Sangwin, Christopher J.; Naismith, Laura – International Journal for Technology in Mathematics Education, 2008
We present principles for the design of an online system to support computer algebra enabled questions for use within the teaching and learning of mathematics in higher education. The introduction of a computer algebra system (CAS) into a computer aided assessment (CAA) system affords sophisticated response processing of student provided answers.…

Nicaud, Jean-Francois; Bouhineau, Denis; Chaachoua, Hamid – International Journal of Computers for Mathematical Learning, 2004
We present the design principles for a new kind of computer system that helps students learn algebra. The fundamental idea is to have a system based on the microworld paradigm that allows students to make their own calculations, as they do with paper and pencil, without being obliged to use commands, and to verify the correctness of these…
