The Transmission Trap: What information theory tells us about teaching
Claude Shannon’s information theory was groundbreaking. During the post-war telecommunications boom, his theory ensured that data could be transmitted over long distances without information loss. As a fundamental theory of communication, it can also tell us something crucial about teaching….

Does “checking for listening” help learning?
I’ve attended a couple of training sessions as a teacher in which the trainer would ask “check for listening” questions. They’d tell us things and then ask a question to someone chosen at random. “Seriously!?” I’d think, as the question…

The illusion of knowing the “best” teaching techniques
Recently, a claim has emerged: if leaders are frustrated with teaching outcomes, the fault isn’t the teacher, but the specific techniques (like turn and talk) they’ve been trained to use. And the proposed solution? Swap it for a different technique…

The pros of teaching without PowerPoint
PowerPoint was a central tool in the community of teachers I was inducted into. Almost everyone I knew used it to develop their lessons (or at least obtain a pre-made one). It was at once a sketchpad for planning as…

Evidence-based educational movements are actually games
Around 2012ish, a new movement rode into the UK (school) educational scene. It came with the banner of “evidence-based”, to counter the previous movement. I’m not writing to contend whether the movement was right or wrong, but to offer a…

An edu-fad’s purpose is what it does
Stafford Beer, a systems theorist, regularly claimed that a system’s purpose is what it does. There was no point claiming, he thought, that its purpose was what it consistently failed to do. In this post, I want to apply the…

Decoupling lower & upper secondary curricula
All systems exist in a constant co-adaptation with their environment. The upper secondary sections (KS4) of England’s schools are continually adapting to their communities, the government’s inspection body (e.g. Ofsted), and standardised exams (e.g. GCSEs). The demands of the standardised…

What’s the purpose of “rehearsal” during lessons?
Recently, the classroom activity “rehearsal” has appeared in UK-based educational blogs. But there appears to be confusion. What’s it for? Here are some recent quotes: Making these connections requires rehearsal Teacher: Explains, demonstrates, explains, reads, tells, explains. Then asks: ‘ok, everyone,…

Helping students develop study skills: a simple model
Advising students how to study is complex. Learning is messy, with ups and downs. Sudden insights may punctuate periods of seemingly little change. But when students are working for themselves without our guidance (i.e. at home), they need something simple…

What the variation theory of learning is and isn’t. A brief introduction.
Variation theory isn’t a theory of how memories are stored. Nor is it a theory of how learning can be impeded (like cognitive load theory); it doesn’t tell you what to avoid doing. Crucially, it isn’t just an activity or…

A model for teacher sustainability and growth
What are the most important factors for teacher sustainability? I’m sure there are many: behaviour, planning time, teaching hours, pay, etc. I’ll look at just two factors that, together, provide a rough rule for deciding whether an activity or assignment…
