Multiple-choice/multiple-response (MCMR) items (i.e., multiple-choice questions for which there may be more than one correct response) can be a valuable tool for assessment. Like traditional multiple-choice/single-response questions, they are easy to grade; but MCMR items may provide more information about student reasoning by probing multiple facets of reasoning in a single problem context. Because MCMR items are infrequently used, best practices for their implementation are not established. In this paper, we describe the administration of MCMR items on an online, research-based assessment. We discuss possible differences in performance on MCMR items that may result from differences in administration method (in-person vs. online). This work is presented as a potential first step toward establishing best-practices for the administration of MCMR items on online assessments.
Research-based assessment instruments (RBAIs) are ubiquitous throughout both physics instruction and physics education research. The vast majority of analyses involving student responses to RBAI questions have focused on whether or not a student sele
Learning physics is a context dependent process. I consider a broader interdisciplinary problem of where differences in understanding and reasoning arise. I suggest the long run effects a multiple choice based learning system as well as society cultu
Item response theory (IRT) models for categorical response data are widely used in the analysis of educational data, computerized adaptive testing, and psychological surveys. However, most IRT models rely on both the assumption that categories are st
This experiment was conducted to study the effect of administration {gamma}-amino butyric acid (GABA) on physiology performance of broiler chicks. The following treatments were used: T1:control treatment, T2: the birds were administration 0.2ml 0.4%
We investigate students sense of ownership of multiweek final projects in an upper-division optics lab course. Using a multiple case study approach, we describe three student projects in detail. Within-case analyses focused on identifying key issues
