Research on PBL Teaching in Engineering Graphics from the Perspective of Constructivist Theory

This paper aims to explore the application of problem-based learning (PBL) teaching method in the engineering graphics from the perspective of constructivist theory. Firstly, the paper introduces the basic principles of constructivist theory in the field of education, emphasizing that learners construct knowledge and skills through active participation in the process of solving real-world problems. Secondly, the paper elaborates on the main features of PBL teaching method, including problem-centered learning, self-directed learning and teamwork learning. Subsequently, the paper discusses the design and implementation strategies of PBL teaching in the engineering graphics, including how to select appropriate teaching scenarios, guide students in self-directed learning and teamwork learning, and evaluate learning effectiveness. Finally, the paper concludes the positive effects of constructivist theory and PBL teaching method in the teaching practice of engineering graphics course.
