Robert M. Gagné

Robert Mills Gagné (August 21, 1916 – April 28, 2002) was an American educational psychologist best known for his ''Conditions of Learning''. He instructed during World War II when he worked with the Army Air Corps training pilots. He went on to develop a series of studies and works that simplified and explained what he and others believed to be good instruction. Gagné was also involved in applying concepts of instructional theory to the design of computer-based training and multimedia-based learning.

His work is sometimes summarized as the Gagné assumption: that different types of learning exist, and that different instructional conditions are most likely to bring about these different types of learning. Provided by Wikipedia
