  2. Introduction CABLE: Computer Algebra Based Learning and Evaluation A web-based, open source infrastructure for authoring, testing, storing, presenting and marking lightweight and flexible mathematical learning objects.

  3. System Features • Modular design approach to separate out CAS functions • Learning objects consisting of CAS instantiation instructions, question stem, marking procedure and solution template • Flexible options and answer tests that allow the same object to be used in different contexts • Relational database to store learning objects, students’ attempts against particular learning object instances

  4. Demonstration Implementation details: • PHP 4.3 • Logicampus VLE • Axiom CAS • www.cable.bham.ac.uk

  5. Future Work • Develop full working prototype • Investigate use of interoperability standards • Investigate assessment of individual steps (Beevers et al, 1995) to facilitate awarding of partial credit

  6. Acknowledgements This research is funded through: • The LTSN Maths, Stats and OR Network • Microsoft UK Limited
