Categorical perception (CP) effects manifest as faster or more accurate discrimination between objects that come from different categories compared with objects that come from the same category, controlling for the physical differences between the objects. The most popular explanations of CP effects have relied on perceptual warping causing…

America's diverse higher education landscape includes more than 700 four-year nonprofit colleges and universities that focus on baccalaureate education. These private nondoctoral (PND) institutions are located in almost every state and collectively enroll about 1.6 million students and award nearly 150,000 degrees annually, with the majority of…

The paper reports a research study aimed at investigating the appeal and pedagogical efficacy of animated teaching avatars. Specifically, the goal of the study was to determine whether animated characters could be effective and engaging teachers in the context of undergraduate surveying mathematics. The study included two forms of evaluation:…

Many benefits have been claimed for visualizations, a general assumption being that learning is facilitated. However, several researchers argue that little is known about the cognitive value of graphical representations, be they schematic visualizations, such as diagrams or more realistic, such as virtual reality. The study reported in the paper…

We studied the use of online molecular dynamics simulations (MD) to enhance student abilities to understand the atomic processes governing plastic deformation in materials. The target population included a second-year undergraduate engineering course in the School of Materials Engineering at Purdue University. The objectives of the study were to…

Reports on a program developed in Indiana public schools to hold software evaluation workshops that would compare teacher and student evaluations of the same software. The evaluation process is discussed; tutorials, drill and practice programs, simulations, and games are examined; and tests for correlation are described. (21 references) (LRW)
