放手让学生边学边实验,必须遵循因材施教、循序渐进的原则,要设计好边学边实验的阶梯,帮助学生步步深入。既不要使学习的跨度过大,使学生无从入手,又不要使学习的跨度过小,不利于学生的发展。在设计边学边实验的方案时,应注意了解学生实际,对实验中可能出现的问题、可能出现的困难等,都要作充分的估计和准备。
To let students learn while experimenting, we must follow the principle of teaching students according to their aptitude and step by step. We should design a good way to learn the steps and help the students step by step. It is neither necessary to make the span of study too large, to make it impossible for students to start with, and to not make the span of study too small, which is not conducive to the development of students. In the design of the program of learning while studying, we should pay attention to understand the students’ actual problems, possible problems in the experiment, the possible difficulties, etc., should be fully estimated and prepared.
