从教学法的角度对(a～1)/m图象谈几点看法物理学是一门以实验为基础的学科,因此在物理教学中必须广泛应用实验。中学物理实验(包括演示实验与学生实验)又是一种最积极的学习方式,是发展学生智力、培养学生能力必不可少的教学环节。在实验过程中能培养学生对物理现象的观察能力,掌握仪器的使用,学会测量和处理数据等,以使学生得到独立实验的初步素养,因而实验的设计和编排除紧扣教学内容以外,还要考虑满足上述的要求,然而现行高中物理教材中有些实验是有欠缺的,现仪以(a～1)/m图象的实验为例,提出几点意见。
From the perspective of the pedagogical approach, I would like to make a few observations about (a ~ 1)/m images. Physics is an experiment-based discipline. Therefore, it must be widely applied in physics teaching. High school physics experiments (including demo experiments and student experiments) are also the most active learning methods. They are an indispensable teaching link for developing students’ intelligence and cultivating their abilities. In the experiment process, students’ ability to observe physical phenomena can be cultivated, the use of the instrument can be mastered, and the measurement and processing of data can be learned so that the students can get an initial literacy of independent experiments. Therefore, the design and compilation of experiments excludes the contents of the teaching. We must consider meeting the above requirements. However, some of the current high school physics textbooks are lacking in experiments. Take the experiment of (a ~ 1)/m image as an example and put forward some opinions.
