This document discusses higher order thinking skills (HOTS) and Bloom's Taxonomy of learning. It defines HOTS as skills involving critical, logical, reflective thinking that are activated when individuals encounter unfamiliar problems. Bloom's Taxonomy categorizes different levels of thinking from basic recall/remembering to higher order skills like analysis, evaluation, and creation. The document also discusses the difference between lower order skills like memorization versus higher order skills like critical thinking. It emphasizes the importance of developing students' HOTS through teaching strategies that go beyond basic factual recall.
