Robert Gagne developed nine events of instruction based on his theory of conditions of learning. The nine events are gaining attention, informing learners of objectives, stimulating recall of prior learning, presenting the stimulus, providing guidance, eliciting performance, providing feedback, assessing performance, and enhancing retention and transfer. When these events occur in instruction, they support various internal learning processes that lead to different learning outcomes. The events are not prescriptive but must be deliberately designed for each learning objective.
