This study examined the effect of small class size intervention on student outcomes using reading achievement scores as measured by the Comprehensive Test of Basic Skills (CTBS), a standardized, norm-referenced test, while controlling for independent variables inclusive of students' gender, race, socioeconomic status (SES), and environment. This…

Civil, informed debate is essential for any healthy democracy. This is truer than ever judging from the often uncivil, fact-free public discourse one sees too often on television and social media. But does participation in formal debate training improve educational outcomes? While policy debaters historically have come from high-income public…

This report evaluates the effects of Lexia[TM] Core5[TM] Reading (Core5) -- a product of Lexia Learning Systems -- on the reading achievement of students in grades 3-5 during the 2021-2022 academic year. Core5 is a program that focuses on various student literacy skills, such as fluency, vocabulary, and comprehension. This report represents the…

We analyzed a population-based cohort (N = 10,922) to investigate the onset and stability of racial and ethnic disparities in advanced (i.e., above the 90th percentile) science and mathematics achievement during elementary school as well as the antecedent, opportunity, and propensity factors that explained these disparities. About 13% to 16% of…

The present study examined Latinx school readiness and 3rd grade student achievement, considering differences based on social categories of gender, race, ethnicity, and home language. The sample included 683 racially diverse children (M[subscript age] = 4.94; SD = 0.57) of Dominican- or Mexican-origin from Spanish-English or Spanish-only…

The Office of English Language Acquisition (OELA) has synthesized key data on English learners (ELs) into two-page sheets on a variety of subjects. This fact sheet focuses on: (1) States Reporting American Indian/Alaska Native Languages as One of the Top Five Most Common English Learner Languages Spoken: School Year 2016-17; (2) Number of English…

This research tested a mediation model, examining whether individual differences in mothers' school readiness beliefs influenced home literacy practices and children's later academic achievement among African American (n = 114) and primarily Mexican origin Latina mothers (n = 164) and their children. Mothers of children ages 3-4 years reported…

Our purpose is to proffer QuantCrit methodological approaches to interrogate notions of statistical practice by convention. We present two approaches to meta-analysis and mean effect size calculations for student achievement. The first approach is the conventional approach which applies between-group differences to calculate effect sizes…

In response to COVID-19, U.S. students learned remotely from mid-March to June 2020. At the start of academic year 2020--21, many schools remained remote but others--primarily Catholic and other private schools--reopened. We consider Catholic schooling as a proxy for in-person instruction and use national data from Renaissance Star and MAP Growth…

The purpose of this study was to investigate the differences in the reading assessment performance between Black male students and their same grade level counterparts. Assessment results and teacher perceptions were analyzed to reveal instructional supports to demonstrate reading achievement. The mean scores and pass rates based on race and gender…

Because standardized tests in science are not given to PreK-3 students in Ohio, this report examined the longitudinal effects of learning from a teacher who had participated in the NURTURES professional development program. Specifically, it looked at the effects on students' mathematics and reading learning in grades 2-5 and science learning in…

The schooling disruptions due to the COVID-19 pandemic continue to reverberate across the K-12 educational system more than a year after schools closed for in-person instruction. In this study, we examined the aftermath of these disruptions by modeling student achievement trends prior to and during the pandemic, with particular focus on growth in…

While the ongoing academic impacts of the COVID pandemic in grades 3-8 has been well documented, far less is known about its effects on students who were in pre-K or kindergarten when the pandemic started in March 2020. In this brief, we focus on students who were in first and second grade in the 2021-22 school year, and for whom the majority of…

COVID-19 significantly impacted the educational and home environments for students throughout the Commonwealth of Virginia in ways that may have impacted student learning, as measured by standardized exams. We analyze statewide, student-level administrative and assessment data on the Standards of Learning (SOL) reading and math tests for the…

In 2014, the municipal water source in Flint, Michigan was switched, causing lead from aging pipes to leach into the city's drinking water. While lead exposure in Flint children increased modestly on average, some children were exposed to high lead levels. Surveys of Flint residents show the water crisis was also associated with increased levels…
