That is an interesting entry into the xmca discussion group:
Kaptilinin, Engestrom, Bodker, Kuutti, and Nardi. It almost runs East
to West.
An important line of contact between that work focused on
adults and the work of many on this list focused more on children,
is an underlying agreement about the importance of studying human
nature over time, in motion, in the practices of everyday life. There
is also broad interest in issues of technological mediation and
collaboration.
At present, the topic of relations between the concepts of
activity, context, practice appears to be on the table. Your perspective,
like that of anyone who joins the discussion, has a lot to offer
in helping us make clear our ideas.
