EdTech boosts learning only when paired with strong pedagogy

Published on VoxDevLit, the review; “Education Technology” offers a comprehensive synthesis of evidence on how various technology-enabled interventions affect learning, teaching, and school governance.

Laia and her co-authors argue that technology in education should be understood primarily as a delivery mechanism, not a magic bullet: what matters is not simply providing hardware, but how technology is used, what it delivers, and what it replaces. According to the review, large-scale distribution of devices such as laptops or tablets (without accompanying pedagogical changes) rarely leads to improved learning, and in some cases even results in worse outcomes.

Instead, the review highlights several types of EdTech interventions that show promising, cost-effective impact, especially when implemented carefully. Among them:

• Personalised computer-aided learning (CAL) — particularly when used as a supplement to regular instruction rather than replacing it.
• Structured video-based instruction combined with teacher support.
• Parent/teacher information systems, remote tutoring, and digital assessment tools, which can support governance, communication, and accountability in education systems.

The review also provides cautionary lessons: EdTech should complement (not substitute) traditional teaching, governance reforms, and curriculum design. Interventions need strong supervision, proper integration into school routines, and iterative adaptation to local contexts.
