一位外国教师说,如果学生“不乱”,要先有本事让他们“乱”起来,然后又有本事让他们“不乱”。孔子说:“不愤不启,不悱不发。”中外说法虽异,道理却同:教学中的“不乱”,其实是一种思维的惰性,而打破这种状态,就有赖于寻找矛盾并且利用矛盾。 A foreign teacher said that if students “do not mess up,” they must first have the ability to “disrupt” them, and then have the ability to let them “do not mess.” Confucius said: “I don’t feel indignant or involuntary.” Although the Chinese and foreign arguments are different, the reasoning is the same: “indiscriminately” in teaching is in fact a kind of inertness of thinking, and breaking this state depends on finding Contradictions and use contradictions.
