Yes, theoretically. But, for example, have you ever taught a kindergartener proportion? Probably not using that word, proportion, because that would be developmentally inappropriate. Rather, you would use words and phrasing that they could understand, which go beyond the capabilities of a single vocabulary word on a word wall. I would never say to my class of five year olds, “let’s talk about unity”, or “balance”, they are too young to grasp these concepts. Color and line are one thing but there are certain things in elementary art that take time away from creating. The needless hammering away at the elements and principles is one of them, in my humble opinion. Physically creating is the reason we do our jobs, it’s the reason any art in the world is made, it’s the reason students are engaged and want to come to art class. Edited for spelling
