This work falls under historiographical perspectives that seek to include, in their productions, history, memory, and identity of groups that have been less valued, by assigning them a status equal to sources, perspectives and characters that have traditionally been treated as centrals. The constitution of oral sources provides to emerge opportunities identified by formed students, offering contributions to those who traditionally served as a source for researches in History of Mathematics Education. It is a contribution which adds additional interpretations to what has already been studied and enriches historical analysis about the process of modernization in mathematics teaching at Colégio de Aplicação da Universidade da Bahia. Two elements could be considered from the testimony of former students: considering that modernization was not a phenomenon accustomed only to mathematics, but to the various disciplines and practices of the Colégio and the identification of teacher Maria Augusta de Araújo Moreno as a highlighted reference of mathematics modernization at the Colégio.305612231243
