Open Educational Resources: a Chance for enriching Mathematics Teachers’ Resource Systems?

International audienceThis contribution is dedicated to the changes brought about by the digitalization of information and communication in the design and uses of mathematics teaching resources: changes affecting the core resources of teachers; the curriculum materials and textbooks used by teachers (as evidences Pu’s contribution); teachers’ interaction with resources, as users (Rocha) as well as designers (Kynigos and Kolovou). One of the major changes, the focus of our contribution, appears to be the profusion of Open Educational Resources (OER), providing new opportunities for the design and usage of mathematics teaching resources. In order to analyse the effect of such opportunities we focus on two cases: the Sésamath association, providing OERs at a large scale in France; and a teacher using OERs as a means for accomplishing her teaching objectives. Through the lens of the documentational approach of didactics, we investigate such a provision of “resources-on-offer”, and its implications for teachers’ resource systems
