We could turn back to Confucius for a way forward. He said: “I hear and I forget, I see and I remember, I do and I understand.” Hearing and seeing is what we call “lean back learning”. But doing- via problem solving – is “lean forward learning”
We should be using precious face time in classrooms for these lean forward types of teaching — to ask hard questions, to take part in interactive tasks, for guided problem solving, for working in groups and for engaging with directly and productively with teachers or tutors. Not for “talking at” students en masse.
