May Adults lie constantly to kids. I'm not saying we should stop, but I think we should at least examine which lies we tell and why.
How do we get people to understand programming? Khan Academy recently launched an online environment for learning to program. 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.
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. A programming system has two parts. 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.

This essay will present many features! The trick is to see through them -- to see the underlying design principles that they represent, and understand how these principles enable the programmer to think.
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?
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.
Now, imagine if your cookbook advised you that randomly hitting unlabeled buttons was how you learn cooking. Make meaning transparent Learning cooking is not about guessing the functionality of your kitchen appliances.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. Essays come in many forms. In this lesson, you'll learn all about a narrative essay, from its basic definition to the key characteristics that make.
