The present master thesis aims to diagnostic the conception and competence of teachers concept of fraction. Theses teachers work in primary school and they are from Itabuna-Bahia. The study intends to answer the following question: What are the conceptions and competencies of primary school teachers about fraction and how do they think of the way to teach it? Having in mind both objective and research questions, we built a theoretical framework based on Vergnaud, Kieran and Nunes, Ponte s ideas. Afterwards, we elaborated an investigative instrument composed by 33 questions, divided into three parts and distributed in two volumes. The first part was concerned to draw the teachers profile (ten questions). The part 2 was concerned to identify teachers conceptions of fraction (18 questions). Finally, part 3 was to investigated teachers competence to solve problems (5) involving fraction, taking into account the five signifies presented by Nunes. The investigative instrument was applied in 52 teachers who come from 15 different shools. With regards to teachers profiles, the analysis showed that 86,6% out of them have between 6 and 25 career s years. All of them presented strong conception of fraction as both part-whole and multiplicative operator. As regarding to teachers competences, we found that the fraction as part-whole signify was the one which present best results, followed by measure and, thus, quotient. In general, teacher presented low performances in solving fraction s problems, which allow us to conclude that it is need to enlarge the mathematical knowledge of these teachers, as well as to realize in-service training which helps teachers to expand their conceptions of fraction and its teaching
