Hypermedia technology needs a creative approach from the outset in the design of software to facilitate human thinking and learning. This book opens a discussion of the potential of hypermedia and related approaches to provide open exploratory learning environments. The papers in the book are based on contributions to a NATO Advanced Research Workshop held in July1990 and are grouped into six sections: - Semantic networking as cognitive tools, - Expert systems as cognitive tools, - Hypertext as cognitive tools, - Collaborative communication tools, - Microworlds: context-dependent cognitive tools, - Implementing cognitive tools. The book will be valuable for those who design, implement and evaluate learning programs and who seek to escape from rigid tactics like programmed instruction and behavioristic approaches. The book presents principles for exploratory systems that go beyond existing metaphors of instruction and provokes the reader to think in a new way about the cognitive level of human-computer interaction.

They say there was or there wasn't in olden times a story as old as life, as young as this moment, a story that is yours and is mine. Once in a Promised Land is the story of Jassim and Salwa, who left the deserts of their native Jordan for those of Arizona, each chasing mirages of opportunity and freedom. Although the couple live far from Ground Zero, they cannot escape the dust cloud of paranoia settling over the nation. A hydrologist, Jassim believes passionately in his mission to make water accessible to all people, but his work is threatened by an FBI witch hunt for domestic terrorists. A Palestinian now twice displaced, Salwa embraces the American dream. She grapples to put down roots in an unwelcoming climate, becoming pregnant against her husband's wishes. When Jassim kills a teenage boy in a terrible accident and Salwa becomes hopelessly entangled with a shadowy young American, their tenuous lives in exile and their fragile marriage begin to unravel. Once in a Promised Land is a dramatic and achingly honest look at what it means to straddle cultures, to be viewed with suspicion, and to struggle to find safe haven.
