Bloom's Taxonomy is an educational framework that categorizes levels of cognition. It was created in 1956 to improve curriculum, assessments, and teaching. There are three domains: cognitive, affective, and psychomotor. The cognitive domain involves knowledge, comprehension, application, analysis, evaluation, and creation. Bloom's Taxonomy provides a structure for teachers to set clear learning objectives, develop assessments, and help students achieve higher levels of thinking. It is a useful tool for improving instructional practices.
