AbstractTeacher educators are typically involved in preparing preservice teachers (PSTs) in initial programs through teaching courses and supervising practicum experiences, including the culminating student teaching practicum. Using self‐study of teacher education practices (S‐STEPs) during supervision, the authors describe a scaffolded process of learning to supervise teacher candidates and engage in reflections about their experiences working collaboratively. This narrative account by a more experienced supervisor and a new supervisor uses samples of feedback to teacher candidates to demonstrate a collaborative process based on multimodal observational field notes, which included sample discourse from the classroom to exemplify interactions, teaching activities, and photographs of classroom activities. Both researchers participated in joint meetings with (1) PSTs to discuss feedback, (2) mentor teachers to discuss progress of PSTs, and (3) all PSTs to discuss themes that emerged from observations and assessments, something unique to this collaboration. The authors discuss how their collaboration led to curriculum changes to a TESOL methods, curriculum, and assessment course influenced by observations in the field. The article concludes with implications and recommendations for other teacher educators interested in collaborative supervision.
