Over the last 100 years in teaching, how much has changed? Could you take a teacher from 1915 and drop them into a modern classroom? Apart from the strange haircuts and unfamiliar clothes they’d barely notice the difference, because the majority of school is still lecture driven. The teacher stands at the front, disseminating knowledge to the students. Now undertake the same scenario but with a surgeon. Bring a surgeon forward 100 years and it’s a different story. In a modern operating room our time traveller would be overwhelmed with sights and sounds. This is because technology has revolutionised surgery.
