Thinking Collaboratively is a theoretical and practical guide to thinking and learning in deep and meaningful ways within purposeful communities of inquiry. Critical thinking has long been recognized as an important educational goal but, until now, has largely been conceived and operationalized as an individual attitude and ability. Increasingly, however, a more relevant and complete cognitive construct has been emerging: thinking collaboratively. Thinking collaboratively is the means to inquire, test, and apply new understandings, and to make sense of the information that bombards us continuously. In short, thinking collaboratively is required to flourish in our highly connected world and, in this book based on more than a decade of research, Garrison provides an essential introduction to this vital concept.
