依托真实情境构建问题解决模型的教学——合成高分子复习课

Construction of Problem-Solving Model Based on the Real-World Situation:Review Teaching of Synthetic Polymer

以可降解塑料为真实情境,将高分子的典型合成方法作为明线,将合成、结构和性质作为暗线,从“碳骨架、官能团、化学键”的微观结构视角分析合成高分子化合物的方法及合成条件选择,建立结构视角下的真实问题解决模型,发展学生“宏观辨识与微观探析”“证据推理与模型认知”的核心素养。

This lesson is set in the real-world situation of several degradable plastic materials.The lecture is driven by the exploration into typical ways of synthesizing polymers,while in this course knowledge about the synthesis,the structure,and the properties of chemicals will be shared.It takes the micro-structure perspectives of the carbon skeleton,functional groups and chemical bonds to analyze the methods and conditions of polymer synthesis.A model for solving practical problems from the structure point of view will be developed through the lecture.In addition,students will be able to develop their abilities of macroscopic perception and microscopic analysis,as well as evidence-based reasoning and model-based understanding.
