“Function”, as it is understood today, formulates one of the most important concepts of mathematics. Nevertheless, many students do not sufficiently understand the abstract but comprehensive meaning of function and problems concerning its didactical metaphor are often confronted. The present study examines the interpretation of the concept of function among second year students of the Department of Education, at the University of Cyprus, and outlines their misunderstandings and possible obstacles in fully grasping its meaning. Results have shown that students’ perception of function appears in isolated components of mathematical ideas associated with the concept of function.
