2018-08-20勾股定理

原文：昨天莲妈妈发上了一个五秒钟的音频。我如获至宝。反复听“英语原音”是you know where s gray one.

这和我平时听的英语，稍有不同，但这才叫口语。

从我自学英语这495天里，就只听原音原声。坚决不听为了教学而给学生讲得书本英语。终于有了小成。就是再也不感到老外的语速快了。

昨天大家还谈到培养多语种人。莲妈妈是最有资格谈论其中的甘苦了。

回到教育孩子身上。我的观点:不要把孩子当作知识的容器，使劲往孩子的脑子里塞各种知识。我们不是让他们死记一大堆公式，多让他们接触大自然，多和孩子谈论为什么会这样。多和孩子谈论知识的来源。让他们学习前人的智慧。

不要全指望老师传授知识，不要全靠学校培养个创新型人才。说实在话，初高中的知识，都是老掉牙的常识。大学我没有读过，我不知道学的是什么。

也就是说，我们和孩子一起学习的，是前人早已证明了的事。

比如说勾股定理的证明方法。我们应该感谢邹元治，赵爽，梅文鼎，1876年美国总统Garfield,项明达，欧几里得，李锐，辛卜松，陈杰等等，给我们提供的不同思路方法。

再比如，谁第一次算出了月亮到地球的距离?他是怎样算出来的?开普勒怎么推算出行星归道公式的?我们家长做的就是复原当时的情景情况，陪孩子一起成长。

再给大家分享一个视频，算是我对以上观点的详解。；译文：Yesterday, mother lian sent out a five-second audio recording. I have been blessed. You know where s gray one.

It's a little different from the English I usually listen to, but that's spoken.

In the 495 days since I taught myself English, I have only heard the original sound. Never listen to books and English spoken to students for teaching purposes. Finally, a small success. I just don't feel like a foreigner talking fast anymore.

We talked yesterday about multilingual education. Lily is the most qualified to talk about the hardships.

Back to the education kids. My point: don't use your child as a container of knowledge. We don't want them to memorize a bunch of formulas, get them in touch with nature, and talk to kids about why that's the case. Talk to your child about the source of your knowledge. Let them learn from the wisdom of their predecessors.

Don't rely on teachers to impart knowledge. Don't rely on schools to cultivate creative talents. To be honest, junior and senior high school knowledge is just common sense. I didn't go to college. I don't know what it was.

That is to say, we learn with our children what has been proven before.

For example, the proof of the Pythagorean theorem. We should thank zou yuanzhi, zhao shuang, mei wending, 1876 US President Garfield, xiang mingda, Euclid, li rui, sinbu song, Chen jie and so on for providing us with different ways of thinking.

Or, for example, who first figured out the distance from the moon to the earth? How did he figure it out? How does Kepler figure out the planetary return formula? What we parents do is to recover the situation and grow with our children.

I'd like to share with you a video, which is my detailed explanation of the above views.。来自@有道.
