Over the last 20 years, many methods have been proposed to use process data (e.g., response time) to detect changes in engagement during the test-taking process. However, many of these methods were developed and evaluated in highly similar testing contexts: 30 or more single-select multiple-choice items presented in a linear, fixed sequence in…

Lopez, Alexis A.; Guzman-Orth, Danielle; Zapata-Rivera, Diego; Forsyth, Carolyn M.; Luce, Christine – ETS Research Report Series, 2021
Substantial progress has been made toward applying technology enhanced conversation-based assessments (CBAs) to measure the English-language proficiency of English learners (ELs). CBAs are conversation-based systems that use conversations among computer-animated agents and a test taker. We expanded the design and capability of prior…

Lopez, Alexis A.; Tolentino, Florencia – ETS Research Report Series, 2020
In this study we investigated how English learners (ELs) interacted with "®" summative English language arts (ELA) and mathematics items, the embedded online tools, and accessibility features. We focused on how EL students navigated the assessment items; how they selected or constructed their responses; how they interacted with the…

Robin, Frédéric; Bejar, Isaac; Liang, Longjuan; Rijmen, Frank – ETS Research Report Series, 2016
Exploratory and confirmatory factor analyses of domestic data from the" GRE"® revised General Test, introduced in 2011, were conducted separately for the verbal (VBL) and quantitative (QNT) reasoning measures to evaluate the unidimensionality and local independence assumptions required by item response theory (IRT). Results based on data…

Ali, Usama S.; Chang, Hua-Hua – ETS Research Report Series, 2014
Adaptive testing is advantageous in that it provides more efficient ability estimates with fewer items than linear testing does. Item-driven adaptive pretesting may also offer similar advantages, and verification of such a hypothesis about item calibration was the main objective of this study. A suitability index (SI) was introduced to adaptively…

Morley, Mary; Bridgeman, Brent; Lawless, René – ETS Research Report Series, 2004
This study investigated the transfer of solution strategies between close variants of quantitative reasoning questions. Pre- and posttests were obtained from 406 college undergraduates, all of whom took the same posttest; pretests varied such that one group of participants saw close variants of one set of posttest items while other groups saw…
