“对比实验+现象驱动的知识挖掘”在高分子材料合成创新实验教学中的尝试与运用

The Trial and Application of “Comparative Experiment and Phenomenon-Driven Knowledge Mining” in Polymer Materials Synthesis Innovation Experiment

高分子材料合成实验是高分子专业的核心实验课程之一,如何建立实验课程与理论课程的有效衔接,加深学生对所学知识点的深入理解和活学活用,是本课程的主要目标。为此,笔者和教学团队提出:在同一个实验中改变某个实验变量,在教学班中引入对比实验,通过这些改变引起的不同实验现象和由此产生的材料性能的迥然差异,引导学生从现象出发,联系理论课堂知识进行深入分析。这种尝试有效改变了以往实验教学中所有教学班千篇一律的操作和几乎完全相同的实验现象与结果,有效激发了学生的主动性,提高了其分析问题、解决问题的能力。2年的实验教学反馈表明,"对比实验的引入"和"现象驱动的知识挖掘"帮助学生有效巩固了理论课堂的知识点,做到了活学活用。

Polymer materials synthesis experiment is the core experimental course of polymer program.How to establish an effective link between experimental course and theoretical course,and deepen students’understanding of the knowledge points they have learned and make full use of them are the main objectives of this course.For this sake,the author and the teaching team proposed:introduce comparative experiments in the teaching class by changing experimental parameter in the same experiment.To understand the different experimental phenomena and material performance differences caused by these changes,we guide students to carefully observe the phenomenon and use knowledge in theoretical course to analysis the mechanism of these phenomena in-depth.This trial has effectively changed the uniform operation and almost identical experimental phenomena and results in the previous experimental teaching course,effectively stimulated the initiative of students,and improved their ability to analyze and solve problems.The feedback of this course during the last two years shows that the introduction of comparative experiment and phenomena-driven knowledge mining have effectively consolidated the knowledge points of theoretical classroom and made it possible for students to creatively study and apply.
