Screencast is an effective learning tool for computer-aided design (CAD) education. In the screencast, the procedural operations of making three-dimensional (3D) models are presented visually along with the audio narration, which is effective and intuitive. Traditionally, instructor-made screencasts have been given to students after class for reinforcing their learning. However, the students have been kept in a passive role in this learning process. Students did not participate in designing the material that they learn. This poster presents the implementation of a student-centered instructional strategy in teaching CAD in the undergraduate level. Student participants were asked to generate the screencast tutorials in groups and then share them with their peers in a collaborative learning environment. Students watched the peer-generated screencasts online and provided feedback. The students’ learning outcomes, including their CAD modeling skills, engineering attitude, and their life-long learning skills, are assessed. In addition, experimental group students completed an exit survey that explored their experiences. Selected students in the experimental groups were interviewed. We used quantitative tests to analyze all the data collected.
