This document discusses instructional objectives and different frameworks for writing them. It begins by explaining that teachers must be guided by instructional objectives to start teaching. It then describes Mager's format, which suggests objectives must be observable and measurable. It provides examples of precise versus imprecise verbs to use. The document also discusses Bloom's Taxonomy, which classifies objectives into cognitive, psychomotor, and affective domains to help systematically write objectives at different levels of complexity. Criticisms of Bloom's Taxonomy are noted at the end.
