兴趣是学生最好的老师,一成不变的教学方法只会让学生厌倦,最终丧失学习的动力。以下是我的几点体会:一、巧用比喻化疑难。细胞膜的结构像花生糕:花生米像蛋白质分子,爆米花像磷脂分子,花生米以不同的深度覆盖、镶嵌或贯穿于其中。糖类和ATP比喻成家里的粮食和口袋里的现金。高温和低温对酶的影响比喻成人死了和睡着了。二、妙用诗词添兴趣。例如,物质出入细胞膜

Interest is the best teacher of the student, the rigid teaching method will only make the student tired, eventually lose the motivation of study. The following is my experience: First, clever use of analogy difficult. The structure of the cell membrane like peanut cake: peanuts like protein molecules, popcorn like phospholipid molecules, peanuts covered with different depths, inlaid or through them. Sugar and ATP metaphor into home food and pocket cash. The effects of high and low temperatures on the enzyme metaphor adult death and asleep. Second, magic poetry add interest. For example, substances enter and leave the cell membrane
