This study has two main objectives; first, to evaluate student perceptions on the technological aspects of the e-learning system, Second, to propose a model to determine the relationship between the technological factors and the perceived usefulness of e-learning. The main contribution of this paper is to propose and test six hypotheses that reinforce the relationship between technological aspects of e-learning and its perceived usefulness. A questionnaire survey of quantitative research methodology was applied and data was collected using an adapted survey instrument. The respondents were 306 Diploma of Engineering students. The findings revealed that four out of these six factors, namely the ease of access to portal, student-lecturer interaction, adequate technical support, and quality of Internet connectivity have a major influence on the perceived usefulness of e-learning. It is envisaged that the model can be very useful in increasing the usefulness and acceptance of e-learning in higher education institutions.
