Who developed the 9 stages of learning?

The correct answer is Gagne, who developed the nine levels or stages of learning known as the "Conditions of Learning." Gagne's framework emphasizes that effective learning is a structured process and identifies different types of learning outcomes. The nine stages include gaining attention, informing the learner of the objective, stimulating recall of prior learning, presenting the stimulus material, providing learning guidance, eliciting performance (practice), providing feedback, assessing performance, and enhancing retention and transfer to the job. This model is designed to guide educators in facilitating learning more effectively by considering the mental processes involved and ensuring that all necessary conditions for learning are met. It highlights the significance of a systematic approach to instruction that can lead to more successful learning outcomes for students.
