ChemVLab+ : evaluating a virtual lab tutor for high school chemistry

Conceptual understanding in chemistry requires students to connect quantitative calculations, microscopic chemical processes (e.g., atoms and molecules), and macroscopic outcomes (e.g., concentrations, color, temperature). The ChemCollective Virtual Lab's interactive simulation environment fosters the mapping between these representations by providing students with a fully functional online chemistry lab with realistic chemicals, glassware, and...
