中学化学实验教学的基本形式有四种,即:演示实验、学生分组实验、边教边实验以及课外实验。一、演示实验演示实验是教师结合化学教学内容,在课堂上进行的示范实验。通过演示实验,可以指导学生观察和分析化学现象,使学生获得生动的感性认识,从而加深对化学概念的理解,更好地掌握化学定律。同时,它还能更好地集中学生
There are four basic forms of chemistry experiment teaching in middle school: demonstration experiment, student group experiment, edge experiment and extracurricular experiment. First, the demonstration experiment demonstration experiment is a combination of chemistry teaching content teachers in the classroom demonstration experiments. By demonstrating experiments, students can be guided to observe and analyze chemical phenomena so that students can acquire vivid and perceptual knowledge so as to deepen their understanding of chemical concepts and better understand the laws of chemistry.
