Abstract

Focusing on the teaching reform of data structure courses, this paper constructs and practices an online and offline hybrid teaching mode based on the concept of Outcomes Based Education (OBE) in view of the problems of disconnection between theory and practice, single teaching method and imperfect evaluation system existing in the traditional teaching mode. This model takes student ability as the core, and realizes the transformation from "teacher-centered" to "student-centered" by clarifying curriculum objectives, reconstructing teaching content, innovating teaching methods, and reforming the evaluation system. Through a semester of teaching practice, the study uses the method of comparing experimental classes with control classes, and systematically evaluates basic knowledge mastery, practical ability performance, learning process performance and other dimensions. The results show that the experimental class is significantly better than the control class in terms of final exam scores, algorithm design ability, project completion quality and independent learning ability, especially in the understanding and application of complex data structures such as trees, binary trees, and graphs. This study verifies the effectiveness and feasibility of OBE concept and hybrid teaching mode in data structure courses and its methodology of "goal guidance-reverse design-continuous improvement" provide useful reference and practical examples for the teaching reform of basic engineering courses.
