The effective learning strategies for mathematics topics may vary according to the topic. For geometry, the activities that are suggested to be implemented are carried out using Van Hiele's phases of learning geometry. The phases include Information, Guided Orientation, Explicitation, Free Orientation and Integration. The implementation of these phased-based activities is easier and more effective with the presence of dynamic geometry software, especially the Geometer's Sketchpad (GSP).

The developed activities were given to eight experts to get their views on the activities. Besides that, 24 pre-services teachers were also given the activities for the purpose of investigation of paedagogical usability of the developed activities. The results showed that the developed activities were well-arranged based on Van Hiele's phases of learning geometry with the assistance of GSP. The results also showed that the developed activities met the requirements of the pedagogical usability criteria. Since these phase-based activities obtained positive views from experts and pre-services teachers, the activities can be carried out in teaching and learning geometry.
