At the recent ResearchEd 18 event in London we learned all about instructional coaching, which is, according to researcher Sam Sims, “probably the best-evidenced form of CPD currently known to mankind”.
The evidence he presented was both convincing and compelling. Looking at randomised-controlled trials of teaching interventions in English (from the US-based Investing in Innovation programme) only seven out of 31 had a statistically significant positive effect, with even worse results for maths (three out of 23).
Of the 15 RCTs Sims found on instructional coaching, however, ten had a statistically significant positive effect.
So what is instructional coaching, how does it work and how can your teachers benefit from it?
