传统的实验课程序是:由实验员和教师把仪器、药品准备齐全,教师讲解实验原理,操作步骤、注意事项,演示操作,然后让学生动手做实验。这样的程序有其优点,即实验课比较容易组织,进行较顺利,但是它的明显缺点是学生依赖性强,处于被动状态,对培养学生独立思考和工作能力是不利的。为了变被动为主动,调动学生的积极性,除了采用传统的实验教学外,还应该让学生运用系列的知识和技能自行设计一些带有创造性的实验,发展学生的创造思维能力。
The traditional experiment course is: the laboratory staff and teachers to prepare equipment, medicines, teachers explain the principles of the experiment, steps, precautions, demonstration operation, and then let the students do experiments. Such programs have the advantage that the experimental class is relatively easy to organize and run smoothly, but its obvious disadvantage is that the students are highly dependent and passive, which is unfavorable for cultivating students’ independent thinking and working ability. In order to be passive and initiative, to mobilize the enthusiasm of students, in addition to using traditional experimental teaching, students should also use a series of knowledge and skills to design some creative experiments to develop students’ creative thinking ability.
