如何讲究教学方法呢 ?我们不妨先看一下某中学优秀教师 ,对初中生物学“鲫鱼”一节中 ,关于鲫鱼的呼吸、鳍及鳔的作用等知识是如何进行教学的。关于鲫鱼呼吸的知识 ,先是提出有关问题让学生进行思考。然后学生分组实验 :在甲、乙 (盛有清水 )、丙 (盛有烧沸几分钟后冷却的水 )?
How to stress teaching methods? We might as well look at the teaching of a high school teacher in the junior high school biology “squid” section on how the eel’s breathing, fins, and fleas function. With regard to the knowledge of squid respiration, first ask relevant questions for students to think about. Then the student group experiment: in A, B (with clear water), C (having water cooled after a few minutes of boiling)?
