基于雨课堂平台的知识图谱在《机械工程基础》课程教学模式探索

Exploration of Knowledge Graph Based on Rain Classroom Platform in the Teaching Mode of “Fundamentals of Mechanical Engineering” Course

摘要: 《机械工程基础》作为专业基础课，具有知识体系庞大、概念抽象、理论与实践结合紧密的特点。传统教学模式存在知识呈现碎片化、学生认知负荷高、学习路径单一等问题，难以满足新时代工程教育的要求。本文针对上述教学痛点，构建了一种基于雨课堂智慧教学平台的知识图谱教学模式。该模式首先通过梳理课程知识体系，构建了结构化的《机械工程基础》知识图谱；进而依托雨课堂的课前–课中–课后全流程教学功能，设计了“图谱引导的课前预习–图谱支撑的课堂讲授–图谱驱动的互动探究–图谱赋能的课后拓展”四阶教学流程；最后通过具体教学案例阐述了该模式的实施路径。实践表明，该模式能够有效实现知识的系统化与可视化呈现，促进学生的自主建构与深度学习，为提升课程教学质量和培养学生的工程思维能力提供了新的路径。

Abstract: As a fundamental course in the field of mechanical engineering, “Fundamentals of Mechanical Engineering” has the characteristics of a vast knowledge system, abstract concepts, and close integration of theory and practice. The traditional teaching mode has problems such as fragmented knowledge presentation, high cognitive load on students, and a single learning path, which are difficult to meet the requirements of engineering education in the new era. This article proposes a knowledge graph teaching model based on the Rain Classroom intelligent teaching platform to address the aforementioned teaching pain points. This model first constructs a structured knowledge graph of “Fundamentals of Mechanical Engineering” by organizing the course knowledge system; Furthermore, relying on the pre class, in class, and post class teaching functions of Rain Classroom, a four stage teaching process was designed, which includes “pre class preview guided by graphs, classroom teaching supported by graphs, interactive exploration driven by graphs, and post class expansion empowered by graphs”; Finally, the implementation path of this model was explained through specific teaching cases. Practice has shown that this model can effectively achieve systematic and visual presentation of knowledge, promote students’ autonomous construction and deep learning, and provide a new path for improving the quality of course teaching and cultivating students’ engineering thinking ability.
