USING THE SOFTWARE GEOGEBRA AS A MEANS OF VISUAL LEARNING IN TEACHING HOW TO SOLVE TRANSFORMATION PROBLEMS

Abstract

Geogebra is a special mathematical software used freely in the world and has the interface in Vietnamese. It combines the dynamic environment geometry, dynamic algebra and dynamic calculations. By using Geogebra, teachers can produce geometrical figures or solve functions and manipulate coordinate expressions. Moreover, Geogebra has a sector for inputting information about the object directly. This paper presents the use of dynamic mathematics software GeoGebra as a means of visual learning to help students in predicting, demonstrating, illustrating, limitting and extending transformation problems in high schools.
