OER Impact Analysis

Introduction to OER and Impact

What is OER?

Open Educational Resources (OER) are teaching, learning, and research materials that are freely accessible and openly licensed. They can include textbooks, course readings, videos, simulations, and assessments. By removing cost barriers and enabling adaptation, OER supports more inclusive and flexible learning environments. The openness also allows educators to tailor content to local contexts, cultures, and languages.

Why analyze impact?

Analyzing impact helps policymakers, institutions, and educators determine whether OER investments deliver their intended benefits. It clarifies how OER influences access, learning experiences, and outcomes while revealing trade-offs and implementation challenges. Systematic analysis also supports evidence-based decisions about licensing, funding, and quality assurance.

Key metrics and indicators

Impact evaluation commonly tracks a mix of economic, learning, and equity indicators. Core metrics include:

• Student cost savings and affordability trends
• Access and enrollment or completion rates
• Learning gains, exam pass rates, and knowledge retention
• Engagement, persistence, and time-to-degree indicators

Additional indicators address accessibility, licensing clarity, and sustainability of OER initiatives. A balanced set helps connect inputs and activities to outcomes in diverse contexts.

Scope and Methodology

Study scope and definitions

This analysis examines postsecondary and professional learning contexts where OER adoption has demonstrated measurable effects. It defines OER broadly to include openly licensed textbooks, courseware, and ancillary materials that are freely accessible online and legally reusable, remixable, and redistributable. The scope emphasizes regional diversity and varying institutional sizes.

Data sources and study design

Findings draw on multiple data sources, including institutional procurement records, student surveys, course analytics, and case studies. Where possible, comparisons use matched cohorts or pre/post designs to isolate potential OER effects. The design prioritizes transparency and replicability to support cross-context interpretation.

Evaluation metrics and comparators

Evaluation pairs outcomes with appropriate comparators, such as previous textbook adoption, traditional course materials, or alternate open resources. Metrics span cost, access, engagement, and learning outcomes, with attention to confounding factors and baseline differences.

Economic Impact of OER

Cost savings for learners

OER can substantially reduce the direct costs of course materials for students. When learners access free or low-cost alternatives, they are more likely to enroll in required courses, persist through deadlines, and complete programs. The magnitude of savings varies by discipline, institution, and student population, but even modest reductions in material costs can influence enrollment behavior and equity.

Cost savings for institutions and systems

Institutions experience cost offsets through reduced licensing fees, the reuse of existing materials, and lower printing or distribution expenses. In some cases, OER lowers total cost of ownership for program resources and enables rapid curriculum updates without the expense of revising proprietary texts. However, initial adaptation and faculty development require upfront investment.

ROI and funding considerations

Return on investment for OER hinges on factors such as adoption scale, faculty engagement, and ongoing maintenance. ROI calculations should account for materials savings, satellite costs for training, and potential improvements in retention and outcomes. Sustainable funding models—such as grants, shared repositories, or institutional funds—are essential to sustain updates and quality assurance.

Educational Outcomes and Learning Gains

Evidence on learning outcomes

Evidence on learning outcomes with OER is mixed but often positive in targeted settings. In several cases, OER-enabled materials achieved learning gains comparable to or exceeding those of commercial texts, especially when aligned to course objectives and supplemented with high-quality assessments. Gains are more likely when instructors actively curate and contextualize open materials.

Influence on engagement and persistence

When course materials are affordable and accessible, student engagement tends to improve, with higher attendance, more hours devoted to study, and greater persistence in challenging courses. Open materials can also support collaborative learning through shared resources and community-driven improvements, contributing to a stronger sense of course ownership.

Assessment alignment and quality

Quality assurance for OER often focuses on alignment between materials and learning outcomes. Clear learning objectives, up-to-date content, and robust assessments are critical. Open licensing facilitates local adaptation of assessments to reflect curriculum changes, while shared quality standards help maintain consistency across institutions.

Access, Equity, and Inclusion

Addressing the digital divide

OER has the potential to expand access by removing material costs and enabling offline or low-bandwidth options. However, successful deployment requires reliable device access and internet connectivity. Initiatives that provide offline formats, campus computer labs, and low-tech alternatives help mitigate the digital divide.

Accessibility and accommodations

Accessible OER meets universal design and accessibility guidelines, ensuring materials work with screen readers, captions, and assistive technologies. Inclusive authoring practices, alternative text, and accessible formats broaden participation for students with disabilities and diverse learning needs.

Equity across regions and demographics

Impact varies by region and demographics due to differences in infrastructure, language, and educational ecosystems. OER that prioritizes multilingual content, context-relevant material, and local partnerships tends to support greater equity, particularly in underserved communities and rural areas.

Policy Implications and Design

Licensing and openness

Open licenses—such as Creative Commons—clarify reuse rights, versioning, and attribution. Clear licensing accelerates adoption, enables modifications, and protects authors. Policies that promote openness while preserving quality control help sustain a vibrant, reusable ecosystem.

Sustainability and funding models

Long-term sustainability requires diverse funding streams, including institutional allocations, consortia, grants, and community-supported repositories. Regular funding for curation, updates, and quality assurance ensures that OER remains current and reliable across disciplines.

Quality assurance and standards

Quality standards establish credibility and trust. Standards may cover content accuracy, alignment with learning outcomes, accessibility, and interoperability. Transparent review processes and version control enable instructors to select reliable materials with confidence.

Case Studies and Regional Perspectives

Regional highlights

Across regions, OER adoption reflects differing priorities and constraints. Some regions emphasize textbook replacement to reduce material costs, while others focus on open courseware for modular, credit-bearing components. Regional collaborations often amplify impact through shared repositories and joint professional development.

Contextual factors and transferability

Transferability depends on language, policy environments, and infrastructure. What works in one university context may require adaptation elsewhere. Successful transfers typically include stakeholder engagement, local content adaptation, and supportive accreditation pathways for open materials.

Best practices from implementations

Effective OER implementations share common practices: engage faculty early, provide professional development on open pedagogy, establish sustainable maintenance plans, and create easy-to-navigate repositories. Measuring outcomes early and iterating based on feedback accelerates impact while preserving quality.

Methodological Challenges and Data Considerations

Data gaps and measurement limits

Data gaps may include inconsistent reporting, limited longitudinal data, and challenges linking materials to outcomes. Overcoming these gaps requires standardized data collection, clear definitions, and open data sharing where possible.

Attribution and causality

Attributing outcomes to OER versus other factors (instructional design, teacher effects, or student support) is difficult. Robust designs use control groups, pre/post measures, and triangulation across data sources to strengthen causal inferences.

Replication and generalizability

Findings from one context may not generalize. Replication across disciplines, institutions, and regions helps identify which OER strategies are most effective and under what conditions. Transparent reporting supports comparative analyses.

Recommendations and Best Practices

For policymakers

Policymakers should encourage open licensing, support funding for sustainable OER maintenance, and require transparent evaluation reporting. Policies that promote collaboration, shared repositories, and quality standards can scale impact while maintaining accountability.

For educators and institutions

Educators are advised to curate and contextualize OER to align with outcomes, engage students in material development, and participate in professional networks for open pedagogy. Institutions should invest in training, repository infrastructure, and ongoing content updates to sustain quality.

Future research directions

Future research should deepen causal analyses, explore long-term learning and labor market outcomes, and examine equity effects across diverse populations. Studies that integrate cost-benefit models with learning analytics can provide richer insights for decision-makers.
