When my son was in college, one of his buddies pointed out, “While I’m studying for a Calculus test, our friends that are elementary ed majors are cutting out shapes of construction paper for a project on sensory learning.”
When I was in grad school I taught classes in Biology. They were quite challenging classes. Our labs involved dissecting different animals and identifying their body parts. And there were experiments on the effects of different types of fertilizer on the plant life.
I spent a couple of years teaching biology labs in the education department. Their labs involved growing one plant with water and light vs a plant with no water or light. The course work looked like it came from a second grade class.
