问题链教学法在结构化学教学中的应用——共轭分子休克尔分子轨道法

Application of Problem Chain Teaching Mode in the Teaching of Conjugated Molecules Hückel Molecular Orbital Method in Structural Chemistry

结构化学因其理论基础深奥、研究对象微观而难以被学生掌握。基于“问题链”的教学模式,以学生为主体,通过一连串由浅入深、由表及里的递进式问题引导学生思考,对改变学习方式、提高学习效果十分适用。以“共轭分子休克尔分子轨道法”为例,设计了基于深层学习的“问题链”教学模式。

Structural chemistry is difficult for students due to its profound theoretical foundation and microscopic research objects.The teaching mode based on the“problem chain”takes students as the main body and guides them to think through a series of progressive questions from the elementary to the profound and from the appearance to the essence,which is very suitable for changing learning methods and improving learning effectiveness.This article takes the“conjugated molecule Hückel molecular orbital method”as an example to design a“problem chain”teaching mode based on deep learning.
