我们在生物教学中加强第二课堂教学活动，取得了一定的收获。现谈谈我们的体会。1．结合教材内容开展实验活动第二课堂活动一开始，我们便先让兴趣小组成员练习使用显微镜，制作临时和永久装片。这是因为学生在中学的几年中，生物实验做得较少，任课老师很难在短短的四十五分钟 We strengthened secondary classroom teaching activities in biology teaching and achieved certain gains. Let’s talk about our experience. 1. Combine the content of the teaching materials to carry out the experiment activities At the beginning of the second classroom activity, we first let the members of the interest group practice using the microscope to make temporary and permanent films. This is because students have had fewer biological experiments in the middle school years, and it is very difficult for teachers to take a short period of forty-five minutes.
