Previous literature reported that Black students receive out-of-school suspensions (OSSs) and expulsions at disproportionately higher rates and have lower test scores than White students. This study provides recent evidence on the relation between racial disparities in discipline and in achievement, with particular focus on achievement gains, in…

Many U.S. students possess only a weak knowledge of fraction arithmetic. I hypothesize that textbooks are a critical reason for students' poor performance on fraction arithmetic. This is not because of what textbooks contain but rather because of what they lack. Distributions of fraction arithmetic problems in textbooks are imbalanced, with…

BACKGROUND: The COVID-19 pandemic triggered a worldwide socio-sanitary crisis, continuing to impact societies worldwide. With many school systems shifted to online education, the current study presents a unique opportunity to investigate relevant phenomena related to serious health issues during the schooling and later in life, cyberbullying and…

The purpose of this quantitative ex post facto study was to determine if, and to what extent, differences existed in pre-and-post math scores following the VMath intervention for Title I 6th, 7th, and 8th graders in the Southwestern United States. Three research questions guided this study: (1) is there a statistically significant difference in…

This article reports an empirical study aiming to investigate students' use of mathematics textbooks in Shanghai and England, with a comparative perspective. The study used mixed methods to collect the data through student questionnaire, student focus group interview and classroom observation. 161 Shanghai seventh- and eighth-grade students and…

We present two types of validity evidence to support inferences and decisions about use of easyCBMs in relation to state testing programs. The first type involves the use of Benchmarks in reading to use in making predictions of performance on the Smarter Balanced (SB) test. These predictions can be made both well in advance (several months) or…

This study examined the initial efficacy of World Generation (WorldGen), a Tier I social studies instructional approach for emergent bilingual (EB) students and their native English-speaking (non-EB) peers in Grades 6 and 7. WorldGen builds on prior research on instructional practices that have been associated with improved content knowledge and…

Drawing on the bioecological theory developed by Bronfenbrenner, the researchers of this study examined four environmental systems--microsystem, mesosystem, exosystem, and macrosystem--for gifted children in Israel as perceived by their parents, focusing on a comparison between rural and central contexts. The rural context comprises peripheral…

Sources of longitudinal achievement data are increasing thanks partially to the expansion of available interim assessments. These tests are often used to monitor the progress of students, classrooms, and schools within and across school years. Yet, few statistical models equipped to approximate the distinctly seasonal patterns in the data exist,…

The present research examined the joint effects of social, dimensional, and temporal comparisons on students' academic self-concepts and parents' beliefs about their children's competencies during students' transition phase from elementary school to junior high school. To this end, we tested the newly developed 2I/E model using longitudinal data…

The purpose of this study was to study the impact on student performance due to participation in the Catapult Learning Intervention program in the Mathematics and Reading services offered in a religious non-public school system in the Northeastern United States from grades 6-8. Student scaled scores from the NWEA MAP assessments administered at…

Using a dataset that includes over 17 million students from across all 50 states, we estimate the causal impact of making structural transitions into middle school (in grades 4, 5, 6, or 7) on student math and reading achievement trajectories. This dataset provides an ideal opportunity to engage in the valuable scientific practice of conducting…

Second Language Pragmatics (L2 pragmatics) research focused on the study abroad (SA) context points out the benefits of this context for second language (L2) pragmatic development while also illustrating the non-linearity of this development, as it is shaped by different contextual factors and individual differences. Nevertheless, this research…

This U.S. study evaluated the effects of a reading intervention for emergent bilingual students with significant reading difficulties in Grades 6 and 7 within a multisite randomized controlled trial. Emergent bilinguals were randomized to a researcher-provided intervention (n = 171) or business-as-usual comparison condition (n = 169). Results on a…
