The document defines higher order thinking skills (HOTS) as skills based on Bloom's Taxonomy that involve more cognitive processing than lower order thinking skills (LOTS). HOTS include skills like analyzing, evaluating, and creating, while LOTS involve remembering, understanding, and applying. The focus of HOTS is on problem solving, critical thinking, and generating new ideas rather than drill and repetition. HOTS are more difficult to learn but provide more generalized benefits and ability to solve novel problems. Bloom's Taxonomy categorizes different levels of thinking from lower to higher order. HOTS are needed to progress, discover new fields, and solve complex problems facing the world.
