The author reveals the content of the teacher's assessment activity in the conditions of implementation of the requirements of the Federal state educational standards. The article focuses on the diagnosis of metasubject educational results and functional literacy. Examples of assessment tools are provided.

The article is devoted to the problem of students completing homework in chemistry. The possibilities of the information environment for the formation of cognitive activity of students when doing homework in chemistry are shown on the example of the topic «Chemical elements of the VA group».

Having received training in general education subjects, students often find it difficult to use their knowledge when studying special subjects. Integrated classes promote students|’ activity, development their professional thinking, and provide an opportunity for the synthesis of knowledge. Integrated classes arouse interest in the subject, relieve tension, uncertainty, and help the conscious assimilation of the material. Integration not only enriches the content of one subject with the content of another, but also combines them and provides comprehensive training, forming general and professional competence, interdisciplinary results. The use of integrated learning technology in the process of training students of secondary vocational education is one of the areas that implements the main goal of professional education: training a highly qualified, competent specialist who is able to think broadly and unconventionally, ready for self-development, self-education and self-improvement. The aim of this article is to show a concrete example of the realization of the integrated approach in the system of professional education.

The authors present an integrated lesson (biology, geography, physics, chemistry) "Tell us about water" which is a one-task lesson with the use of photosets.

The main purpose of the lesson is to introduce students to the geometric structure of hydrocarbon molecules. During the lesson, the students create ball-and-stick and tetrahedral models of hydrocarbon molecules. The lesson demonstrates the need for geometric knowledge to understand the structure, and properties of substances.

The problem of the continuity of subject oriented chemistry education in the school-university subsystem is considered. A violation of the principle of continuity of differentiated general chemical training in the school-university subsystem is revealed. The necessity for studying chemistry in any profile of senior school is declared.

The article describes the production and use of polycrystalline silicon.

The article discusses approaches to completing the tasks of the second part of the exam in chemistry related to reactions involving organic compounds, as well as the deriving formulas of organic compounds.

The article focuses on the problem of training Chemistry teacher from the point of view of his bilingual communicative competence in the context of his professional education and future teaching career. Advantages of content and language integrated learning in English language classroom in baccalaureate groups of intended Chemistry teachers are discussed from the point of view of raising motivation to learning English and efficiency of mastering important notions of Chemistry. The authors present a sample framework of integrated English language and Chemistry classroom aimed at discussing a relevant chemical and ecological issue and developing communicative foreign language skills.

The article considers the titrimetric method of quantitative chemical analysis. The materials presented can be applied in both the organization of project and research activities of students and additional classes and elective courses for the preparation for chemistry olympiads.

The authors offer a description of an extracurricular laboratory class for the 10th grade students engaged in chemical research. The class includes introduction into the quantitative method of determining concentrations of acids and alkalis; practical determination of the molar concentration of hydrochloric acid and sodium hydroxide by titration. Conducting such classes contributes to the development of students’ experimental skills and their cognitive interest.

The material about the period of the First World War is presented in the article. The war demonstrated the empowerment of civilian technology for military purposes. The researchers subsequently noted the increasing intensity of the war, its industrialization. The country’s defense capability is beginning to depend on the ability of national industry to produce both ammunition and means of protection. The article presents brief characteristics of several toxicants and the history of creating means of protection, including the Zelinsky-Kummant gas mask.

The material of the quiz “The contribution of chemists to the Victory in the Great Patriotic War” for 8-11 classes is presented.

The article describes the purpose, objectives and procedure of the contest of Olympiad problems in chemistry “Original problem”, annually organized by the Tver regional branch of the Association of chemistry teachers of Russia. This competition is considered not only as a contest of professional skills of teachers, but also as an innovative form of organization of extracurricular activities of students. Participation of teachers in this competition contributes to their professional growth. Participation of students in it prepares them for independent development of final projects in chemistry in accordance with the requirements of the Federal state educational standards. Two examples of competitive Olympiad tasks are given.

The article discloses specific features of organizing students’ research of the chemical composition of the body of freshwater lunged snails, peculiarities of its seasonal dynamics and its dependence on environmental factors. Methods of determining glucose concentrations in hemolymph and glycogen in hepatopancreas are described.

The topicality of chemiluminescence studying based on the integrative approachas part of extracurricularpractice is substantiated in this paper. The principle of concept formation of the chemiluminescence is presented. The demonstration of obtaining singlet oxygen is described.
