高分子化学实验的问题引导式教学

Question-Inductive Teaching of Polymer Chemistry Experiment Course

针对高分子化学实验传统教学(预习-实验操作-实验报告)存在的问题,以"甲基丙烯酸甲酯的自由基聚合实验"为例,探讨问题引导式教学实施方法,通过效果对比法验证问题引导式教学法的优势。问题引导式教学法加强了高分子化学理论课和实验课之间的相互支撑,引导学生更好地利用理论知识完成实验,同时在实验中深化对理论知识的认识。

In order to address the problems in traditional teaching of polymer chemistry experiment course(preview-operation-report),using an typical example of"Radical polymerization of methyl methacrylate"in this paper,question-inductive teaching method and its procedure were discussed,and the advantages of the teaching method herein was ascertained by effect comparison.Inductive questions in preview stage include the experimental principles,the skills of apparatus assembly and characterization arts,relying on textbooks and virtual simulation software.Inductive questions in experimental operation stage include observation notes in operations and insitu imagination of knowledge,relying on operation skills and hard practice in lab.Inductive questions in review stage include data analysis guide,recognized knowledge points and improved experimental skills.Question-inductive teaching mode introduces a linking bridge between polymeric theoretical and experimental courses,helps the students to finish experiments better by the assistance of theoretical course,and makes the students understand the associated knowledge deeper in the proficient experiment operations.
