SOME METHODOLOGICAL FEATURES OF TEACHING SCHOOLCHILDREN TO SOLVE STEREOMETRIC PROBLEMS

The article deals with some methodological aspects of teaching school students to solve stereometric problems related to geometric bodies. Stereometric problems on polyhedra and bodies of rotation are studied in the last sections of the high school geometry program and are considered one of the most important topics for students of the natural-mathematical direction and specialized classes. The article is an introduction to the methodological foundations of a number of features for studying the subject of geometry at the level of students in grades 10-11. The article deals with the issues that lead to the inability to solve stereometric problems at the UNT (weakness of theoretical knowledge, the frequency of similar problems in a school textbook) and cause difficulties (weak ability to represent in space). Among the students, a survey was conducted on which tasks they first pay attention to during the UNT in the section of stereometry and in solving other problems. When analyzing the answers in the questionnaire, it was found that during the UNT, little or no time is allocated when solving problems of stereometry. The use of visual aids, multimedia technologies in the classroom for teaching the solution of stereometric problems, improving spatial imagination and self-education and the development of problem-solving skills, as well as the consideration of various methods of problem solving, showed a general positive perception of the problem in an easy and effective way.
