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?

您可以使用用AutoIt编写的脚本,它模糊了使用传统应用程序和编程之间的界限。

例如,一个脚本,打开记事本,让他们自己的电脑侮辱他们,并通过一个消息框,然后不留任何痕迹的行动:

Run("notepad.exe")
WinWaitActive("Untitled - Notepad")
Send("You smell of human.")
Sleep(10000)
MsgBox(0, "Humans smell bad", "Yuck!")
WinClose("Untitled - Notepad")
WinWaitActive("Notepad", "Do you want to save")
Send("!n")

在您提供的SAPI示例的基础上,我使用它来自己大声读取文件(只需将文本文件拖放到它的图标上或从命令行运行它)

speakfile.vbs:

strFileName = Wscript.Arguments(0)
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile(strFileName, 1)
strText = objFile.ReadAll
Set objVoice = CreateObject("SAPI.SpVoice")
objVoice.Speak strText

Choose any language (or framework) where drawing a dot, line, box or circle to the screen is trivial. Designing games is where a lot of programmers first find their passion, and graphical output is fundamental to this. Choose a language which lets them easily show off their work to friends. If they need to get their friends to install runtime frameworks and follow complicated instructions to show off, then they won't be getting the necessary kudos and comments they need. Don't underestimate the value of a peer saying "Hey, that's cool!"

也许考虑到这两个标准,Javascript和Processing.js或Flash可能是一个很好的起点,尽管Flash显然有要求..呃…闪光。

切题思想:Flash实际上是一种非常好的教授OOP的方法,因为当你真正看到对象和类时,更容易掌握它们的概念!

这段PHP代码只能通过命令行在Mac上运行,但当每个人都想玩Twister时,它非常有用

$lr = array('left', 'right');
$hf = array('hand', 'foot');
$colour = array('red', 'yellow', 'blue', 'green');
while(true) {
    $a = $lr[array_rand($lr)];
    $b = $hf[array_rand($hf)];
    $c = $colour[array_rand($colour)];
    system("say $a $b $c");
    sleep(5);
}

wxPython第一步

import wx
app = wx.App()
wx.Frame(None, -1, 'simple.py').Show()
app.MainLoop()
