新课程改革一直强调:初中物理课程旨在提高学生的科学素养,让学生养成良好的思维习惯,在分析问题和解决问题时尝试运用科学知识和科学实验方法。物理课堂中的实验分为两种:一种是教师做的演示实验,就是教师在讲台上操作实验,学生在下边观看;另一种就是学生在实验室根据实验原理亲自操作的实验。无论哪种实验,都需要教师和学生认真研究和准备,在这个过程中,教师和学生都要明白我们不是为做实验而做实验,我们做实验 The new curriculum reform has always stressed: junior high school physics curriculum aims to improve students’ scientific literacy so that students develop good thinking habits, try to apply scientific knowledge and scientific experiment methods in analyzing and solving problems. There are two kinds of experiments in the physics class: one is a demonstration experiment done by the teacher, that is, a teacher operates an experiment on the podium and the student watches from below; and the other is an experiment in which a student hands himself in the laboratory according to the experimental principle. No matter what kind of experiment, teachers and students need careful study and preparation, in the process, teachers and students must understand that we are not doing experiments for experiments, we do experiments
