背影
shadow

《背影》
《view of the back》

以小组为单位，每个小组就某一个话题或情形进行讨论的时候，我们能够在屏幕上观察到其他同学的反应和表情，这是传统课堂模式做不到的，因为你的周围都是你的同学，有时候你看到的只是他们的背影。
in small groups, when each group discusses a certain topic or situation, we can observe the reactions and expressions of other students on the screen, which is not possible in the traditional classroom model, because you are all around you classmates, sometimes all you see is their back.
