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 by children before theyve been to school than afterwards, ok same for gravity, two concepts, so its which is quite humbling, as a, you know, if youre a teacher, and you look before and after, thats quite worrying. they do worse in tests afterwards, after the teaching.在美国和英国，在磁力知识上 孩童在就学前学得比较好 重力知识也一样，两个不同概念，这实在可悲 如果你是个老师，看见受教前和受教后的差别 实在令人忧心，学童在受教后考得更差and we collude. we design tests, or at least in britain, so that people pass them. right and governments do very well. they pat themselves on the back. ok我们都是共犯，我们设计测验方式 至少在英国是这样，好让人们能通过考试 政府也帮了不少忙，他们推波助澜 懂吗we collude, and actually if you if someone had designed a test for me when i was doing my biology exams, to really understand, to see whether id understood more than just kind of putting starch and iodine together and seeing it go blue, and really understood that plants took their mass out of the air, then i might have done better at science. so the most important thing is to get people to articulate their models.我们都是共犯 如果有人替我设计测验 在我要考生物的时候 让我能真正明白，明白我是否真的懂了 不是只在淀粉中加入碘液 看着反应呈现蓝色 而且能真正明白植物是从空气中茁壮的 我的科学可能就会学得比较好 所以，最重要的是要让人们能表述清楚他们的模型your homework is you know, how does an aircrafts wing create lift an obvious question, and youll have an answer now in your heads. and the second question to that then is, ensure youve explained how it is that planes can fly upside down. ah ha, right.回家作业是，机翼是怎样帮助飞机起飞的 这问题很好懂，大家心中也有答案了 注意事项是 你要确保自己能解释为何飞机头向下的时候也能飞， 对吧second question is, why is the sea blue all right and youve all got an idea in your head of the answer. so, why is it blue on cloudy days ah
