All interviewees voluntarily participated in the OAE course and interview. This, along with
the fact that some participants were interviewed by their former instructor, and that we selected
interviewees known to be more reflective, potentially biases responses in favor of those who had
a more positive or meaningful experience. Overall, our sample is not representative, but rather,
consistent with the purposes of qualitative research (Patton, 2002, Maxwell, 1996), a collection
of useful perspectives to allow deeper understanding of the OAE experience and to suggest new
directions for further research
