摘要：

重排反应有着不同于加成、消除及氧化还原等其他类型基础有机反应的独特性，是在有机合成课程中学生普遍反馈难以理解和记忆的教学内容。在基础有机化学课程的教学中，重排反应相关知识点散落在各个章节，学生对于这部分内容缺乏深层次的理解以及内在关联性的认识。因此，搭建零散的相关重排反应之间的关联，开展重排反应的深度学习教学显得尤为重要。本文结合有机化学学科的特点，根据有机合成教学现状，围绕深度学习教学设计的四要素，把握深度学习的四大特征，以教学片段为例阐述深度学习理论在教学实践中的应用。

Abstract:

Rearrangement reaction is one of the important but unique teaching contents in organic synthesis course, as it seems very different from the basic organic reactions, such as substitution reactions, addition reactions, elimination reactions, oxidation and reduction. In fact, rearrangement reactions are involved in many chapters of organic chemistry course, which makes it hard for the students to get a deep understanding of these types of reactions and clarify the relationship between them. Therefore, the development of teaching practice in a deep leaning manner is of significant importance. Based on the characteristics of this course and the current teaching situation, we focused on the four characteristics of deep learning, and took teaching clips as an example to illustrate the application of deep learning theory in organic synthesis.

Key words: Deep learning, Rearrangement reaction, Academic thinking, Teaching application
