Uma ilha interdisciplinar de racionalidade para construção do conceito de função matemática

Abstract

This work describes the planning, elaboration, application and analysis of an Interdisciplinary Island of Rationality (IIR), aiming at the analysis of its potencial in the construction of the mathematical function’s concept. According to Fourez (1997), IIR is a teaching method focused to Scientific and Technological Literacy, aimed at the training of autonomous and with capacity for communication students in demand. The research problem created the questioning: What is the collaboration of IIR elaborated for the construction of the mathematical function’s concept? To answer it, was planned and applied a IIR in a class of 1st year in High School, in the last quarter of the 2016, in a state school in Gramado, Rio Grande do Sul, Brazil. The research is qualitative, applied, descriptive and participant. The learning results were collected through the observation and analysis of students’ productions. Some evidence has revealed results according to students’ predisposition to learn and understanding the mathematical function’s concept in real situations. As for Scientific and Technological Literacy goals, the students demonstrated mastery of the analyzed situations, autonomy in the production and knowledge investigation and communication hability, in the sense given by Fourez.
