ab: Summary: This paper concerns computer aided assessment (CAA) of mathematics
in which a computer algebra system (CAS) is used to help assess
studentsâ€™ responses to elementary algebra questions. Using a
methodology of documentary analysis, we examine what is taught in
elementary algebra. The STACK CAA system, {\tt
http://www.stack.bham.ac.uk/}, which uses the CAS Maxima, is taken as a
case study with which to test the implementation of the ideas developed
in this paper. The general characteristics needed from a CAS for the
application of computer aided assessment, or computer based learning is
discussed. In particular the need for consistently implemented noun
forms of elementary arithmetic operations, together with their
traditional verb forms is identified.
