It shows how similar principles can help students understand what people experience when interacting with computers. The book also describes how the user's enjoyment of a computer system should be the biggest design consideration.

    The invaluable analytic skills developed through this innovative approach will appiv to anj, programming assignment-no matter the size of the problem or the language and macnine used. The book does not assume a high degree of familiarity with discrete mathematics-in fact, all mathematical concepts crucial to algorithm analysis are explained in the appendices. Each chapter centers on a basic problem and works through a variety of available . options for its solution rather than declaring a single best answer. Within the chapters, carefully orchestrated. 'Pauses'-helpful questions and strategy suggestions-point students to workable solutions and to increasinglv more advanced variations and applications. End-of-chapter 'Codas' restate each chapter's major themes and guide the transition into the next set of problems. Compared to What? will help students analyze problems, determine what needs to be optimized, and pinpoint inefficiencies and inaccuracies in their programs. Its fr-iendlv but challenging style, inventive examples 'and analogies, descriptions of state-of-the-art applications, and pragmatic focus will help you teach students to create algorithmic solutions-not merely memorize them.

    It argues that our thinking is shaped by others in a process known as socially shared cognition.
