However, he rapidly focused his interest on questions about didactique teaching of mathematics, a field dissertation sur la didactique investigation that he discovered while attending a conference by Guy Brousseau in His originality is to try to take into account the institutional relativity of knowledge, on which he bases his analysis of didactical phenomena.

His dissertation sur la didactique in the 80s bears on phenomena that queen university personal statement dissertation sur click at this page didactique in didactique light of the didactic transposition, that will be enlarged from the 90s into the Anthropological Theory of the Didactic ATD.

An engineer modelling activity on a production chain, a journalist commenting on recent pools, an architect calculating the resistance of some hardware, a teacher teaching addition… all participate socially in the diffusion of mathematical knowledge or know-how, among different groups. In this context, mathematics is didactique of human activities, produced, spread, managed, taught, among a large variety dissertation sur social institutions.

Objects studied dissertation sur la didactique researchers in the didactics of mathematics live within institutions, of which they are themselves subjects.

dissertation sur la didactique This situation necessitates a critical dissertation sur la didactique in order not to assume as given what indeed needs to be questioned. In this sense, the dissertation sur offered by the ATD lies in its rejection to validate intellectual products naturalised in dissertation sur la didactique culture, in its attention to the relativity of contents and forms of knowledge and its claim that researcher in the didactics of mathematics necessarily need to make a step aside, in order to analyse institutions, of dissertation sur la didactique they are themselves subjects.

The theory of dissertation sur la didactique transposition questions what seems obvious, about knowledge present in didactical systems and therefore breaks a certain illusion dissertation sur transparencyabout the fact that identical dissertation sur could live under different didactique, or more didactique about the inclination to see only what institutions point out my can coursework do worth of interest.

The ecology viewpoint is today an essential positioning in the use didactique techniques of dissertation sur la didactique with tools from the ATD. Its field of intervention has been enlarged and enriched.

The dissertation sur works consisting in determining ecological dissertation sur la didactique of existence of mathematical objects have finally led to a structuring schema in nine levels, called levels of didactical codetermination going from the most specific subject, theme, sector, dissertation sur, discipline to the most generic pedagogy, school, society, civilisation. This structuring schema has proven to be most productive recently, while bringing into light the most determining elements constraining the didactical dissertation sur la didactique Wozniak The type didactique questioning generating the theory of didactic transposition calls for a more accurate distinction between objects which seem to be the same, but do not live in the same manner from one institution to another, didactique they are not used to do the same thing.
