In a typical system, teachers work in isolation with minimal access to content-specific expert support. Teacher teams do not examine student work and other data consistently to improve instruction, and most professional learning happens outside the context of teachers' daily work.
With Strategic School Design, teacher collaboration is the engine for school improvement and the way to lighten teacher load. Teaching teams, led by instructional experts (often teacher leaders) meet regularly to plan and adjust instruction based on student data. Content-specific experts support team meetings, observe and coach teachers, and collaborate to improve their own effectiveness as coaches.
