Objective-based instruction focuses on defining clear learning objectives and using them to guide curriculum planning, instructional design, and student evaluation. The key aspects of this approach are: (1) defining objectives/outcomes, (2) designing learning experiences to help students achieve the objectives, and (3) evaluating student performance on the objectives. Learning experiences should be objective-based, learner-oriented, rich in variety, suitable to students' abilities, and practical enough to implement and evaluate. This approach contrasts with traditional education which focuses more on available resources than on empirically measuring students' attainment of defined objectives.
