These are case studies of student teams using VMT to work on problems in the mathematical domain of combinatorics. The version of VMT used here included a generic whiteboard for sketching graphical representations. Data from these sessions was analyzed by a number of researchers in addition to the VMT project members.The essays in this volume were co-authored with close colleagues.

The volume includes essays that address the philosophical issues raised in computer support of collaborative learning and by the concept of group cognition. In particular, philosophy of group cognition should tackle the following questions: * What is the nature of group cognition? * What are the conditions of possibility for the existence of group cognition? The essays explore intersubjectivity, joint attention, common ground, collaborative learning and related concepts through analysis of empirical examples and review of the most important philosophic sources.

Essays in Group-Cognitive Science, intros to CSCL research, methodology and findings. Vol 10 of Gerry Stahl's assembled texts.

This doctoral dissertation in philosophy at Northwestern University considers the two most important philosophers of the modern age. I conducted my research during three years in Germany: at Heidelberg, where Heidegger's work was continued, and at Frankfurt, where critical theory extended Marx' thinking. In recent years, I have applied conceptual and methodological perspectives from Marx and Heidegger to the theory of CSCL. In particular, Marx countered the ideology of individualism by analyzing social structures and interpersonal interactions at different units of analysis than the...

As Editor-in-Chief of the International Journal of Computer-Supported Collaborative Learning from its founding in 2006 to my retirement from that position at the end of 2015, I drafted an editorial introduction to each quarterly issue. This provided a venue for me to comment on the importance of each published article (from my perspective) and sometimes to offer my ideas or reflections on the field of CSCL or one of its central issues. The 39 introductions included here provide a glimpse into the evolution of the CSCL field during a key decade of its history, as it became internationally...

This volume includes analyses of student teams using the VMT environment with multi-user GeoGebra. These studies are related to the presentations in -Translating Euclid- and -Constructing Dynamic Triangles Together.- These essays document the most recent stage of the Virtual Math Teams Project.

Translating Euclid reports on an effort to transform geometry for students from a stylus-and-clay-tablet corpus of historical theorems to a stimulating computer-supported collaborative-learning inquiry experience. The origin of geometry was a turning point in the pre-history of informatics, literacy, and rational thought. Yet, this triumph of human intellect became ossified through historic layers of systematization, beginning with Euclid's organization of the Elements of geometry. Often taught by memorization of procedures, theorems, and proofs, geometry in schooling rarely conveys its...
