Ten experts in the field of programed instruction have contributed articles to this book. The articles are designed to show what programed learning is, where it is currently being used and with what success, and how to make the most effective use of programed materials. They demonstrate the use of programed instruction in spelling, reading, social sciences, foreign languages, and mathematics, as well as in the nongraded school, job corps, adult education, and colleges and universities. Some of the articles are presented in programed form; others use programed material extensively to make their point. A list of notes and references and a subject index supplements the text.
