Objectives serve several important functions in instructional design. They provide a framework for evaluating student learning, convey the instructional intent, and provide targets for assessments. Objectives should be written to describe what learners will do to demonstrate their understanding. There are three main categories of objectives: cognitive, psychomotor, and affective. Cognitive objectives focus on knowledge and intellectual skills, psychomotor objectives involve physical skills, and affective objectives concern attitudes and values. Objectives help guide instruction and assessment and should be written using action verbs to specify observable and measurable outcomes for learners.
