The purpose of the study was to investigate how students' understanding was formed for solving the algebra problems involving parameters in a computer algebra environment. The teaching experiment has been conducted with 6 high school students. As a result, students studied the parameter in different roles such as placeholder, changing quantity, unknown and generalizer. The results indicate that a computer algebra environment offers opportunities for algebra activities that may support the development of understanding of the concept of parameter.
