This study examines the response patterns of 288 Spanish-English dual language learners on a standardized test of receptive Spanish vocabulary. Investigators analyzed responses to 54 items on the "Test de Vocabulario en Imagenes" (TVIP) [Dunn, L. M., D. E. Lugo, E. R. Padilla, and L. M. Dunn. 1986. "Test de Vocabulario en Imganes…

Erbeli, Florina; He, Kai; Cheek, Connor; Rice, Marianne; Qian, Xiaoning – Scientific Studies of Reading, 2023
Purpose: Researchers have developed a constellation model of decodingrelated reading disabilities (RD) to improve the RD risk determination. The model's hallmark is its inclusion of various RD indicators to determine RD risk. Classification methods such as logistic regression (LR) might be one way to determine RD risk within the constellation…

Purpose: This study aimed to examine the effect of an intensive vocabulary intervention embedded in e-books on the vocabulary skills of young Spanish-English speaking English learners (ELs) from low-socioeconomic status backgrounds. Method: Children (N = 288) in kindergarten and 1st grade were randomly assigned to treatment and read-only…

Purpose: This study aimed to examine the effect of an intensive vocabulary intervention embedded in e-books on the vocabulary skills of young Spanish-English speaking English Learners (ELs) from low SES backgrounds. Methods: Children (288) in kindergarten and first grade were randomly assigned to treatment and read-only conditions. All children…

Wood, Carla; Hoge, Rachel – International Journal of Bilingual Education and Bilingualism, 2019
Purpose: This study aimed to describe change in dual language learners' (DLLs) morphosyntactic skills from kindergarten to first grade based on a sentence repetition task in English and Spanish. Methods: The sample included Spanish-English speaking children (n = 25). Investigators employed a repeated measures analysis of variance with one…

Schatschneider, Christopher; Wagner, Richard K.; Hart, Sara A.; Tighe, Elizabeth L. – Scientific Studies of Reading, 2016
The present study employed data simulation techniques to investigate the 1-year stability of alternative classification schemes for identifying children with reading disabilities. Classification schemes investigated include low performance, unexpected low performance, dual-discrepancy, and a rudimentary form of constellation model of reading…

Erbeli, Florina; Hart, Sara A.; Wagner, Richard K.; Taylor, Jeanette – Scientific Studies of Reading, 2018
A fairly recent definition of reading disability (RD) is that in the form of a hybrid model. The model views RD as a latent construct that is manifested through various observable unexpected impairments in reading-related skills and through inadequate response to intervention. The current report evaluated this new conceptualization of RD from an…

Foorman, Barbara R.; Petscher, Yaacov; Stanley, Christopher; Truckenmiller, Adrea – Journal of Research on Educational Effectiveness, 2017
The objective of this study was to determine the latent profiles of reading and language skills that characterized 7,752 students in kindergarten through tenth grade and to relate the profiles to norm-referenced reading outcomes. Reading and language skills were assessed with a computer-adaptive assessment administered in the middle of the year…

This study investigated the psychometrics of the "Diagnostic Evaluation of Language Variation-Screening Test" (DELV-S) test using confirmatory factor analysis, item response theory, and differential item functioning (DIF). Responses from 1,764 students in kindergarten through second grade were used in the study, with results indicating…
