高一必修1 第五模块

《实验室里的一节课》，可以说是本册书中的难点。因为和化学实验有关系，所以难免涉及一些化学方面的单词。这对于我们普高本就英语基础薄弱的学生而言，学习起来并不是那么简单。为了让学生以饱满的态度积极的学习本单元的内容，这部分，我用的时间超过以往，通过让学生多多学习和联系英语五种数字的读法以及最后给出图片和视频，让他们对下一节课有了一些期盼。同时在课堂上的数字练***部分的学生张开了嘴，激发了他们的自信心，让他们有所得，为今后的英语学习奠定了情感基础。

优点

：

课堂活跃，全员参加。

条理清楚，讲练结合。

合理利用板书和幻灯片，重难点突出。

不足： 时间上有些不足，有个游戏没有充分完成。
