古代有一位在南方做官的“北人”,他“席上啖菱,并壳入口”。当有人告诉他“须去壳”时,他自护其短,说“我非不知去壳者,欲以清热也”。从而给后人留下了笑柄。由此联想到当今教学实际中,“啖菱并壳”者亦非鲜见。有些教师读错字、做错题、办错事等等,一旦学生指出来,他们或者绞尽脑汁,为自己辩解;或者以势压人,让学生低头。原因是担心承认错误,会降低自己的威 In ancient times, there was a “Northern man” who served as an official in the south. He “puts on the lining and enters the shell”. When someone told him that he had to “go shell,” he took care of his own short and said, “I do not know shellers, want to heat it.” This left a laughing stock for later generations. This reminds us of the fact that in today’s teaching practice, “Ming Ling and Shell” are not uncommon. Some teachers read the wrong characters, do the wrong things, do wrong things, etc. Once the students point out, they either rack their brains to defend themselves; or press others to lower their heads. The reason is that worrying about admitting mistakes will reduce your own power.
