ab: Summary: 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. Randomised question parameters and immediate, tailored
feedback support a pedagogy of practice. We introduce a mathematical
question type that encapsulates these features and describe its
implementation within the CABLE online system. In CABLE, the question
authoring process is supported through options and by providing a
programming-free interface for teachers.
