Abstract
Starting from a general discussion on mathematical proof, a structural analysis was carried out, leading to the construction of a model within which indirect proofs can be described. The model shows itself a good interpreting tool to identify and explain cognitive and didactic issues, as well to precisely formulate research hypotheses concerning students' difficulties with indirect proofs.
