Impact of Multimedia Presentation on Knowledge Acquisition for Complex Training

In this study we examined principles of multimedia training design within a complex task environment. We anticipated a differential effect for multimedia instructional format (redundant or non-redundant verbal information) on knowledge acquisition. Knowledge acquisition was assessed with increasingly more complex tasks, ranging from simple concept recognition assessment to transfer tasks tapping integrative knowledge. Our results show a significant benefit for redundant instruction on more complex transfer tasks. The discussion centers on the generalizability of multimedia design principles to computer-based training for complex systems
