This book describes how two teachers, half a world apart, created collaborative Internet projects for high school students worldwide. Projects helped develop critical thinking, genuine dialogue, and global understanding in the classroom. Through the development of curricular projects linking classrooms in Malaysia, Japan, Iowa, South Africa, and England, teachers wrestled not only with technical problems of using the Internet, but also practical and philosophical questions related to serving their higher pedagogical purposes of nurturing genuine communication, dialogue, and argument. Nine chapters include: (1) "The Manabi Hut" (beginning the collaboration inside a hut in the Andes); (2) "The Web and the Plow" (the character of technology, what computers leave out, and what humans must bring); (3) "Don't Start the Evolution without Me" (descriptions of the projects); (4) "Utopian Visions, Dystopian Worries" (two early projects); (5) "Out of the Labyrinth, into the 'Net" (guiding adolescents in telecollaborative activities); (6) "The Global Suburb" (the assumption that projects enabling students to communicate with peers worldwide is beneficial); (7) "The Media Matter" (the genesis and evolution of one project); (8) "In Dreams Begin Responsibilities" (teacher responsibilities to students); and (9) "The Drama of Dialectics" (from which everything in the book springs).
