An extensive research literature in education and psychology demonstrates positive effects of perspective-taking on various forms of learning. Until recently, perspective-taking has been limited to the mental simulation of how someone with different beliefs, knowledge, physical location, etc., perceives an object or event. Over the last decade…

How can cognitive load in visual displays of computer simulations be optimized? Middle-school chemistry students (N = 257) learned with a simulation of the ideal gas law. Visual complexity was manipulated by separating the display of the simulations in two screens (low complexity) or presenting all information on one screen (high complexity). The…

Describes Wavemaker, a simulation environment developed to graphically reveal the behavior of periodic systems using a series of increasingly sophisticated visual tools. Results indicate that the software is helpful in connecting real to simulated systems. (Author/CCM)
