The Gagné Instructional Model outlines 9 steps to effective instructional design: 1) gaining attention, 2) informing learners of objectives, 3) stimulating recall of prior knowledge, 4) presenting the material, 5) providing guidance for learning, 6) eliciting performance, 7) providing feedback, 8) assessing performance, and 9) enhancing retention and transfer. The model correlates these instructional events with cognitive learning processes and considers different levels of learning.
