摘要
预习教学是指导学生自主学习实验技能,理解实验原理的重要一环。目前,多数学校现行的预习教学侧重于机械地讲解实验操作步骤,教学方式多为要求抄写实验指导书,教学实际效果较差,教师和学生付出许多时间却收获甚微。文中主要通过分析现有预习教学方式的问题,提出预习内容分层次,分阶段进行的概念。实际教学实验验证了此种教学方式的可行性及相应效果。
Preview teaching is one of the very important steps to guide students to learn experiment skills and understand the experiment principles autonomously. The preview experiment teaching practiced in many schools focuses on the stiff explanations of the operation procedures. Most of the teaching forms are requiring students to copy the guidebooks of experiment. This kind of teaching method has a poor actual effect while both teachers and students paid a lot but got little. This paper mainly based on the analysis of the problems oc- curred on the existing method, come up with the concept of hierarchical and grading on preview teaching. The results prove the feasibil- ity and effect of this kind of teaching method by actual teaching experiment.
