Reimagining Higher Education through Open Educational Resources: A Comprehensive Review

Overview

This systematic review examines the role of Open Educational Resources in higher education from 2015 to 2026, focusing on their conceptual foundations, components, integration requirements, usage patterns, impact, and adoption challenges. The review positions OER as transformative tools that promote accessibility, affordability, and pedagogical innovation within higher education institutions. The study synthesizes findings from peer-reviewed literature to assess how OER, operating through the 5Rs framework of retain, reuse, revise, remix, and redistribute, function as mechanisms for enhancing educational equity and institutional sustainability. The analysis encompasses various OER formats including open textbooks, full courses, multimedia resources, and interactive modules, examining their collective contribution to reshaping higher education delivery models.

Methods and approach

The review employed systematic literature retrieval from four academic databases: Scopus, Web of Science, Taylor & Francis, and Google Scholar. The search covered an eleven-year period spanning 2015 to 2026. Following initial retrieval, studies underwent screening and eligibility assessment procedures, resulting in the inclusion of 36 peer-reviewed studies in the final analysis. The review framework examined six primary dimensions of OER implementation: conceptual foundations, resource components, integration requirements, usage patterns across institutions, measurable impact on educational outcomes, and barriers to adoption. This multidimensional approach enabled comprehensive assessment of OER ecosystems within higher education contexts.

Key Findings

The review identified that OER formats ranging from open textbooks and complete courses to multimedia and interactive modules demonstrably enhanced student engagement, academic performance, and educational equity. These outcomes were attributed to the operational framework of the 5Rs: retain, reuse, revise, remix, and redistribute. However, the analysis revealed significant implementation constraints including faculty resistance, limited institutional awareness, inadequate technological infrastructure, fragmented repository systems, and insufficient policy frameworks. These barriers collectively impeded systematic OER integration across higher education institutions. The findings indicated that successful OER adoption required coordinated interventions across multiple institutional domains rather than isolated technological or content initiatives.

Implications

The review establishes that effective OER implementation necessitates comprehensive institutional strategies encompassing policy mandates, targeted professional development for faculty, quality assurance protocols, and sustained technical infrastructure investment. The findings suggest that strategic, policy-driven adoption frameworks position OER as foundational components of inclusive, sustainable, and innovation-oriented higher education ecosystems rather than supplementary resources. The identification of persistent barriers including resistance, awareness deficits, and fragmented systems indicates that OER transformation requires coordinated institutional commitment extending beyond resource availability to encompass cultural, procedural, and structural institutional change. The review positions OER adoption as integral to institutional capacity for addressing accessibility and equity imperatives within contemporary higher education.
