The purpose of this study is to investigate the effect of using the Geometer’s Sketchpad software in the teaching and learning of graph functions among Form Six (Grade 12) students in a Malaysian secondary school. This study utilized a quasi-experimental design using intact group of students from two classes in an urban secondary school. Two instruments were used to gather information on the students’ mathematics achievement and attitudes towards learning graph functions.A survey questionnaire was used to gauge students’ perception on the usage of Geometer’s Sketchpad in the learning of graph functions.In the study, the experimental groups used Geometer’s Sketchpad-based worksheets and each student has an access to one computer equipped with the Sketchpad software. The control group used only the textbooks. Both groups took the same pre-test.This study indicated that the results ofthe experimental group had a significant mean difference compared to the control group. The use of Geometer’s Sketchpad in mathematics classroom has positive effect on the students’ mathematics achievement and attitude towards the learning of graph of functions also improved.
