It is believed that arts education helps teach children to communicate well with adults and friends. It also helps them get personally involved in increasing the amount and quality of arts education. You can go to http://www.danceadvantage.net/ for more information.
It doesn't. I don't understand why colleges are doing that sort of thing. Art classes are not that important and if they want people to learn how to communicate with adults, then I don't think art will be the best way.
