Why some teachers easily learn to use a new virtual learning environment: a technology acceptance perspective

After a decade of virtual learning environments (VLEs) in higher education, many teachers still use only a minimum of its affordances. This study looked at how academic staff interacted with a new and unknown VLE in order to understand how technology acceptance and support materials influence (perceived and actual) task performance. In an experimental design, 36 participants were split into a control (online help) and experimental (instructor video) condition and completed five common teaching tasks in a new VLE. In contrast to most technology acceptance model research, this study found that perceived usefulness of the VLE was not related to (perceived) task performance. Perceived ease of use was related to intentions and actual behaviour in the VLE. Furthermore, no significant difference was found between the two conditions, although the experimental condition led to a (marginal) increase in time to complete the tasks.

Assessing Library Automation and Virtual Library Development in Four Academic Libraries in Oyo,Oyo State,Nigeria

The paper examines the level of library automation and virtual library development in four academic libraries. A validated questionnaire was used to capture the responses from academic librarians of the libraries under study. The paper discovers that none of the four academic libraries is fully automated. The libraries make use of librarians with background training in computer applications coupled with in-house and sponsored conferences and workshops. Again, none of the automation and internet equipments in these four institutions is assessed to be adequate. The paper recommends that parent institutions should give priority to the development of library automation and virtual library development through internet connectivity by voting adequate fund to this project.
