Benjamin Bloom created a taxonomy of measurable verbs to help us describe and classify observable
knowledge, skills, attitudes, behaviors, and abilities. The theory is based upon the idea that there are levels of observable actions that indicate something is happening in the brain (cognitive activity.) By creating learning objectives using measurable verbs, you indicate explicitly what the student must do in order to demonstrate learning. (utica.edu)





Benjamin Samuel Bloom (February 21, 1913 – September 13, 1999) was an American educational psychologist who made contributions to the classification of educational objectives and to the theory of mastery learning. (wikipedia)

There are six levels of cognitive learning according to the revised version of Bloom’s Taxonomy. Each level is conceptually different. The six levels are remembering, understanding, applying, analyzing, evaluating, and creating.






1. Remember 
Definition: retrieve, recall, or recognize relevant knowledge from long-term memory
2. Understand
Definition: demonstrate comprehension through one or more forms of explanation
3. Apply
Definition: use information or skill in a new situation
4. Analyze
Definition: break material into its constituent parts and determine how the parts relate to one another and/or to an overall structure or purpose
5. Evaluate
Definition: make judgments based on criteria and standards
6. Create
Definitions: put elements together to form a new coherent or functional whole; reorganizing elements into a new pattern or structure
