在高中生物教学中,演示实验既是生物教学活动的重要组成部分,又是开展生物教学活动的重要手段,因此,重视演示实验,努力提高演示实验的质量是一个非常重要的问题。在本文中,笔者论述了在高中生物课堂上开展演示实验需要注意的问题,希望能够为生物课堂教学质量的提升提供一些参考。
In high school biology teaching, demonstration experiment is not only an important part of biological teaching activity, but also an important means to carry out biological teaching activities. Therefore, it is a very important issue to emphasize demonstration experiment and improve the quality of demonstration experiment. In this paper, the author discusses the problems that need to be paid attention to when demonstrating experiment in senior high school biology class, hoping to provide some references for improving biology teaching quality.
