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)

Describes the design of a learning environment, called the Climate Visualizer, intended to facilitate scientific sense-making in high school classrooms by providing students the ability to craft, inspect, and annotate scientific visualizations. Discusses how visualizations can promote creation of scientific theories, especially in conjunction with…
