameters, which relies on the use of monotonicity and boundedness of functions.
Some lessons may seem boring to children. And then discipline begins to suffer in the classroom, students quickly get tired and do not want to take part in the discussion. Case-lessons were created to connect school learning knowledge with urgently needed competencies, such as creativity, systemic and critical thinking, purposefulness, and others. Thanks to the cases, you can help the student to benefit and enjoy learning, to cope with his personal problems!

Analysis of the trial exam in biology in grade 11 in the USE format.
Teacher: Kravchina E.P.
In order to control the preparation of graduates of the 11th grade of the educational institution for the Unified State Examination in subjects of choice, to familiarize them with the content of KIM, to control the state of teaching subjects and in accordance with the schedule of activities for the preparation and conduct of the Unified State Examination in the 2017-2018 academic year, December 26, 2017 a trial exam in biology in the USE format was held. The exam was conducted using uniform control measuring materials and subsequent processing of the results. 2 people took part in the trial exam in biology. One student was absent due to illness.
Violations in filling out the response forms were not recorded.
Analysis of the results shows that students have a good command of such topics.
Task difficulty levels: B - basic, P - advanced, C - high

Graduates showed stable knowledge and skills in solving the basic and advanced levels of complexity, tasks of part 1.
The most difficult questions were those that test the ability to work with text, diagrams, solve molecular and genetic problems of the task of part 2.
Based on the analysis of typical mistakes recommended:
1. Continue individual work with students to eliminate gaps in knowledge in preparation for the final certification in biology.
2. To ensure an individual approach to students in the process of preparing for the final certification, allowing the less prepared to work out the skills being formed for a longer time.
3. To develop in the lessons the skills related to extracting from the text and using the information necessary for practical application in everyday life.
4. Work with assignments for finding and correcting errors in the biological text, teaching correctly, formatting answers in similar assignments.
5. Pay more attention to solving genetic and molecular problems, learn how to arrange them in accordance with the requirements.
6. It is advisable to use tasks for control similar to the tasks of the examination work.
7. Conduct a trial USE exam in the subject with a 11th grade student Victoria Popova, who was absent due to illness.
The reference was prepared by a biology teacher: Kravchina E.P.

Based on the analysis of the results of the USE in biology and the performance of tasks, it can be concluded that the students did a good job with the tasks of the first part.
It should be noted a sufficient level of biological literacy and competence of students, possession of general biological and environmental patterns.
But incomplete answers to tasks with a free detailed answer, biological mistakes made, poor knowledge of algorithms for solving problems in genetics did not allow graduates to get the desired results.
Necessary areas of work :
1. Correction of work programs with the planning of more hours on the most complex topics and sections in biology.
2. Repetition of material on botany and zoology at a higher level in terms of ecology, evolution, genetics.Plan a repetition system, including, if possible, in the content of each lesson one or another skill listed in the codifier.
3. Implementation of interdisciplinary connections between geography, chemistry, biology, physics in the study of the vital processes of living organisms.
4. Advanced training for teachers of biology, according to the peculiarities of preparing students for the exam and evaluating answers.
Recommendations and suggestions:
1. Since the test part of the examination paper has undergone significant changes, it should be very carefully
study the Demo version of KIM USE 2017..
2. Use for knowledge control various test tasks based on the materials of the Unified State Examination of previous years, a demo version of 2017, tasks
StatGrad systems, etc. Actively use electronic and Internet resources, materials from the Open Bank of USE tasks.
3. Systematically conduct intra-school sections of students' knowledge and a trial exam in biology in the form of the Unified State Examination in the 11th grade. Based on the results of the diagnostics, analyze the work of students.
4. Pay special attention to the correctness of filling in the answer forms of the tasks presented in the new form.
5. Conduct individual classes in general biology and genetics.

The main wave of passing the unified state exams in 2018 begins. Graduates take compulsory exams and elective exams and look forward to their preliminary results. The results of the Unified State Examination in several subjects will be known after graduation parties at schools. When will they be known and how to find out the results of the USE in biology in 2018 according to passport data using the official website of the USE and the State Services portal.
The unified state exam in biology in 2018 is held on June 18, the results will be known no later than July 4. This date is the last, it is announced in advance and is standard for people who check the exam and publish the results.
In cases where the results are ready for publication earlier than the officially specified date, they are published ahead of schedule. That is why it makes sense for schoolchildren who are impatient about how they passed the exam, it makes sense to check the results two or three days before the specified date.
To find out the results of the USE in biology in 2018 according to passport data, you need to use either the official USE portal or the State Services portal. The page of the official portal of the exam -. In order to check the results of the exam, you need to enter your passport data, as well as the registration code or document number, which are indicated on the pass form for the exam. By choosing from the list the region in which the exam was taken, the eleventh grader can receive all the available information about the results of the exam even before it is announced at school.
A fallback option for familiarizing yourself with the results of the USE in biology in 2018 is on the State Services portal. The interface for receiving the service is almost identical, and the only thing that will be required additionally is registration on the State Services themselves. This option should be kept in mind in case the official USE website cannot withstand the load, especially during the publication of the results of popular exams.
We wish the graduates only positive emotions from the results of the Unified State Examination and successful admission to higher educational institutions. For those who failed the Unified State Examination, we remind you that retaking exams in compulsory subjects (basic mathematics and Russian) will be possible in July or September 2018. For all other subjects, retake will be possible only next year.
