一节自然课短短40分钟,除了小组讨论,学生发言机会很少。在课堂提问时,有很多同学小手举得高高的,但有机会发言的只能是少数。当他们放下小手,脸上那失望的表情,每每定格在我的脑海里,久久不能抹去。孩子们很喜欢我,往往下课了还围在我的周围,对我诉说有趣的自然现象,提出自己? A section of natural course just 40 minutes, in addition to group discussions, students have very few opportunities to speak. When asked in class, many of my classmates held high hands, but only a few had the chance to speak. When they put down their hands, the expression of disappointment on their faces, often in my mind, a long time can not be erased. Children like me very much, often after class, but also around me, telling me interesting natural phenomena and presenting myself?
