采用“让学生评价学生的实验”方法,对设备不全和学生基础较差的公社初中,在培养生学实验能力方面是一种较有效的办法。作法是;实验前,布置实验内容并告诉学生,届时准备先让一个学生在讲台前操作,操作者不准带书本,但可以带预习笔记。其他学生要认真观察:基本操作和装置是否正确?实验步骤是否合理?实验现象及效果是否明显?
Adopting the method of “let students evaluate students’ experiments” is a more effective method for cultivating experimental ability in the commune junior middle school with incomplete equipment and poor student foundation. The practice is; before the experiment, the contents of the experiment are arranged and told to the students that when they are ready to let a student to operate in front of the podium, the operator is not allowed to bring books, but can take notes. Other students should carefully observe: are the basic operations and devices correct, and are the experimental steps reasonable? Are the experimental phenomena and effects evident?
