Racial/ethnic and economic school segregation represent pervasive instantiations and perpetuators of educational inequity in the United States. Although the U.S. is becoming increasingly racially and ethnically diverse, schools are racially/ethnically isolated. Rising income and wealth inequity are also exacerbating economic school segregation.…

This study examined how children's moral reasoning in response to intergroup exclusion scenarios relates to inclusive attitudes and behaviors. A sample of 528 students (M[subscript age] = 9.19, SD = 0.90; 264 girls) in third through fifth grade participated in the "Developing Inclusive Youth" (DIY) program, which provided structured…

Core5 is a program that focuses on various student literacy skills, such as fluency, vocabulary, and comprehension. This report represents the…

The purpose of this study was to explore the relationship of the Leader in Me philosophy to students' equitable achievement in school, by measuring the academic achievement of third through fifth graders in suburban Missouri public schools. A secondary purpose of the study was to inform teachers and school leaders of effective strategies for…

Math programming that includes assessments to predict standardized mathematics scores can help evaluate student performance and growth during the academic year. ACALETICS® is a highly interactive, culturally inclusive mathematics program that utilizes posttests as continuous comprehensive assessments to evaluate student mathematical knowledge.…

This study explores whether teacher reports of executive functions predict change in reading performance (i.e., reading development) for elementary-aged students when controlling for direct assessments of executive functions and for teacher reports of students' literacy skills. Prior research has raised problems with the construct validity of…

Zearn Math is a popular software platform for K-8 mathematics learning, designed to enable all students to successfully access grade-level content. RAND researchers collaborated with Zearn, the product's developer, to design this evaluation. Then RAND conducted the study independently, randomly assigning 64 schools in an urban Texas district to…

Beginning in the fall of 2017, Maryland severely restricted the use of out-of-school suspensions in grades PK-2. The policy presented a valuable opportunity to examine the effects of state-level discipline policies. This study researched the effects of the suspension ban on student discipline outcomes (e.g., number and frequency of different…

Supporting student wellbeing in schools is increasingly becoming a global priority. However, research and initiatives primarily focus on general wellbeing rather than subject-specific experiences. Given the pervasive levels of mathematics anxiety, negative attitudes, and disengagement in mathematics education, we argue for a more contextualised…

This report focuses on the COVID-19 pandemic in the Kalamazoo Public Schools District in Kalamazoo, Michigan, which closed its doors to students from mid-March 2020 to June 2021. During this time, instruction transitioned from face-to-face to virtual, with students having three options for virtual instruction. In addition to individual KPS student…

Background: Over the last twenty years, retention has increased in popularity with policymakers who are concerned with student achievement and aim to end social promotion (i.e., the practice of advancing a student to the next grade level although they have not yet met the academic expectations of their current grade level). Despite calls to expand…

This study examines the experiences of six K-5 elementary school teachers in professional learning spaces for antiracism. Teachers from two elementary schools established school-university partnerships to begin antiracist work: one on a whole-school level, the other a group of teachers meeting voluntarily with university faculty. Given the paucity…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

Nationally representative data from the Early Childhood Longitudinal Study Kindergarten Class of 2011 (n = 14,370) were used to examine the grade-level and cumulative outcomes of school absenteeism between kindergarten and fifth grade for students' school performance in the United States. Students who were more frequently absent in any year of…
