CABLE

Computer Algebra Based Learning and Evaluation

Overview

Computer algebra systems (CAS) are well-established research tools for performing symbolic manipulation of mathematical expressions, such as algebra and calculus. CABLE is designed to be a cost-effective, online infrastructure for writing, testing and databasing lightweight and flexible mathematical learning objects.

This infrastructure allows both staff and students to interact with computer algebra for the following functions:

• Instantiation and delivery of objects with randomised parameters.
• Evaluation and feedback of answers to questions contained in these objects. Typically each object has one question associated with it.
• Generation of worked solutions from templates with reference to the instantiated parameters.
• Simple analysis of answers from cohorts of students.

Design has preferred formative learning rather than assessment.
