Context Reﬂexivity and traces Modelled traces Our trace models Prototypes in progress Conclusion and perspectives Context Online synchronous collaborative learning is characterized by size: small closed group activity’s structure: teachers specify the content collaboration: strong human exchanges time: synchronicity Damien CLAUZEL, Karim SEHABA, Yannick PRIÉ Model. and visu. traces for reﬂex. in sync. coll. act. 3 / 25

Context Reflexivity and traces Modelled traces Our trace models Prototypes in progress Conclusion and perspectives Context Our goals are to support group activity to support individual reflexivity to support group reflexivity to describe human activity on computer to create a memory of past interactions Damien CLAUZEL, Karim SEHABA, Yannick PRIÉ Model. and visu. traces for reflex. in sync. coll. act. 4 / 25

Context Reflexivity and traces Modelled traces Our trace models Prototypes in progress Conclusion and perspectives Metacognition for learning Metacognition is important in learning, and needs reflexivity [Worrall and Bell, 2007] Metacognition [Flavell, 1976] [is] one’s knowledge concerning one’s own cognitive processes or anything related to them. . . For example, I am engaging in metacognition if I notice that I am having more trouble learning A than B; if it strikes me that I should double check C before accepting it as fact.

Context Reflexivity and traces Modelled traces Our trace models Prototypes in progress Conclusion and perspectives Why reflexivity? Reflexivity of activity allows: metacognition awareness group synchronisation We identify three levels of reflexivity: individual, extended and group. Let’s have a look at them!

Context Reflexivity and traces Modelled traces Our trace models Prototypes in progress Conclusion and perspectives Different levels of reflexivity Conclusion : a need to filter and to share reflexivity within a group: on an individual base on a collective base Our approach : we use modelled traces for working with reflexivity Damien CLAUZEL, Karim SEHABA, Yannick PRIÉ Model. and visu. traces for reflex. in sync. coll. act. 11 / 25

Context Reﬂexivity and traces Modelled traces Our trace models Prototypes in progress Conclusion and perspectives What is a modelled trace? Modelled trace We call “modelled trace” a collection of observations, temporally situated, associated to an observation model. ⇒ for short : a modelled trace is a formal representation of user’s interactions A modelled trace can be processed, transformed, shared and visualised.
