This research project is based on assumptions about cognitive load mediating instructional design effects in multimedia learning. The spatial contiguity of text and corresponding graphic (split-attention effect) as well as individual learner characteristics like prior knowledge (expertise reversal effect) have shown to influence multimedia learning. The Cognitive Load Theory (Sweller, Van Merrienboer & Paas, 1998) and the Cognitive Theory of Multimedia Learning (Mayer, 2003; 2005) offer different explanations on how cognitive load mediates both effects. The project investigates the cognitive load mechanism underlying the split-attention and expertise reversal effect by means of secondary task performance, subjective ratings scales and parameters of viewing behavior.
