Computer assessment of networks and communications module with large groups

The assessment and marking of large class sizes in many computing science courses is recognised as an increasing problem. Student expectation is such that marks and feedback to submitted assigned work should be available within a reasonable time period to deliver a quality of service which meets these expectations. At the University of Ulster, computer automated assessment was used to deliver such a service to students undertaking a module on Networks and Data Communication on a conversion type MSc course. Students were assessed overall using 3 methods: a series of on-line class tests, a multiple-choice question paper (taken under formal examination conditions but automatically marked), and a conventional examination paper. The results of each evaluation measure were analysed and conclusions drawn as to the validity of each assessment method, with the conventional examination paper considered as the benchmark.
