电学实验是每年高考的重头戏.特别是伏安法测电阻的实验,不但老师教起来难,学生也往往在课堂上束手无策,再加上学生的能力不同,表现出来的课堂学习行为差异也很明显,本人通过教学实践探索,研究学生课堂学习行为差异的分类互动教学策略,不但改变了绝大部分学生对电学实验的畏惧心理,还让学生的实验能力和自信有了显著的改善. Electrical experiment is the highlight of the annual college entrance examination.Especially the voltammetry resistance measurement experiment, not only the teacher taught it difficult, students are often in the classroom helpless, coupled with the different abilities of students, showing differences in classroom learning behavior is also obvious , I explored through teaching practice and studied the interactive teaching strategies of classifying students ’differences in classroom learning behavior. This not only changed the vast majority of students’ fear of electrical experiments, but also significantly improved their experimental abilities and self-confidence.
