REIMAGINING SCHOOL EFFECTIVENESS IN THE DIGITAL ERA: THE MEDIATING ROLE OF TEACHERS' DIGITAL COMPETENCE IN DIGITAL INSTRUCTIONAL LEADERSHIP IN NIGERIA

Abstract

The rapid digitalization of education has transformed the leadership responsibilities of school principals and redefined expectations for effective school management in the twenty-first century. As educational institutions increasingly adopt digital technologies to support teaching, learning, communication and administration, principals are expected to function as digital instructional leaders capable of guiding technology integration and fostering innovation. Despite growing investments in educational technologies, school effectiveness remains a concern in many developing countries, including Nigeria. This conceptual paper, based on a purposive narrative review of peer-reviewed literature published between 2017 and 2024 and accessed through Google Scholar, ERIC and ResearchGate, examines the relationship between digital instructional leadership and school effectiveness. It argues that teachers' digital competence serves as the critical mediating mechanism through which leadership practices influence educational outcomes, a claim grounded in Baron and Kenny's (1986) causal steps framework for mediation analysis. Drawing on Transformational Leadership Theory, Instructional Leadership Theory and the Technology Acceptance Model, the paper synthesizes contemporary literature on digital instructional leadership, teachers' digital competence and school effectiveness. The paper contends that principals who promote digital vision, instructional supervision, data-driven decision-making, effective communication and professional development are more likely to cultivate digitally competent teachers. Such competence enables teachers to integrate technology effectively into pedagogical practices, thereby enhancing instructional quality, student engagement, academic achievement and overall school effectiveness. The paper proposes a conceptual framework linking the three constructs, highlights implications for educational leadership and policy and calls for future empirical research to test the proposed mediation model in Nigerian secondary school contexts.
