May 30, 2019 from Coding Horror An Exercise Program for the Fat Web When I wrote about App-pocalypse Now in 2014, I implied the future still belonged to the web. And it does. But it’s also true that the web has changed a lot in the last 10 years, much less the last...

Apr 26, 2019 from Renfei Mao on flujoo 什么是智力测验？ 智力测验 人们用尺子量身高，用智力测验「量」智力。智力测验就是用来量你有多少智力的尺子。 智力不像身高，看不见摸不着，怎么量呢？ 思路和考试很像：心理学家会先设计一些题目让你做，这些题目会用到你的智力。你智力越高，题目做得就越好，得分就会越高。心理学家最后就根据你的分数来推断你的智力水平。 我们直接看具体的例子。 韦氏智力测验（Wechsler Intelligence Scale）是目前最...

Mar 25, 2019 from Renfei Mao on flujoo 什么是科学的课程设计？ 在教育行业，说一个东西是「科学的」往往是很高的评价。家长希望孩子上的培训课是科学的，培训机构也喜欢用科学来标榜自己。 那怎么样的课程是真正科学的？这篇文章从课程效果评估的角度来谈这个问题。 从课程效果说起 课程有没有效果，有什么效果，这些是家长非常关心的问题。 有的课程，效果评估起来比较简单，凭借直觉就可以判断。比如你上了减肥课，结果发现自己无情地胖了，那么你可以愤怒地说，这个课没效果！比如...
Mar 22, 2019 from Renfei Mao on flujoo 记忆训练有用吗？ 简单地说，有用。 但是记忆训练或者记忆策略并不只有单一的一种，本文将要探讨三类，这三类记忆训练侧重点并不相同： 第一类让你记得更「快」。 第二类让你记得更「多」。 第三类让你记得更「久」。 而这三类记忆训练的效果也各不相同： 第一类暂时缺乏有力的证据证明其有用。 第二类有用，但是效果的范围有限。 第三类有用，但是效果的程度有限。 第一类记忆训练：记得更快 简单粗暴地打个比方：记住东西的过程就...
Mar 14, 2019 from Renfei Mao on flujoo 要不要奖励孩子？ 奖励在教育中非常普遍。孩子考试得高分，父母买玩具作为奖励。父母这么做通常是希望通过奖励来进一步激励孩子的学习热情。 但你可能也听过这么一种观点，奖励不但没法激励学习热情，反而可能损害。奖励会让孩子觉得学习就是为了获得奖励。久而久之，孩子会失去对学习本身的喜爱。 哪种观点是对的？心理学对此有过深入的探讨，颇为曲折。我们来看一看。 核心概念：内部动机 批判奖励的观点认为，奖励会损害孩子的学习热情...
