The Big Evidence Debate – Catch Up

Featured Image

On Tuesday 4th June 2019 we held the first ever Big Evidence Debate. Leading educational experts Dylan Wiliam and Larry Hedges gave fascinating keynote presentations, and thought leaders and educational practitioners joined them to debate the contribution that meta-analysis and randomised control trials make to understanding what works in education.

The discussions sought to address some of the important challenges and explore what the profession has learned from the use of this evidence.

Contributors debated how evidence is gathered and used, reflecting on how ideas about the use of evidence have evolved over time, and discussed what this all means for the future of quality evidence-informed practice in the education community.
