This paper presents a new method of using peer-generated screencast in the computer-aided design (CAD) education. Instead of using instructor-made screencasts, students were asked to make their own screencasts, review each others’ screencasts, and provide feedback. To explore the impact of student-made screencast exercises on students' learning outcomes, we conducted a pretest posttest quasi-experimental research. A life-long learning survey, an engineering attitude survey, an exit project survey, and a CAD modeling exam were used as the study instruments. Among the students enrolled in six different sections of a CAD course, 110 of them completed all research instruments and participated in the study. This is a continuing research project, sponsored by the National Science Foundation, starting from Fall 2014. In Fall 2014 and Spring 2015, students in the experimental groups completed one screencast exercise after completing a trial exercise. Findings indicated that the students would like completing more than one exercise. Therefore in the second year, we asked the students in the experimental groups to complete more than one screencast exercise in addition to completing the trial exercise. Findings from the past two years indicated that the students in the experimental groups performed better than those in the control groups in the CAD modeling final exam.
