中学生物课的教学离不开实验。学生通过亲自动手做实验，才能真正理解和掌握所学的知识。实验既锻炼了学生的动手能力，又训练了其观察、分析和解决问题的综合能力。近年来，我们在普及生物实验教学，提高学生实验素质方面做了一些尝试。一、注重运用“讲”“做”结合实验法，? The teaching of biology classes in middle school is inseparable from experimentation. Students can truly understand and master what they have learned by experimenting with their own hands. Experiments not only exercised students’ hands-on abilities, but also trained their comprehensive ability to observe, analyze, and solve problems. In recent years, we have made some attempts to popularize biological experiment teaching and improve students’ experimental quality. First, pay attention to the use of “speaking” and “doing” in combination with experimental methods.
