Multimedia Learning: The Promise of Multimedia Learning

Multimedia learning occurs when students build mental representations from words and pictures that are presented to them (e.g., printed text and illustrations or narration and animation). The promise of multimedia learning is that students can learn more deeply from well-designed multimedia messages consisting of words and pictures than from more traditional modes of communication involving words alone. This article explores a program of research aimed at determining (a) research-based principles for the design of multimedia explanations—which can be called methods, and (b) the extent to which methods are effective across different learning environments—which can be called media. A review of research on the design of multimedia explanations conducted in our lab at Santa Barbara shows (a) a multimedia effect—in which students learn more deeply from words and pictures than from words alone—in both book-based and computer-based environments, (b) a coherence effect—in which students learn more deeply when extraneous material is excluded rather than included—in both book-based and computer-based environments, (c) a spatial contiguity effect—in which students learn more deeply when printed words are placed near rather than far from corresponding pictures—in both book-based and computer-based environments, and (d) a personalization effect—in which students learn more deeply when words are presented in conversational rather than formal style—both in computer-based environments containing spoken words and those using printed words. Overall, our results provide four examples in which the same instructional design methods are effective across different media.  2003 Elsevier Science Ltd. All rights reserved.
