THE USE OF MEDIA EDUCATIONAL TECHNOLOGIES IN SOLVING IDENTICAL TRANSFORMATIONS OF EXPRESSIONS IN THE ALGEBRA COURSE IN INSTITUTIONS OF GENERAL SECONDARY EDUCATION

Abstract

An important place in the school mathematics course is given to the study of the content line of the course –expressions and their identical transformations. A culture of performing identical transformations is developing,based on established knowledge of the properties of operations and algorithms for their execution. A high level of performing identical transformations is manifested in the ability to justify transformations, in the ability to detecta change in the domain of definition in a sequential chain of identical transformations, as well as in the speedand error-free execution of transformations.The article reveals the methodological features of the study of identical transformations and the studyof the level of success of students in the algebra course in general secondary education institutions usingthe analysis of psychological-pedagogical and methodical literature, teaching-methodical manuals, textbooks,didactic materials for studying the experience of leading teachers.The results of a pedagogical experiment on the level of success of students in identical transformationsof expressions in the algebra course in institutions of general secondary education are presented. A comparativeanalysis of programs and textbooks on the topic “Identical transformations of expressions” is presented. Themain types of identical transformations of expressions in the algebra course in institutions of general secondaryeducation and the stages of their study are highlighted. The concept of “media-educational technologies” asa means of presenting information to interest students in mathematics lessons is revealed. The main typicalmistakes made by students in the process of performing identical transformations of expressions are analyzedin detail, possible ways of their prevention and elimination are given.The research is devoted to a topical topic, because in the process of studying the transformations of expressionsin the course of algebra, students develop the necessary skills for solving equations and inequalities, as well asfor proving identities. Media technologies are a key concept that includes technical, instrumental techniques,techniques, as well as semantic and artistic ones, it is a means of stimulating the desire for self-education,self-training, and the constant desire for knowledge. An experimental test of the level of success of students(tasks developed for self-explanatory work) was carried out from identical transformations of expressions inthe algebra course in institutions of general secondary education, namely, with the help of Pearson’s criterion,scores from independent work of students of the 11th grade were compared.
