学生学习化学是从实验观察开始的，要想使观察达到良好的效果，关键在于必须掌握科学的观察方法。下面拟就此问题谈点个人体会。一、协同观察法即调动学生尽可能利用多种感官协同观察从初中第一个化学演示实验开始，教师就应注意调动学生充分利用视觉、听觉、嗅觉和触角等多种 Students learn about chemistry by starting with experimental observations. The key to achieving good results in observations lies in the need to master scientific observation methods. The following is to discuss personal experience on this issue. First, the collaborative observation method that mobilizes students to use a variety of sensory collaborative observation as much as possible from the first chemical demonstration experiment in junior high school, teachers should pay attention to mobilize students to make full use of visual, auditory, sense of smell and tentacles and other
