Exploration on Teaching Reform for the"Database Principles and Applications" Course Based on CDIO-OBE Concept

Abstract
Aiming at the problems existing in the traditional teaching of "Principles and Applications of Database Systems" for software engineering majors in private application-oriented undergraduate universities—such as overemphasis on theory while neglecting practice, significant differences in students' foundational knowledge, and a single evaluation method—this study integrated the CDIO (Conceive-Design-Implement-Operate) engineering education model with the OBE (Outcome-Based Education) concept, and implemented a systematic teaching reform using the "Student Performance Management System" as the core teaching case. Following the CDIO process of "Conceive-Design-Implement-Operate" and relying on SQL Server as the database tool, student-centered project-based teaching was carried out. Adhering to the logic of "reverse design and forward implementation", a three-dimensional objective system covering knowledge, competence, and quality was reconstructed. Progressive project-based teaching was adopted, along with a differentiated strategy of "stratified grouping + flexible tasks", and a multi-dimensional assessment system consisting of "process evaluation (60%) + summative evaluation (40%)" was established. Teaching practice shows that this model effectively stimulates students' learning initiative, and significantly enhances their engineering practice and teamwork abilities. The CDIO-OBE integrated model can effectively improve the teaching quality of application-oriented courses in private universities, providing a referable path for the reform of similar courses.
