Research can't tell teachers what to do—classrooms are too complex for that ever to be likely. But research can identify "best bets" for improving practice, and the Great Teaching Toolkit Evidence Review is pretty much the state of the art in this regard: greatteaching.com

Sometimes, a graph is so eloquent that commentary is superfluous: bit.ly/2dYFr7O

Now this is very interesting, and I don't think at all obvious. Reading challenging texts aloud, and at a fast pace, improved the reading comprehension of all students, but for the lowest achievers, the gains were almost twice as great: bit.ly/2XUMfp0.

Poorer adolescent readers are often regarded by teachers as unable to read whole narratives and given short, simplified texts, yet are expected to analyse every part in a slow laborious read-throug...

I have uploaded around 40 Powerpoint presentations that I have made for research studies I have read over the last couple of years, and they are available here bit.ly/DWiliamPP under a Creative Commons Attribution (CC BY) license. I will add more when I get time.

328 studies over 50 years show that direct instruction (structured guidance for teachers, teaching discrete skills before application, daily checks on learning, regular testing for mastery) has consistent, large positive effects on student achievement: bit.ly/2Leaaxl ($)

A meta-analysis of 64 studies finds that self-explanation (e.g., asking students "Could you explain this to someone else") during instruction has a substantial impact on learning (g~0.55): bit.ly/2BzVZMA ($)

This may be the most important blog post I have read this year: "Your brain does not process information, retrieve knowledge or store memories. In short: your brain is not a computer."

A study of 355k UK primary school students finds reading achievement in one year predicts maths achievement the next year more strongly than the other way round suggesting "acquiring good reading skills is highly relevant for developing mathematics skills" bit.ly/3OYL2I5

Just realized that I've never tweeted a link to the IES's 2007 Practice Guide on "Organizing instruction and study to improve student learning": bit.ly/3jLEzQk. The checklist makes a much better placemat than most of the quick reference guides offered to teachers.

A rare kind of study in education: a ten year follow-up of the long-term effects of Reading Recovery shows that the benefits are large, and the programme is highly-cost effective (£1 spent has a societal benefit of over £3): bit.ly/2Uo0K3e.

Why value-added is useless for measuring teacher quality: good teachers develop non-academic qualities that do not show up in that year's test scores but are crucial to longer-term success: bit.ly/2zEwoSg (pdf)

A review of research on "flipped" classrooms finds that there is little evidence either way about impact on student achievement, and most studies are so poorly theorized that studies are difficult, if not impossible, to compare: bit.ly/2JarNvz

I've just uploaded 3 short (~20 minute) videos on "Why we need to raise achievement", "What formative assessment is, and isn't", and "Teacher learning communities" to my YouTube channel: bit.ly/DWiliamYouTube. As ever, they are available under a @creativecommons CC-BY license.
