- Abstract
In two studies, students' difficulties in using multiple external representations were effectively addressed. In a first explorative study (N = 16), we investigated the allocation of visual attention (as assessed by gaze data) on external representations, its relation to learning and learners' beliefs on the representations' functions. Results confirmed that students were not aware of the functions. In a subsequent experiment (N = 30), we analysed effects of informing students about the function of diagrams in worked examples on learning, mediating effects of visual attention and moderating effects of prior knowledge. The instruction had strong effects on learning, which were partially mediated by visual attention. Prior knowledge moderated both, the effects of the instruction on visual attention and of visual attention on learning. Implications for research into multiple representations and instructional design are discussed. Copyright © 2008 John Wiley & Sons, Ltd.
