Development of an Online Engineering Drawing System to Enhance Junior High School Students' Learning in an Engineering Graphics Course

The purposes of this study were to develop the HappyCAD online engineering drawing system and to examine its effects on students' learning. The HappyCAD system includes instructional management and engineering drawing modules. The engineering drawing module provides three-dimensional (3D) models and interactive 3D solids. Learners can interact with the system and use various tools for drawing. Students can also receive feedback from teachers and redesign their engineering drawings. The HappyCADsystem was implemented as an e-learning tool in an engineering graphics course for junior high school students. Students' perceptions of online learning with HappyCAD in engineering drawing were reported along with learning outcomes that resulted from their use of the e-learning tool. This study demonstrated the positive effects of an online engineering drawing system on students' engineering drawing literacy. The finding suggests that students generated positive attitudes towards learning engineering graphics in an online environment. Students' error patterns in drawings were also analyzed in this study.
