Bloom's Taxonomy

In 1956, Benjamin Bloom with collaborators published a framework for categorizing educational goals: Taxonomy of Educational Objectives. Bloom’s Taxonomy has been the framework applied by generations of K-12 teachers and college instructors in their teaching. The framework elaborated by Bloom and his collaborators consisted of six major categories: Knowledge, Comprehension, Application, Analysis, Synthesis and Evaluation. The categories after Knowledge were presented as “skills and abilities,” with the understanding that knowledge was the necessary precondition for putting these skills and abilities into practice.

While each category contained subcategories, all lying along a continuum from simple to complex and concrete to abstract, the taxonomy is popularly remembered according to the six main categories.[1]

The committee identified three domains of educational activities or learning (Bloom, et al. 1956):
