RESUMO

The objective of this study was to investigate the possibility of the appropriation of the concept of first degree functions to students of 3 rd grader of high school, from an intervention of education subsidized by technological tools. With this objective in mind, the study intends to answer the following question of research: What are the contributions to the education of relative concepts of first degree function that an intervention made with the use of the software graphmatica can bring? In order to do so, we carried out an almost-experimental study with students of two classes of 3 rd grader in a public high school in Cotia - SP, which had composed the groups of the study: the experimental group - GE - and the control group - GC. The research was carried out within three phases: Pre-testing, Intervention of Education and After-testing. The theoretical ideas that supported this study came from the Theory of Didactic Situations (BROUSSEAU, 1996), the Theory of the Conceptual Fields (VERGNAUD, 1998) and also the vision of the use of technologies in the light of the Etnomatematica (DAMBROSIO, 1998). GE participated in the three phases of the study, whereas the relative GC participated only in the phase of the diagnostic instruments (pre-tests and after-tests), but did not participate in the Intervention of Education. The data that were collected in this research were analyzed from a quantitative as well from a qualitative perspective (relative to the diagnostic instruments), as of the qualitative one (relative to the intervention of education). As it had been foreseen, the GE presented better results in the after-test than the GC. The data also indicated that the use of a graphical environment, which made dynamic essays, as well as the interaction provided by the use of graphmatica software, are fruitful contexts for learning. They facilitate the construction of new concepts and the comparisons with what had already been apprehended previously, therefore extending the Conceptual Field which consisted of the intersection between the reading and interpretation of graphs and expressions of the first degree function
