一、充分发挥实验的直观作用对于抽象理论的教授,实验无疑是一种很好的方法。比如在教授“放热反应”“、吸热反应”时,最好的方法就是做好书上的两个实验,让学生亲身体验一下温度的改变,相信他们对于这两个概念的印象必然印象深刻。再比如教授质量守恒定律时,与其引章摘句地说 First, give full play to the intuitive role of experiments For the professor of abstract theory, the experiment is undoubtedly a good method. For example, when teaching “exoergic reactions” and “endothermic reactions”, the best method is to do two experiments in the book so that students can experience changes in temperature. I believe that they have an impression of the impression of these two concepts. profound. For example, when teaching the law of conservation of mass, it is said in its quotation.
