A1 حسين، هشام بركات بشر AB This research aim's to explorer the Efficacy of Dynamic Geometry Software (Cabri-3D) in Teaching Spatial Geometry at High School on Geometrical Thinking and Attitude towards Mathematics. The research used the quasi experimental methodology with sample (50) high school students that’s divided equally to experimental group and control group. The experimental group studied with (Cabri- 3D) and the control group studied with normal teaching strategies. With pretest - posttest for; (van Hiele test, Attitude toward mathematics scale, Achievement test). The result revealed that the geometric level of the sample was the third level of van Hiele levels, there are Efficacy of Dynamic Geometry Software (Cabri-3D) in Teaching Spatial Geometry at High School on Achievement Spatial geometry, but there are no Efficacy on Geometrical Thinking and Attitude towards Mathematics. Suggestion and proposal were presented.
