我建议从C/ c++开始。我发现它是几乎所有其他语言的良好基础。此外，不同版本的BASIC语言最多也会很不可靠，而且与实际的编程没有真正的关联。

有一本维基百科非常适合学习python。

我不知道其他语言的维基百科是怎样的，但我个人是从2007年2月的维基百科上学习python的

Ps -如果你不熟悉维基书，它基本上是维基百科版本的书籍创作。这有点难以描述，但如果你看了几本书你就会明白它是如何工作的

一行一行地复制一些简单的代码，让他们一边读一边理解。他们很快就会解决的。我开始用Acorn杂志上的代码片段在Acorn Electron上编程。在我6岁的时候，我对编程一无所知，我习惯抄写文本，但渐渐地我学会了不同单词的意思。

我通过学习如何使用流程图和PDL(程序设计语言)以语言无关的方式解决问题。几周之后，我学会了把我写的PDL转换成一种语言。我很高兴我学会了这种方法，因为我大部分时间都在编程，解决问题，而不依赖于语言。我使用什么语言一直是实现细节，而不是设计的一部分。

通过将问题分解为基本步骤来解决问题是一项关键技能。我认为这是区分那些会编程和不会编程的人的一个因素。

至于如何处理语言概念的顺序，我认为最简单的方法是在脑海中有一个项目，并根据需要处理这些概念。这让你可以在你感兴趣的事情上应用它们。在学习一门语言的时候，最好在脑海中有几个简单的计划，还有几个逐步复杂的计划。决定这些将帮助你规划出需要的概念和它们的顺序。

我推荐Logo(又名乌龟)来了解基本概念。它提供了一个具有即时图形反馈的良好沙盒，您可以演示循环、变量、函数、条件等等。这个页面提供了一个很好的教程。

在Logo之后，移动到Python或Ruby。我推荐Python，因为它基于ABC，而ABC是为了教授编程而发明的。

在教授编程时，我必须赞同EHaskins关于先简单项目再复杂项目的建议。最好的学习方法是从一个明确的结果和一个可衡量的里程碑开始。它使课程集中，允许学生建立技能，然后在这些技能的基础上继续发展，并给学生一些可以向朋友炫耀的东西。不要低估工作成果的力量。

Theoretically, you can stick with Python, as Python can do almost anything. It's a good vehicle to teach object-oriented programming and (most) algorithms. You can run Python in interactive mode like a command line to get a feel for how it works, or run whole scripts at once. You can run your scripts interpreted on the fly, or compile them into binaries. There are thousands of modules to extend the functionality. You can make a graphical calculator like the one bundled with Windows, or you can make an IRC client, or anything else.

XKCD更好地描述了Python的强大功能:

You can move to C# or Java after that, though they don't offer much that Python doesn't already have. The benefit of these is that they use C-style syntax, which many (dare I say most?) languages use. You don't need to worry about memory management yet, but you can get used to having a bit more freedom and less handholding from the language interpreter. Python enforces whitespace and indenting, which is nice most of the time but not always. C# and Java let you manage your own whitespace while remaining strongly-typed.

From there, the standard is C or C++. The freedom in these languages is almost existential. You are now in charge of your own memory management. There is no garbage collection to help you. This is where you teach the really advanced algorithms (like mergesort and quicksort). This is where you learn why "segmentation fault" is a curse word. This is where you download the source code of the Linux kernel and gaze into the Abyss. Start by writing a circular buffer and a stack for string manipulation. Then work your way up.

Something you should be very mindful of while teaching your brother to program is for him not to rely too heavily on you. Often when I find myself helping others they will begin to think of me as answer book to all of their questions and instead of experimenting to find an answer they simply ask me. Often the best teacher is experimentation and every time your brother has a question like "What will happen if I add 2 to a string?" you should tell him to try it out and see for himself. Also I have noticed that when I cannot get a concept through to someone, it helps to see some sample code where we can look at each segment individually and explain it piece by piece. As a side note people new to programming often have trouble with the idea of object oriented programming, they will say they understand it when you teach it to them but will not get a clear concept of it until actually implementing it.
