Billions are spent on educational technology, but we don’t know if it works

By Natalia Kucirkova, The Open University

During the COVID lockdowns, schools and universities worldwide relied on education technology – edtech – to keep students learning. They used online platforms to give lessons, mark work and send feedback, used apps to teach and introduced students to programs that let them work together on projects.

In the aftermath of school closures, the market for edtech has kept on growing. The value of the sector is projected to rise to US$132.4 billion globally by 2032 (£106 billion).

The problem is that we don’t know very much about how effective many edtech apps or programs are – or if they are effective at all.

And some effects may be negative. Some of the so-called educational apps advertised to families show many adverts to children. They may use manipulative features to keep children on screens without teaching them anything new.

This technology is here to stay and will remain a significant part of how children learn – so knowing whether it works is imperative.

Assessing and addressing the quality of edtech is a significant task, especially when it is already so widely used. For edtech under development, a valuable option is to foster closer collaboration between tech developers and scientists who study learning to embed existing research and knowledge into the design.

Research consultancy firms can carry out swift assessments to provide edtech developers with information on how well what they are offering works. Transparency and integrity in the research process is vital, though, to prevent bias. Ways of ensuring this include pre-registration: reporting that a study is going to take place before it happens.

Partnerships with schools could also provide valuable feedback. However, minimum standards of quality and ethical considerations would need to be assured before technologies are sent to schools.

Setting a standard

When it comes to edtech that is already available, what is really needed is some kind of standardised metric to assess how well it works.
