The Two Versions of the CxG Formalism

This chapter continues with a discussion of the theoretical results on an “Internship-offer analysis” application modeled in the two versions CxG_1.0 and CxG_2.0 of the CxG formalism on an experiment with master's students. If all the students are concerned with the same objective, to realize the “Internship-offer analysis” activity, each student has the private goal of finding the “right” internship for themselves. The chapter gives the interpretation of the results based on different organizations of the contextual elements that lead to a collective task modeling in the CxG_1.0 formalism and as activity modeling for each actor of the group in the CxG_2.0 formalism (after the initial experiment). It then compares the results obtained in the modeling of the “Internship-offer analysis” activity with those obtained for the modeling of the “DVD-reader diagnosis” activity (also modeled by students).
