在教学实践中，我根据具体情况将部分教材中较难理解的内容在课外科技活动时间补充生物课外实验，发现这一举措不仅能培养学生的学习兴趣、提高学生动手动脑的能力，而且对生物学课堂教学也有很大的推动和促进作用。现举例如下：在“动物体内的物质运输”的“蝗虫的血液循环” In the teaching practice, I supplemented the biological extracurricular experiments with extra-comprehensive content in extracurricular science and technology activities according to specific circumstances. I found that this measure can not only cultivate students’ interest in learning, but also improve the students’ ability to use hands-on brains, and to the biology. Learning classroom teaching also has great promotion and promotion. Examples are as follows: “Aphid’s Blood Circulation” in “Material Transport in Animals”
