„In Shanghai (China), teaching is both considered and actively developed as a collaborative profession. Schools are organised to facilitate daily interaction among teachers, with collaboration seen not as an add-on but as an essential part of their work. One of the key enablers of this model is a limited teaching load: teachers typically spend just 12 hours per week in the classroom, leaving ample time for joint activities, such as lesson observation, co-planning, and mentoring.“
