The design of educational technology has been driven mostly by technology and much too little by advances in instructional psychology and education. This book approaches educational technology from a psychological and educational point of view. Many of the chapters included draw the implications of cognitive theory for the construction of technology-based learning environments. Using specific examples, they show how technology could support the design of environments that are important to construct for educational and psychological reasons. Originating from a NATO Advanced Study Institute held in 1992, the book is part of the NATO Special Programme on Advanced Educational Technology.--This text refers to the Paperback edition.
