Three years of teaching resource sharing by primary school teachers trainees on a CSCW platform

In this paper, we propose a unit of analysis to study traces in CSCW, the higher level shared folder (hlsf), which we define. We use it here to analyze how teaching resource pooling and sharing has been operated by the teacher trainees within the IUFM de La Reunion for three years. We verify that this sharing was effective, we see how it was structured and we study its evolution during those three years.
