Planning is an important human ability that guides behavior and thereby complements instinctual fixed action patterns. How do people learn to plan? How do they develop the various skills that are implied by planfulness? This new volume explores these questions as well as the concept of planing and its relationships to the concepts of problem-solving and organizational skills. The editors of this volume have drawn upon an international cadre of scholars to discuss the issues of planning and planful behaviours from a broad range of perspectives. The volume offers a comprehensive review and critical analysis of current research and theory on the development of planning ability. Cognitive and developmental psychologists, educational researchers, and students hitherto frustrated by the complexity of the thinking about planning and fragmentation of the literature will find Blueprints for Thinking an invaluable resource.
