Graphing Calculator and Geometers’ Sketchpad in Teaching and Learning of Mathematics
Keywords:Graphing calculator, Geometers’ Sketchpad, Straight Line topic, pedagogical usability
This study aims to develop a module for teaching and learning of Straight Lines topics using graphing calculator (GC) technology and dynamic geometry software, Geometer’s Sketchpad (GSP) and also to determine the pedagogical usability of the module. The study is carried out in two phases. Phase 1 is the development of the module and phase 2 is a survey research using a questionnaire. A sample of 30 mathematics teachers from three different schools in district of Sabak Bernam, Hulu Selangor and Kuala Selangor are randomly selected to participate in this study. The instrument used in this study is the pedagogical usability questionnaire. The pedagogical usability criteria are the student control, student activities, objective-oriented, application, value-added, motivation, knowledge value, flexibility and response. The data are analysed using descriptive statistics such as mean, standard deviation, percentage, and frequency. The findings showed that the module developed has a high pedagogical usability. 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 students.
