Many teachers simply teach crafts and dont dive into the complex world of art and expression. A dedicated classroom would provide students with the appropriate work place including supplies, space, and atmosphere. Finally, students would benefit greatly from being taught by someone with a degree, someone who could instill a love of art.
There are many creative students and students who like drawing, origami, and crafts. I personally like using cardboard and tape to make phones, watches, machines, and all kinds of things. This also helps students improve in studies, because they can learn how to be precise in making things, and how parts fit together.
