The University of Alaska charges in-state rates for distance graduate education for students taking FOUR units or FEWER. $301 a unit http://www.uaa.alaska.edu/futurestudents/costs/index.cfm Oddly, although I can find a list of courses at http://www.uaa.alaska.edu/distanceeducation/distance-courses/index.cfm I can't seem to find a list of degrees offered online. I know they offer a distance Master of Public Health.
Here is the list of programs offered at a distance through the University of Alaska. http://www.alaska.edu/distance/programs.html Public Health is not on this list but can be found at http://health.uaa.alaska.edu/mph/faq.htm. It does require one short visit to UAA. On a side note, my younger sister just accepted a tenure track faculty position at one of the UA campuses.
