Purpose: This study investigated the reading profiles of middle school Spanish-speaking emergent bilinguals (EBs) with significantly below grade level reading comprehension and whether these profiles varied in their reading comprehension performance over time. Method: Latent profile analyses were used to classify Grade 6 and 7 Hispanic EBs (n =…

The technical adequacy of CBM maze-scores as indicators of reading level and growth for seventh-grade secondary-school students was examined. Participants were 452 Dutch students who completed weekly maze measures over a period of 23 weeks. Criterion measures were school level, dyslexia status, scores and growth on a standardized reading test.…

The authors investigated the mediating effects of general academic and science-specific vocabulary on science reading comprehension among English learners (ELs) of varied proficiency. The sample included 169 regular education Grade 7 students (86 current ELs; 83 former ELs) enrolled in 1 urban school in Pacific Northwest region of the United…

Due to budget shortfalls, teacher furloughs were imposed in 2009 in Hawaii Public Schools. The furloughs resulted in a 2009-2010 school year of 167 days as opposed to the regular school year of 180 days. The purpose of this causal-comparative study with a pretest-posttest design was to examine the found effects of those furloughs on academic…

Discrimination has traditionally been parameterized for items but not other empirical factors. Consequently, if person factors affect discrimination they cause misfit. However, by explicitly formulating the relationship between discrimination and the unit of a metric, it is possible to parameterize discrimination for person groups. This article…

Over the past decade, educational policy trends have shifted to a focus on examining students' growth from kindergarten through twelfth grade (K-12). One way states can track students' growth is with a vertical scale. Presently, every state that uses a vertical scale bases the scale on a unidimensional IRT model. These models make a…

Interest in Student Growth Modeling (SGM) and Value Added Modeling (VAM) arises from educators concerned with measuring the effectiveness of teaching and other school activities through changes in student performance as a companion and perhaps even an alternative to status. Several formal statistical models have been proposed for year-to-year…

The Texas Assessment of Academic Skills (TAAS) test was the major source of data for the Texas educational accountability system from 1994 through 2002. Contrary to critics who claim that TAAS data are invalid and unreliable measures of student performance, structural equation analyses of TAAS reading data based on the 1994 Texas third grade…

Most growth models implicitly assume that test scores have been vertically scaled. What may not be widely appreciated are the different choices that must be made when creating a vertical score scale. In this paper empirical patterns of growth in student achievement are compared as a function of different approaches to creating a vertical scale.…

Because parameter estimates from different calibration runs under the IRT model are linearly related, a linear equation can convert IRT parameter estimates onto another scale metric without changing the probability of a correct response (Kolen & Brennan, 1995, 2004). This study was designed to explore a new approach to finding a linear…

All students from grades 3 through 8 were tested in the fall, winter, and spring of 2009 on passage reading fluency (PRF) measures from easyCBM [R]. Student characteristics were analyzed for influence on reading growth. The results showed the negative effects from being a male or a student of color, coming from an economically disadvantaged…
