Bloom’s taxonomy

The original Bloom B. S. (1956). Taxonomy of Educational Objectives, Handbook I: The Cognitive Domain. New York: David McKay Co Inc.

The Performance Juxtaposition Site, a website about performance, learning, training and leadership has an overview of Bloom’s taxonomy of learning Domains: the three types of learning

Domains can be thought of as categories. Trainers often refer to these three categories as KSA (Knowledge, Skills, and Attitude). This taxonomy of learning behaviors can be thought of as “the goals of the learning process.” That is, after a learning episode, the learner should have acquired new skills, knowledge, and/or attitudes.

Lorin Anderson, a former student of Bloom, revisited the cognitive domain
