Hess Cognitive Rigor MatrixWhat is it?
The Hess Cognitive Rigor Matrix (CRM) is a
model that superimposed Bloom's Taxonomy
with Norman Webb's Depth-of-Knowledge
levels. The Hess CRM assists teachers in
applying what cognitive rigor might look like in
the classroom and guides test developers in
designing test items and performance tasks.
Content-specific descriptors in each of the Hess
CRMs are used to categorize and plan for
various levels of abstraction – meaning an
analysis of the mental processing required of
assessment questions and learning tasks.
