The document discusses Benjamin Bloom's taxonomy of educational objectives, which classifies objectives into three domains: cognitive, affective, and psychomotor. The cognitive domain involves knowledge, comprehension, application, analysis, synthesis, and evaluation. The affective domain focuses on changes in interest, attitudes, and values. The psychomotor domain deals with physical skills and movement. Each domain contains objectives classified by specific action verbs. The objectives are meant to clearly define the skills, knowledge, and attitudes students should gain from instruction.
