CS Unplugged：不插电的计算机科学
CS Unplugged – Computer Science without a computer

导读
CS Unplugged 是一套无需电脑的计算机科学教学资源，用纸笔、游戏和活动讲解计算机科学基础概念，面向教师和学生。它强调计算机科学不等于写代码，核心是理解问题与计算思维。评论中还提到原书 PDF 链接以及把活动用于课堂的实际反馈。
为什么经久不衰：它把计算思维从机器和代码中剥离出来，提醒我们理解问题本身才是核心；活动对儿童和成人都有效，因此多年后仍是可用的教学经典。

CS 学位不等于编程；多数软件工作只是拼接工具或写业务逻辑，CS 背景更像护士的化学背景。
我记得本科阶段最早意识到的事情之一就是 CS != code。我觉得这本书在开头就把两者分开做得很好，如果我刚开始学的时候就有这样的教学，会很有用。后来我意识到，大多数要求 CS 学位的岗位其实并不让你做计算机科学。更多时候你是在把工具粘合起来，或者为某个具体应用写一堆无聊的业务逻辑；最糟的是维护一个旧单体，试图搞懂 15 年前某人的逻辑。在大多数软件工作中拥有 CS 背景，就像护士拥有化学背景一样有用。当然有些情况能帮你更快建立联系，但你绝不是化学家。

I remember one of the first realizations I made as an undergrad was that CS != code. I think this book does a good job of removing the two from the beginning, and it would have been useful for me to have instruction like this when I started learning. Later on I realized that most jobs that ask for a CS degree don't actually have you doing any computer science. More often you are glueing together tools or writing a bunch of boring business logic for some specific application at best. At worst you are maintaining an old monolith trying to figure out someones logic from 15 years ago. Having a CS background in most software jobs is useful in the same way having a chemistry background is useful to someone working as a nurse. Sure there will be situations where that knowledge might help you make a connection more quickly, but you're sure as hell not a chemist.
没有电脑反而迫使学习者深入理解问题；高水平开发者常花更多时间在纸笔和白板上思考。
几十年前，“没有电脑”是常态，因为电脑昂贵、非交互且难以使用。你必须在运行前写好整个程序，出错还要等很久才能重跑。如今电脑无处不在，几乎人人能立刻写代码，但我仍认为“老派”方式有很多好处。我共事过的许多高水平开发者最初学习时都没有持续接触电脑，所以这种教学非常有用——不让机器替你“做一部分思考”，会迫使你更深入理解问题，才能告诉机器该做什么。这些开发者也会花更多时间在白板或纸笔上，而不是写代码或调试。

Several decades ago, "without a computer" was the norm, because they were expensive, noninteractive, and/or difficult to access. You had to write your entire program before being given a chance to run it, and if there were any errors, you had to wait possibly a very long time before you could run it again. Now that computers are ubiquitous and nearly everyone can immediately start writing code, I still think there are many advantages of doing it the "old school" way. Many of the highly-skilled developers I've worked with started learning with no constant access to a computer, so I definitely think this form of teaching is very useful --- without a machine "doing some of the thinking" for you, as it were, it forces you to actually understand the problem more deeply, so that you can tell the machine what to do. Those developers are also the ones who will spend more time whiteboarding or writing with pencil and paper than they do writing or debugging code. Also, I thought this image depicted students being handed stacks of 5.25" floppies in their protective envelopes: https://storage.googleapis.com/cs-unplugged.appspot.com/static/img/general/how-do-i-teach-this.png
这些不插电活动对儿童和成人教师都很有吸引力，且能有效传达概念，适合 CS 基础课程。
我带着这些活动教过初中生、高中生和成年人（教师），它们总是非常吸引人，而且出乎意料地有效传达每节课要教的概念。如果你有机会构建 CS 基础课程，我 100% 推荐使用它们。

I've run these activities with kids (middle and high) and adults (teachers) and they have always been remarkably engaging and surprisingly effective at conveying the concepts each lesson is supposed to teach. I would 100% recommend using them if you ever get a chance to construct a CS fundamentals curriculum.
