In our paper we describe a newly developed teacher coaching model that provides training on motivational interviewing (MI) to improve instructional coaches' effectiveness with classroom teachers. Participants were 38 coaches who completed a three-day coaching training. At pre- and post-test, the participants completed role plays with an actor who played the role of a new teacher. Then, these sessions were coded for MI-consistent behavior. The results of our study revealed that the majority of the coaching conversations were inconsistent with effective MI. At baseline, conversations were primarily characterized by questions (60%) followed by attempts to persuade without permission (20%). Following training, coaches did not change their conversational style. Because an MI-inconsistent conversation style is associated with decreased self-efficacy and motivation for change, the findings suggest a need to help coaches develop interactions that are more consistent with best practices of MI.
