在高中生物学教学中,如何提高实验的随堂完成率和成功率是提高高中生物学教学质量的一个重要举措。而微型实验由于具有实验剂量少、成本低、简约、安全、可控、操作方便、现象明显、减少污染、易于开展等方面的优点在化学实验教学中得到了广泛开展,但在高中生物学实验教学中还
In high school biology teaching, how to improve the completion rate and success rate of the experiment is an important measure to improve the teaching quality of high school biology. Micro experiments have been widely carried out in chemical experiment teaching because of their advantages of less experimental dose, low cost, simplicity, safety, controllability, convenient operation, obvious phenomena, reduction of pollution, and ease of development, but they have been used in high school biology experiments. Teaching also
