DEVELOPMENT OF A METHODOLOGICAL APPROACH TO CONDUCTING EXPERIMENTAL EDUCATIONAL AND RESEARCH WORK OF STUDENTS IN PRACTICAL CLASSES IN CHEMISTRY

Abstract

The main task of the school is to combine training, development and education. And chemistry as a discipline makes a great contribution to the solution of this problem. Because laboratory work and practical classes in chemistry are the main part of professional training and theoretical training. Their focus is the experimental reflection, state of theoretical data and subject and professional practical activities. They are used not only as illustrations, but also as a cognitive tool. If a student can perform practical work in compliance with safety rules, conduct laboratory work, conduct observations during the experiment and summarize the results of the experiment, this will certainly Foster in him the ability to work independently and reveal the motivation for research. Therefore, an urgent problem is the innovation of experimental tasks and methods for carrying out work in accordance with modern requirements. In the article, the authors propose a new methodology for the effective conduct of experimental educational and research work of students in practical classes in chemistry. First, students are provided with visual aids and safety equipment for practice, then students are divided into groups of three people and can perform tasks. In order to be able to fully assess the level of knowledge and abilities of students, experimental tasks are divided into preliminary levels. It is assumed that this technique will reveal the abilities of the student, increase his attention and interest in the subject of chemistry.
