This paper has as its focus the effect of a previous pedagogical experience on those taking a Math teacher's preparation undergraduate course. CEFAM (a Brazilian specific project that has as its main goal the preparation of future elementary teachers) is previous experience, and the Math teacher's preparation undergraduate course is one developed at UNESP (Bauru - SP - Brazil). The methodological approach is qualitative. Procedures of analysis were based on students' discourses, looking for convergences and divergences in their meanings.
