Check out Jennifer Hartman's blog which is providing a forum for contributors in different arts disciplines: theater, music, dance and visual art. A grad student at the University of North Texas (my alma mater!) is working on a blogging project for a multimedia class. Visit her blog and make a comment!
I am really excited about other teachers using the blog as a virtual classroom! Free, convenient, and easily accessible, it is an excellent tool to use with students in the classroom. You can check out her blog in the blog title or in the blog list on the right. Good luck Jennifer!
