First, we study the status and role of proof in 11-16
years pupils'curricula and schoolbooks. We then develop our
thesis on possibilities offered by others mathematics fields
for the learning of proof. In order to support our thesis,
we investigate some specificities of proof practice in
Discrete Mathematics, especially from the viewpoint of truth
checking and validation.
I.
Elements of ecology of proof practice
II.
A new mathematics field for proof and news
problems
Conclusion
In this article, we have tried to analyse the status for
proof in French secondary School and to show the lack of the
question of Truth and Falsehood and the predominant position
of the activity of writting proof. We show also that, in the
usual mathematics activity in class, there are no links
between proof and modeling. Then, we present a few " basic "
situations for proof and modeling, in which meaning and
truth become central in the cognitive and teaching
process.
