to uniserveedit06@usyd.edu.au I think that I would prefer a paper to a poster, but any method whereby I can demo at least some of the systems is OK. If I give a paper, I would need internet access for a laptop with display through the overhead projection system. With a poster, just internet access would be OK. The title and abstract follow.

The Computer Aided Assessment (CAA) systems treated in this paper * involve the delivery of questions across the web; * are underpinned by Computer Algebra (CA) packages. The CA underpinnings allow the students to to enter answers, have them parsed by the CA system, type-checked by the CA system, and then passed through a marking procedure which can recognize any correct form of the answer. The CA underpinning also allows one to generate model solutions (after due-dates) and to provide many forms of feedback. In this way, the systems are more for "Computer Aided Learning" than for "Assessment". These CAA systems have been successfully used in a moderate number of Mathematics Departments, but few Physics Departments. One function of the paper is to publicise them to a wider community. In particular, the underlying CA packages are widely used by physicists (and, in some cases, were written by physicists). As authoring for any of these CAA involves coding in the CA package underpinning it, physicist users of the same CA are well-placed to use the CAA systems. Information, and often guest logins, to some of the systems are available at http://aim.maths.uwa.edu.au https://calmaeth.maths.uwa.edu.au http://stack.bham.ac.uk http://weblearn.rmit.edu.au The CAA systems range from * totally free and open-source (e.g. stack, underpinned by maxima), through * free and open-source except for the CA (e.g. AiM, underpinned by maple), to * commercial (e.g. mapleTA and webLearn- both underpinned by maple- and calmaeth and MyMathLab/mathxl -both underpinned by mathematica). The integration of this sort of CAA with widely used Managed Learning Environments (WebCT, moodle, etc.) is developing. This would harmonize the students' learning experience across different subjects (at the very least avoiding a separate login for the mathematics CAA). We will speculate on how the genre may develop.
