1.2: Message Design

“Message design involves planning for the manipulation of the physical form of the
message” (Seels & Richey, 1994, p. 31). Message design is embedded within learning
theories (cognitive, psychomotor, behavioral, perceptual, affective, constructivist) in the
application of known principles of attention, perception, and retention which are intended
to communicate with the learner. This sub-domain is specific to both the medium selected
and the learning task.
