The Split-Attention Principle in Multimedia Learning
Year: 2005
Type: book-chapter
Abstract: The split-attention principle states that when designing instruction, including multimedia instruction, it is important to avoid formats that require learners to split their attention between, and mentally integrate, multiple sources of information. Instead, materials should be formatted so that disparate sources of information are physically and temporally integrated thus obviating the need for learners to engage in mental integration. By eliminating the need to mentally integrate multiple sources of information, extraneous working memory load is reduced, freeing resources for learning. This chapter provides the theoretical rationale, based on cognitive load theory, for the split-attention principle, describes the major experiments that establish the validity of the principle, and indicates the instructional design implications when dealing with multimedia materials. Definition of Split-Attention Instructional split-attention occurs when learners are required to split their attention between and mentally integrate several sources of physically or temporally disparate information, where each source of information is essential for understanding the material. Cognitive load is increased by the need to mentally integrate the multiple sources of information. This increase in extraneous cognitive load (see chapter 2) is likely to have a negative impact on learning compared to conditions where the information has been restructured to eliminate the need to split attention. Restructuring occurs by physically or temporally integrating disparate sources of information to eliminate the need for mental integration. The split-attention effect occurs when learners studying integrated information outperform learners studying the same information presented in split-attention format. The split-attention principle flows from the split-attention effect.
