Abstract:Based on the professional accreditation requirements and the CDIO education concept, several cyclical project-based teaching explorations are carried out. The feasible plan of the integrated teaching construction about two-level projects and three-level projects are studied and implemented. For the three-level projects, we should pay attention to how to make full use of the existing teaching resources to conceive ideas and design, and emphasize practical training during the implementation of the project. For the two-level projects, the assessment content about the promotion project of the national large-scale enterprise engineer is appropriately expanded as the project title, and the core contents and main points of the multi-curricular curriculum of the professional course group are integrated into it, focusing on the internal connection between the two-level projects and three-level projects, and on the connection between the teaching process and professional internships and professional experiments. In accordance with the "design institute model" and "engineering habits",the students can get "quasi-engineer" training, and the joint teaching of the teachers′ team has enabled the implementation of the goal and plan for the integrated project-based teaching construction, and has gradually realized the indicators of professional certification.
