You can't teach people everything they need to know. The best you can do is position them where they can find what they need to know when they need to know it.

We often treat children as if they're not very competent to do anything on their own. So we make them stop learning in a natural way - by exploring. Logo [the computer programming language ] allows them to find their way around the computer, as they would find their way around the house, uncontaminated by the bureaucracies of schools.

The scandal of education is that every time you teach something, you deprive a [student] of the pleasure and benefit of discovery.

Until very recently, most knowledge was inaccessible to people who couldn't read text. But this is changing. The computer opens up other channels of gaining knowledge. If someone is blind, we now have very good machines that will read to him. If someone can't recognize letters, he also will have access to knowledge through sound and images.

We should think about what we mean by literacy. If you say, "He's a very literate person," what you really mean is that he knows a lot, thinks a lot, has a certain frame of mind that comes through reading and knowing about various subjects.The major route open to literacy has been through reading and writing text. But we're seeing new media offer richer ways to explore knowledge and communicate, through sound and pictures.

I do think that we'd do better if we just offered all the bureaucrats in the Department of Education very attractive early retirements. But whether you want to abolish the department is another matter. Maybe there's room for recruiting a lot of visionary people who would do very good things: develop new techniques, new ideas, foster innovative models, disseminate those ideas.

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