Influence of ICT Infrastructure on Teaching Performance of Academic Staff in Nigerian Public Universities

The growing deployment of digital technologies in higher education has brought renewed attention to the role of Information and Communication Technology (ICT) infrastructure in shaping teaching outcomes. This study examined the influence of ICT infrastructure on the teaching performance of academic staff in Nigerian public universities, focusing on the availability and adequacy of ICT infrastructure, its impact on teaching performance, and how access and use of ICT facilities affect instructional delivery. The study is anchored on Technology Acceptance Model (TAM), which describes how perceived usefulness and ease of use of technology affect adoption and performance. A systematic review design based on secondary data was adopted, drawing from recent empirical studies published between 2023 and 2026, with clearly defined inclusion and exclusion criteria to ensure relevance and reliability. One of the findings revealed that although ICT infrastructure is available in many Nigerian public universities, it is largely inadequate, unevenly distributed, and constrained by poor internet connectivity, unstable power supply, and limited maintenance. The findings further revealed that functional as well as accessible ICT infrastructure significantly enhances the teaching performance of academic staff by optimising instructional delivery, access to teaching resources, and student engagement, while limited access and low utilization reduce its effectiveness. It is concluded that ICT infrastructure remains a critical determinant of teaching quality, but its impact depends on adequacy, accessibility, and effective use. It recommends continuing investment in ICT facilities, equitable access across departments, and continuous capacity building for academic staff to improve utilization and teaching outcomes.
