I wanted to look at degree programs related to education and TESOL but slightly different.
This Vanderbilt PhD has a strong focus on literacy but also works with oral communication and ESL.
UMBC Masters in Intercultural Communication - 2 year program with or without thesis that offers no assistance for native English speakers.
The university of Florida has one but their website offers relatively little information. You can see how the 34 credits required break down by checking out the pdf.
Hawaii has an MA in Communication with specializations like global communication, organizationa & intercultural communication, etc.
UMass has a program that leads to an EdD in International Education - specifically improving it in developing countries.
I also searched for Intercultural Studies but many results were for religious things and I gave up on that one.
This George Mason PhD in cultural studies sounds interesting.
Interesting article here about a UW class on Liave Action Roleplaying. I've actually done this so it may be more interesting to me than to people who have no idea what it is, but it certainly doesn't seem like an academic discipline.
I could be wrong though. The professor tries to spin it academically:
“My goal is to think about how games can be analytical and critical, how games can tell us about the world around us,” Chang said. “One goal of the class is to realize that live-action has a stigma. It’s about challenging those stereotypes and realizing how live-action games tells us about the different roles and personas we play in real life.”
And there is a reading list on the course page. Still the fact is they are playing a game once a week not unlike the LARP I've done (I assume).
