Developing and testing an online mock linear algebra exam with the STACK system.


The Boiler House

To what extent can we produce an automatically marked online version of a current paper-based examination for methods-based university mathematics courses using contemporary technology? To what extent are the outcomes of this exam equivalent to the outcomes of a paper-based exam?

This talk reports the development, use and evaluation of a mock online exam as part of an existing university linear algebra course using the STACK online assessment system.

The evaluation includes (1) professional judgement of the extent to which we believe the technology is suitable, and (2) statistical measures of the comparability of paper-based and online results. The results of this trial are cautiously optimistic: for a significant subset of existing examination questions online equivalents appear valid and practical.
