The purpose of this study was to develop pre-service secondary teachers' technological pedagogical contentknowledge (TPACK) for teaching mathematics with The Geometer’s Sketchpad (GSP) through Lesson Study(LS). Specifically, a single-group pretest-posttest design was employed to examine whether there was asignificant difference in the pre-service secondary teachers' TPACK for teaching mathematics with GSP afterengaging in LS which was incorporated into the mathematics teaching methods course during the first semesterof the 2011/2012 academic session in a Malaysian public university. Forty-six pre-service secondary teacherswho enrolled in the course completed both the pretest and posttest questionnaires on teachers' TPACK forteaching mathematics with GSP. The results of the paired-samples t-test indicated that there was a significantdifference in the pre-service secondary teachers' TPACK for teaching mathematics with GSP for all thesubscales after engaging in LS.
