PREVENTION OF STUDENTS MISTAKES WHILE STUDYING THE TOPIC “WHOLE EXPRESSIONS”

Keywords: methodical receptions, basic secondary education, algebra, typical mistakes, preventive activity

Abstract

Among the semantic lines of the school course of algebra, the line of expressions and their transformations is essentially significant. Free execution of the main types of transformations of whole and fractional, rational and irrational expressions is a prerequisite for further successful mastering of other semantic lines. Therefore, the provision of strong knowledge and skills on identical transformations of expressions should be the subject of constant attention of the mathematics teacher. The article considers typical mistakes of students during the study of the semantic line of expression and transformation of expressions, the course of algebra in institutions that provide basic secondary education, namely in the process of studying the topic "Whole expressions". The analysis of the most widespread mathematical errors of schoolboys, psychological and pedagogical preconditions of their occurrence is carried out. The method of organization of preventive activity of the teacher of mathematics is offered (under preventive activity of the teacher of mathematics we understand activity which is initiated by necessity: to prevent mathematical mistakes of pupils, to correct the admitted, having found out the reasons of their occurrence and to choose rational methods and transformations of whole expressions. Preventive activities should be organized as a process of interaction between teachers and students, during which through specially selected methods, firstly, reveals the origin of errors, and secondly, organizes work to prevent and correct them. The main task of the formation of preventive activities of students is to develop their ability to independently adhere to all its structural components. The result of such activities largely depends on how the teacher understands the structure of mental activity of students in specific learning conditions, is able to take into account the objective patterns of learning material, psychological and pedagogical patterns of perception and memory. The effectiveness of the proposed method was tested by the author in the research process: “Methodical system of analysis and prevention of mathematical errors in the study of algebra in primary school”.
