基于知识树构建问题链的教学研究——以课程“工程力学”为例

A Study on Question-Chain-Based Teaching through Knowledge Tree Construction—A Case Study of the Course “Engineering Mechanics”

摘要: 针对目前工程力学课程教学中存在的内容碎片化、理论知识抽象、课程学时大幅减少、学生应用能力不强、教学模式单一等问题，本文提出了一种基于知识树构建问题链的教学模式，首先基于课程主线构建知识树，然后围绕知识树中的某一核心知识节点，遵循着该节点在知识树中的逻辑关系构建了层层递进的问题链。在工程力学课程教学实践中，按照导入、探究、深化、迁移、总结五个环节设置了问题链，引导学生自主完成了知识的理解与内化，进而实现了教学模式创新。

Abstract: In view of the current issues in the teaching of Engineering Mechanics, such as fragmented content, abstract theoretical knowledge, significantly reduced class hours, weak application abilities among students, and a single teaching model, this paper proposes a teaching approach based on constructing question chain through a knowledge tree. First, a knowledge tree is built around the main thread of the course. Then, focusing on a core knowledge node within the knowledge tree, a progressively layered question chain is constructed in accordance with the logical relationships of that node within the tree. In the teaching practice of Engineering Mechanics, the question chain is designed according to five stages: introduction, exploration, deepening, transfer, and summary. This approach guides students to independently achieve understanding and internalization of the knowledge, thereby realizing innovation in the teaching model.
