أثر استخدام برنامج (Geometer’s Sketchpad (GSP على تنمية مهارات التحويلات الهندسية لدى تلاميذ المرحلة الإعدادية

الملخص EN

The current study aimed at exploring the impact of using interactive program geometer’s sketchpad (GSP) in teaching geometry on developing geometry transformation skills among preparatory stage students.

the researcher has prepared a program based on the interactive (GSP) program, the researcher also prepared a test for geometry transformation skills.

the study sample consisted of (96) students of the first year of preparatory school, it was divided into two groups, the experimental group numbering (45) students, and the control group numbering (51) students.

the researcher administered the study tools to gain pre-data, then teaching the unit using the interactive (GSP) program for the experimental group, and the unit was taught in the traditional way for the control group then the researcher administered the tools to gain post data.

the study results revealed that the performance of the experimental group students in the post data of the geometry transformation skills test outperformed their performance in the pre-data in the test as a whole and in each of its skills, also, the performance of the experimental group students in the post data of the geometry transformation skills test was superior to the performance of the control group students in the test as a whole and in each of its skills.

the study recommended training mathematics teachers on using interactive (GSP) in teaching mathematics, include school mathematics textbooks with activities to develop geometry transformation skills.
