我正在寻找最酷的事情,你可以在几行简单的代码。我相信你可以用Haskell用15行写一个Mandelbrot集,但是很难理解。

我的目标是启发学生编程很酷。

我们知道编程很酷,因为你可以创造任何你想象到的东西——它是最终的创意出口。我想激励这些初学者,让他们尽可能多地克服早期学习的困难。

Now, my reasons are selfish. I'm teaching an Intro to Computing course to a group of 60 half-engineering, half business majors; all freshmen. They are the students who came from underprivileged High schools. From my past experience, the group is generally split as follows: a few rock-stars, some who try very hard and kind of get it, the few who try very hard and barely get it, and the few who don't care. I want to reach as many of these groups as effectively as I can. Here's an example of how I'd use a computer program to teach:

Here's an example of what I'm looking for: a 1-line VBS script to get your computer to talk to you: CreateObject("sapi.spvoice").Speak InputBox("Enter your text","Talk it") I could use this to demonstrate order of operations. I'd show the code, let them play with it, then explain that There's a lot going on in that line, but the computer can make sense of it, because it knows the rules. Then I'd show them something like this: 4(5*5) / 10 + 9(.25 + .75) And you can see that first I need to do is (5*5). Then I can multiply for 4. And now I've created the Object. Dividing by 10 is the same as calling Speak - I can't Speak before I have an object, and I can't divide before I have 100. Then on the other side I first create an InputBox with some instructions for how to display it. When I hit enter on the input box it evaluates or "returns" whatever I entered. (Hint: 'oooooo' makes a funny sound) So when I say Speak, the right side is what to Speak. And I get that from the InputBox. So when you do several things on a line, like: x = 14 + y; You need to be aware of the order of things. First we add 14 and y. Then we put the result (what it evaluates to, or returns) into x.

这就是我的目标,有一堆很酷的例子来演示,并在他们玩得开心的时候教他们。我在我室友身上尝试了这个例子,虽然我可能不会把它作为第一课,但她喜欢它,并学到了一些东西。

一些很酷的数学程序,可以做出漂亮的图形或容易理解的形状,这是很好的想法,我将研究这些。这里有一些复杂的actionscript示例,但这有点太高级了,我不能教flash。你还有什么其他的想法吗?

下面是一个用a - prolog语言编写的程序,它可以计算图的N种颜色(“c”表示颜色,“v”表示顶点,“e”表示边)。

c(1..n).                                           
1 {color(X,I) : c(I)} 1 :- v(X).             
:- color(X,I), color(Y,I), e(X,Y), c(I).

On a side note, the way I got my students excited last semester was to tell them a story. It went something along the lines of: "Picture a triangle. It's a purely mathematical object, no real triangles exists. We can reason about them, discover their properties, and then apply those properties towards real world solutions. An algorithm is also a purely mathematical object. Programming is a form of magic however. We can take a mathematical object, describe it a language, and lo and behold it can manipulate the physical world. Programming is a unique discipline that bridges these two worlds."

有趣的是,你提到了Mandelbrot集,因为用GW-BASIC创建分形是激发我在高中(大约1993年)对编程的热爱的原因。在我们开始学习分形之前,我们写了无聊的标准差应用程序,而我仍然计划进入新闻业。

但当我看到这个冗长、难以编写的BASIC程序生成“分形地形”时,我就被迷住了,再也没有回头。它改变了我对数学、科学、计算机的看法,也改变了我的学习方式。

我希望你能找到对你的学生有同样影响的项目。

在http://www.youtube.com/watch?v=a9xAKttWgP4上,你可以看到Conway的Game Of Life,它用大约5行APL(一种编程语言)编程(同时口头评论)。

它看起来很有趣,可以启发学生编程很酷,还有数学,数学,简洁的编程语言:)

顺便说一下,鲍勃·马丁叔叔在hanselminutes播客上提到了这个youtube视频。
