In response to a request for additional analyses, in particular reporting confidence intervals around the results, we re-analyzed the data from prior studies. This supplementary report presents the results of the additional analyses addressing classification accuracy, reliability, and criterion-related validity evidence. For ease of reference, we…

The problem investigated in this quantitative study was that schools in a small, rural East Texas town were falling below acceptable ratings in reading on the Texas Assessment of Knowledge and Skills (TAKS) and the State of Texas Assessment of Academic Readiness (STAAR). Researchers have found that constructive-based learning environments (CBLEs)…

This study investigates the relationship between School Library and Students' achievement on a population sample of 9896 Schools. Many international researches confirmed the importance of the School Library for the Students learning. Recently the IEA PIRLS survey has revealed a positive relationship between the Reading comprehension performance…

There are no salient word spaces in Mandarin Chinese. Thus, it is unclear whether word spacing information differentially affects the reading speed of children with and without reading difficulties (RD). In the present study, native Chinese-speaking children of differential reading abilities were tested with Chinese text in un-spaced versus spaced…

Although instruction has been shown to be effective at increasing vocabulary knowledge and comprehension, factors most important for promoting the acquisition of novel vocabulary are less known. In addition, few vocabulary studies have utilized models that simultaneously take into account child-level, word-level, and instructional factors to…

Modeling growth for students with significant cognitive disabilities (SWSCD) is difficult due to a variety of factors, including, but not limited to, missing data, test scaling, group heterogeneity, and small sample sizes. These challenges may account for the paucity of previous research exploring the academic growth of SWSCD. Our study represents…

The purpose of this study was to examine the directionality of the relationship between text reading prosody and reading comprehension in the upper grades of primary school. We compared 3 theoretical possibilities: Two unidirectional relations from text reading prosody to reading comprehension and from reading comprehension to text reading prosody…

A group of 50 skilled readers and a group of 50 less-skilled readers of Grade 5 matched for age and intelligence and selected on the basis of their proficiency in reading comprehension were tested for their competence in word reading and the processes of attention, simultaneous coding, successive coding and planning at three levels, i.e.,…

We examined the developmental relations between knowledge of reading strategies and reading comprehension in a longitudinal study of 312 Dutch children from the beginning of fourth grade to the end of fifth grade. Measures for reading comprehension, reading strategies, reading fluency, vocabulary, and working memory were administered. A structural…

Comprehensive models of derived polymorphemic word recognition skill in developing readers, with an emphasis on children with reading difficulty (RD), have not been developed. The purpose of the present study was to model individual differences in polymorphemic word recognition ability at the item level among 5th-grade children (N = 173)…

This study investigated the complexity of leveled passages used in four classroom reading assessments. A total of 167 passages leveled for Grades 1-6 from these assessments were analyzed using four analytical tools of text complexity. More traditional, two-factor measures of text complexity found a general trend of fairly consistent across-grade…

Instructional influences on productive use of academic vocabulary were investigated among 460 mostly African American and Latina/o fifth graders from 36 classrooms in eight public schools serving low-income families. Students received a 6-week unit on wolf management involving collaborative group work (CG) or direct instruction (DI). The big…

This quantitative, correlational study investigated the relationship between the North Carolina End of Grade Assessment of Reading Comprehension (NCEOG) and mClass Reading 3D assessment in a North Carolina elementary school. It especially examined the degree to which mClass Reading 3D measures predict scores on the reading comprehension portion of…

This study investigated the effect of using reciprocal teaching intervention strategy on improving reading comprehension of reading disabled students in primary five. A total of 66 students identified with RD participated. The sample was divided into two groups; experimental (n = 33 boys) and control (n = 33 boys). ANCOVA and T test were employed…
