I never mentioned making dioramas, noble. That's not the same thing at all. Some of my colleagues would do this. I hate cutting and sticking myself. But I have found, increasingly, students do just want to be 'told' things and reject working things out. This is definitely not helpful in inference subjects. It does also definitely help the brain to make connections between learning.
I could, however spend waste an entire lesson banging on about where the word diorama comes from!
I have made a zoetrope (whilst banging on about what the word means) and students ALWAYS remember that (very esoteric)word!
I think ti may be the school I work in (and it can be counter productive in some ways) but we are never told what is 'right' and what is 'wrong' teaching wise and those who wanted to do group work, or make dioramas did; those who didn't didn't.
I would say my very creative colleague who makes puppets and dioramas gets regularly the greatest number of top grades in the department.
