Alan H. Schoenfeld

Alan Henry Schoenfeld (born July 9, 1947) is an American mathematics education researcher, consultant, and theorist.

[1][2][3] Schoenfeld's work ranges widely across thinking, teaching, and learning in mathematics and beyond, with particular interest in methodological issues aimed at improving the effectiveness of educational research.

Since the 1990s Schoenfeld has become increasingly focused on the challenges of translating research insights into tools and processes that improve teaching and learning in real world classrooms.

[8] Complementing this he developed a theoretical framework, Teaching for Robust Understanding (TRU),[9] a model of classrooms in which productive learning is likely to occur.

This identifies five key dimensions: the Mathematics; Cognitive demand; Access; Agency, authority and identity; Formative assessment.
