THIS BOOK CENTERS AROUND TWO MAIN THEMES: FIRST, RECONCILING INSTRUCTIONIST PEDAGOGIES BASED ON ASSIMILATION WITH CONSTRUCTIVIST TEACHING THAT EMPHASIZES ACTIVE LEARNING IS CENTRAL TO THE EVOLUTION OF EDUCATIONAL TECHNOLOGY. SECOND, INDUCING TELEPRESENCE THROUGH VARIOUS FORMS OF PHYSICAL AND PSYCHOSOCIAL IMMERSION IS AN EFFECTIVE MEANS OF INTEGRATING INSTRUCTIVIST AND CONSTRUCTIVIST APPROACHES. TOGETHER, THESE IDEAS OFFER A POWERFUL STRATEGY FOR IMPROVING EDUCATIONAL OUTCOMES THROUGH SOPHISTICATED INTERACTIVE MEDIA.
