It is shown that in the Unified State Exam, the standardized evaluation system for tasks requiring detailed responses makes teachers consider the only solution to be correct – the one specified by the developers of the test. The author proposes to modify the criteria of evaluation for tasks requiring detailed responses. The author offers an example of solving calculation problems.

The article describes an innovative approach to organization of educational process based on the «flipped classroom» technology. The experience of teaching the course of organic chemistry in the gymnasium №9 in Voronezh (O.S.Gabrielyan’s program, 10th Grade) using the described technology is presented. The paper focuses on specifics of model implementation and benefits of «flipped classroom», its resource and methodological support.

A scenario for the lesson "Initial Chemical Concepts" is offered. It is a lesson of revising the acquired knowledge and developing abilities of its application. “Visiting” the virtual museum “Chemistry for protecting the Homeland” students perform the tasks offered by the teacher.

The lesson on "Sulfur as an elemental substance and chemical element" is a research lesson designed with the use of the author’s technique.

The paper presents the application of the author's quest-technology (search technology) for the organization of the chemistry olympiad for groups of primary school children and their parents within the educational project «Family Chemistry». It is shown that the use of group work for solving olympiad tasks at the stage of early learning of chemistry has a special competitive nature, the level of which is significantly higher than that for individual participation in the olympiad. The combination of practical and theoretical material of tasks enhances pupils’ motivation for participating in the competition.

The relevance of addressing issues of health and health protection in the chemistry course in high school is discussed in the article. The author analyzes normative documents, determining the content of chemical education in the framework of the problem mentioned above. The methodological possibilities of formation of students’ knowledge about health and health care in the study of chemistry in grades 10-11 are described. The examples of tasks aimed at checking the assimilation of this knowledge are offered.

The success of students from South-East Asia at various international Olympiads in science and technology, as well as results of the TIMSS and PISA tests requires studying the region system of science education. Analysis of the state of science education in the countries such as China, South Korea and Singapore shows the relevance and feasibility of the competence-based approach to learning at all stages of the educational process. To ensure the competence approach to training a methodical system of tasks and exercises should be developed, that would allow one to carry out the formation of universal educational activities of secondary school students.

The article deals with issues related to the formation of the content of teaching material and requirements. The authors give general and substantive functions that are required in the design of the content of the subject “Chemistry”. The paper provides examples of the use of information on selection criteria developed by leading educators. In addition, the recommendations for the formation of the chemical content of school education on the basis of didactic units are offered.

This article lists the most interesting excursions and lectures for schoolchildren and teachers of chemistry, conducted by the Moscow universities and research institutions in accordance with the innovative program of the Moscow chemical society named after D. I. Mendeleev on the instruction of schoolchildren in chemistry and ecology. There are themes of lectures, talks and master classes, which caused great interest among students and teachers of chemistry not only in Moscow but also in other cities.

The article presents data on the properties and other characteristics of the chemical elements from silver to xenon, most clearly distinguished from all others.

The authors provide recommendations for the experiment at home.

Egg-shell is used in folk medicine as an additional source of calcium. Employing methods of volumetric analysis to egg-shell the following data about its chemical composition are received: carbon oxide (IV) – 42, 3%, calcium oxide – 52, 4% (CaCO3 – 93, 6%; Ca – 37, 4%) and magnesium oxide – 1, 4% (MgCO3 – 2, 9%; Mg – 0, 84%). Egg-shell aqueous solution has is weakly alkaline.

The history of research of thermochemistry processes involving organic compounds in our country at the turn of the XX century has been considered. Research in this field was carried out in the thermo-chemical laboratory of the Moscow University founded by V. F. Luginin. Research by V. F. Luginin, V. А. Sventosslavskii, I. A. Kablukov played an important role in the development of this sphere of chemical knowledge.

The activities described are aimed at forming steady interest in disciplines of a natural-science cycle, such as chemistry and biology which can be implemented not only in the class, but also through out-of-class activities, additional courses, games. Such out-of-class activity stirs up cognitive activity of students, systematizes the students’ knowledge in the field of chemistry and biology; proves the practical importance of chemistry and biology, knowledge of laws and regularities in human life, cultivates independence in acquisition of new knowledge. It broadens horizons, an independent way of thinking, erudition that will help students in their future professional activity. The author offers not only interesting tasks developing cognitive interest but also the description of fascinating experiments.
