This allows information to circulate constantly between them. Also a journal, Reperes-IREM, is being published. The CII gather members of various IREMs interested in the same theme or problematique. They synthesise studies done by the local groups. Conversely, they send questions to the local groups which extend or expand on the initial themes.
Some commissions have their own projects.
They ensure the dissemination of their work through publications as well as through meetings and summer schools. The activity of the IREMs has evolved significantly since their creation. The IREMs turned out to be the places where the serious difficulties to which the reform initiated in 1967 led, were detected and analysed. In that context IREM members from all teaching levels realized that a deep and scientific study of the learning process and the relationship between teaching and learning was urgently needed. In this way the IREMs contributed to the further development of the mathematics curricula in France.
