Collegial learning (kollegialt lärande) means that teachers work systematically together to develop their teaching. This can take the form of co-assessment, lesson observations, joint planning, or discussion of research and proven experience.
Forms
Common forms include Teacher Learning Communities (TLC), Lesson Study, subject teacher meetings, and mentoring. The National Agency for Education's professional development programmes (the Maths Boost, the Reading Boost) rely heavily on collegial learning as a method.
