The Evolution of Bloom's Taxonomy

The Evolution of Bloom's Taxonomy


For over 60 years, Bloom's taxonomy has been used as an instructional design tool to create curriculum, activities, and assessments, with the goal to ensure that all orders of thinking are exercised in students' learning process, including their ability to search for information. 

The original taxonomy was a set of three hierarchical models that classified learning objectives into levels of complexity. It was created in 1956 by Benjamin Bloom with collaborators Max Englehart, Edward Furst, Walter Hill, and David Krathwohl and published in Taxonomy of Educational Objectives: The Classification of Educational Goals.

In 2001, a group of cognitive psychologists, curriculum theorists, instructional researchers, and testing and assessment specialists published a revision of Bloom’s Taxonomy with the title A Taxonomy for Teaching, Learning, and Assessment. This title draws attention away from the static notion of “educational objectives” (in Bloom’s original title) and points to a more dynamic concept of classification.

In this module, we will look at the evolution of Bloom's taxonomy and the contributions by other researchers and educators to make it relevant to changing education scenarios.
