1.生物实验的特点。一是具有较强的探索性和可塑性。在进行实验教学时,我们不能照本宣科,按部就班地进行,在传授学生一些基本技能技巧的基础上应鼓励学生在实验过程中积极地改造、探索。二是具有较强的严谨性和逻辑性。在做探索淀粉酶对淀粉和蔗糖的作用实验时,许多学生易把药品搞混淆,原因是在取淀粉液和蔗糖液时,把用过 1. The characteristics of biological experiments. The first is strong exploratory and malleable. When we conduct experimental teaching, we cannot follow the text and follow the steps. We must encourage students to actively reform and explore during the experiment process based on the students’ basic skills and skills. The second is that it has strong rigor and logic. When doing experiments on the role of amylase in starch and sucrose, many students were confused about the drug because the starch solution and sucrose solution were used.
