As an instructor myself, I'm always looking for ways to improve my storytelling, since that's the key to good teaching. People have different learning styles, i.e. some learn best by reading, hearing, some by doing, some by looking at diagrams and charts and such. So, online learning can be very effective for some. Here's a website with a free learning style test, if anyone is interested: http://www.vark-learn.com/english/index.asp
I'm also reading a good book on Storytelling right now. Here's a link to that: http://www.amazon.com/Improving-Your-Storytelling-American-ebook/dp/B001TH84D8/ref=sr_1_2?ie=UTF8&qid=1329545029&sr=8-2
As for the cost, financial aid is available. Since it is a graduate program, it is not funded by Pell Grants, but by University funds, which are given out on a "first-come first-served" basis. They usually run out mid- to late- June, but those who apply before that are highly likely to get them. (The financial aid official I spoke with said that income is not usually a determining factor in who gets the funds at the graduate level) If you do get grants, you need to take a minimum of five credit hours per semester.
I'll let anyone interested know after the classes if I thought they were worthwhile.
