摘要
针对结构化学课程知识点繁多和概念碎片化、学生难以形成学科框架和完整知识体系的困境,本文提出以"薛定谔方程-近似模型-核心概念-简单应用"为主线,以一维势箱自由粒子模型、单电子类H体系、多电子原子、H2+分子离子、H2分子、多原子分子等"六条分支"来构建学科的逻辑框架与知识点图谱.使碎片化的知识重构关联,形成完整的知识链,帮助学生理解重要概念的逻辑关系、产生脉络及相互联系,并且为学生提供知识迁移的情境,达到知识理解与运用的目的.
Abstract
In response to the challenges of numerous knowledge points and fragmented concepts in the structural chemistry course,as well as the difficulty for students to establish a disciplinary framework and a comprehensive knowledge system,this paper proposed a logical framework and knowledge graph,based on the thematic thread of "Schrödinger equation approximation models-core concepts-simple applications".This framework includes six branches:particle in box model,single electron hydrogen-like atoms,multi-electron atoms,H2+molecular,H2 molecules,and multi-atom molecules.By reconstructing fragmented knowledge and forming a complete knowledge chain,this approach aims to help students understand the logical relationships,generation context and interconnections of important concepts,and provides them with a context for knowledge transfer,ultimately facilitating their understanding and application of knowledge.
