According to its objective, this study employs the methodology called qualitative meta-analysis as Fiorentini and Lorenzato show, in order to find results that transcended those researches. The goals are achieves through the confrontation of those researches in their theoretical basis, with other theoretical frameworks proposed by Raymond Duval, Anna Sfard, Geraldo Ávila and Elon Lages de Lima.
