Lessons without limit: how free-choice learning is transforming science and technology education.

Societies are becoming nations of lifelong learners supported by a vast infrastructure of learning organizations. The centers of this learning revolution are not schools, but a network of organizations and media (museums, libraries, television, books, and increasingly the Internet) supporting the public's ever-growing demand for free-choice learning - learning guided by a person's needs and interests. Science learning is an important part of this revolution. Traditional boundaries and roles distinguishing groups of science educators and institutions are disappearing. To not understand and embrace these changes will impede our ability to enhance science learning worldwide.
