The purpose of this book is to highlight the continuing research of military and academic communities - research aimed at developing new approaches in the instruction of complex intellectual processes and skills. Representative work includes learning procedural tasks and learning text comprehension processes in various environments such as computer-managed instructional settings. A variety of technological factors relevant to developing training materials for computerized environments is also presented, with new topics such as learning map interpretation skills. This collaborative effort was supported by the Navy Personnel Research and Development Center in San Diego, California. The essays have been contributed by military personnel research organizations and universities, and the book should be of value to educators in the academic and military worlds.
