让学生真正做好实验预习

本文认为实验指导教师实验前板书过于详细，甚至给学生做演示实验，以及实验时几个学生一小组，使得大部分学生懒得做实验预习。如果实验前为学生提供一些必要的资料和说明书，实验时教师讲解不要过于详细，尽量为学生创造独立完成实验的条件，可以促使学生认真做好实验预习。

Let the Students Really Do Well in Experiment Preparation

The article considers that most of the students become lazy inpreparing for the experiment. while the teacher write on the blackboard over details before the experiment, he even displays the experiment for the students and makes several students be in a group. The students will do good preparation for the experiment if some essential materials and introduction for the students are provided before the experiment and in the experiment the teacher doesn`t explain too details but tries his best to creat the condition for the students to complete the experiment independently.
