二十世纪70年代,美国气象学家洛伦兹在解释空气系统理论时提出:亚马逊热带雨林一只蝴蝶翅膀的偶然振动,两周后也许就会引起美国得克萨斯州的一场龙卷风,这叫作“蝴蝶效应”。也就是说,在同一个动力系统中,初始条件下微小的变化能带动整个系统长期的巨大的连锁反应。有趣的是,在“全课程”的课堂教学中,这种蝴蝶效应也往往会被印证。“全课程”对我最大的改变,就是让我明白了“老师一定要学会放 In the 1970s, American meteorologist Lorentz, in explaining the theory of the air system, proposed that the accidental vibration of a butterfly’s wing in the Amazon rainforest might cause a tornado in Texas two weeks later, which is called ”The Butterfly Effect“. In other words, in the same dynamical system, slight changes under the initial conditions can lead to a long-term huge chain reaction of the whole system. Interestingly, this ”butterfly effect“ has often been demonstrated in classroom teaching. ”Full course “ the biggest change to me, is that I understand ”the teacher must learn to put
