I really thought that streaming by ability was a good idea in schools – the pupils struggling with maths would surely benefit from more time on each topic, while the gifted could soar ahead. Well, an overview (systematic review of systematic reviews)  of pedagogic variables was recently brought to my attention. The study was based on 65,000 research papers, hundreds of interventions, and 250 million pupils, by Jupiter! Anyway, it turns out that streaming by ability is completely ineffective (with the point estimate suggesting a negative effect). And what else did the overview show? I will discuss some aspects of this colossal piece of secondary research in the next exciting instalment of your News Blog.
