As chemistry education, and science education more broadly, have shifted to emphasize realistic scientific practices as an important component of education, a number of researchers have used the Students' Understanding of Models in Science (SUMS) instrument to assess students' knowledge about scientific models and modelling. SUMS has also been…

Rodriguez, Jon-Marc G.; Stricker, Avery R.; Becker, Nicole M. – Chemistry Education Research and Practice, 2020
Explanations of phenomena in chemistry are grounded in discussions of particulate-level behavior, but there are limitations to focusing on single particles, or as an extension, viewing a group of particles as displaying uniform behavior. More sophisticated models of physical processes evoke considerations related to the dynamic nature of bulk…

Becker, Nicole M.; Rupp, Charlie A.; Brandriet, Alexandra – Chemistry Education Research and Practice, 2017
Models related to the topic of chemical kinetics are critical for predicting and explaining chemical reactivity. Here we present a qualitative study of 15 general chemistry students' reasoning about a method of initial rates task. We asked students to discuss their understanding of the terms rate law and initial rate, and then analyze rate and…
