基于深度学习的“实验方案设计”主题式复习教学——以“阿司匹林的制备和提纯”为例

Review Teaching of “Experimental Scheme Design” Based on Deep Learning:Preparation and Purification of Aspirin

针对实验方案设计题的得分率分析和教学现状,基于课程标准、教材、真题和文献研究,构建“阿司匹林的制备和提纯”深度学习主题模型。通过设计制备和提纯阿司匹林的实验方案,构建实验方案设计的思维模型,并以制备七水合硫酸锌为例内化思维模型,在解决真实、复杂的问题过程中实现核心知识结构化,生成指向深度学习的主题式复习教学流程。

In view of the score rate analysis and teaching status of experimental scheme design questions,a deep learning theme model of “preparation and purification of aspirin” is built based on course standards,textbooks,real questions and literature research.Through the design,preparation and purification of aspirin experimental scheme,the thinking model of experimental scheme design is constructed.The preparation of zinc sulfate heptahydrate is taken as an example to internalize the thinking model.In the process of solving real and complex problems,the core knowledge is structured and the thematic review teaching process pointing to deep learning is generated.
