目前物理教学中存在不重视实验,不重视动手实验的倾向,加大了实验试题的难度,使实验题的平均得分率每年都比较低.考生常见的错误有如下几种: 1 没有真正理解实验的原理和方法。 要真正理解实验的原理和方法,就应清楚地知道为达到实验的目的,需要证明什么问题,测量什么物理量.知道进行证明或测量的依据,了解测量的方法.掌
At present, physics teaching does not pay attention to experiments, does not attach importance to hands-on experiments, increasing the difficulty of the experimental test questions, so that the average test scores are lower each year. Candidates common mistakes are as follows: 1 did not really understand the experiment The principles and methods. To truly understand the principles and methods of experimentation, it should be clearly known what problems need to be demonstrated and what physical quantities to measure in order to achieve the purpose of the experiment. Know the basis for the proof or measurement, and understand the method of measurement.
