eJMT Abstract

The aim of the study is to investigate whether software can be useful in a process of forming the concept of parameter. The author also would like to show to what extent computer program can help in understanding different meanings of this concept during continuous contact with this tool in mathematics learning. Pupils at the age of 13–16 used different computer programs during a three-year period. They studied the parameter in different roles: placeholder, generalizer, changing quantity and unknown-to-be-found. The results indicate that the integration of mathematics and information technology could contribute pupils’ understanding of algebra concepts, particularly the concept of parameter.
