The "Teaching for Robust Understanding" (TRU) framework was designed by a Schoenfeld-led group at Berkley and Michigan State. Its purpose is to shape the ways in which classroom environments are structured, as outlined by 5 dimensions: (1) the content, (2) cognitive demand, (3) equitable access to content, (4) agency, authority, and identity, and (5) uses of assessment.
