Book excerpt: Online education or instruction--any form of learning/teaching via a computer network, i.e. Internet, WWW, or LAN-is rapidly becoming a major mode of educational delivery used by schools, colleges, and corporations. ONLINE EDUCATION is a comprehensive introduction to and overview of learning and teaching in "cyberspace." Kearsley, an author of Wadsworth's DISTANCE EDUCATION: A SYSTEMS VIEW, provides pre-service and in-service teachers, college faculty, and staff with a formal survey of this new and growing educational paradigm.
