This article details the self-study of a beginning teacher educator in her first experience
in teaching a mathematics methods course. The transition from teacher to teacher
educator is explored through the experience of a course focused on inquiry. Inquiry is
embedded within the course from two perspectives: mathematical inquiry and teaching
as inquiry. The framework of teaching as inquiry is an important part of both the selfstudy
and the mathematics methods course. Implications of the transition from teacher
to teacher educator as well as the role of inquiry in mathematics teacher education are
discussed
