1
A Cognitive Theory of Multimedia Learning EDIT 610 – Multimedia Authoring
2
Multimedia Messages “Multimedia messages that are designed in light of how the human mind works are more likely to lead to meaningful learning than those that are not.” (2003, Mayer, p.41)
3
A Cognitive Theory of Multimedia Learning “A cognitive theory of multimedia learning assumes that the human information processing system includes dual channels for visual/pictorial and auditory/verbal processing, that each channel has limited capacity for processing and that active learning entails carrying out a coordinated set of cognitive processes during learning.” (2003, Mayer, p.41)
4
Five Steps in Multimedia Learning Selecting relevant words from presented or narrated text Selecting relevant images from the presented illustrations Organizing the selected words into a coherent verbal presentation Organizing selected images into a coherent visual presentation Integrating the visual and verbal representations and prior knowledge (2003, Mayer, p.41)
5
Three Criteria for Learner-Centered Design Intelligibility – the principles are derived from cognitive theory of multimedia learning Plausibility – the principles are consistent with empirical research on multimedia learning Applicability – the principles can be applied to new multimedia learning situations (2003, Mayer)
6
Three Assumptions about Cognitive Learning Theory Dual Channels Limited Capacity Active Processing (2003, Mayer)
7
Three Assumptions about Cognitive Learning Theory Dual Channels Humans possess separate channels for processing visual and auditory information (2003, Mayer)
8
Three Assumptions about Cognitive Learning Theory Limited Capacity Humans are limited in the amount of information that they can process in each channel at one time. (2003, Mayer)
9
Three Assumptions about Cognitive Learning Theory Active Processing Humans engage in active learning by attending to relevant incoming information, organizing selected information into coherent mental representations, and integrating mental representations with other knowledge. (2003, Mayer)
10
Dual-Channel Assumption “The dual-channel assumption is that humans possess separate information processing channels for visually represented material and auditorily represented material.” (Mayer, 2003, p.46)
11
Limited-Capacity Assumption “… human are limited in the amount of information that can be processed in each channel at one time.”
12
Limited-Capacity Assumption “Although there are individual differences, average memory span is fairly small – approximately five to seven chunks.”
13
Active Cognitive Processes “… humans actively engage in cognitive processing to construct a coherent mental representation of their experience.” Paying attention Organizing incoming information Integrating incoming information with other information
14
Knowledge Construction Process structures – cause & effect chains Comparison structures – comparing elements Generalization structures – main idea & subordinate skills Enumeration structures – lists of items Classification structures – hierarchies
15
Multimedia Design Implications Presented materials should have a coherent structure Messages should provide guidance on how to build appropriate structures
16
Five Steps for Multimedia Design Select relevant words Select relevant images Organize selected words Organize selected images Integrate word-based and picture- based representations
