一说起“上课”,人们就会想起这样的情景:教师站在讲台前,对学生传道、授业、解惑,学生们则横竖成行,正襟危坐,一律面向老师听讲、做作业。沿袭已久的这种教学模式虽然便于教师控制全班学生的课堂行为,却极不利于学生之间的课堂交往。全班几十个学生尽管在同一个班级、同一间教室里“同学”,但由于相互之间无法广泛地沟通思想、互相帮助,因此实际上是在“独学”, When it comes to “class”, people will think of such situations: teachers stand in front of the podium, preach to students, give their jobs, and confuse them. The students will go all out and sit tight and listen to their lectures and homework. Although this teaching mode has been followed for a long time, it is very convenient for teachers to control the classroom behavior of the whole class of students, but it is very detrimental to the classroom communication between students. Although tens of students in the same class and “classmates” in the same classroom do not have the ability to communicate widely with each other and help each other, they are in fact “single-parent”
