This dissertation has as objective to understand the Pedagogic and Psycho- Pedagogic Orientations that made possible the construction of the educative experience of the Guatemala School, experimental institution tied with the Departmento de Aperfeiçoamento do Magistério (DAM) of the Centro Brasileiro de Pesquisas Educacionais (CBPE/INEP), with headquarters in Rio de Janeiro, when it was Federal District. For being a research in the field of the History of the Education, elaborated under the perspective of Cultural History, we appeal to interviews and to the documentary analysis of Lúcia Marques Pinheiro and Therezinha Lins e Silva personal files, Pedagogical Supervisor of the INEP and Coordinator of the Serviço de Orientação Psicopedagógico (SOPP), respectively. Starting of a permanent interlocution with Marcus Vinicius Cunha, it was possible to learn the types of orientations that the professors of this school had received during the years from 1955 to 1968, period understood as the end of the movement of the New School in Brazil. If by one side, the pedagogical orientation guided the practical teaching and, in this way, it limited the possibilities of manifestation of the subjectivity of these that taught, of the other side the psychopedagogic orientation provided the creation of a favorable and propitious climate next to the professors so that the pedagogical proposals could be placed in practical. In this way, in the first chapter, we search to characterize the educational and political context that marks the period; in the following one, we describe the way for which this school was organized by itself and developed its pedagogical action during the period; in the third chapter, we approach to the educational thought of Lúcia Marques Pine, for, finally, to evidence the Service of Psycho-Pedagogic Orientation, through its coordinator Therezinha.
