Bloom's Hierarchy “Although it received little attention when first published, Bloom's Taxonomy has since been translated into 22 languages and is one of the most widely applied and most often cited references in education.” (Anderson & Sosniak, 1994, preface), (Houghton, 2004), (Krathwohl, 2002), (oz-TeacherNet, 2001)

Benjamin Bloom Professor, University of Chicago At the 1948 Convention of the American Psychological Association, Bloom decided to lead a group of educators in “the ambitious task of classifying educational goals and objectives.” The group intended to analyze behaviors of thought that seemed important to the learning process. In 1956, eight years after the group first began, “Bloom’s Taxonomy” was completed and a handbook was published.

Traditional Bloom's Taxonomy One-dimensional model of learning As instructional practices began to shift towards performance assessments and performance-based instruction, researchers revised Bloom’s Taxonomy. More detailed objectives were necessary, and the one-dimensional model wasn’t sufficient for guiding the writing of these objectives. Performance-based instruction involves metacognitive skills, such as self-evaluation.

Bloom's Taxonomy Revision Read the standards in your curriculum area. Using the two-dimensional model, place each standard in the appropriate block based upon the type of knowledge and cognition needed to master the standard. Discuss one instructional method that could be used to allow students to practice and illustrate mastery of one objective at the appropriate level of cognition.
