SIMS-Simulations & Modeling in Science: The science education community is at a critical point with regard to the development of curricula that use visualization tools. Although these tools have not seen widespread use, they possess much potential for improving learning. Such tools provide a unique benefit in that they can make explicit information embedded in traditional science representations and provide a visual representation of imperceptible objects. With such tools, students learn science by viewing simulations side-by-side with graphical outputs and diagrams. This is in stark contrast to traditional lecture formats that almost exclusively rely on verbal explanations of concepts. In the SIMS project, we implement computer-based learning environments for teaching chemistry. To that end, we develop and assess Connected Chemistry simulations, programmed in the NetLogo modeling environment to support student visualization of molecular events.
VDR: Visualization & Diagrammatic Reasoning for Problem Solving: Visualization is presumed critical for student success in science, but relatively little evidence is known about its form and function for genuine learning and problem solving. Rather, the bulk of evidence for visualization in science has been derived from correlations between measures of visuo-spatial ability and science achievement. In contrast, several studies have shown how science experts employ visualization on genuine tasks. The VDR project explores new theoretical frameworks regarding the role of visualization and diagrammatic reasoning at multiple levels of science learning. Using these frameworks, the project aims to inform new instructional approaches for high school and college chemistry. The project employs mixed-methods using measures of individual differences in visuo-spatial ability, reaction time measures, concurrent verbal protocols, and gestural analysis.
