Two experiments are reported that investigated the relative effectiveness of a realistic dynamic visualization as opposed to a schematic visualization for learning about cell replication (mitosis). In Experiment 1, 37 university students watched either realistic or schematic visualizations. Students' subjective task demands ratings as well as…

The aim of this article is to investigate with high and low knowledge subjects in the scientific domain of the neuron, the way information should be presented and illustrated to promote the integration of new information. This fundamental process for learning was examined in two experiments using a primed recognition task. In the first study, the…

Hierarchical graphs represent relationships between objects (like computer file systems, family trees etc.). Graph nodes represent the objects and interconnecting lines represent the relationships. In two experiments we investigated what concepts are necessary for understanding hierarchical graphs, what misconceptions evolve when some of the…
