Associate Head of the Legal Department of the Administration of the All-Russian Trade Union of the Education is answering our readers’ questions.

In article data on flavor modulators taste – glutamates sodium and . Questions of biological influence flavor modulators taste are considered and the assessment of their security of application for the person is resulted.

The statute and functions of the Fundamental nucleus of the basic education content are examined, advantages are shown and disadvantages of the Fundamental nucleus of the basic chemical education are disclosed, and concrete changes focused on enhancement of its structure and content, are offered in the article.

In learning process it is not possible to rest upon the classification as the peak of cognition. You should move from classification to systematization. The author examines classifications, which are extremely important for the chemistry learning: classification of inorganic matters and classification of inorganic reactions, and traces the extent, to which they are systematic ones.

The author examines peculiarities of module teaching and as an example of its organization offers the module lesson on the subject of “Ozone”

In the article briefly is described the meaning of teaching modul technology and substantiated the importance its employment in the middle schools of general education. Is recommended the learning ten subjects from the programme of chemistry of this technology, which were practiced by leadinq teachers of Azerbaijan in townspeople and rural schools. In the article also is etpounded the methodics of learning subjects of “Periodical law and periodical system of chemical elements. The structure of atom” from eighth grade. Is regarded course of separate lessons withdrawing to the modul cycle, aregiring the recommendations to the theachers for the optimum organization of each lesson.

The authors of textbooks, included into the active Federal list of textbooks, recommended by the Ministry of Education and Science to use in the educational process in educational institutions, answer the editorial staff questions.

Under the conditions of learning differentiation problems of teaching non-profile subjects gain especial meaning as far as their solution influences the assurance of robust student education to the great extent. The design of integrated lesson in the 11th Form of the humanitarian profile on the subject of “Chemical plots in belles-lettres” is offered.

The article considers problems with humanitarian component in modern school. Some problems with humanitarian component are given with solutions. These problems can be used in in-school work, additional work and as home assignment.

The author shows how to use of a document-camera at chemistry lessons.

The lesson is dedicated to the application of the idea of the standard number mode. Students, while accomplishing different operations with standard mode numbers, learn not only to carry chemical calculations, but progress in math as well.

The method of formation the skill to compose chemical equations of some oxidation-reduction reactions with oxygen-based organic substances is developed here on the basis of activity approach. The results of experimental approbation of the method allow its application for the specialized (profound) teaching chemistry and training teachers in system of additional education.

Binary and triple test tasks are a very effective instrument of knowledge appraisement, which gives a student a unique opportunity of self-development. While accomplishing a binary or triple task one can see for oneself a logical link between sections and different themes of the course. The author provides the examples of such tasks.

Only an insignificant number of chemical reactions is classified as elementary ones, in which initial substances react in one stage, forming final products. While the majority of reactions are a complicated process, which consists of two and more stages, in the course of which intermediate products are formed (intermediates). The article examines the reactions, in which a radical is formed as an intermediate, i.e. radical reactions.

The authors offer the development from the experience of the heavy metal salt influence on the living organism. The research was conducted in several stages. 1. Theoretic part. Studying academic fundamentals of the perused question (heavy metals, their behavior, and value, influence of metals on life process, toxicity level). 2. Experimental part. The influence of heavy metals on tomatoes. 3. The analysis of the conducted experiment.

Chemical experiment is one of the important methods of active learning. But too little attention is paid to it and time is allocated for it at schools. Students themselves recognize experiments to be extremely helpful to understand and learn the material studied, to form and develop skills of practical activity, increase interest to the science and wish to participate the scientific research. More part of the theoretical material is based on experimental works, better the studied material is learned, and higher the knowledge level.

The article narrates about one of the Cl.Arc. Timiryazev’s lectures, in which he developed ideas regarding the plant nutrition. Reminiscences of his contemporaries are provided.

Intellectual games increase the students’ interest towards chemistry, their motivation to study the subject, develop chemical intuition, attention, and logical thinking, and learn to correlate facts. Besides, students get plenty of new information, which broadens their outlook. The author provides questions to conduct game in different classes.
