These essays are some of the most important papers co-written with my
colleagues that supplement the discussion of CSCL research in the
published books. These chapters take the discussion in specific
directions. They begin with my general reflections on the importance of
CSCL as a research field, situating my work on the VMT Project and my
theory of group cognition within the field of CSCL. They describe the
VMT research project, including its research approach, technology,
pedagogy and analysis methods. Mostly, they discuss in some detail the
findings that have emerged from the VMT Project about the nature of
online interaction in that type of CSCL setting. The volume concludes
with reports of work in the project and future directions that were
underway.
