Buch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - The key idea of the book is that scientific and practical advances can be obtained if researchers working in traditions that have been assumed to be mutually incompatible make a real effort to engage in dialogue with each other, comparing and contrasting…their understandings of a given phenomenon and how these different understandings can either complement or mutually elaborate on each other. This key idea applies to many fields, particularly in the social and behavioral sciences, as well as education and computer science. The book shows how we have achieved this by presenting our study of collaborative learning during the course of a four-year project. Through a series of five workshops involving dozens of researchers, the 37 editors and authors involved in this project studied and reported on collaborative learning, technology enhanced learning, and cooperative work. The authors share an interest in understanding group interactions, but approach this topic from a variety of traditional disciplinary homes and theoretical and methodological traditions. This allows the book to be of use to researchers in many different fields and with many different goals and agendas.

Illustrated throughout with drawings, photographs, programs, comic book covers and drawings, movie posters and promotional materials, memorabilia, behind the scenes photos, and more. Comic-Con began in 1970 in San Diego and continues as a very special place for artists, fans, writers, celebrities, and other professionals to gather in celebration of all things wonderful in the world of comics, science fiction and fantasy, film, videos, anime, and fun. From Ray BradburyÕs foreword: ÒWhen I was in my late forties, I was asked to come down to San Diego to attend the first Comic-Con at the El Cortez Hotel. I was part of a group of about three hundred people, if you can believe that. The fascinating thing about this was that these people all loved illustration. We were all very happy being there and enjoying one anotherÕs company.Ó Accompanying Bradbury (who is featured extensively throughout the book) at that first gathering were such luminaries as A.E. van Vogt, Jack Kirby, and Forrest J Ackerman.
