物理教学,不仅要使学生掌握系统的理论知识,而且要运用理论解决实际问题。实验课正是理论联系实际,培养学生解决实际问题能力的重要环节。因而实验在物理教学中占有重要的地位。但过去我系有很多师生是不重视实验的,在实验内容和方法方面存在不少问题。 1.脱离生产脱离实际,为实验而实验。过去实验绝大部分是验证性的,从不考虑如何与生产实际相联系,定量性的实验也不考虑它与生产的关系。例如测定粘滞系数、表面张力、液体的比热等用的机油、酒精、松节油、煤油,究竟这些物理量的测定与生产有什么关系,大家都不知道;高电阻的测定用的是1MΩ瘤的碳质电阻,电容的测定用的是标准电容,测电感用的是螺线管,都和当
Physics teaching, not only to enable students to master the theoretical knowledge of the system, but also to use theory to solve practical problems. The experimental class is an important part of integrating theory with practice and cultivating students’ abilities to solve practical problems. Therefore, experiment occupies an important position in physics teaching. However, in the past, many teachers and students in our department did not attach importance to the experiment. There are many problems in the contents and methods of experiment. 1. Out of production from the actual experiment for the experiment. Most experiments in the past were verifiable, never considering how to relate to the actual production, and quantitative experiments did not consider its relation to production. For example, the determination of viscosity, surface tension, the liquid used for the specific heat of oil, alcohol, turpentine, kerosene, after all, the determination of these physical quantities and production have anything to do, we do not know; the determination of high resistance 1MΩ tumor Carbonaceous resistance, capacitance measurement is the use of standard capacitors, inductors are used to measure the solenoid, both and when
