Learning with instructional animations may overstretch limited working memory resources due to intense processing demands associated with transient information. The authors investigated whether explicit instructional advice coupled with a task-specific learner control mechanism (such as a timeline scrollbar) could facilitate the successful…

The "interactivity principle" in multimedia learning states that giving learners control over pace and order of instructions decreases cognitive load and increases transfer performance. We tested this guideline by comparing a learner-paced instruction with a system-paced instruction. Time-on-task and interactive behavior were logged, and were also…

A "science of e-learning" involves the scientific investigation of how people learn in electronic learning environments. Three elements of a science of e-learning are: a) "evidence"--a base of replicated findings from rigorous and appropriate research studies; b) "theory"--a research-based theory of how people learn in electronic learning…
