Exploration of Heuristic Teaching in the "Information and Network Security" Course Based on the OBE Concept

Abstract

In the "Information and Network Security" course, cryptographic techniques pose challenges as they involve extensive mathematical knowledge that is complex and hard to comprehend. Additionally, during the traditional teaching process, the basic knowledge of cryptographic mathematics and the application of cryptographic techniques are often taught separately, leading to suboptimal teaching outcomes and low student learning initiative. This research group proposes an OBE - oriented modular and guided teaching mode, integrating lectures and practices and leveraging an online course management platform. The aim is to enhance students' enthusiasm for autonomous learning and improve the overall teaching effectiveness of the course, considering the relationships and coherence among knowledge points in each chapter.
