Before music teachers can effectively implement Social-Emotional Learning (SEL) with students in the classroom, they must develop their own SEL skills and tend to their personal well-being. This practical guide takes teachers through 13 sequential units designed to hone important self-care and SEL skills, such as regulating emotions, resolving conflict, managing stress, and building positive relationships. Each unit is structured around the three core pillars of SEL: Identity, Belonging, and Agency. It guides teachers through a series of thought-provoking exercises to strengthen their skills as well as giving them space to discover, reflect, journal, draw, and commit to growth. An essential resource for current or future music teachers, and ideal for professional development, this handbook can be used year after year to guide teachers on their journey to SEL competency and personal well-being.
