很多中学教师,都会发现一个现象,即课堂上主动举手发言的学生相对比较少。根据相关的社会调查发现,一个孩子在就读幼儿园和小学时,举手发言是很积极的,面对教师的提问,他们是很乐于思考,并主动发言的,可到了中学后,他们主动举手回答问题的行为却几乎消失殆尽。针对这种现象,我把它形象地比喻为“森林→稀树草原→荒漠”。 Many middle school teachers will find a phenomenon in which students in the classroom who raise their hands to speak are relatively few. According to relevant social investigations, it is found that when a child attends a kindergarten or elementary school, he or she raises his hand to speak. It is very positive. Facing the teacher’s question, they are very willing to think and take the initiative to speak. When they reach secondary school, they actively raise their hands. The act of answering questions has almost disappeared. In response to this phenomenon, I have compared it vividly to “forest → savannah → desert”.
