Gagne, Briggs and Wager (1988) stated that as “scientists, investigators are basically interested in explaining how learning takes place. In other words, their interest is in relating both the internal and external parts of a learning situation to the process of behavior change called learning" (p. 6) The behavior changes are linked to internal processes in which learning is conceived as information processing, When the internal processes formation processing of information processing are taken into account as leading to behavior change, then instruction becomes” a deliberately arranged set of external events designed to support internal learning processes" (p. 11), which leads to the desired behavior.
