THE EFFECT OF AI-POWERED POWERPOINT PRESENTATIONS ON NIGERIAN TERTIARY INSTITUTION LECTURERS’ WORKLOAD AND PRODUCTIVITY

Abstract

This study investigates the impact of AI-powered PowerPoint tools on workload and productivity among university lecturers in Nigeria. Using a quantitative survey design, data were collected from 216 lecturers across Nigerian tertiary institutions, with 126 below 45 years and 90 above 45 years of age. The research examined the extent of workload reduction, age-related differences in adoption and perceived effectiveness AI-powered PowerPoint, and the relationship between AI tool use and self-reported productivity. Results indicate a significant reduction in presentation preparation time for AI tool users (5.2 hours/week) compared to non-users (8.7 hours/week). A notable adoption gap was observed between age groups, with 72% of younger lecturers using AI tools compared to 41% of older lecturers. However, perceived effectiveness did not differ significantly between age groups among users. A moderate positive correlation (r = .42) was found between AI tool use frequency and productivity measures, including increased presentation output and research publications. The study reveals promising benefits of AI-powered tools in alleviating workload and enhancing productivity in Nigerian higher education. Recommendations include implementing comprehensive training programs, addressing age-specific adoption barriers, and developing strategies to ensure equitable access to these technologies across faculty demographics.
