“学以致用”的高分子化学实验改革——以“家用高分子防火凝胶”为例

The Reform of Polymer Chemistry Experiments of “Learning to Use”——Taking “High Water-Retaining Household Polymer Fireproof Gel” as an Example

传统高分子化学实验往往侧重于不同聚合机理及聚合方法的罗列,注重学生基本理论及基础实验技能的培养。教学过程中,以教师讲授以及学生根据特定实验步骤重复为主。笔者结合自身近5年本科生高分子化学实验的教学情况发现,在传统高分子化学实验过程中,学生缺乏主动性和能动性,实验结束并撰写完实验报告后很快会将相关实验遗忘,实验教学效果欠佳。思考如何将高分子科学相关知识与人们的日常生活密切联系到一起,增加学生的学习兴趣、实验趣味性及实际意义至关重要。本文以"高保水型家用高分子防火凝胶"为例,探索"学以致用"的现代高分子化学实验的可行性。结果表明,学生对该实验兴趣浓厚,实验结束后绝大多数同学感到自己可以综合应用高分子科学相关知识来解决实际问题,并能获得一定"成就感",实验教学效果良好。

Traditional polymer chemistry experiments mainly focus on different polymerization mechanisms and polymerization methods, especially focusing on the basic theory of students and the cultivation of basic experimental skills. In the teaching process, teachers are taught and students are merely based on the specific experimental steps. The author combined with the teaching situation of polymer chemistry experiment in the past 4 years, found that in the experimental process of traditional polymer chemistry, students finished their experiments without passions and lack initiative. After the experiment, the relevant experiments will be forgotten soon. The experimental teaching effect is not good. It is important to think about how to closely link the knowledge of polymer science with people’s daily life to increase students’ interest in learning, the fun of experiment and the practical significance. This article takes "high-water-retaining household polymer fire-retardant gel "as an example to explore the feasibility of the" study-to-use" modern Polymer Chemistry Experiment. The results show that students have a strong interest in the experiment. After the experiment, most students feel that they can apply the knowledge of polymer science to solve practical problems and have a certain sense of accomplishment. The experimental teaching effect is good.
