Critical self-reflexivity is important to both ethical service-learning and equity.  But teaching it is not without its challenges, particularly in shorter-term programs and with students who are not yet in high-minimization or above.

Teaching critical reflexivity in short-term international field courses: Practices and problems. Journal of Geography in Higher Education, 39(4), 554-567.
