After having elaborated a proposal of characterisation of problems of finding well and ill defined and to observe the solvers behaviour in the " preparation " phase (Bourne and other, 1971), numerous researches questions arise, that led us to the necessity of elaborating an analysis outline, adapted of the pattern of Schoenfeld (1985), to observe to real solvers in this preparation phase, with problems of finding well and ill defined. In this work we are described, and we analyse the behaviours of some students of teacher training students specialising in Infant Education, when they face the solution of problems of finding ill defined in arithmetic, algebraic and geometric contexts in the " preparation " phase. In a concrete way, we analyse the type of proofs and arguments that use to justify their performances in validation or rebuttal terms.
