Each chapter offers four perspectives on each methodology (1) theoretical groundings of the genre (2) research-based evidence on methodologies-as-pedagogies for mediating teacher learning (3) mediation tasks for teacher education as reported in studies and (4) a synthesis of recurrent themes identified from selected books and articles, including a comprehensive list of publications organized by decades. The last chapter presents an integrative framework that conceptualizes connections and weak links across the different methodologies of mediation.
