21世纪是生物世纪,生物科学对人类社会影响之巨大将不可预料。为适应这种形式的发展,生物教师必须树立教学新理念,摒弃陈旧的教学思想和教学方法,倡导探究性学习,自主学习和合作学习,努力改变学生的学习方式,改进生物实验,启迪学生思维,引导学生质疑,培养学生的创新精神和实践能力。高中教材中所提供的材料、方法、操作过程做实验,多数是可以取得好效果的,但也有些实验往往也存在一些美中不足,所以尝试新的实验方法可以消除原实验中的弊端。
The 21st century is the century of biology. The enormous impact of biological science on human society will be unpredictable. In order to adapt to this form of development, biology teachers must establish new teaching concepts, abandon outdated teaching thoughts and teaching methods, advocate exploratory learning, self-study and cooperative learning, strive to change students ’learning styles, improve biological experiments and enlighten students’ thinking , Guide students to question and cultivate students’ innovative spirit and practical ability. Most of the materials, methods and operating procedures provided in the high school teaching materials are effective. However, some experiments often have some drawbacks. Therefore, trying out new experimental methods can eliminate the disadvantages in the original experiment.
