I recently spent a day at a secondary school in Birmingham. I agreed to do it because I like being in Birmingham and I like going to schools, and also because the teacher asked nicely. It was only the day before that I read the invitation properly and saw, to my horror, that I was leading what they call a Deep Learning Day. What could they learn from me? Moreover, what could they learn deeply from me?
Whenever I go to schools, I always come away feeling that I’ve learned a lot more from the experience than any students have learned from me. This visit was no different. I came away enriched, but also completely knackered. I’m in awe of the stamina not only of teachers, but also of students. I mean, a whole day of learning, deep or otherwise, is exhausting. Whichever side of it you’re on, it’s a lot.
A notice on the staffroom wall jumped out at me. Apologies to any teachers reading this, for whom the following might well be a hoary old maxim they’re tired of seeing. It went as follows: Learners remember 10% of what they read; 20% of what they hear; 30% of what they see; 50% of what they see and hear; 70% of what they discuss with others; 80% of personal experience; 90% of what they teach someone else.
This all sounds about right to me, dispiriting as it is for someone who earns a crust writing things for people to read, and talking about things on the radio, only to find out that 90% of the former and 80% of the latter aren’t recalled at all. That’s a lot of wasted ink and keyboard taps and airtime. Disappointing. Disappointing too, for someone who used to present a lot of television, to read that what you see and hear at the same time scores rather better. Though I don’t much miss working on television, I do occasionally feel the need to tell myself that radio and writing are nobler arts which linger longer than television in the minds of the audience. Hmm. Not according to this they don’t.
The high scorers here are fascinating too. They rather explain the power of the modern echo chamber. If 70% of what you discuss with like-minded people sticks, as well as 80% of your personal experience – what’s become known, without irony, as “your truth” – you can see how your truth becomes the truth. And then there’s the strikingly high 90% recall you have of the point of view – valid or otherwise – that you’ve so diligently inflicted on others. Bit negative all this, I appreciate, but there you go. Every day’s a school day.
