案例:区教研员周五将来我校进行集体视导工作,老师们为准备接受听课进行着紧张的准备。周一下午有位老师来找我调班:“校长,视导那天能不能让我用(1)班讲课,(2)班的学生太差。”确实,我们常会遇到这样的现象:每当有教师要做课的时候,他们往往会挑选自己心目中的“好班”来讲课, Case: The district teacher and researcher will conduct collective visual guidance work on Friday in our school. The teachers are preparing for the preparation for the lecture. On Monday afternoon, a teacher came to me and asked me to change classes: “The principal, if he can’t let me use class (1) to teach classes that day, and class (2) students are bad.” Indeed, we often encounter this phenomenon: When teachers have classes, they often pick their own “good classes” to teach.
