This article reports on two professional development programs for mathematics teachers and their effects on student achievement. The projects' design and their implementation within a larger municipality in Sweden, working together with over 90 teachers and 5000 students in elementary school, are described by using a set of core critical features…

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…

Purpose/Objectives: The purpose of this study was to determine if mushroom blended recipes are an acceptable option for use in the school food program. The palatability and acceptance of mushroom-soy-beef blend burgers among school-aged children was tested. Methods: Students in grades 2 through 8 were invited to participate in a taste test.…

This study examined the psychometric properties and measurement invariance of the Arabic version of "My Class Activities" (MCA), an instrument designed to measure students' perceptions of interest, challenge, choice, and enjoyment in classrooms. Scores of 3,516 Sudanese students in Grades 2 to 8 were used. Confirmatory factor analysis…

Notwithstanding dramatically low levels of professed religiosity in Western Europe, the religious school sector continues to thrive. One explanation for this paradox is that nowadays parents choose religious schools primarily for their higher academic reputation. Empirical evidence for this presumed denominational advantage is mixed. We examine…

All native speakers of Arabic read in a language variety that is remarkably distant from the one they use in everyday speech. The study tested the impact of this distance on reading accuracy and fluency by comparing reading of Standard Arabic (StA) words, used in StA only, versus Spoken Arabic (SpA) words, used in SpA too, among Arabic native…

This study followed the development of reading speed, reading accuracy, and spelling in transparent Finnish orthography in children through Grades 2, 3, and 8. We compared 2 groups of children with familial risk for dyslexia--1 group with dyslexia (Dys _FR, n = 35) and 1 group without (NoDys_FR, n = 66) in Grade 2--with a group of children without…

The science vocabulary from a science curriculum standards document (Ministry of Education Ontario, 2007) was classified by morphological developmental level and compared to the grade level topics of the curriculum (grades 1 to 8). Descriptive statistical analyses highlight the complex nature of science vocabulary and the incompatibilities between…

To determine whether formative writing assessments that are directly tied to everyday classroom teaching and learning enhance students' writing performance, we conducted a meta-analysis of true and quasi-experiments conducted with students in grades 1 to 8. We found that feedback to students about writing from adults, peers, self, and computers…

This study investigated children and adolescents' school performance over time focusing on two variables that may influence it: developmental context and gender. The sample comprised 627 participants (M[subscript age]?=?11.13, SD?=?1.8), 51% of them female, from grade one to eight, living either with family (n?=?474) or in care institutions…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

This study investigates change in the home language environment of Language Minority (LM) learners between kindergarten and eighth grade, drawing on data from the National Center for Education Statistics' Early Childhood Longitudinal Study-Kindergarten (ECLS-K) Cohort. The analytic sample included 1,538 children whose parents reported a language…

The purpose of this study was to examine the characteristics and predictive factors for children receiving special education services, and if they received special education services, factors associated with them discontinuing those services before eighth grade. In addition, a second purpose was to determine whether there are differences in the…

This paper reports the results of a descriptive study on the use of a technology-enhanced formative assessment system called Accelerated Math (AM) for ELLs and their native-English-speaking (NES) peers. It was comprised of analyses of an extant database of 18,549 students, including 2,057 ELLs, from grades 1 through 8 across 30 U.S. states. These…
