f*******3 发帖数: 1371 | 38 俺也说说。 看这个意思,就是好的教育是培养一个problem solver, 而不是一个百科
辞典。学的时候要带着问题学,以解决问题为目标而不是以记住知识为目标来学。
父母对孩子当然还要有指导,但怎样的指导才能既不压抑孩子的探索又有适当的鼓励和
引导呢,就看孩子的个性和场景了。这方面,只有我想只有通用的理论,没有万能的做
法。只要你注意到了这个问题,理解应该let the children do the thinking,应该不
会有太多问题。比如不能说“good job", 为啥?俺娃能干还不能表扬了啊? 这话也不
见得一定不能说啊,所以与其看他的条条框框,不如先理解他这么建议的原因,再针对
自己孩子的个性找出适合他的方法。
俺是相信孩子都天生有求知欲,有明确表达自己思想和看法的愿望的,那些看起来不够
好奇,或者显得没有opinion的孩子,除了可能因为受了压抑或者自身表达水平不高之
外,多半是父母没有能够抓住孩子的“兴趣点”,没看出来他好奇,他也没有问,就这
样过去了。所以我才觉得跟孩子spend time together doing nothing很重要, 只有在

0.111111111 ....
凑个 9,竖式除法算 1/9,从 iterative solver 的角度看:
we know final x = 1/9
s1: 0.1 < x < 0.2
s2: 0.11 < x < 0.12
s3: 0.111 < x < 0.112
s4: 0.1111 < x < 0.1112

上面这么看起来不清楚的话,干脆完全给整数化,

s1: 9/90 < x < 18/90
s2: 99/900 < x < 108/90
s3: 999/9000 < x < 1008/9000
s4: 9999/90000 < x < 10008/90000
