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.

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.

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

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.

I tell adults about the experiences of more than a hundred teachers I've interviewed. They tell me that allowing the child to help them learn helped them become better teachers. That's because they no longer had to pretend they were the experts - not only about computers but about other things.

A programming language is like a natural, human language in that it favors certain methaphors, images, and ways of thinking.
