摘　　要：众所周知,无论是中学还是大学,杂化轨道理论始终是化学教学中的重点、难点。它是大学基础化学的重要内容之一,在分子空间结构分析、成键特点、键角计算以及有机化学反应机理的学习中,都存在它的应用。能够熟练应用该理论,也是后续学习高等结构化学、高等无机化学等课程的基础。但由于太过抽象,绝大多数学生对此都很难以理解,甚至有些教师也比较模糊;尽管有实物模型、多媒体素材等辅助工具,但在讲授的时候依然不方便。本研究通过化学模型教学策略——建立杂化轨道的Matlab模型,让学生借助Matlab软件来实现对杂化轨道的可视化,从而提高教学效果,强化学生对知识的理解。As is well known,whether in high school or university,the theory of hybrid orbital has always been a key and difficult point in chemistry teaching.It is one of the important contents of basic Chemistry in universities and has applications in molecular spatial structure analysis,bonding characteristics,calculation of bond angle and learning of organic chemical reaction mechanisms.Being able to proficiently apply this theory is also the foundation for subsequent courses such as Advanced Structural Chemistry and Advanced Inorganic Chemistry.But due to being too abstract,the vast majority of students find it difficult to understand and even some teachers are quite vague.Although there are physical models,multimedia materials and other auxiliary tools,it is still inconvenient to teach.A teaching strategies was adopted for chemical model——establishing a Matlab model of hybrid orbitals and allowing students to use Matlab software to visualize hybrid orbitals,thereby improving teaching effectiveness and strengthening students understanding of knowledge.
