Computer-based learning environments (CBLEs) have emerged as powerful tools to support K-12 science learning. The Gas Laws simulation, an interactive, online CBLE, has been empirically demonstrated to support high-school students' understanding of particle theory, generally. However, a sub-analysis of existing data suggested certain embedded…

Virtual worlds are well-suited for building virtual laboratories for educational purposes to complement hands-on physical laboratories. However, educators may face technical challenges because developing virtual worlds requires skills in programming and 3D design. Current virtual world building tools are developed for users who have programming…

Color is a complex and rich perceptual phenomenon that relates physical properties of light to certain perceptual qualia associated with vision. Hering's opponent color theory, widely regarded as capturing the most fundamental aspects of color phenomenology, suggests that certain unique hues are mutually exclusive as components of a single color.…
