Leahy, Wayne; Sweller, John – Instructional Science: An International Journal of the Learning Sciences, 2016
Based on cognitive load theory and the "transient information effect," this paper investigated the "modality effect" while interpreting a contour map. The length and complexity of auditory and visual text instructions were manipulated. Experiment 1 indicated that longer audio text information within a presentation was inferior…

Wong, Anna; Leahy, Wayne; Marcus, Nadine; Sweller, John – Learning and Instruction, 2012
When using modern educational technology, some forms of instruction are inherently transient in that previous information usually disappears to be replaced by current information. Instructional animations and spoken text provide examples. The effects of transience due to the use of animation-based instructions (Experiment 1) and spoken information…

Leslie, Kimberley Crompton; Low, Renae; Jin, Putai; Sweller, John – Educational Technology Research and Development, 2012
Two experiments using the science topics of Magnetism and Light were conducted with younger learners (Year 5) who had no prior knowledge of the topics, and older learners (Year 6) who had studied the topics previously. Half of the learners were presented the information in auditory form only while the other half were presented the auditory…

Tindall-Ford, Sharon; Sweller, John – Instructional Science: An International Journal of Learning and Cognition, 2006
Under some conditions, learning is improved by using a dual mode presentation involving for example, visual diagrams and auditory, rather than written text (modality effect). Under other conditions, learning is improved by asking learners to imagine rather than study instructional material (imagination effect). Both effects have been explained…
