基于知识图谱的“四学一体”混合式教学模式的实践应用——以“通信原理”课程为例

The Practical Application of the “Four-in-One” Blended Teaching Model Based on Knowledge Graphs—A Case Study of “Communication Principles” Course

摘要: 针对“通信原理”课程原理抽象、理论性强这一特点，以及混合式教学中面临的诸多挑战，本文创新性地提出了一种基于知识图谱的“四学一体”混合式教学模式。该模式以知识图谱为核心，通过整合线上线下资源，不仅为学生构建了系统性的知识架构，还精心设计了课前自学、课堂共学、课后伸学及实践验学四个环环相扣的学习环节，旨在全面增强学生的自主学习、协作与创新能力。同时，借助知识图谱可视化学情分析平台，实现了教学的精准定位与学生的个性化辅导，极大提升了“通信原理”课程的教学质量与学生的学习成效。

Abstract: In response to the abstract principles and strong theoretical nature of the “Communication Principles” course, as well as the numerous challenges faced in blended learning, this paper innovatively proposes a “Four-in-One” blended learning model based on knowledge graphs. This model centers around the knowledge graph, integrating online and offline resources to not only construct a systematic knowledge framework for students but also meticulously design four interconnected learning stages: pre-class self-study, in-class collaborative learning, post-class extended learning, and practical validation learning. The aim is to comprehensively enhance students’ autonomous learning, collaboration, and innovation abilities. Simultaneously, by leveraging a knowledge graph-based visual platform for analyzing learning situations, it achieves precise positioning of teaching and personalized tutoring for students, significantly improving the teaching quality of the “Communication Principles” course and enhancing students’ learning outcomes.
