Our qualitative research is part of a thought of Sciences of Education. It is based on interviews with members of the school system and specifically the actors who use ENT, Digital Work Environment. Our analysis is mainly based on the model of Wallet, PADI. Our systemic and multi referenced theoretical framework addresses the notion of innovation, the long process of integrating ICT in teaching practices, the impacts of ICT in teacher professionality. ICT modify access to educational literature. The distance learning systems leads to rethink the traditional act of teaching more in line with the act of learning throughout life. The uses of ICT by learners in schools are far from those anticipated, expected, required. Yet many financial and human investments are implemented every year a little more. We therefore wanted to try to understand the reasons for these differences. Then, we questioned the educational collective projects built around ENT applications modules, whose purpose was to serve the teaching, differentiated instruction, an educational support, guidance and openness to dialogue.
