RESUMO

This research has as objective verify if in a computer science environment allows to the student to recognize some curves properties through representations and graphical interpretations in dynamic way with the use of parameters for one comprehension better of its equations. We verified that the articulating between the points of view cartesian and parametric and the conversions among some registers of semiotic representation it makes the student think about the correlation that exists between some properties geometric of the plane curves and its cartesian or parametric equations. For this research we elaborate a didactic sequence based on some topics of the Didactic Engineering and we apply during five sessions in a group of 10 students taking the third year of high school. We verified that the graphic constructions of some plane curves varying the real values of its parameters in its equations for the development of an GIF (Graphic Information Format), they allow the students to observe the geometric effect caused by this variation what it favors the understanding of the parameter notion in analytical geometry
