Bloom’s taxonomy is a set of three hierarchical models used to classify educational learning objectives into levels of complexity and specificity. The models organize learning objectives into three different domains: Cognitive, Affective, and Sensory/Psychomotor. 

Bloom’s taxonomy was developed to promote higher forms of thinking in education, such as analyzing and evaluating concepts, processes, procedures, and principles, rather than simply memorizing facts. It is a framework for educational achievement in which each level depends on the one below, often drawn as a pyramid. The model is used in instructional design primarily for creating effective learning objectives.


The foundation and first level of the pyramid is remember. This level is dependent upon learners’ ability to memorize and recall key facts and concepts. For example, a learner may exhibit memory and retention by repeating information or memorizing key facts. One way to test learners’ ability to remember is to administer multiple-choice tests.

It is the first step of revised bloom taxonomy model The cognitive domain is focused on intellectual skills such as critical thinking, problem solving, and creating a knowledge base. It was the first domain created by the original group of Bloom’s researchers. The cognitive hierarchy spans from simple memorization designed to build the knowledge of learners, to creating something new based on previously-learned information. In this domain, learners are expected to progress linearly through the hierarchy, beginning at “remember” and ending at “create.”

  • Remember
    • Sample learning outcome: Remember the names and relationships of a cast of characters in a play.
    • Sample assessment/activity: A multiple-choice test designed to test the memory of learners.
    • Rationale: A multiple-choice test will allow educators to see whether students have effectively memorized the given material.
