Elements + Principles of Art + Design

In the undergraduate art history course I teach, students must identify the Elements and Principals of artworks.  Even when I was a student, starting in middle school, I recall this being an important ability; as my high school art teacher Mr. Mayor would say, you have to “talk the talk” if you want to be an artist.  They are vital to understand both when employing in your own artwork, and observing the work of others.  The best online resource I’ve found so far that visually and textually explain these wonderful tools is by John Lovett.
