演示实验是教师在课堂上结合教学内容做的演示给学生看的实验。它在物理教学特别是初中物理教学中具有十分重要的作用。一、初中生的心理特点和物理的学科特点决定了物理教学中必须加强演示实验教学初中学生思维正处于具体形象思维向抽象逻辑思维过渡的阶段,其中形象思维仍起重要作用,抽象思维正在发展。在很大程度上,学生仍习惯于靠经验材料判断分析事物,不善于从
Demonstration experiment is a demonstration that the teacher sees to students in the classroom with the teaching content. It plays an important role in physics teaching, especially junior high school physics teaching. First, the psychological characteristics of junior high school students and the characteristics of physics determine the physics teaching must strengthen the experimental teaching of junior high school students thinking is in the concrete image of thinking to the transition of abstract logical thinking stage, in which image thinking still plays an important role in abstract thinking is developing . For the most part, students are still accustomed to judging things based on empirical material and not good at them
