Purpose: We investigated four theoretically based latent variable models of word learning in young school-age children. Method: One hundred sixty-seven English-speaking second graders with typical development from three U.S. states participated. They completed five different tasks designed to assess children's creation, storage, retrieval, and…

This study examined the internal structure of the Classroom Assessment Scoring System (CLASS; K-3 version). The original CLASS K-3 model (Pianta, La Paro, & Hamre, 2008) and 5 alternative models were tested using confirmatory factor analysis with a sample of first- and second-grade classrooms (N = 141). Findings indicated that a slightly…

The factor structure of the Phonological Awareness Literacy Screening for Grades 1 through 3 (PALS 1-3), a widely used early literacy screener in the Commonwealth of Virginia, was investigated using a large sample of public-school second-grade students (n = 14,993). Three alternative factor models (i.e., a one-factor, two-correlated factors, and a…

The study's purpose was to develop and validate a scale for assessing interest in mathematics among elementary students as part of an identification protocol for gifted and talented programming. Lohman recommends assessment of interest as a critical element within the ideal approach to identification. Hidi and Renninger's Four-Phase Interest…

The Brigance Comprehensive Inventory of Basic Skills-II (CIBS-II) is the newest version of a long-standing instrument that is useful for identifying student achievement, identifying and monitoring academic strengths and weaknesses, obtaining data to support referrals, and reporting progress for individual educational plans. Since the CIBS-II is…

In both the school effectiveness and the educational administration literature, growing attention has been paid to the extent of principal leadership effects and the means by which they affect school performance. The main goal of this study is to estimate the effects of principal leadership on students' achievement growth in mathematics over a…

Background/Context: Little research has directly examined whether principal leadership can increase the degree to which teachers work together regularly in focused ways around content. Prior research has shown that reform efforts seeking to alter the process of teaching can be successful if teachers collaborate to build capacity and improve…

Previous research has provided evidence for the utility of the Minneapolis Kindergarten Assessment (MKA), which is a measure of early literacy and numeracy skills. The present research was undertaken to replicate previous factorial results and evaluate the relative strength of an alternative parameterization of the measurement model, the bifactor…

The purpose of this study was to examine the construct and predictive validity of a dynamic assessment (DA) of decoding learning. Students (N = 318) were assessed in the fall of first grade on an array of instruments that were given in hopes of forecasting responsiveness to reading instruction. These instruments included DA as well as…

The primary purpose of this study was to examine several key questions related to the neuropsychological contributors to early written language. First, can we develop an empirical measurement model that encompasses many of the neuropsychological components that have been deemed as important to the development of written language? Second, once…

What is the nature of learning to read Chinese across grade levels? This study tested 199 kindergartners, 172 second graders, and 165 fifth graders on 12 different tasks purportedly tapping constructs representing phonological awareness, morphological awareness, orthographic processing, and subcharacter processing. Confirmatory factor analyses…
