Defining the claim
“Revolution” suggests a rapid, deep change in how a system works, with old arrangements replaced by new ones. If open education were a revolution in education, we would expect to see schools and universities restructured, how people qualify and learn altered at scale, and the old providers displaced. This article tests the claim against what can reasonably be observed, and does not rely on any statistics invented for effect. Where numbers are lacking, it says so.
Tests for a revolution
A fair set of tests might be:
- Scale. Is a large share of teaching or learning now done differently?
- Depth. Have the core functions of schooling, such as instruction, assessment and certification, changed?
- Replacement. Have established institutions been displaced?
- Outcomes. Do learners achieve more, or have access they lacked before?
- Speed. Did the change occur quickly?
What the evidence supports
Scale: modest and uneven. Openly licensed materials are used by many teachers and institutions, and open textbooks are now an accepted option in some systems. But most teaching worldwide still relies on conventional textbooks, teacher-prepared materials and commercial products. Where adoption has grown, it is often concentrated in particular courses or regions.
Depth: partial. Some practices have changed, such as how materials are sourced and shared. Core functions have changed little. Classes are still largely taught by teachers to groups, assessment is still mostly institution-run, and degrees are still issued by the same kinds of bodies.
Replacement: not evident. Universities and schools have continued to operate. Large free online courses attracted attention in the early 2010s and were sometimes predicted to displace traditional universities. That has not happened in any broad sense; the courses found a role alongside existing institutions, and many providers adapted by adding paid certificates and degrees.
Outcomes: mixed. Studies that compare students using open textbooks with those using conventional ones often find similar performance, with a clear difference in cost. Evidence about wider learning gains is inconclusive. Access to materials has improved for some learners, but large groups remain excluded by connectivity, language and circumstances.
Speed: gradual. The main milestones, from the first open courseware publication in 2002 to the 2019 UNESCO recommendation, spread over nearly two decades. Remote teaching during 2020 was a sudden change, but it was an emergency response and not a planned shift to openness.
What did change substantially
It would be wrong to conclude that nothing has changed. Several things have:
- Legal clarity for reuse. Standard open licenses did not exist in 2000 and are now routine.
- Cost options for students. Free textbooks are a realistic choice in many subjects.
- Public availability of university-level materials. Millions of people have used free online courses and materials.
- Policy attention. International and national bodies now discuss open licensing as a policy tool.
- Cultural change in some teaching communities. Sharing has become more normal.
These are significant, but each is a change within the system, not a replacement of it.
Why revolutions are claimed
Several motives explain the language. Advocates want attention and funding. Journalists favor dramatic framings. Technology companies promote products. Funders want transformative impact. None of these motives requires the claim to be true, and some of them reward exaggeration.
Why change is gradual
Education is slow to change for good reasons. It involves large institutions with established rules, employment contracts, accreditation, exam systems and public expectations. Teachers need time to learn new methods. Parents and employers trust familiar qualifications. Funding cycles are long. A change in one part, such as the price of textbooks, does not force changes in the rest.
Gradual does not mean unimportant. Slow changes accumulate, and a decade of steady adoption can reshape practice more than a headline-grabbing event.
Reading future claims
When you meet a claim that open education is, or will be, a revolution, ask:
- What exactly has changed, in whose practice?
- How is it measured, and who did the measuring?
- What is the comparison point?
- What would have to be true for the claim to be false?
Claims that cannot be tested are rhetoric, not evidence.
A fair conclusion
On the evidence, open education is better described as a significant, gradual reform than as a revolution. It has changed some costs, some rules and some habits, and it has widened access for some people. It has not displaced schools or settled the problems of motivation, support, equity and recognition. That is not a disappointing result. Reforms that last often look modest year by year and substantial over decades. The more useful approach is to support what works, measure honestly and adjust, without waiting for or promising a revolution.
