Stale Ph.D.'s Need Not Apply - Graduate Students - The Chronicle of Higher Education

A few years ago I talked to a person with a Ph.D. in math education who, despite working at a university teaching methods courses to preservice math teachers, assumed that after 3-4 years of being away from research he was no longer marketable for a tenure-track position at a research university. That's troubling. People like that might be a little behind on the cutting edge of the research, but that kind of catching up might be easy compared to the value gained from teaching several years of methods courses or having other relevant experiences.
