Large scale international assessments depend on invariance of measurement across countries. An important consideration when observing cross-national differential item functioning (DIF) is whether the DIF actually reflects a source of bias, or might instead be a methodological artifact reflecting item response theory (IRT) model misspecification.…

Effectively evaluating the credibility and accuracy of multiple sources is critical for college readiness. We developed 24 source evaluation tasks spanning four predicted difficulty levels of a hypothesized learning progression (LP) and piloted these tasks to evaluate the utility of an LP-based approach to designing formative literacy assessments.…

The purpose of this study is to construct a digital culture test in light of the Item Response Theory and to investigate its psychometric properties. The study sample consisted of six hundred fifty (650) male and female students in the eighth grade from the Directorate of Education and Teaching of Salt District. To obtain the results, the…

This study examined the existence of latent classes in TIMSS 2015 data from three countries, Singapure, Turkey and South Africa, were analyzed using Mixture Item Response Theory (MixIRT) models (Rasch, 1PL, 2PL and 3PL) on 18 multiple-choice items in the science subtest. Based on the findings, it was concluded that the data obtained from TIMSS…

The so-called control-of-variables strategy (CVS) incorporates the important scientific reasoning skills of designing controlled experiments and interpreting experimental outcomes. As CVS is a prominent component of science standards appropriate assessment instruments are required to measure these scientific reasoning skills and to evaluate the…

Helping students develop a sound understanding of scientific concepts can be a major challenge. Lately, learning progressions have received increasing attention as a means to support students in developing understanding of core scientific concepts. At the center of a learning progression is a sequence of developmental levels reflecting an…

This paper describes one of the first efforts by the National Assessment of Educational Progress (NAEP) to improve measurement at the lower end of the distribution, including measurement for students with disabilities (SD) and English language learners (ELLs). One way to improve measurement at the lower end is to introduce one or more…

The least squares distance method (LSDM) was used in a cognitive diagnostic analysis of TIMSS (Trends in International Mathematics and Science Study) items administered to 4,498 8th-grade students from seven geographical regions of Turkey, extending analysis of attributes from content to process and skill attributes. Logit item positions were…

We expect that word knowledge accumulates gradually. This article draws on earlier approaches to assessing depth, but focuses on one dimension: richness of semantic knowledge. We present results from a study in which three distinct item types were developed at three levels of depth: knowledge of common usage patterns, knowledge of broad topical…

This article provides an overview of the development and validation of the Student Tool for Technology Literacy (ST[superscript 2]L). Developing valid and reliable objective performance measures for monitoring technology literacy is important to all organizations charged with equipping students with the technology skills needed to successfully…

This study compared performance of both English language learners (ELLs) and non-ELL students in Grades 4 and 8 under accommodated and nonaccommodated testing conditions. The accommodations used in this study included a computerized administration of a math test with a pop-up glossary, a customized English dictionary, extra testing time, and…

The purpose of this study was to develop general outcome measures (GOM) in mathematics so that teachers could focus their instruction on needed prerequisite skills. We describe in detail, the manner in which content-related evidence was established and then present a number of statistical analyses conducted to evaluate the technical adequacy of…

The purpose of this study was to develop and gather validity evidence for silent reading fluency passages. A number of passages were written following a traditional story grammar structure (character, setting, events) and placed on a computer for students to read silently. We describe in detail, the manner in which content-related evidence was…
