高分子物理难点突破：链段概念的教学

The Breakthrough of the Emphases and Difficulties in the Polymer Physics:the Teaching of Chain Segments

链段是高分子物理中一个非常重要的概念,但其定义却很模糊,这让老师的讲授和学生的理解变得非常困难。作者结合多年的教学实践,通过将学生熟悉的事物类比为高分子链的方法,结合启发式互动教学,有效地帮助学生理解链段概念的内涵,成功突破了这个难点。

Chain segment is a very important concept in Polymer Physics.However,its vague definition has made both the teachers＇ instruction and the students＇ understanding become very difficult.In this work,based on years of teaching experience,and through an analogy between polymer chains and students＇ familiar things in combination with enlightened interactive teaching,the authors have effectively helped students understand the essence,and successfully broken through the emphasis and difficulty of the ＂chain segment＂ concept.
