2、pses. so you've - it's crap, isn't it really as we say.因为弄成这种视角 如果你脑中有了这种误解 用二度空间来呈现三度空间就会变成椭圆形 这真是糟糕，可不是吗so, these mental models - we look for evidence that reinforces our models. we do this, of course, with matters of race, and politics, and everything else, and we do it in science as
3、well. so we look, just look - and scientists do it, constantly - we look for evidence that reinforces our models, and some folks are just all too able and willing to provide the evidence that reinforces the models.因此，我们寻求证据来增强我们的心智模式 我们用这种方式处理种族、政治、所有事 当然也用这种方式处理科学，我们只观看 是科学家在这么做，我们不断寻求证据 来增强我们的心智模式
4、，有些人很有方法 也乐意提供证据来增强那些模式so, being i'm in the united states, i'll have a dig at the europeans. these are examples of what i would say is bad practice in science teaching centers.所以我现在人在美国，就会说欧洲人的坏话 这些图片都是我认为不良的科学教育these pictures are from la villette in france and the welcome wing of the scienc
5、e museum in london. and, if you look at the, kind of the way these things are constructed, there's a lot of mediation by glass, and it's very blue, and kind of professional - in that way that, you know, woody allen comes up from under the sheets in that scene in &annie hall,& and said, &god,
6、 that's so professional.& and that you don't - there's no passion in it, and it's not hands on, right, and, you know, pun intended.类似教学中心，这些图取自法国维叶特科博馆 以及伦敦科博馆的迎宾翼展示区 你看看这些东西建成的模样 有很多玻璃隔板，蓝光色调，弄得很专业似的 那种方式，就像是伍迪艾伦从床单里冒出来 在安妮霍尔戏中的那一幕 他说;老天，这真是太专业了; 这其中没有热情，没有动手参与，是吗 这是个双关，不过也有好的教学方法wh
7、ereas good interpretation - i'll use an example from nearby - is san francisco exploratorium, where all the things that - the demonstrations, and so on, are made out of everyday objects that children can understand, it's very hands-on, and they can engage with, and experiment with. and i kno
8、w that if the graduates at mit and in the imperial college in london had had the battery and the wire and the bit of stuff, and you know, been able to do it, they would have learned how it actually works, rather than thinking that they follow circuit diagrams and can't do it. so good interpretat
9、ion is more about things that are bodged and stuffed and of my world, right and things that - where there isn't an extra barrier of a piece of glass or machined titanium, and it all looks fantastic, ok我举一个例子，离这里很近，旧金山探索馆 在那里所有的东西，展示品之类的 都是用孩子能懂的日常用品做成的 都可以动手玩，孩子们可以专心玩好好体验 我知道麻省理工毕业生 以及伦敦帝国学院毕业生
10、手上有电池电线点亮灯泡的话 他们会明白其中的原理 而不是觉得他们照着电路图来做是做不到的 好的教学方法不是 沉溺陶醉在自己世界里对吧 那些东西也不该被隔着 用玻璃或是钛制品隔开 看起来很漂亮就好，好吗and the exploratorium does that really, really well. and it's amateur, but amateur in the best sense, in other words, the root of the word being of love and passion.旧金山探索馆在这点做得非常好 看上去很业余，但业余得很对头 也
11、就是说，根本的出发点是出自爱和热情so, children are not empty vessels, okso, as &monty python& would have it, this is a bit lord privy seal to say so, but this is - children are not empty vessels.所以，孩童不是空瓶子 用;巨蟒剧团;的说法 就是有点像英国掌玺大臣会说的 意思是说孩童不是空无一物的瓶子they come with their own ideas and their own theories, and unless you
12、work with those, then you won't be able to shift them, right他们生来就有自己的想法和理念 如果你没从这些地方着手，就改变不了他们 对吧and i probably haven't shifted your ideas of how the world and universe operates, either. but this applies, equally, to matters of trying to sell new technology.我大概没有改变大家的想法 对于世界和宇宙到底如何运作 不过这些道理同
13、样可以用在推销新科技上也for example, we are, in britain, we're trying to do a digital switchover of the whole population into digital technology for television.例如，在英国，我们试着把全部的电视 都换成新科技的数位电视and it's one of the difficult things is that when people have preconceptions of how it all works, it's quite di
14、fficult to shift those.有个难题是 人们对事物运作的方式一旦有了成见 就很难去改变so we're not empty vessels; the mental models that we have as children persist into adulthood. poor teaching actually does more harm than good.我们不是空瓶子，我们保有心智模式 从幼年到成年一直都存在 不良的教学是弊多于利in this country and in britain, magnetism is understood better
