Spatial Ability, Descriptive Geometry and Dynamic Geometry Systems

Abstract

Dynamic Geometry Systems allow new opportunities for the teaching of
\ngeometry and descriptive geometry. These systems make possible to create
\ndynamic drawings quickly and flexibly. In the University of Debrecen Faculty
\nof Engineering we executed a controlgrouped developing research for
\ntwo years, one of them was at Descriptive geometry with participating first
\nyear full-time Mechanical engineer students and the other one was at Technical
\nrepresentation practice, in two-two practical groups, for trying out a
\nteaching-learning strategy. We taught one of the groups with the help of
\nDynamic Geometry System, the other one traditionally, with the paper-and-
\npencil method. In this paper, I report on our experiences of this course.
