I wonder how much time I spend these days not wiping the board? Latterly, everything is projected in a sort of modern-day clanking smoking Heath-Robinson
technical adventure, and I haven’t written on the board in over a year (give or take the odd illegible scribbled table or timeline). So, no writing,
no wiping off. Time saved.
The average American, I read on the Internet, spends six months of his or her life waiting at traffic lights. Here in Britain we spend 40,000 minutes, or twenty-seven days of our life, waiting for trains or buses (which doesn’t seem that bad, in fact) and six months standing in queues. I have no idea how long my students spend rummaging through the piles of dog-eared papers we keep throwing at them, but it’s a lot.
So, I am striking off in the opposite direction. Not wiping the board saves me, I estimate, 45 seconds per lesson, which at a couple of lessons a day works out as, very roughly, six hours a year.
That’s six fat hours per annum I can spend doing other things. Logging into and out of computers, perhaps. Or more photocopying. There’s never enough time for all the photocopying I want to do.
