Karte 341.1 Zitierfähigcognitive load - dual channel, limited capacity, active processing2014-12-05




We begin with three assumptions about how the human mind works based on research in cognitive science—the dual channel assumption, the limited capacity assumption, and the active processing assumption. (...) First, the human information-processing system consists of two separate channels—an auditory/verbal channel for processing auditory input and verbal representations and a visual/pictorial channel for processing visual input and pictorial representations. The dual-channel assumption is a central feature of Paivio’s (1986) dual-coding theory and Baddeley’s (1998) theory of working memory, although all theorists do not characterize the subsystems exactly the same way (Mayer, 2001). Second, each channel in the human information-processing system has limited capacity—only a limited amount of cognitive processing can take place in the verbal channel at any one time, and only a limited amount of cognitive processing can take place in the visual channel at any one time. This is the central assumption of Chandler and Sweller’s (1991; Sweller, 1999) cognitive load theory and Baddeley’s (1998) working memory theory. Third, meaningful learning requires a substantial amount of cognitive processing to take place in the verbal and visual channels. This is the central assumption of Wittrock’s (1989) generative-learning theory and Mayer’s (1999, 2002) selecting–organizing–integrating theory of active learning. These processes include paying attention to the presented material, mentally organizing the presented material into a coherent structure, and integrating the presented material with existing knowledge.
