Features and effectiveness of using dynamic geometry systems in the geometric training of future mathematics teachers
The article discusses the features and effectiveness of using dynamic geometry in teaching geometry to future mathematics teachers and describes the results of the research. It is known that the maingoal of teaching geometry in pedagogical universities is to develop the necessary knowledge, skills, scientific outlook, development of mathematical thinking, and interest in geometry in a teacher of mathematics. To achieve this goal, a system of geometric education with modern technologies for presenting and studying the material is needed, which focuses not only on traditional teaching methods but also on methods that contribute to the formation of creative thinking, and non-standard views. The article describes the currently used systems of dynamic geometry. To train students using digital educational resources, the GeoGebra dynamic geometry system was chosen - an interactive computer program for all levels of education that combines geometry and algebra, tables, graphs, statistics, and mathematical analysis. The article presents several tasks used by students during practical classes on the section «Polyhedra» and their digital 3D models using GeoGebra. The experiment involved the 2nd year students enrolled in the educational program «Mathematics». According to the results of the experiment, the control and experimental groups were tested to test their knowledge of geometry, consisting of the topics studied during the course. With confidence of 0.95, it was found that there was a significant difference in geometric training between the control and experimental groups.
