Screencast is a digital video and audio recording of what occurs on a presenter's computer screen which gives learners the chance to control the pace at which they learn; thereby influencing their academic performance positively. Despite these benefits of screencast in enhancing teaching and learning in distance learning programmes, they are being adopted in Nigerian higher institutions. The research adopted the mix-method approach, using quantitative and qualitative data analyses with 50 undergraduates forming the sample for the study. Two research instruments were used to gather data in the study, namely Educational Technology Achievement Test and Screencast Attitude Questionnaire. The former was tested using split-half reliability statistics and yielded a value of 0.727, while the latter was subjected to Cronbach’s Alpha reliability statistics and yielded a value of 0.662. The research questions were answered using mean while research hypotheses 1-3 were tested using AN-COVA. Findings of this study showed that: (i) there was significant difference in the performance of the experimental and the control group in favor of the experimental group; (ii) there was no significant difference in the mean score performance of male and female undergraduates exposed to screencast; (iii) the undergraduates that were exposed to screencast had positive attitudes toward the use of podcast; (iv) there was significant difference in the retention-test performance of the experimental and the control group in favour of the exper-imental group. Based on the findings, it was recommended that courseware developers should develop and utilize screencast to supplement course materi-als.
