Dissertação (Mestrado em Ensino de Ciências Naturais e Matemática) - Universidade Federal do Rio Grande do Norte, Natal, 2007.https://repositorio.ufrn.br/jspui/handle/123456789/16119This study describes about graduation s students difficulties of to draw functions graph. Specifically, we intend to observe their abilities evolution, as well as their difficulties during Calculus I subject in engineering course. For that, we show them publications about the elaboration of graphs and its difficulties in obstacle terms and some researches witch contain this subject and that it was done during postgraduate studies in mathematical education. It shows by research methodology aspects related to French didatic s mathematic and some theories of cognitive psychology considering the high value between theoretical-methodological relation that was evidenced in both theoretical conceptions about ways to understand and teach mathematic. This methodology is based on didactic engineering purpose, that consist in preliminaries analysis, conception and didactic sequence analysis prior, trials by application followed analysis up and conclusion. We had also used pedagogicals actions and analysis of results achieved, to classify types of errors made by the 2005 s students during second semester, from conceptions related to the episthemologic and didactics obstaclesapplication/pdfAcesso AbertoGráfico de funçõesengenharia didáticadidática da matemáticaFunctions graphDidactic engineeringDidactic s mathematicsmasterThesisCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICA
