电场强度、电势、电容是静电学中三个重要的基本概念,其中电势既是本章教材的重点和关键,又是本章的难点.为了帮助学生尽快掌握静电学知识,我以电势为突破口,在电势教学中抓住以下三个环节. 1 运用类比法、化抽象为具体. 类比是沟通新旧知识的桥梁,是培养学生科学思维能力的有效手段之一,在教学中适时而恰当地运用类比,常可化抽象为具体,在复习旧知识中教学新内容,使新知识既有“似曾相识”的亲切感,又觉得新鲜,
Electric field strength, electric potential, and capacitance are three important basic concepts in electrostatics. The electric potential is the key and key to this chapter’s teaching material, and it is also a difficult point in this chapter. In order to help students master the knowledge of electrostatics as soon as possible, I use the electric potential as a breakthrough point in the electric potential. The following three steps are taken in teaching: 1. Use analogy and abstraction as concrete. Analogy is the bridge between old and new knowledge, and it is one of the effective means to cultivate students’ scientific thinking ability. It uses appropriate and appropriate analogy in teaching. Can be abstracted as concrete, teaching new content in the review of old knowledge, making the new knowledge both familiar and fresh.
