When I became a teacher, it wasn't long before I realized that even the most obvious, explicit instructions, would lead to a varied outcome. Pretty much the shape of a bell curve, 60% of the kids would understand reasonably enough. But 40%, would see things I though only existed in alternative universes or maybe Bizzarro World. And that 40% would be all over the place.
OK I told myself, they are kids.
When I became a principal, teachers acted exactly the same. Even having asked clarifying questions and having knowledge the kids don't have, made no difference.
SO, in Sum, nothing is obvious and when you are sure it is; it isn't.
