Self-regulated learning (SRL) is a fundamental skill for school and life. Much is known about how to effectively teach and support it in a classroom, though teachers often retreat to more structured, external learning regulation. Experts have identified the important role of pedagogical knowledge and personal self-regulated learning in helping teachers persevere with SRL teaching attempts. Teacher training programs target these specifically with pre-, post-, and concurrent learning experiences, and the act of carrying out regular SRL-oriented conversations with students itself fosters these insights and wisdom. In this article, the authors explore the way a structured, socially shared protocol for learning regulation support (SSLR) can increase teacher adherence to -- and learning from -- SRL-supportive teaching practices. They present qualitative interview data gathered from 12 users of an SSLR intervention to characterize the in-service learning and growth that the use of this approach may enable.
