The rate of spin on a ball that a golfer hits off a tee affects the distance the ball travels. Lower spin rates mean greater distance. Professional golfers hit a ball off a tee with about 2680 RPM (revolutions per minute). I hit the ball off a tee with about 3300 RPM. But I’m getting better.
I enjoy going to the golf simulator which allows me to hit a real ball into a screen – surrounded by sensors that measure the direction and spin of the ball. The incredible level of accuracy and instantaneous nature of the feedback allow me to continuously tweak and improve my swing. I’m getting measurably better, hour by hour.
Imagine if we could apply similar technology to teaching. Imagine if we could harness cutting-edge human-awareness and biometric technology to measure student engagement and to parse classroom language in real time. Imagine if a teacher could slightly tweak their methodology and get instant feedback on the effect on student engagement and learning. Imagine if, for example, as teachers experiment with different ways to ask questions, they could get accurate, live data on average student RPM (responses per minute).
Imagine if even experienced teachers were getting measurably better, lesson by lesson.
Whilst there are ethical issues still to resolve, this future is coming.
