【Abstract】 The continuous reform of the new curriculum teaching standards has made people realize that the cultivation of students' abilities is the main task in the teaching process, and teaching should not be done for the sake of teaching. It is necessary to proceed from reality, respect the subjective wishes of students, and understand their ideas. "Electromagnetic induction" is an important part of the "magnetism" of senior high school physics. The learning of this part of knowledge will test students' comprehension ability. Teachers should pay attention to students' hands-on operation ability and let students actively participate in the learning process. This article discusses the learning method of electromagnetic induction from multiple angles, and analyzes it in combination with practical examples.

物理是理科综合中的重要组成部分,在高考中占据重要地位。物理是一门注重实际操作的学科,人类在发展的历史上,总结出了一些物体变化规律,这些规律又指导着人们的生产实践活动,有效推动着科学和社会的进步。因为物理当中有很多实验,所以教师的教学方法直观性一定要强,这样才能和实验更好地联系起来。教师要把工作重心放在培养学生的动手能力上,提高他们分析问题和解决问题的能力。任何知识都有侧重点,教师一定要牢牢把握重点知识,帮助同学们打牢基础,磁场和电场有相似之处,可以把二者放在一块学习,方便大家理解。
一、培养学生的动手能力
电磁感应这部分知识的课堂教学环节中,教师要尽量用实验器材给同学们教学,这样大家才能直观地感受磁场的作用和分布,对电磁感应的认知才会更加深刻。物理本来就是以抽象的理论为主,教师不加以引导的话,同学们很容易因为理解能力较弱而跟不上学习的进度。……
