教学方法的改革必须服从学生的可接受性原则,也就是说一切从学生实际出发,讲解深入浅出,学生容易接受,做到学以致用。实验课教学方法的改革也必须遵循这个原则。实验课的教学目的,是培养学生的实验能力,其中包括对仪器的认识、操作,对现象的观察,对数据的处理等,要想完成上述教学目的,教师讲解必须通俗,操作步骤要便于学生记忆;时间分配必须得当,以保证学生有充分操作机会。我沿着这个思想方法谈一下“关于高二物理学生实验《练习使用示波器》教学方法改革的探索”。根据物理教材的要求,《练习使用示波器》实验项目有两个:①学生会利用示波器调试出交流电压信号——正弦波形;②学生会利用示波器测试直流电压。可是根
The reform of teaching methods must obey the student’s principle of acceptability, which means that everything starts from the students’ reality and explains the profound things in a simple way. The students are easy to accept and apply what they learn. The reform of experimental teaching methods must also follow this principle. The teaching purpose of the experiment class is to cultivate students’ experimental abilities, including the knowledge and operation of the instrument, the observation of phenomena, and the processing of data. In order to accomplish the above teaching objectives, the teacher’s explanation must be popular, and the operation steps should be easy for students. Memory; Time allocation must be done properly to ensure that students have full operational opportunities. I went along this ideological approach to talk about the “exploration of the reform of teaching methods for practicing oscilloscope exercises in the high school physics student experiment.” According to the requirements of physics textbooks, there are two experimental projects for “practical use of oscilloscopes”: 1 Students will use the oscilloscope to debug AC voltage signals—sinusoidal waveforms; 2 Students will use the oscilloscope to test DC voltage.
