Ponte and Higgins developed this teacher observation protocol to monitor teachers' beliefs and practices along a continuum of professional learning. On one end of the continuum are traditional mainstream teacher beliefs and practices about teaching English language learners, and on the other end of the continuum are linguistically and culturally responsive teacher beliefs and practices. Teachers, teacher educators, professional development providers, field supervisors, and coaches can customize and use this observation protocol to gather empirical evidence of teacher learning over time.
