实验是物理的灵魂,演示实验是最高效的物理实验教学策略。电势差这一知识点概念性强、抽象、理解难度大,又是高考的重点,教材中对这一知识点没有编排演示实验,使得电势差的教学成为教师课堂教学中的“难题”。本文通过高效精彩的演示实验,将抽象的电势差概念具体形象化,赋予枯燥难懂的电势差灵性,打破以往“灌输式”的教学模式,开创了电势差教学的新思路。
Experiment is the soul of physics. Demonstration experiment is the most effective physics experiment teaching strategy. The potential difference is a concept that is strong, abstract, and difficult to understand. It is also the focus of the college entrance examination. There are no demonstration experiments on this knowledge point in the teaching materials, making the teaching of potential difference a “problem” in the classroom teaching. This article through efficient and wonderful demonstration experiment, concretely visualizes the abstract concept of potential difference, gives boring and difficult to understand the potential difference spirituality, breaking the previous “indoctrination” teaching mode, creating a new idea of potential difference teaching.
