学生实验课是化学学科教学的重要组成部分,实验课前引导学生做好预习准备,实验课上有效指导和监管学生的实验操作,及时对学生实验过程实施评价,实验课后组织学生进行有效学习反刍,把握好学生实验课堂环节对提高学生实验教学效率大有裨益。 The experimental course of students is an important part of the teaching of chemistry. Before the experiment, the students are guided to prepare for the experiment. The experimental class effectively instructs and supervises the experimental operation of the students, evaluates the experimental process in time and organizes effective learning after the experimental class Ruminating, grasp the experimental aspects of students in experimental teaching to improve the efficiency of great benefit.
