I'm PhD student and I'll be graduating in May (next year). I've been getting into discipline-based educational research (DBER), including developing tools, running projects, a paper or two, and applying to grants. I do this in addition to my standard research. My DBER work is almost exclusively applications of what I develop in my (primary) research (quantitative biology).
My goal is a TT job in the future. Before going on the job market, I would like to know how hiring and tenure committees typically weigh discipline-based educational research: is it considered general research productivity, or does it typecast a candidate as primarily an educator (rather than a researcher)?
