TY - JOUR TI - Comparaison de compétences dans les approches algébrique, qualitative et informatique des équations différentielles ordinaires en première année universitaire. (Comparaison de compétence dans les E.D.O.) AU - Chau, Oanh AU - Pluvinage, François T2 - Recherches En Didactique Des Mathématiques AB - Today, teaching of ordinary differential equations can rely on three different approaches (algebraic, qualitative and use of mathematical software). By using data from a two years teaching experiment with undergraduates, we have compared the different abilities involved and studied their link to the other areas of mathematical analysis of the syllabus. The three approaches appeal to abilities that seem to be independent in the analysis of the tasks but, for instance, the students who were successful in the qualitative part of the final problem took better advantage of the graphic work in the problem solved with the software DERIVE, than those who dealt with the algebraic part with success. Indeed, it seems that eventhough facility in the qualitative method is more difficult to achieve, from a didactic point of view, it favours the transfer of knowledge.
