实验是化学课程的基本特征,化学实验能使课本中抽象的化学知识变成具体的、触手可及的实验现象。就如何上好实验课,调动学生的学习兴趣作了阐述。演示实验必做,有利于对学生进行直观教学;分组实验尽量做,以提高学生学习化学的兴趣;受条件限制无法做的实验可以引导学生“想象”;通过课前预习和课后复习对实验进行掌握。
Experiments are the basic characteristics of chemistry courses. Chemical experiments can make the abstract chemical knowledge in textbooks into concrete and tentative experimental phenomena. On how to do a good experiment, to mobilize students’ interest in learning elaborated. Demonstration experiment must be done, is conducive to the students intuitive teaching; group experiments try to do to improve students’ interest in learning chemistry; subject to conditions can not do experiments can guide students “imagination ”; through pre-class review and after-school review Master the experiment.
