Education technology is often presented as a shortcut to a more modern school system. UNESCO’s 2023 Global Education Monitoring Report takes a more cautious view: digital tools can improve learning, but robust evidence of their added value remains limited and highly dependent on context.
The report highlights a structural problem for EdTech research: products change every 36 months on average, often faster than rigorous evaluations can be completed. By the time reliable evidence arrives, the platform or device may already have changed.
More technology does not automatically mean more learning
Reviews of research often find small to medium positive effects, but it can be difficult to separate the contribution of technology from other factors such as extra teaching time, teacher support or additional resources.
The problem becomes sharper when products are evaluated by the companies that make them. UNESCO argues for independent research and clear evaluation criteria before programmes are scaled.
Total cost is often hidden
Buying devices is only the first expense. Connectivity, maintenance, support, upgrades, software subscriptions, training and hardware replacement all add to total cost over time.
The report therefore recommends assessing total cost of ownership and running pilots under realistic conditions, particularly when technology is intended for disadvantaged learners.
Interoperability can reduce lock-in
When records, content and data are trapped inside incompatible proprietary systems, switching platforms becomes difficult and expensive. Interoperability standards can reduce this dependency and allow schools and universities to combine different tools.
This is a technical and policy question: control over digital infrastructure can shape learning practices, data collection and future costs.
Teachers remain central
The report does not argue for removing technology. It says technology should serve the needs of learners and teachers, not the reverse. Devices can expand access to resources, personalise practice and support collaboration, but they do not automatically replace good pedagogy.
Teacher development is therefore part of technology investment. Without digital and pedagogical skills, even advanced tools may be used superficially.
A lesson for the AI era
The GEM Report’s conclusions are even more relevant with generative AI. Rapid product cycles make it easy to introduce tools before understanding their impact, limitations and privacy implications.
The question is no longer whether technology will enter education; it already has. The challenge is determining when it creates real value, for whom and at what cost. Education innovation is therefore about evidence, governance and design, not merely buying new platforms.
