生物的呼吸作用,在高中生物教材中是难度较大的一部份内容,特别是有氧呼吸的过程。教材中提到有氧呼吸分三个步骤,提示了有氧呼吸的基本过程,但教材叙述很简略仅有七行字,这使学生很难理解。为讲清教材内容现谈谈对“呼吸作用”一节的教学尝试。一、有氧呼吸 Biological respiration is a more difficult part of high school biology textbooks, especially the process of aerobic respiration. The reference to aerobic respiration in the teaching materials is divided into three steps, suggesting the basic process of aerobic respiration. However, the teaching material is very simple and has only seven lines, which makes it difficult for students to understand. In order to clarify the content of the teaching materials, we now turn our attention to the teaching experiment on the “Respiration” section. First, aerobic respiration
