Learnable Programming

Here’s a trick question: How do we get people to understand programming?

Khan Academy recently launched an online environment for learning to program. It offers a set of tutorials based on the JavaScript and Processing languages, and features a “live coding” environment, where the program’s output updates as the programmer types.

Because my work was cited as an inspiration for the Khan system, I felt I should respond with two thoughts about learning:

• Programming is a way of thinking, not a rote skill. Learning about “for” loops is not learning to program, any more than learning about pencils is learning to draw.
• People understand what they can see. If a programmer cannot see what a program is doing, she can’t understand it.
