Teams should consider which level is the most effective for what they are trying to accomplish.
Level I: Least integrated; separate subjects in isolation
Level II: Material blended from disciplines within a subject area; not coordinated between subjects; possible common themes
Level III: Material kept in separate disciplines, but coordination of topics and common themes
Level IV: Few distinct discipline boundaries. Teacher teams working on one or more projects around a theme. Usually some team teaching in same room.
Level V: Most integrated; no discipline boundaries.
