And I don't agree with all of the terms - and I tell the students why...
they are just a beginning... and utilizing the vocabulary, and incorporating
the elements and principles in their own work is a good place to start. I
compare it to an algorithm in math... I can tell you the steps to take to
get a correct answer when adding three digit numbers... but that's not the
only way to get there.
I teach the elements to all ages - and then use the principles in
discussions and critiquing (especially older students).
The idea of a common vocabulary continues through all subjects - elements of
writing, music etc... I tell my older kids that the elements in art are like
the elements in science (periodic table) and elements in sets in math (the
elements are the members of that set.). As for the principles - compare and
contrast in writing,emphasis/climax, movement and pattern in poetry/science
and math, definite overlap in music...
