Self-regulated learners manage their thoughts, emotions, and behaviours, and their social and contextual environments to reach their learning goals. Research shows that student teachers can learn to teach in ways that promote students' development of SRL. It has also been shown that there is a relationship between teachers' own SRL and their ability to develop self-regulation in students. This study examined student teachers' developing concepts of SRL as they learned about this complex set of skills, behaviours, and beliefs through both coursework and field observations. This paper investigates the relationship between self-reported SRL of these teachers and their understanding of SRL behaviours and SRL-supportive teaching practices. Participants' self-reported learning strategy scores predicted their performance on an SRL classroom observation assignment while motivation scores were unrelated. These results contribute to our growing knowledge of how to support student teachers in their learning of teaching strategies that support the development of SRL.
