Exploring the use of effect sizes in education research

In this video, we hear from Gemma Goldenberg and Dr Sam Sims as they discuss the use of effect sizes in education research.

Key learning points:

• Effect sizes have only relatively recently emerged in research engaged with in schools due to work from John Hattie, the Education Endowment Foundation and others
• The different ways in which significance is measured can make it challenging to engage with and understand effect sizes
• Implementation and its associated challenges can make it hard for schools to put into place interventions that are seen to have a high effect size
• The effect size should be considered alongside our other judgements of the reliability, trustworthiness and usefulness of the research study
