Dear golly, YES! But it really takes money.
In times of budget cuts, many teachers cut back on things that kids love, and the arts is a really big field to cut cost corners on.
Here's a good idea for schools to incorporate the creative arts. Singing songs related to the curriculum is a cheap idea. They don't need a program that encourages singing in non-music classes. All they need is to make up song parodies to songs kids know. One French class sang a song on the terms for the days of the week to the FLINTSTONES theme.
Hey, I'm no Howard Goodall, but I would like to see teachers singing songs about the subject matter to kids and them singing along. This method helps them retain the lesson learned more and still expose them to the arts.
Another way I see an activity that places more emphasis on the creative arts is to assign interactive notebooks. Those are notebooks which they can decorate and still write their notes. I had done this in middle and high school social studies classes and I got good grades on them since.
Arts programs aren't free, but incorporating the arts in a way that fit both budget and practical curriculum does.
