Formation of the mathematical modeling competence using digital technologies

In the OECD PISA documents, mathematical modeling competence together with the problem solving competence are listed as two of the eight basic mathematical competences. The mathematical modeling competence and the problem solving competence are closely related, because the use of different types of models that represent real objects and situations is the premise for development of the competence for solving real life problems. The transformation of existing problem into the mathematical language is the basis of mathematical modeling. In this article we describe the possibilities of using different types of models in solving of problems that enable the formation of the modeling competence. We use the MS Excel spreadsheet and dynamic geometric system Geogebra to model real situations.
