【案例介绍】高二按照正常的进度,理科班将上完选修3-1后,直接进入选修3-2的学习。所以,在期中考试之前已开始准备《楞次定律》,按照以往的惯例,这节课打算应用分组实验,由学生实验得出楞次定律的基本概念,并逐步指导他们处理相关问题。一直以来,我觉得这是很好的教学方式,所以,这次我也照旧处理了。因为《楞次定律》实验过程并不复杂,所以在正常引入介绍
【Case Introduction】 In accordance with the normal progress of the second year, the science class will directly enter the elective 3-2 after finishing the elective 3-1. Therefore, before the mid-term exam, we have begun to prepare the “Leng’s Law”. In accordance with past practice, this lesson intends to apply grouping experiments. The students experiment to arrive at the basic concepts of Lenz’s law and guide them step by step to deal with relevant issues. For a long time, I think this is a very good teaching method, so this time I still deal with it. Because the experimental procedure of Lenz’s Law is not complicated, it is introduced normally.
