Higher–order thinking, known as higher order thinking skills (HOTS), is a concept of education reform based on learning taxonomies (such as Bloom’s Taxonomy). The idea is that some types of learning require more cognitive processing than others, but also have more generalized benefits. – Wikipedia
In 1956, Benjamin Bloom with collaborators Max Englehart, Edward Furst, Walter Hill, and David Krathwohl published a framework for categorizing educational goals: Taxonomy of Educational Objectives. Familiarly known as Bloom’s Taxonomy, this framework has been applied by generations of K-12 teachers and college instructors in their teaching.
