Software Quality and Usability for Computer-Based Test in Tertiary Institution in Nigeria: A Case Study of Kogi State University

Abstract

Software testing is essential for the development of technically sound software that performance especially during computer-based testing in e-examination. The purpose of this study is to investigate the software quality and usability for computer-based testing in Kogi State University. Information for the study was basically from the questionnaire survey and end-user participatory research method. Analysis of data was executed with the aid of Statistical Package for Social Sciences version 20, tables, percentages, ratios, graphs, group arithmetic mean (GAM) and mean weight values (MWV). The result shows that the basic details of students are covered in the software and it is easy to start. Regarding the user's interaction with the software and its features, a high number of respondents strongly agreed that the icons that are used to assist navigation are clear and intelligible. In a related issue, majority of respondents were of the view that the scoring system of the software is encouraging. Findings of this study also show that the grammar and vocab used in the software/program are accurate. It was deduced from the large response that the software includes pictures, that are relevant and aid in understanding. Respondents can easily give command to change answers, submit their answers, and exit the software during computer-based testing. Even at that, this paper argues for a more flexible data base, sufficient bandwidth, network structure flexibility, feedback mechanism and back-up systems, state of the art computers with high speed to further enhance usability of the software for computer-based testing in the institution.
