Constructing a New System of Three-Dimensional Engineering Graphics Teaching Based on OBE

Based on a new system of integrated mechanical engineering teaching within an Engineering Graphics curriculum, following the outcome-based-education (OBE) concept as a key guideline, mainly relying on in-classroom format of teaching, integrating and exploring additional extracurricular teaching resources, this study constructs an “online-to-offline integrated teaching platform” that promotes students’ ability and motivation for learning using various “Internet+” technologies and tools. This new and all-around multi-dimensional Engineering Graphics teaching system “integrates in-class learning and after-class learning, combines online tools and offline tools, brings together mandatory courses and open-ended hands-on experiment courses, bonds teachers with students, and integrates theory and practice.” Through seven years of practical teaching experience, the system has gradually improved, and could reasonably resolve some common problems that have previously troubled lots of teachers of fundamental-level engineering curriculum--problems such as insufficient scheduled hours in class, excessively high student-teacher ratio, lack of hands-on experiments or practice, insufficient after-class supplementary assistance, and students’ relatively low self-motivation in learning. Decent teaching results have been observed through the new system, and can provide some reformatory ideas for teaching basic engineering curricula.
