Cognition and Complexity uses the techniques of cognitive science to provide an innovative new way to cope with information. Thinking and knowing actually mean systematic comprehension (knowing the relationships and interdependencies between facts, processes and contexts) rather than accumulating data and facts. Reeves surveys the various models that organize complex information and synthesizes key aspects into a unified, hierarchical model. He leads readers step by step through a hypothetical situation so they can better understand how his model operates. Educators at all levels, particularly policy makers and practitioners in information science, will find that this experimental model supplies a solid foundation for new ways of learning and teaching in the coming century.
