Gagne's Nine Events of Instruction

Robert Mills Gagne (1916-2002) was an American educator, experimental psychologist, and theorist, whose research led to the development of learning theories on instructional design and effective teaching practice. While serving as the Director of the U.S. Air Force’s Perceptual and Motor Skills Laboratory (1949-58), Gagne conducted a series of studies that culminated into his learning theory: Conditions of Learning. Out of this theory, Gagne formulated a model of direct instruction entitled the “Nine Events of Instruction.”
