结合生活实际的《高分子物理》教学——以玻璃化转变为例

Combining the Daily Lives in Polymer Physics Education——in the Case of Glass Transition

针对高分子物理内容较为抽象的特点,结合作者的教学实践,提出将高分子物理理论与生活中的高分子现象结合,以提高教学效果。以玻璃化转变的讲解为例,通过生活中的玻璃化现象引入玻璃化转变的概念,实现物理现象与理论知识的结合;进而在对玻璃化转变机理的学习中,引入自由体积理论在生活中的真实应用,消除学生对理论知识的陌生感。在这样的教学过程中,既可以克服学生对高分子物理的抽象感又可以培养学生的观察能力和思考能力,达到学以致用的目的。

In viewing of the character of the polymer physics, an teaching way that combing the theory with the phenomena in our daily lives was proposed to improve the teaching effect. For example, in the teaching of glass transition, the concept of glass transition was introduce by analyzing of bubble chewing gum and realize the combination of physical phenomenon and theoretical knowledge. In the following teaching of glass transition mechanism, introducing the applications of free volume theory in real life to eliminate the strangeness of students. In the teaching process, students can not only overcome the polymer physics abstraction but also cultivate the observing ability and the thinking ability and achieve the purpose of application of knowledge.
