conference contribution
posted on 2009-05-14, 12:59 authored by Trevor BarkerThis paper presents a summary of a six year study into the design,
implementation and evaluation of a computer-adaptive test (CAT) for the
assessment of Computer Science undergraduates in a UK university. In the
first part of this project, a series of empirical studies were carried out in order
to evaluate the contribution that the CAT approach could make to the
assessment of Computer Science undergraduates. A brief summary of this
research is presented in this paper. It was found in this research that the
developed CAT was effective at tailoring the level of difficulty of the test to the
ability of individual students. The two main groups of stakeholders, students
and academic staff, both exhibited a positive attitude towards the CAT
approach and the user interface. In the main part of this paper, the validity
and reliability of the CAT approach is assessed. Two empirical studies were
undertaken in order test the CAT’s validity and reliability and the results of
these studies are presented here. Findings from this research are interpreted
to show that in the context of assessment in Higher Education, the CAT
developed in this research was valid and reliable. In the concluding section
these findings are discussed in relation to other research in this area.
