楞次定律是电磁感应规律的重要组成部分,涉及的物理量多,关系复杂,是教学的难点。在这节教学中,传统的讲授式教学已被探究式实验教学取代,但是目前的探究却只提供特定实验仪器,要求学生在特定的时间内完成探究任务,得到结果,这是真正的探究吗?能体现以学生发展为重,能让学生亲身经历和充分体验科学探究过程吗?这些实验仪器只能组装成教师预设好的实验,其本质仍是教师的强势引导,引诱学生走上教师安排的教学程序中。预定
Lenz’s law is an important part of the electromagnetic induction law. It involves many physical quantities and complex relationships. It is a difficult teaching point. In this section of teaching, traditional lecture-style teaching has been replaced by inquiry-based experimental teaching. However, the current inquiry only provides specific experimental instruments. Students are required to complete the inquiry task within a certain period of time and obtain results. Is this the real inquiry? Can students embody the importance of development and allow students to experience and fully experience the process of scientific inquiry? These experimental instruments can only be assembled into experiments that are pre-programmed by teachers. The essence of these experimental instruments is still the strong guidance of teachers, which induces students to embark on teachers. Arranged in the teaching program. Reservation
