In part 1 of this series of blog posts, I set out some of the recent criticisms that have been made by researchers such as Wiliam, Simpson and Slavin about the use of effect sizes to compare the impact of different interventions and the resulting problems in combining them in meta-analysis...

Since I became a researcher in the late 1990s, I have been an advocate of using effect size and meta-analysis for summarising and combining results from research.
It seems hard to imagine now, but back then, both approaches were well outside the mainstream of educational research practice and were neither widely used nor understood by most education researchers, let alone policymakers or teachers...

It has become common, although I still find it surprising, to hear teachers use the word ‘data’ as if it were a bad thing.
‘Data drops’ have come to epitomise a pointless exercise in collecting meaningless numbers and feeding them into a system that can have no possible benefit for learners. People even say that Ofsted is ‘too reliant on data’, as if a judgement process could - or should – rely on anything other than data...
