摘要:

休克尔分子轨道理论是结构化学课程中的重要内容,可预测或解释共轭分子性质、电子光谱等问题。其与势箱中粒子运动模型、分子轨道理论、分子对称性等知识点关联密切,综合性强。在该理论教学过程中运用问题式教学法(Problem-Based Learning,PBL),以典型问题引导学生自主学习,在循序渐进的问题中,学生的思考意识逐步增强,知识综合能力可得到有效提升。

Abstract:

Hückel molecular orbital (HMO) theory is an important and comprehensive topic in the course of structural chemistry, which can predict or explain the properties and electronic spectra of conjugated molecules. It is closely related to the concepts such as one-dimensional potential well, molecular orbital theory and molecular symmetry. In the teaching process of this theory, the use of Problem-Based Learning (PBL) methodology can guide students to learn independently through typical problems. Through progressively designed problems, students' thinking awareness is gradually enhanced, and their comprehensive knowledge and abilities can be effectively improved.

Key words: PBL methodology, Structural chemistry, Hückel molecular orbital theory
