我从事教育工作30多年,任过教师、教导主任、校长,听过几百节课,也评过不少课。曾为不少课拍手叫好,也曾对一些课摇头皱眉。按理说,预先通知、有充裕时间作准备的课,应该比不提前通知、直接“推门”听的课质量好。然而,最差的课、最令人“倒胃口”的课有时偏偏就是“准备充分” I have worked in education for more than 30 years. I have served as a teacher, teaching director, principal, heard hundreds of classes, and also reviewed many lessons. I was applauded by many class clappers, and I have also shaken my head in some classes. It stands to reason that a class that has been notified in advance and has ample time for preparation should be of better quality than a class that does not advance notice or directly “push the door”. However, the worst lesson and the most “inappropriate” lesson are sometimes “preparatory”
