Answer: Benjamin Bloom.
Step-by-step explanation:
Benjamin Bloom, along with the collaboration of Walter Hill, Max Englehart, Edward Furst, and David Krathwohl, wrote Taxonomy of Educational Objectives (1956), mostly known as Bloom’s Taxonomy. It was a framework for classifying instructional goals, that has been used in K-12 and college since then.
It included six main categories (Knowledge, Comprehension, Application, Analysis, Synthesis, and Evaluation).
