Enhancing Conceptual Insight: Plane Curves in a Computerised Learning Environment.

For questions in calculus, tables containing either intermediate or final results provide the student with a semi-graphical guide both to enhance their intuition and to help complete tasks. The joint usage of (hand-made) tabular presentations and of a CAS, in particular its graphical features, is particularly valuable in step-by-step working: such a learning process provides a more profound understanding of the mathematics involved and helps to develop better skills for solving problems. The examples considered include plane curves, either graphs of functions or parametric curves and space curves in implicit, parametric or polar form. [ABSTRACT FROM AUTHOR]
