Today we are not simply bystanders, but active participants of yet another crisis of the education content initiated by the social crisis of the late 80s. What will the outcome be: the catastrophe or the renewal – to the great extent it depends on us also. To make a forecast of its solution the author reveals immediate causes, having them formulated in the form of problems, demanding prior solving.

The concept «oxidation degree» is widely used at studying of ox-red reactions. However, it is frequent in textbooks in chemistry assumptions of impossibility using this concept in a course of organic chemistry, about fractional values oxidation degrees that conducts to problems with arrangement stoichiometric coefficient in the equations of ox-red reactions with participation of organic connections.

The article content is of interest to the subject teacher. It will help in preparation and execution of education.

The main purpose of the article is demonstration of mediaeducation’s opportunities for chemical lesson in the modern conditions of informatization. The author suggests using the Internet as an instructional tool for developing of critical thinking for classroom learning. The article represents author’s scheme of media-lesson on the base of strategies for critical thinking. There is an example of media-lesson which was made using the scheme

In the learning process it is necessary to establish conditions for students to develop cognitive activity and their self-actualization, to collect their own experience. With this purpose the authors organize students’ project activity.

The article describes the development of chemistry lesson for 9 class of school on "General characteristics of the elements of the VA group." The lesson is designed based on the ideas of prediction study and satisfy the requirements of the Federal state educational standard of basic and high education of the second generation. Special attention is paid to improve of one of the most important transdisciplinarity skills of students - information skills. As a mechanism that implements the method of development of information skills of students in chemistry classes, used taxonomy of educational tasks. The article also explained the meaning of the concepts of "anticipation", "information skills", "taxonomy".

A didactic game is the means to broaden, deepen, and consolidate skills and expertise. It allows implementing all leading learning functions: educative, disciplinary, and evolutive. The roundup lesson on the theme of “Metals” in the game mode is offered.

For students of chemical and biological classes we conduct a theoretical workshop, where from the chemical standpoint examine the food ingredients, energy of nutrition products, their digestion (splitting) in an organism and the role of ferments in these processes.

For those who are majoring in cook-confectioner specialty it is necessary to include the cluster of nanotechnology classes in the core chemistry course. Knowledge in the sphere of nanotechnology will help the future experts to become competitive the labor market.

The author offers a variant of a final test for the 9th Form students, which is comprised in accordance with the level differentiation technology. The test includes 19 tasks of two levels. The tasks of each variant are divided into two parts, which are compulsory and optional.

The experience of conducting the chemistry Unified State Examination shows that school leavers experience difficulties while fulfilling the C3 tasks, where they are to compose chemical equations in accordance with the transformation chain of matters. To fulfill such tasks successfully it is necessary to know production processes and chemical properties of organic matters of basic classes well enough. The author offers the chart, which systematizes such data.

The author shares the experience of conducting the lesson, where he gets students acquainted with new ideas such as «mole», «molar mass», «molar volume».

The article contains theoretical conditions and concise methodic recommendations on using virtual labs and video-experiments on the lessons. The author’s classification of the virtual chemical experiment is provided. General issues of methods of using virtual experiment while teaching chemistry are touched.

The technique of studying of properties toxic and smelly substances in the device for carrying out chemical reactions is offered. Features of a technique are safety, presentability, convenience and fast course of chemical processes.

In this paper the methods of estimating the purity of surface airlehinoindikatsii by using living organisms, bioindicators. As anindicator of living lichens were used.

In the spring the organism of each person lacks vitamins. For struggle against an avitaminosis, the invariable companion of spring, it is possible to replace tea and sparkling water with vitamin juice. The students having stress during session, should use vitamin C. He participates in formation of a hormone of adrenal glands of acetylcholine, calming an organism. The purpose of our research was quantitative definition of the maintenance of vitamin C in fruit juice a titration method.

Conducting complex excursions allows forming key competences, revealing inter-subject communications. This promotes further solid acquisition of knowledge, formulation of scientific ideas, scientific worldview, polytechnic and practical orientation of education effectiveness increase. While conducting excursions it is also possible to settle down the issues of career-guidance successfully. Getting students to know the ecological issues, which are considered during every excursion, encourages humanistic education.

One of the work types while organizing subject week is the “Knowledge Fair”. Each teacher composes questions, indicating the number of credits to be able to get for an answer. Questions on chemistry are provided.

his paper provides a brief sketch of the history of electrochemistry in Russia. Reviewed research our scientists in the field of electrochemical technologies of productions.
