Abstract
Refining mathematical understanding through the use of multiple representations and
negotiation of meaning has been considered important for students. This paper reports on
an observational study of students using a Computer Algebra System in an introductory
calculus unit at undergraduate level. There was strong evidence that the use of this technology
was a catalyst in students using these positive learning methods. However students felt that
the use of this technology aided but did not underpin their learning of mathematics.
