What is The Dual Coding Theory

Chapter 17
Handbook of Research on Instructional Systems and Technology
The dual coding theory describes the role of sensory inputs in information processing. According to the dual coding theory, different forms of information such as verbal, visual, and auditory information are registered through different channels (Paivio, 1986). For example, the auditory information is registered through the auditory channel and the visual information is registered through the visual channel. The auditory and visual information then interact with each other within the working memory to form a mental representation of the external world (Mayer, 2001). Paivio (1986) argued that learners learn better when information is presented through multiple sensory channels, rather than one channel only. Studies (see Mayer, 1997; Mayer et al., 1991; Mayer et al., 2003) show that different presentation modes (i.e., words vs. pictures) and sensory modalities (i.e., audio vs. visual) may affect students’ learning differently.

Cognitive Functionality of Multimedia in Problem Solving

Abstract
Teaching problem solving can be a challenge to teachers. However, the challenge is oftentimes not due to a lack of skills on the part of learners but due to an inappropriate design of media through which the problem is presented. The findings of this study demonstrate that appropriately designed multimedia can improve learners’ problem solving skills because of the cognitive functions such media have in facilitating mental representation and information retrieval and maintenance, as well as reducing cognitive load during the problem solving process. Suggestions were made on how to apply interactive multimedia to teaching and learning.
