ON USAGE OF INDUCTIVE APPROACH IN MATHEMATICAL TEXTBOOKS AT SECONDARY SCHOOL

Summary/Abstract: Quality of mathematical education is very actual didactic issue at present. One possibility how to increase it is a use of unconvencional experimentally inductive approach. The appropriate textbook then can be a useful helper for teacher who intends to apply this approach. There are given an analysis of the usage of inductive and deductive approach in mathematical textbooks here. The research was focused on the content of mathematics textbooks for secondary school, on their interpretative and exercise text components, respectively. The main interest was to explore the representation of inductive and deductive methods in interpretation of the mathematics textbooks and to measure the content of the exercises whose student's solution requires the use of heuristic approaches. The results of the analysis show that each author prefers a different approach to interpretation which is used in the writing of textbooks. Interpretative means most contained in all the textbooks are a direct interpretation with the motivation (34.4%), a direct interpretation without motivation (31%) and an indirect interpretation with the motivation (24.5%). Inductive and deductive interpretative means are only rarely represented in all the textbooks. The highest rate was registred in the case of task using interpretation with the motivation (7%).
