Achieving Effective Learning Using Student-Generated Screencasts in Computer-Aided Design EducationScreencast tutorials have been widely used in the computer-aided design (CAD) education. Ascreencast tutorial is a digitally recorded playback of a computer screen output, which oftencontains audio narration, to visually present procedural information. Screencast enables the quickcreation/development of software tutorials and allows the instructors to update the learningmaterial frequently in order to keep up with the pace of software evolution. However, in currentCAD education, the screencasts are often created by the instructors. The students learn about theCAD software by watching the screencast and following the procedures. This conventional useof screencasts in learning has some deficiencies. The students are mostly kept in a passive role inthe learning process. They do not participate in designing the material that they learn.This paper presents the preliminary findings of an engineering education research project fundedby the National Science Foundation. In the project, an evidence-based pedagogy wasimplemented in the CAD education. Instead of using the instructor-generated screencasts,students were asked to make screencasts on their homework problems and share with all otherstudents in the freshman Mechanical Engineering Drawing class. Following an experimentalstudy design, students were grouped into two as control versus experimental. In the controlgroup, students received traditional teacher-centered instruction without designing their ownscreencast tutorials. In the experimental group, students designed their own screencast tutorialsthat provided them with the feelings of belonging and ownership to their learning tasks. Studentsshared these tutorials with one another that would potentially help them develop life-longlearning skills. The students’ learning outcomes were assessed, including their attitudes towardsengineering, their life-long learning skills, and CAD knowledge. A CAD modeling test was usedat the end of semester to assess students' CAD modeling skills. The engineering attitude surveyand the life-long learning scale were administered at the beginning and the end of semester.Students’ learning outcomes and the changes in these measures are presented.
