Тhe article is devoted to an actual problem of ensuring quality of the general chemical education by means of formation of culture of chemical safety in the solution of problems of chemical education. A new understanding of the school of chemical education, which consists in fundamentalization of chemistry education through the integration of natural-scientific and humanitarian knowledges, providing optimization and quality of pre-vocational science education. The solution of the given issue is conditioned by the leading ideas, stated in documents of UNESCO, the National educational initiative «Our new school» and ФГОС.

Article is devoted to designing the content routing chemistry lesson on the basis of the system - the activity approach and the formation of universal educational activities. Proposed routing option allows lesson holistically to see the content of the lesson stages using the system - active approach , flexible use of effective methods and forms of work with students , teachers and harmonize the actions of students , to form specific personality , regulatory , cognitive and communicative universal learning activities to design individual educational route , taking into account the interests and needs of each student in accordance with the requirements of the GEF .

Blended learning arrangements combine e-learning with face-to-face learning and have become quite popular in modern education of several countries. This technology is new in Russian school. The article presents a general framework that describes didactical design decisions regarding the elements of a blended learning arrangement and the choice of the delivery system (models). The author focuses on the strengths and weaknesses of its using in secondary school.

We can achieve success in teaching chemistry through using visualization methods. The paper describes new visual method of chemical equation concept understanding and preparing a success in solving problems. This method includes four stages: writing chemical equation, reading chemical equation, understanding of chemical equations, using chemical equation.

The scenario of the lesson on the topic “The uses of sulfuric acid” with the technology of variable students’ groups is presented in the paper.

Presented sets of cards with the formulas of inorganic substances and assignment of students to work with them.

The current article is written about adjustment methods of redox reactions. The author states that the visibility and effectiveness of electronic balancing and half-reaction methods can be increased in the case if there in terms of general approach is a combination of both, electronic balancing and half-reaction methods, which is then called method of electronic half-reaction balance. To implement the proposal author suggests adjustment process equalizing amount of electron given and amount of electron received as well as process of transmission of half-reaction, which are reflected on the general picture of sequence.

The paper considers tasks of chemical formulae inference and an algebraic algorithm for determination of element using parametric equations.

A significant place in the content of the course chemistry is given chemical experiment. It opens up the possibility of forming students ' specialised skills to work with substances which teaches students the safe and proper handling of substances in class, at home and at production. The main role of practical work is the development of students ' scientific thinking, formation of skills of intellectual penetration into the essence of the studied phenomena, to encourage interest in science, in communion to the scientific research, etc. Practical work should be done with due account of the interests of the students, to have a practical focus to wear an element of entertainment. Statement of problem issues, modeling of problem situations, creative tasks should become a logical addition to the lesson. Such activity approach in teaching chemistry makes a successful practical work, increases the interest to the research activity of pupils and the subject in General.

The visualization principle is one of the basic didactic principles, and the main method of studying chemistry as a natural science is an experiment. Hence, starting with the first lessons of chemistry for the 8th grade, the author carries out practical activities in order to get the students acquainted with physical properties of substances, conditions and characteristics of chemical reactions by demonstrating electrical conductivity of salt solutions and electrolysis of water.

In the paper the interconnection between structure and properties of organic compounds as well as the influence of atoms and groups of atoms on the reactivity of substances is presented through experiment.

In the article food value and testing meat foods quality are considered according to the organoleptic indexes with the help of chemical methods based on analytical reactions. The application of luminescence analysis is demonstrated in the sphere of testing meat grade of freshness and class property.

The paper deals with complex excursions as the central element of the project “Education for life”. The purpose of complex excursions is an introduction of students into the world of jobs, the development of integral conception of technological production cycle and the formation of students’ social competences. Industrial site excursions and their preparation are described in detail. The use of instructive maps, group and case technologies, is shown.

This article is about the incarnation of Mendeleev’s ideas regarding Tobolsk.
