Drawing upon the literature in computational modeling, multivariable reasoning, and causal attribution, this study aims at characterizing multivariable reasoning practices in computational modeling and revealing the nature of understanding about multivariable causality. We recruited two freshmen, two sophomores, two juniors, two seniors, four…

Researchers and practitioners have attempted to identify technologies that support students' scientific understanding, activities and support practices that facilitate students' inquiry processes, and methods to sustain technology-enhanced innovations in everyday science classrooms. The purpose of this paper is to examine the findings and…

Holding the premise that the development of expertise is a continuous process, this study concerns expert models and modeling processes associated with a modeling tool called Model-It. Five advanced Ph.D. students in environmental engineering and public health used Model-It to create and test models of water quality. Using "think aloud" technique…
