I've been working as a TA for an on campus program for the last year and a half. The director really likes me; she has a Masters in Mathematics and runs the learning services program for the STEM programs but she doesn't teach or do research.
I'm planning on applying to Master's in Computer Science programs and want to eventually do work in mass education programs (like Khan Academy or Coursera). Would it be acceptable to ask for a letter of recommendation from her?
I figured it would be "different" in a good way; also, any other letters would be "average" at best. I was a good student but not much more in my classes.
