Dounas-Frazer, Dimitri R.; Ríos, Laura; Pollard, Benjamin; Stanley, Jacob T.; Lewandowski, H. J. – Physical Review Physics Education Research, 2018
The ability to develop, use, and refine models of experimental systems is a nationally recognized learning outcome for undergraduate physics lab courses. However, no assessments of students' model-based reasoning exist for upper-division labs. This study is the first step toward development of modeling assessments for optics and electronics labs.…
