The purposes of this quantitative research are to develop a module that integrated a graphing calculator (GC) technology and dynamic geometry software, Geometer’s Sketchpad (GSP) in mathematics teaching and learning of Straight Lines topic and to investigate its pedagogical usability. A group of pre–service mathematics teachers from Sultan Idris Education University participated in the training sessions where they evaluated the pedagogical usability criteria namely the student control, student activities, objective–oriented, application, value–added, motivation, knowledge value, flexibility and response. The GC–GSP module was developed based on ADDIE model that integrate the TI–84 Plus GC and GSP. The results showed that the module met the requirements of the pedagogical usability criteria mentioned. Findings from this study provide evidence of pedagogical impact in incorporating the latest trends in mathematics education, namely, integrating the GC tool and GSP software to maximize the mathematical and pedagogical benefits to Malaysian students.
