I think it is a cycle. We do research to find new and best methods, strategies, innovations for teaching, and then we teach to try out those new methods and strategies. As of my current status as student-teacher, I'm more inclined to research. That is for me to further widen my choices of strategies for teaching.
The answer for me exists at two levels: the personal choice (preference) and the pressure/requirements/expectation from our surrounding context/environment/culture/institution/boss. Some countries or institutions recognize two streams of potential careers, others require academics to do both.
Personally, I am more on the teaching side, and do research either out of necessity (pressure to get publication/money) or inner drive (questions that do interest me) - occassionally, the two do match :).
When I have the chance, I try to get students (from all levels) get involved in my research projects - and vice versa: sometimes students show up with challenging ideas (or experience from work).
Right now subjects I do teach has little to do with my research projects.

From my own personal point of view, in an education and pedagogy department, we research on teaching and we teach about research too. I guess it is interesting to see what the case in other disciplines is.
