  We would like to present results of an almost two years investigations about the role computer in the process of solving of mathematical problems. In these investigations took part 35 students of the secondary school (generalists) in the age 17–19 years. Each of these students solved following problem:
  Find all values of the parameter m so that the function
  f(x) = |mx + 1| − |2x − m| is:
  a) bounded,
  b) bounded only from the bottom,
  c) bounded only from above,
  first without a computer and next with a special computer program. We would like to show results of these researches.

  Pupils are encountering difficulties with learning algebra. In order for them to understand algebraic concepts, particularly the concept of parameter it was decided by the teacher of mathematics and Information Technology to integrate the teaching of these two subjects. The aim of this study is to investigate whether, and to what degree, software can be useful in process of forming the concept of parameter. This longitudinal study was conducted in a junior high school (13-16 year old children) using different computer programs.
