Modeling competence in functional graph interpretation

Abstract

In this article we present a research where the Mathematics Competence Model (MCM) is applied to study the modeling competence, which is characterized by tasks, processes and modeling phases. The relationships between those three components determine the levels of cognitive complexity of a mathematical activity. The processes are the most outstanding components and they are developed during the whole school process, unlike the mathematical tasks, that are developed du¬ring shorter terms. The MCM is tested in a case study of a teacher who implemented a teaching unit for the interpretation of functional graphs.
