Ce qu'apporte l'exploration dynamique des données dans l'enseignement de la statistique.

The aim of this article is to show the easiness of exploratory graphs achievement with SAS/INSIGHT®, and the "cognitive" power of visual analysis. This visual analysis is part of learning strategy based on an exploratory approach of data. We demonstrate by variations around basic graphs, such as histograms, bar charts, scatter plots, rotating plots, contour plots, how an inexperienced user in statistics can better assimilate the object of statistics and get a better understanding of the limits of statistical treatments from his/her own mental representations. To explain the importance of mental representations in mathematics, we refer to the cognitive psychology and especially to neurosciences of learning. The methodology of the active pedagogy is based on the triptych : exploration, verbalization, formalization, in accordance to the headways of the new science of learning.
