%0 Journal Article %T Folders shared by the trainees with or without trainer at the teachers ' school of La R¨¦union : Trace analysis %A Jean Simon %A Jean-Paul G¨¦rard %A Claudine Th¨¦venin %J STICEF %D 2008 %I %X Since September 2005, the Teachers College of La R¨¦union uses a CSCW platform (BSCW). In this paper we analyze the behaviour and actions of the primary trainee on this platform according to the type of group they belong to: groups made up of only peers or groups made up of peers and trainers. The second type (including trainers) should be more restricted than the first. We wish to compare the peers¡¯ role and participation in each of these types of groups: free or restricted. This analysis is based on the traces left on the platform. In this paper, we also offer a definition of the "higher level shared folder" which is used as the unit of analysis. Such an entity reflects the activity of a group working jointly to solve a problem. In the discussion, we reconsider the limits of the method employed and the results obtained %K Methodology in trace analysis %K CSCW %K Teachers training %K Activity Theory %U http://sticef.univ-lemans.fr/num/vol2008/02-simon/sticef_2008_simon_02p.html
