If a kid really is retarded and can only come up to a certain level, he will still have more success if what he learns is connected with something important to him.

My basic idea is that programming is the most powerful medium of developing the sophisticated and rigorous thinking needed for mathematics, for grammar, for physics, for statistics, for all the "hard" subjects.... In short, I believe more than ever that programming should be a key part of the intellectual development of people growing up.

Do away with curriculum. Do away with segregation by age. And do away with the idea that there should be uniformity of all schools and of what people learn.

The first thing to note is that pornography and many abductions occur apart from the use of computers, and that most child abuse happens within the family. So I think the extra degree of danger that computers pose doesn't justify the frenzy.

My ex-student, Idit Harel, who wrote a book, "Children Designs," has a documented story of a kid who was very shy, isolated and didn't talk much to other kids. She was a little overweight, and the other kids looked down on her for that reason.But then she made a discovery about how to do something on the computer. The discovery was picked up by other kids, and within a few weeks there was a total transformation. This kid was now in demand. And that changed her feeling about herself.

Nothing could be more absurd than an experiment in which computers are placed in a classroom where nothing else is changed.

For what is important when we give children a theorem to use is not that they should memorize it. What matters most is that by growing up with a few very powerful theorems one comes to appreciate how certain ideas can be used as tools to think with over a lifetime. One learns to enjoy and to respect the power of powerful ideas. One learns that the most powerful idea of all is the idea of powerful ideas.
