Wang, Ting; Li, Min; Thummaphan, Phonraphee; Ruiz-Primo, Maria Araceli – International Journal of Testing, 2017
Contextualized items have been widely used in science testing. Despite common use of item contexts, how the influence of a chosen context on the reliability and validity of the score inferences remains unclear. We focused on sequential cues of contextual information, referring to the order of events or descriptions presented in item contexts. We…
