本文以中职物理教学中的重要内容“变压器与交流输电原理”这一教学主题为例,从演示实验的视角,侧重于演示实验的设计和实效性的探究,希望能给读者带来一定的帮助。一、准确定位演示实验达到的教学目标准确定位演示实验达到的教学目标,是在教学前完成实验过程设计,实验设计在教学中实施的出发点是精准把握教学过程的基础。在中职物理教学内容“变压器与交流输电原理”中,需要学生通过学习掌握的目标主要是:通过这个实验激发学生了解电磁感应
Taking the teaching content of “Transformer and AC Transmission Principle” as an example, from the perspective of demonstration experiment, this dissertation focuses on the design of experimental demonstration and practicality, hoping to bring readers Some help. First, to accurately locate the teaching objectives of the demonstration experiment Accurate positioning of the demonstration experiment to achieve the teaching goal is to complete the experiment before the teaching process design, experimental design in the teaching of the implementation of the starting point is to accurately grasp the basis of the teaching process. Physics teaching in secondary vocational teaching content “Transformer and AC transmission principle ”, need students to master the main goal is: Through this experiment to stimulate students to understand the electromagnetic induction
