Overview
The Multimedia Principle is one of Mayer's 12 multimedia learning principles that foster generative processing in the cognitive theory of learning. The Multimedia Principle states that 'learners generally benefit from the inclusion of words with graphics rather than the use of either words or graphics alone(Mayer, n.d.).' By words, we mean printed text (words displayed on the screen that people read) or spoken text (words presented as speech that people listen to through earphones or speakers). By graphics, we mean static illustrations such as drawings, charts, graphs, maps, or photos, and dynamic graphics such as animation or video. We use the term multimedia representation to refer to any presentation that contains both words and graphics. The implication of the principle through graphic inclusion should be considered carefully with the content and audience.
Evidence
The multimedia principle does not apply equally to all learners. It works best for novices. (Mayer, n.d.) Here we define ‘novices’ as learners with low knowledge of the domain and ‘experts’ as learners with high knowledge of the domain. The supportive evidence is a series of three experiments involving lessons on brakes, pumps, and generators, Mayer andGallini (1990) reported that novices learned better from text and graphics (such as shown in Figure 4.8) than from words alone (such as shown in Figure 4.7). However, experts learned equally well from both conditions.
In the study, Ollerenshaw, Aidman, and Kidd (1997) presented text lessons on how pumps work to learners who had low or high knowledge of the domain. Low-knowledge learners benefited greatly when the animation was added to the text, whereas high-knowledge learners did not. These findings prompted Kalyuga and colleagues to propose the ‘expertise reversal effect’, which holds that instructional support that benefits low-knowledge learners may not benefit (or may even harm) high-knowledge learners. Overall, instructional designers should be aware of the level of prior knowledge of their target audiences in order to provide the necessary support, such as multimedia instruction, to low-knowledge learners.
