The Atlantic has an article on teaching science in rural areas as part of its ongoing series on STEM education. Ignore the “Left-Brain America” name of the series since that’s actually based on an old piece of pseudoscience (the left-brain right-brain terminology for different personality types has little to no basis in fact).
The article points out that like many urban districts, lack of money is a major problem for rural districts, but the effects can be different. Some schools are too small for a full complement of science courses or to get enough extra funds from grant programs. The best teachers usually don’t want to move to rural areas (the same is true in many other professions, such as medicine, where there are various programs to get people to work in underserved areas.
