《高分子化学实验》课程交互式教学改革及其效果的调查研究

An Investigation on the Effect of the Interactive Teaching Method in the Course of“Polymer Chemistry Experiment”

《高分子化学实验》课程是高等院校高分子专业本科生学习高分子科学的关键实践环节。实验课内容需与高分子化学课程中理论知识紧密联系的要求决定了实验课内容的基础性和规范性。在规定的教学内容内,培养学生动手能力,激发学生兴趣、培养学生创新思维是本实验课程教学的核心目标。本教学改革通过:(1)在既定教学内容上调节实验变量、增加实验结果未知性;(2)增加实验过程中的教师与学生、学生与学生的交流强度;(3)增加课程的平时成绩权重的成绩评定方法等改善教学效果,并通过问卷调查的形式分析和评价交互式教学效果。本文的措施和结论为高分子化学实验课程的教学提供了有益的参考价值。

＂Polymer chemistry experiment＂ is one of the key courses for studying the knowledge of polymer science for the undergraduates. The experiment contents of this course are required to reflect the main concept and principle of the polymer chemistry course. As a result, the contents of this course should be normative and basic. In this scenario, the teaching goal of this course is to develop students＇ ability and experimental skills, to stimulate the interest of polymer science and motivate innovative thinking. In this report, we studied the teaching effectiveness of the interactive teaching method in this course： 1） vary the conditions of some experiments, and made the results that was different to the standards answer, 2） increase the frequency of the communications between teacher vs. students and students vs. students, 3） change the assessment method of the course for the students, and 4） use a questionnaire for evaluating the teaching effectiveness of interactive classroom teaching method in this course. The results of the questionnaire strongly supported that the interactive teaching method favored the learning of the student in the course. This paper provides a useful reference to the teachers for the course of polymer chemistry experiment.
