Great potential avenue for revenue generation in Korea. Take a country with more MA’s and PhDs than academic work and deploy them in international distance education. The amount of training to transition to online teaching would be significant, but this is an area of potential growth.
Start with areas unique or, at least central to, Korea such as Korean language and culture, (East) Asian studies, and so forth and then add other programs in technology, sciences, and even humanities. I know many of you with experience in the Korean Academy will scoff, but this does have huge potential if done right.
