I think we should allow for schools within schools, where 100 out of 500 kids may be organized by the way they work and what they do, and what they do often is more progressive. I would like to see a lot of kids of different ages, maybe even some adults, work together on a project.

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.

I think schools generally do an effective and terribly damaging job of teaching children to be infantile, dependent, intellectually dishonest, passive and disrespectful to their own developmental capacities.

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.

The word constructionism is a mnemonic for two aspects of the theory of science education underlying this project. From constructivist theories of psychology we take a view of learning as a reconstruction rather than as a transmission of knowledge. Then we extend the idea of manipulative materials to the idea that learning is most effective when part of an activity the learner experiences as constructing a meaningful product.

Even with the most stupid video games, kids learn more about learning than they ever did before, because they want to learn codes and moves before other kids figure them out. They're motivated to seek out someone or search the Net for help. A student who makes a video game has to solve mathematical problems to make special effects happen on the screen.

You can't think seriously about thinking without thinking about thinking about something.
