A Brief History Of Bloom’s Taxonomy

Bloom’s Taxonomy taxonomy was proposed in 1956 by a cohort led Benjamin Bloom, an educational psychologist at the University of Chicago.

It was published as a kind of classification of learning outcomes and objectives that have, in the more than half-century since, been used for everything from framing digital tasks and evaluating apps to writing questions and assessments.

According Dr. Bloom himself, “The idea for this classification system was formed at an informal meeting of college examiners attending the 1948 American Psychological Association Convention in Boston. At this meeting, interest was expressed in a theoretical framework which could be used to facilitate communication among examiners. This group felt that such a framework could do much to promote the exchange of test materials and ideas about testing. In addition, it could be helpful in stimulating research on examining and on the relations between examining and education. After considerable discussion, there was agreement that such a theoretical framework might best be obtained through a system of classifying the goals of the educational process, since educational objectives provide the basis for building curricula and tests and represent the starting point for much of our educational research.”

This meeting became the first of a series of informal annual meetings of college examiners. Gathering at a different university each year and with some changes in membership, this group has considered the problems invo.lved in organizing a classification of educational objectives. The group has also considered a great many other problems of examining and of educational research. This is the first product of these meetings.

The taxonomy was updated in 2001. More on that soon.
