The full text of Perkins' “Teaching for Understanding,” which first appeared in the Fall 1993 issue of American Educator and describes the author's work and thinking, is available online within the website of the 21st Century Learning Initiative. The initiative is a “transnational programme to synthesize the best of research and development into the nature of human learning, and to examine its implications for education, work and the development of communities worldwide.” Its site contains the full texts of a number of articles relevant to the initiative's goals and to teaching for understanding, including work by Alan Collins, Howard Gardner, and Neil Postman.
