An education concept defining a learning, teaching, or organizational practice used to develop knowledge and skills. It applies when prerequisites are met and produces observable changes in learner performance or organizational capability. It does not ensure outcomes without appropriate implementation, feedback, and adjustment based on evidence. It materially affects learning and equity by shaping access, quality, and effectiveness of educational experiences. The concept is generally stable, though standards, tools, and research evidence evolve over time.

Principle

The organizing idea is to remove barriers to access and permission by using explicit open licences and modular formats so resources can be adapted, redistributed and combined to meet diverse learning needs.

Demonstration

A university publishes a textbook under a Creative Commons licence; teachers adapt chapters for local curricula, students download and print individual modules, and a school district remixes exercises into a bilingual packet.

Misapplication

Labeling paywalled PDFs or copyrighted slides as OER without a license that grants reuse and adaptation, or distributing materials that prohibit modification while calling them 'open'.

Consequence

When applied correctly, OER reduce cost barriers, increase availability of curricular materials, accelerate pedagogical innovation, and enable locally relevant adaptation while requiring attention to quality and maintenance.

Reversal

Closed educational materials are proprietary texts, licensed for limited use, distributed behind paywalls, and legally restricted from being modified or redistributed.

Boundary

OER exclude materials that are not accompanied by an open licence permitting reuse, adaptation or redistribution; they also exclude resources behind access controls or subscription paywalls even if freely viewable in limited contexts.

Semantic Tension

There is tension between 'free' as zero price and 'open' as freedom to reuse and adapt; a resource can be free to read but not open to adapt, creating ambiguity unless licence and permissions are explicit.

Synthesis

Open Educational Resources are openly licensed, modular teaching and learning materials designed to be freely accessed, adapted, and shared to expand equitable access and enable local pedagogical customization while requiring governance for quality and sustainability.
