- Robert Marzano proposed a new taxonomy of educational objectives to address shortcomings of Bloom's Taxonomy. His model incorporates a wider range of factors that affect how students think.
- Marzano's taxonomy includes three systems - the Self System, Metacognitive System, and Cognitive System - as well as a Knowledge Domain. The Self System determines whether to engage in a new task. The Metacognitive System sets goals and monitors progress. The Cognitive System processes information using thinking strategies. The Knowledge Domain provides content.
- Together, these systems and domain describe the thinking process and how knowledge is retrieved, comprehended, analyzed, and utilized to drive higher-order thinking.
