Gerny, Marianne; Alpers, Burkhard – International Journal of Computers for Mathematical Learning, 2004
In this article we describe a mathematical microworld for investigating car motion on a racing course and its use with a group of grade 12 students. The microworld is concerned with the mathematical construction of courses and functions which describe car motion. It is implemented in the computer algebra system, Maple[R], which provides the means…
