The Case Study of High School Students' Understanding of the
Concept of Parameter In A Computer Algebra Environment4)

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.
