This book contains adventures in digital geometry for the minds of students in pods and in home-schooling. Learning about geometry has inspired many of the most important thinkers for centuries and helped them to make sense of the world. This sequence of 50 hands-on challenges will step learners through the most exciting experiences of geometry, from basic points, lines and circles to construction and proof. The book is structured as a game: a series of thought-provoking challenges that provides a stimulating experience of collaboration with pod-mates and a fun introduction to geometry.

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.

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 established with conferences around the world and with this journal.
