学生在学习电磁振荡的有关知识时 ,由于思维定势 ,往往利用有关稳恒电流的知识去理解和解释振荡电路的问题 ,从而得出错误的结论和认识 .为了解决这个问题 ,教师在教学过程中 ,一方面可以利用图像及斜率的有关知识 ,去帮助学生提高应用图像分析问题、解决问题的能力 ,达到克服 When students learn the electromagnetic oscillation knowledge, they often use the knowledge of steady current to understand and interpret the problems of the oscillation circuit when they learn about electromagnetic oscillations, so as to draw wrong conclusions and understandings. In order to solve this problem, teachers are in the teaching process. On the one hand, you can use the knowledge of images and slopes to help students improve their ability to apply image analysis problems and solve problems.
