More research is needed to understand the effects of school-based mindfulness programs in the years before adolescence, which represent a critical juncture and transitional period of development. The present study investigated mindfulness with elementary school students using random assignment and objective measures. The sample included 292 5th…

Background: Since returning to in-person instruction after the emergence of COVID-19 schools have seen a dramatic increase in the number of students chronically absent, with data indicating a greater increase for low-income, Black, and Hispanic students. Given the role of school attendance in both promoting positive educational outcomes as well as…

Boys and girls sit together in most classrooms, but do they interact? Based on forty-year-old evidence, coeducational classes may not be coeducational but instead be segregated by gender, which may undermine student success. Our goal is to answer this question in today's classrooms. We used longitudinal data to assess gender segregation in 26…

This report summarizes the results of kindergarten through fifth grade students' academic achievement outcomes in mathematics and science following four years of campus-level participation in the Launching Elementary Academic Foundations (LEAF) to STEM program. The LEAF to STEM Program consists of three key components that were adapted for K-5…

Following a randomized controlled trial that showed effectiveness of an equity-centered positive behavioral interventions and supports (PBIS) professional development intervention on student discipline in elementary schools, we studied the extent to which the intervention had differential effects on individual teachers' use of exclusionary…

A Q-matrix is a binary matrix that defines the relationship between items and latent variables and is widely used in diagnostic classification models (DCMs), and can also be adopted in multidimensional item response theory (MIRT) models. The construction process of the Q-matrix is typically carried out by experts in the subject area of the items…

The purpose of this study was to examine the relation between teachers' reports of classroom adversity, a measure of classroom hardship, and student problem behavior in a sample of students with or at risk of emotional/behavioral disorders. We also examined the extent to which this relation varied as a function of multiple domains of classroom…

The aim of this study was to explore how the Coding as Another Language (CAL) curriculum, developed by Boston College's DevTech Research Group and utilizing the ScratchJr app, impacted students' computational thinking, coding skills, and reading comprehension. To accomplish this, the research team randomly assigned thirteen schools in a…

Student motivation to write is a pivotal factor influencing their writing achievement. However, individual motivation to write is not independent of the learning environment. It also is crucial for teachers to develop their own efficacy, knowledge, and ability in writing and writing instruction to help them utilize effective instructional methods…

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…

This report derives its findings from Summer/Fall 2023 phone interviews with 22 facilitators and eight administrators following their participation in Math for All during the 2022-23 school year. The findings, summarized below, provide insight into the implementation experience, including challenges, areas of success, and plans for sustaining and…

This study examined: (1) school-based avoidance among students with problematic anxiety, (2) teachers' levels of accommodation of avoidant behaviour, and (3) the relation between teacher accommodation and student avoidance and anxiety. Participants included 31 elementary school students with problematic anxiety (mean age = 7.7 years; range 5-11;…

This study utilized a partially nested randomized control design to investigate the impact of Fusion, a first grade math intervention. Blocking on classrooms, students were randomly assigned to one of three conditions: a Fusion two student group, a Fusion five student group, or a no treatment control group. Two primary research questions were…

Semantic knowledge accumulates through explicit means and productive processes (e.g., analogy). These means work in concert when information explicitly acquired in separate episodes is integrated, and the integrated representation is used to self-derive new knowledge. We tested whether (a) self-derivation through memory integration extends beyond…
