The research presented in this paper relies on Activity Theory and particularly on Engestrom's model, to better understand the use of Electronic-Exercise-Bases (EEB) by mathematics teachers. This theory provides a holistic approach to illustrate the complexity of the EEB integration. The results highlight reasons and ways of using EEB and show…

The aim of this paper is to emphasize some research results about teachers' practices in technology-based-lessons. Articulating several theoretical developments of Activity Theory enables us to conceive a frame to characterise the evolutions of these practices and to interpret them in terms of "geneses of technology uses". We consider these…

In this paper, our focus is on "young" mathematics teachers during their pre-service training because of the conditions that might enable them to develop professional uses of technology more easily than "older" teachers. By describing some aspects of teacher training in France, especially the distinction between level 1 (general) and level 2…
