How Bloom’s Taxonomy Came About
Discussions at the 1948 Convention of the American Psychological Association resulted in Benjamin Bloom leading a group of educators in an effort to classify educational goals and objectives. The goal was to come up with thinking behaviors that were important to the process of learning (Forehand, 2011).
Fast forward eight years and in 1956, the group produced a book explaining their new classification system of the cognitive domain—a hierarchy with six levels. The original group always thought of the taxonomy as a work in progress (Anderson & Krathwohl, 2001).
Many readers have also seen the Anderson & Krathwohl revised version from 2001. The key change in this version is, “in the more useful and comprehensive additions of how the taxonomy intersects and acts upon different types and levels of knowledge — factual, conceptual, procedural and metacognitive” (Wilson, 2016).
