实验教学是培养学生观察能力的有效途径。初中学生虽然对化学实验充满兴趣,但如果缺少必要的观察指导和观察能力的培养,学生实验往往停留在好玩、热闹的粗浅层次。观察能力的培养也并非一蹴而就,需要教师在化学实验教学的各个阶段循序渐进、积极指导、逐步提高。试举一些案例,阐述在化学实验教学中如何循序渐进,逐步培养学生的观察能力。 Experimental teaching is an effective way to train students' observation ability. Although junior high school students are full of interest in chemistry experiments, the students' experiments tend to stay in a playful, lively and superficial level without the necessary training of observation, observation and observation. The cultivation of observation ability is not accomplished overnight. Teachers are required to gradually and actively guide and gradually improve in all stages of chemistry experiment teaching. Give some examples to illustrate how to proceed step by step in chemistry experiment teaching and gradually develop students' observation ability.
