USING INFORMATION TECHNOLOGIES FOR THE ACQUAINTANCE OF STUDENTS OF SECONDARY SCHOOL WITH THE THEME "SET"
The article describes the continuity in teaching the elements of the set theory on the levels of preschool, primary general and basic general education. The relevance of studying the theme "Set" is grounded. The result of the analysis of educational and methodical literature on this theme is described, showing that in the basic school at the proper level neither the definifions nor the ideas of the set theory are stated, which entails the students' difficulties in mastering this theme. In this regard, to improve the efficiency of the study, it is proposed to use the Maplet-applications developed by us using Maplets library of the system of computer algebra Maple: "Union of two sets", "Intersection of two sets", "Difference of two sets", "Symmetric difference of two sets", "Addition of one set to another". These Maplet applications allow to interactively perform basic operations on sets, control students' knowledge of the order in which these operations are performed, and can be the starting point for solving more complex set theory problems.
