How do we get people to understand programming? Khan Academy recently launched an online environment for learning to program.
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.
And live coding, as a standalone feature, misses the point. Alan Perlis wrote, "To understand a program, you must become both the machine and the program. A person is not a machine, and should not be forced to think like one. We turn it into something that's understandable by people.
Contents The concept of a system split between the computer and the head was derived from Will Wright's thoughts on games. A programming system has two parts.
The programming "environment" is the part that's installed on the computer. The programming "language" is the part that's installed in the programmer's head. This essay presents a set of design principles for an environment and language suitable for learning.
The environment should allow the learner to: The features are not the point We often think of a programming environment or language in terms of its features -- this one "has code folding", that one "has type inference".
This is like thinking about a book in terms of its words -- this book has a "fortuitous", that one has a "munificent". What matters is not individual words, but how the words together convey a message.
Likewise, a well-designed system is not simply a bag of features.
A good system is designed to encourage particular ways of thinking, with all features carefully and cohesively designed around that purpose.
Before a reader can make any sense of this code, before she can even begin to understand how it works, here are some questions she will have: What does "fill" mean? What do those numbers after "fill" mean? What do those numbers after "ellipse" mean? What units are these numbers in?
What ranges are they in? Why are there so many numbers? Khan Academy's tutorials encourage the learner to address these questions by randomly adjusting numbers and trying to figure out what they do. Imagine if you bought a new microwave, took it out of the box, and found a panel of unlabeled buttons.
Imagine if the microwave encouraged you to randomly hit buttons until you figured out what they did.Aug 25, · Expert Reviewed. How to Write a Persuasive Essay.
