Research and Practice on Teaching Innovation of Experimental Courses for Electrical Engineering Majors from the Perspective of Industry-Education Integration

Taking the Practical Course of Electrical Control and PLC as an example

Abstract

In view of the problems existing in the experimental courses of electrical engineering majors, such as insufficient connection between course content and industry, weak personalized support of teaching resources, and weak engineering practice orientation, an innovative experimental teaching system of "three-chain synergy, three-stage progression, and six-step guidance" is constructed based on the CDIO engineering education model and cognitive apprenticeship theory. By integrating the problem chain, resource chain, and mentor chain throughout the entire process of pre-class, in-class, and after-class, and through the hierarchical advancement of virtual simulation practice, hardware operation verification, and engineering innovation improvement, reconstruct the three-stage experimental content of "comprehensive design - engineering practice - innovative application", and create an integrated resource ecosystem of "digital twin + virtual simulation + cognitive apprenticeship", Establish a closed-loop evaluation system of "evaluation - feedback - improvement" that is data-driven, multi-collaborative, and ideological and political integrated. The curriculum is deeply integrated with elements of ideological and political education such as engineering ethics, craftsmanship, and patriotism, achieving a trinity of knowledge imparting, ability development, and value shaping. The teaching reform has significantly enhanced students' engineering practice, innovative design and job fit capabilities. In the past three years, students have won more than 30 national competition awards, 49 provincial-level and above innovation and entrepreneurship projects, and 63 authorized patents. The course has been recognized as a provincial first-class undergraduate course, a provincial model course for ideological and political education, and has received numerous honors such as the first prize of provincial teaching achievement and the second prize of teaching achievement of the Chinese Society of Simulation. The achievements have been promoted and applied in more than 20 majors within the university and more than 10 institutions within and outside the province, providing replicable and promotable practical models for the cultivation of high-quality technical and skilled talents in the field of intelligent manufacturing.
