This is a mirror site for the web site of Guy Broussseau, designed to make his site more accessible for Anglophones. It is being produced by Ginger Warfield ( as a perpetual work in process. I have translated this homepage, and some other key pages, and will continue to translate some entries, in particular Brousseau's summaries of his entries. Most links, however, will take the reader to the originals in French. For any reader who would like to know more about one of those originals, I am willing to provide some additional description and discussion (though only rarely a complete translation!)


In order to make it easier for the reader to connect this site and the original French language site, I have kept all of Brousseau's fonts and formats. In order to make it easier to spot the differences, I have converted the colors from blue to green strictly on the sections I have translated. Comments that I add myself will be in the color and font of this note.


  • This site is intended for the public, for teachers of mathematics at K-12 or secondary level, and for researchers in Didactique and in Education who are curious to know the origins and evolution of one of the first modern approaches to scientific didactique and mathematics education.

    It contains:

    Texts (publications, articles, observation notes,...) and thematic files accompanied by current commentary,
    A course given in 2010: the concepts and experiments of the Theory of Situations
    A blog: events, memories or responses to letters from visitors.

    Successive additions are presented as numbers of a journal, but all can be accessed directly.


  • THE journal OF THE site number 11

    The successive numbers of this journal present all of the documents newly made available to visitors to this site in the following categories:

    Editorial, Blog, Brousseau Archives, Files and Commentaries, the 2010 Course [an intensive two week course in which Brousseau summarized many concepts and developments of Didactique], updates to the pages on the COREM and the biographies of GB and Lucienne Félix. The publication times of the journal are expecte to be ... variable! The editorials, blog, ocmmentaries and courses will most often be new texts.

    All of the published articles on the site will have figured in some number of this journal and will, of course, remain accessible from the other tabs.



    The 2010 Course: Engineering of Curricula 3, First teaching of Statistics in Fifth Grade 2012

    Power Point 13: First teaching of Statistics in Fifth Grade

    Part 1 Narrative of the curriculum

    1. The first of the two power points, "Narrative", is a synthesized presentation of all steps of an experimental curriculum designed to introduce fifth fgrade students to Statics and to measures of events. The goal of experimentation with this curriculum was not immediately developing a teaching method, but responding to some important scientific questions.

    The "effects" of the "didactical contract" 1982

    Summary :
    The first part of the text presents sonme effects of the implicit but imperative "didactical contract": "Topaze", an example introductory to the notion of didactical contract, "Jourdain", "Papy", "Diénès", the abuse of analogy is denounced in a sketch by the humorist Raymond Devos. The text first presents various "failures" in the course of the modern mathematics movement:

    The COREM

    The Center of observation and research on the teaching of matheamatics and the Michelet School at Talence were for 25 years the most advanced laboratory of experimantal didactique of mathematics. How did it work? This site is the place where anyone who worked on this project in any capacity whatever: counsellor, teacher, researcher, etc., and principally the elementary school teachers of the Michelet School, can place their stories or their personal contributions. Perhaps it will make it possible to make known the incredible history of this project, unique of its kind, from its conception (1964-1973) and foundation (1973-75), its functioning, until the end of the contract (1975-1998), and the making available of its archives (2000 - 2010)

    Lucienne Félix

    The place for the works and publications of Lucienne Félix, indispensible links in the origins of didactique, is on this site, beside the works that they inspired. To them will be added all the documents and memories that contribute to honoring thememory of this pioneer, the mentor of the author of this site.
