新课程标准的实施,使高中生物教材中的实验数量大为增加,实验教学已经成为生物学科教学内容的一个重要组成部分。因此,确保每一个生物实验在教学中的成功开展,对于保证实验教学的整体教学质量和教学效果具有决定性的作用,对于提高生物学科的教学质量和教学效果也具有重要的意义。不可否认,高中生物教材中的少数实验,在实验方案的设计、实验材料的选择、实验试剂的使用和实验操作方法的应用等方面还存在一些缺陷,这直接影响
The implementation of new curriculum standards has greatly increased the number of experiments in high school biology textbooks. Experimental teaching has become an important part of the teaching content of biology. Therefore, to ensure the successful implementation of each biological experiment in teaching has a decisive role in ensuring the overall teaching quality and teaching effect of experimental teaching, and it is also of great significance for improving the teaching quality and teaching effect of biology. It is undeniable that there are still a few defects in the design of experimental programs, the selection of experimental materials, the use of experimental reagents, and the application of experimental methods in the few experiments in high school biology textbooks. This has a direct impact.
