INTEGRATING WEB SKETCHPAD INTO ONLINE COURSES FOR TEACHING ROTATION TOPICS

Web Sketchpad is a new technology based on The Geometer’s Sketchpad software, featuring a highly simplified user interface and customizable tools, allowing learners to focus on mathematical exploration experiences to construct their own knowledge. This study integrated two dynamic mathematical representations designed on Web Sketchpad into an online course to support students in exploring the topic of Rotations in the plane. The results show that Web Sketchpad on the Moodle platform supports students well in conducting mathematical explorations related to rotations. It can serve as a cognitive tool and support different stages of mathematical problem-solving. The students in the experiment demonstrated problem-solving and creative competency, independently constructing new mathematical objects, searching for and discovering mathematical relationships. Additionally, they had the opportunity to practice self-directed learning and self-study through heuristic exploratory activities with dynamic mathematical representations.
