思想实验和唯物辩证法在乙酰苯胺重结晶实验中的教学探索

Teaching Efforts via Combining Thought Experiment and Materialist Dialectics in Acetanilide Recrystallization

以乙酰苯胺重结晶实验为例,在学生的课前预习中引入思想实验,通过翻转课堂中设计的递进式问题讨论,引导学生利用唯物辩证法的方法进行思想实验,带领学生深入思考实验过程,从而在实际操作中避免易犯的失误,取得了良好的教学效果。

Taking the recrystallization of acetanilide as an example, we introduce thought experiment into students’ preview. By discussing the progressive problems designed in flipped class, we guide students to use materialist dialectics to carry out thought experiment and help them to think thoroughly before they do. Hence students might avoid common mistakes when they practice. These teaching efforts achieve positive results.
