The Penetration of Abstraction and Analogy in the Teaching of Organic Molecular Structure under the Hybrid Learning Model

Ball-and-stick models and various projection formulas that describe the three-dimensional structures of organic molecules serve as important vehicles for integrating abstraction and analogy. However, these related knowledge points are scattered throughout multiple chapters of the textbook, making it difficult to cover them comprehensively in traditional classrooms with limited class hours. Nevertheless, blended learning supported by information technology offers an opportunity to address this challenge. By integrating knowledge through comprehensive lectures and using methods of penetration, immersion, and enlightenment, the implementation process of abstraction and analogy can be partially restored. This approach focuses on clarifying the different roles of ball-and-stick models and their projection formulas in expressing molecular three-dimensional structures and connects with the scientific methodology to achieve a subtle and effective educational impact.
