Collective design of an e textbook: teachers' collective documentation
In this study, we investigated design processes in teacher collectives, which have been made possible by new "digital" opportunities: platforms, discussion lists, etc. The object of our study is the French Sesamath teacher association and its design of a grade 10 e textbook, more precisely the design of the "functions" chapter. We analysed it with two theoretical lenses: the documentational approach and cultural historical activity theory. We studied the activity system of a community of teachers designing an e textbook. At macro level, we observed a change of objects of the activities: from designing a "toolkit" for mathematics teachers; to interactive exercises; and finally to a more "classical e textbook" At micro level, we analysed the development of collective documents by the community, combining resources and schemes.
