Group Cognition: Computer Support for Building Collaborative Knowledge (Acting with Technology) ReviewThis book is, I may say, one of the kind of books I always wanted to have, to read and revisit for getting its golden nuggets. It is unique because it provides, from several different perspectives (technical as well as philosophical), deep insights in what is going on in computer-based collaborative applications, with emphasis on Computer-Supported Collaborative Learning. The need of collaborative applications is justified and analysed starting both from practice and theoretically. The text very well presents and analyses the valuable experience of the author in designing and implementing a wide range of applications in e-learning, groupware, artificial intelligence (expert systems and knowledge-based and text processing (Latent Semantic Indexing). This experience description may be better understood if we see the text almost as a saga ending with one of the main ideas of the book: knowledge building appears in verbal-mediated collaboration in small groups. The practical experiences are doubled by deep interdisciplinary theoretical considerations, including philosophy (integrating ideas from Heidegger, Vygotsky, Derrida, Bourdieu, Bakhtin, Adorno, etc.), learning sciences and sociology (e.g. Garfinkel's ethnomethodology, and Schegloff's and Sacks' conversation analysis). State of the art theories like activity theory, distributed cognition, situated learning, knowledge building, and group cognition are also integrated in the whole.Group Cognition: Computer Support for Building Collaborative Knowledge (Acting with Technology) OverviewInnovative uses of global and local networks of linked computers make newways of collaborative working, learning, and acting possible. In Group CognitionGerry Stahl explores the technological and social reconfigurations that are neededto achieve computer-supported collaborative knowledge building--group cognition thattranscends the limits of individual cognition. Computers can provide active mediafor social group cognition where ideas grow through the interactions within groupsof people; software functionality can manage group discourse that results in sharedunderstandings, new meanings, and collaborative learning. Stahl offers softwaredesign prototypes, analyzes empirical instances of collaboration, and elaborates atheory of collaboration that takes the group, rather than the individual, as theunit of analysis.Stahl's design studies concentrate on mechanisms to support groupformation, multiple interpretive perspectives, and the negotiation of groupknowledge in applications as varied as collaborative curriculum development byteachers, writing summaries by students, and designing space voyages by NASAengineers. His empirical analysis shows how, in small-group collaborations, thegroup constructs intersubjective knowledge that emerges from and appears in thediscourse itself. This discovery of group meaning becomes the springboard forStahl's outline of a social theory of collaborative knowing. Stahl also discussessuch related issues as the distinction between meaning making at the group level andinterpretation at the individual level, appropriate research methodology,philosophical directions for group cognition theory, and suggestions for furtherempirical work.

Patterns for Computer-Mediated Interaction (Wiley Software Patterns Series) ReviewWhenever I get a new book to review, I always approach it with a mixture of anticipation, curiosity, and dread, especially given the increasing number of books about patterns and, in this case, the size -- 581 pages! When I finally found a small window and sat down with "Patterns for Computer-Mediated Interaction," I was intending to hurriedly skim as much of the text as possible to get an idea of what it was like. Several hours later, I was hooked. What a surprise this book is! Yes, it's topical. The patterns are about developing software to allow people to have the best interaction experience possible. That is where the world is headed, no doubt! The patterns in this book, however, are not just about the technical aspects of these systems, the authors also address the "socio-technical" issues that are important for the people-side of this domain. What was especially interesting to me, as a long-time "patterns fan," was the intriguing and enlightening discussion of pattern languages and the close examination of the pattern language of Christopher Alexander. I've read many essays on this topic but this presentation was very special. I learned a lot. You can't ask for more than that. I can recommend this book whole-heartedly, not only for developers in this domain but also for anyone who wants to study a model pattern language and learn more about patterns and how they work together to solve problems. Two thumbs up!
Patterns for Computer-Mediated Interaction (Wiley Software Patterns Series) OverviewWritten by well-respected experts, this how-to guide provides patterns for the design of human computer human interaction (HCHI). An increasing number of applications are currently designed for use by more than one user, eg: multi-player games, interactive web sites, mobile phones, collaborative learning systems, interactive workspaces and smart environments. In these areas there is a shift from (HCI) human computer interaction to (HCHI) human computer human interaction. The role of patterns in this movement is twofold: 1st – patterns focus on the human user of the system; 2nd – patterns assist developers in the development process of groupware applications.
