Efectos del uso de la tecnología computacional sobre la articulación de los sistemas de representación de la parábola en un grupo de alumnos

Abstract

The present work is a result of a research based in the importance of the use of the computer technology in the different systems of the parable in a group of students. A pre-test was applied to an experimental group and a control group, of ten-degree students for this aspect, activity in the articulation of the representation systems were included. First the conversion from the algebraical system to the graphical system, which is the system to the students use in a best way, second, conversion from the graphical system to the algebraical where we found many difficulties. The experimental group was taught the articulation of systems representing the parable through the use of the educational software winlab. A post-test was applied to both groups later, which gave as a result that the experimental group which showed a great improvement in the conversion from the algebraical representation system to the graphical one. In the some way the result reflected that we have take, into account the conversion from the graphical system to the algebraical one in the teaching process of the parable, in order to get a better understanding of the subject, so the teacher must design activities where he use the articulation of the algebraical and graphical systems, which must be supported by the use of computer technology like a tool in the cognitive activity used in mathematics.
