This paper outlines four principles for preparing multimedia instructional sequences and, where necessary, the experimental methods for applying the principles successfully. Covered first are the criteria for good terminology for unfamiliar objects, actions, and situations, with methods for deriving such terminology. In the next section guidelines…

Although teachers may sequence instructions carefully, they are unable to respond to the complex unique experience of each individual learner.

Learning is problem solving; when individuals do not know how to deal…
