Why Cats Happen to Fall from the Sky or on Good and Bad Models

Abstract

Teaching students to use mathematical modelling sensibly in realistic context is one general goal of mathematics education in order to educate students to become responsible citizens and future decision makers. Here, I want to discuss three important issues which can – depending on how teaching takes place – either promote or obstruct the development of students’ modelling competence. They are: Central examinations,Use of computers,Professional development and motivation of teachers. Remarks on these issues will be illustrated by examples.
