In this study, we test the prediction, derived from the Critical Period Hypothesis, that a native level in L2 grammar cannot be attained by learners who start acquiring a second language after childhood. We selected 43 very advanced late learners of Dutch (native speakers of German, French and Turkish) and compared their performance on a grammar…

The authors describe the preliminary development and validation of the Authenticity in Relationships Scale. An initial pool of 37 items addressing various elements of the proposed definition of "relationship authenticity" was administered to 2 independent samples of undergraduates (N = 487) who acknowledged being in a current romantic…

DETECT, the acronym for Dimensionality Evaluation To Enumerate Contributing Traits, is an innovative and relatively new nonparametric dimensionality assessment procedure used to identify mutually exclusive, dimensionally homogeneous clusters of items using a genetic algorithm ( Zhang & Stout, 1999). Because the clusters of items are mutually…

The aim of this study was to explore the claim that the hybrid nature of synchronic computer-mediated chat (SCMC) promotes the noticing of target language forms, which may, in turn, stimulate the process of second language actuation. When viewed in the context of interaction theory, the hybrid nature of SCMC makes online negotiation a potentially…

Although specific tests screen children in preschool programs for vision, hearing, and dental conditions, there are no published validated instruments to detect preschool-age children with asthma, one of the most common pediatric chronic conditions affecting children in economically disadvantaged communities of color. As part of an asthma…

This study investigates item parameter recovery, standard error estimates, and fit statistics yielded by the WINSTEPS program under the Rasch model and the rating scale model through Monte Carlo simulations. The independent variables were item response model, test length, and sample size. WINSTEPS yielded practically unbiased estimates for the…

Panelists in an operational standard-setting study were asked to share their thoughts in written form at important points in the process itself--before the meeting started, after training, after completing the 1st and 2nd sets of ratings, immediately following the discussion between Rounds 1 and 2, and so on. The item mapping method of Plake and…

This study examines the effect and validity of accommodations for limited English proficiency (LEP) students in the National Assessment of Educational Progress (NAEP) and the impact of language factors on the assessment and accommodation of these students. Results indicate that accommodations used in NAEP did not reduce the performance gap between…

The use of accommodations has been widely proposed as a means of including English language learners (ELLs) or limited English proficient (LEP) students in state and districtwide assessments. However, very little experimental research has been done on specific accommodations to determine whether these pose a threat to score comparability. This…

Having students express their understanding of difficult, new material in their own words is an effective method to deepen their comprehension and learning. Summary Street[R] is a computer tutor that offers a supportive context for students to practice this activity by means of summary writing, guiding them through successive cycles of revising…

Model-based equating was compared to empirical equating of an Armed Services Vocational Aptitude Battery (ASVAB) test form. The model-based equating was done using item pretest data to derive item response theory (IRT) item parameter estimates for those items that were retained in the final version of the test. The analysis of an ASVAB test form…

The purpose of this study was to investigate perceptions of the counseling needs of gifted children from the perspective of parents who sought help from a fee-based counseling center for gifted students. The counseling center provided assessment and educational and career guidance, as well as family social/emotional counseling, all of which were…

This article revisits the important issue raised by Peter Tymms where he challenges the official government reports of an impressive rise in standards in mathematics and English in primary schools in England since 1995, suggesting that the rise in scores, particularly since 2000, does not indicate rising standards. In order to substantiate its…

The present study investigated the effects of reducing the number of options per item on psychometric characteristics of a Japanese EFL university entrance examination. A four-option multiple-choice reading test used for entrance screening at a university in Japan was later converted to a three-option version by eliminating the least frequently…

In this technical report, the authors describe the development and piloting of reading comprehension measures as part of a comprehensive progress monitoring literacy assessment system developed in 2006 for use with students in Kindergarten through fifth grade. They begin with a brief overview of the two conceptual frameworks underlying the…
