Despite the last 40 years of research showing that computer-aided diagramming tools improve student learning, very little research reveals the cognitive processes that explain why and how diagramming tools and specific features of the tools affect learning. This study developed a tool that graduate students used to diagram and analyze arguments as…

This study examined some of the methodological approaches used by students to construct causal maps in order to determine which approaches help students understand the underlying causes and causal mechanisms in a complex system. This study tested the relationship between causal understanding (ratio of root causes correctly/incorrectly identified,…

The purpose of this study was to examine the effects of diagrams and time-compressed instruction on learning and learners' perceptions of cognitive load. The following design factors, visuals (visuals and non-visuals) and time-compressed instruction (0%-normal paced, 25, and 50%) were presented to 216 university students to analyze learning in a…

This study investigated the effectiveness of three different levels of enhancement strategies utilized to facilitate students' learning from static and animated visualization when taking the time-on-task into consideration. Participants were randomly assigned to six treatment groups, and then took four criterion measures. The time-on-task was…

A study of 38 fifth-grade students investigated the effectiveness of two interactive multimedia instructional spelling programs, one offering behaviorist-visual learning options and the other offering cognitivist-phonological learning options. Both groups showed increased spelling ability, though neither program outperformed the other, suggesting…
