Article excerpt

INTRODUCTION

The progress in information and communication technologies and the birth of the internet has changed the end user computing experience and environment. This advancement has changed the way of delivering information and services. Information systems can now be web-enabled, unlike the traditional stationary information systems. Web portals are a part of this advancement. A Web portal is a gateway to information and services from multiple sources in a unified way, using a single, unique user interface (Tatnall, 2005). A Web portal usually features specific functions, such as search mechanisms, access to databases, user registration and personalization options. The use of web portals offered universities and postgraduate education huge opportunities for expansion, introduction of new services and development of both qualitative and quantitative ways of delivering information and services. More also, the need to satisfy the information requirements of postgraduate students in the University of Ibadan has brought about the large scale investment in the Postgraduate School web portal. There is therefore need on the part of the stakeholders to justify the huge investment in this area by measuring the impact of the information system on end-user satisfaction. The end-user satisfaction is regarded as the individual's attitude toward computer uses, or related activities required to perform tasks in an organization (Rainer and Harrison, 1993).

Aim of the Study

Sample and sampling techniques

This study used proportional stratified sampling technique to select a sample size of 385 postgraduate students. This represents 5% of the population (7,688). This number is considered sufficient due to time and cost factors. Proportional stratified sampling strategy is chosen for this study since each faculty represent a stratum and proportionality is applied so that the same percentage of elements from each stratum is drawn. Simple random sampling was used to select the respondents from each stratum. This probabilistic approach ensures that every element in the population has equal chance of being included in the study.
