Understanding ongoing chemical processes in the laboratory requires constant shifting between different representational levels--the macroscopic, submicroscopic, and symbolic levels--and analysis of the various mechanistic features of each of these levels. Thus, the ability to explain observations of chemical phenomena with regard to their…

Earth science concepts can be challenging for children to grasp due to their abstract nature. This study explores the potential of 3D computer animation as an engaging and effective medium to communicate various earth science processes to young learners. By creating age-appropriate, scientifically accurate visualizations of geological features and…

We developed a Quantum Mechanics Conceptual Understanding Survey (QMCUS) in this study. The survey was conducted using a quantitative methodology. A multiple-choice survey of 35 questions was administered to 338 undergraduate students. Three experienced quantum mechanics instructors examined the validity of the survey. The reliability of our…
