Background: Heightened familial stress and distress during the COVID-19 pandemic may lead to increased negative parenting practices, particularly for parents with substantial adverse childhood experiences (ACES). Objective: To determine whether families' COVID-19-related distress is associated with young children's emotional/behavioral functioning…

In causal mediation studies that decompose an average treatment effect into indirect and direct effects, examples of post-treatment confounding are abundant. In the presence of treatment-by-mediator interactions, past research has generally considered it infeasible to adjust for a post-treatment confounder of the mediator-outcome relationship due…

Developmental researchers commonly utilize longitudinal data to decompose reciprocal and dynamic associations between repeatedly measured constructs to better understand the temporal precedence between constructs. Although the cross-lagged panel model (CLPM) is commonly used in developmental research, it has been criticized for its potential to…

The purpose of this study was to examine the relation between externalizing behavior and peer reputations of kindergarten through third-grade students (N = 35, from 18 classrooms) with or at risk for Emotional and Behavioral Disorders (EBDs). We also examined the extent to which this relation varied as a function of teacher delivery of praise. A…

The purpose of this study was to explore the paths by which word-problem intervention, with versus without embedded pre-algebraic reasoning instruction, improves word-problem performance. Students with mathematics difficulty (MD; n = 304) were randomly assigned to a business-as-usual condition or one of two variants of word-problem intervention.…

Augmented reality (AR), where digital holograms are layered over the real world, is rapidly being applied to different educational domains, including mathematics education. However, little is known about how AR can be effectively designed for collaborative use. There are both practical and theory-based reasons to set up collaboration in AR in…

During childhood, the ability to limit problem behaviors (i.e., externalizing) and the capacity for cognitive regulation (i.e., executive function) are often understood to develop in tandem, and together constitute two major components of self-regulation research. The current study examines bi-directional relations between behavioral problems and…

In this meta-analysis of 54 longitudinal studies with over 58,000 students in kindergarten through 12th grade, we examined the predictive nature of early numeracy measured at or before the first year of formal schooling in relation to later mathematics. Results showed that early numeracy significantly predicted mathematics measured after 6 months…

Math anxiety has been found to negatively correlate with math achievement, affecting students' choices to take fewer math classes and avoid math educational opportunities. Educational technology tools can ameliorate some of the negative effects of math anxiety. We examined students' math anxiety, effort in an educational technology platform, and…

The purpose of this study was to investigate the association between students' social-emotional behavior and their later academic outcomes from a person-centered perspective. To better inform social-emotional learning intervention practices, a person-centered approach was used to identify students' social-emotional behavior profiles based on seven…

This study describes the rationale, design, development, and technical properties of SELweb MS, a direct assessment of social and emotional competencies in middle school students. Assessment and item design were iteratively developed with input from youth and experts to measure five domains: Self-Awareness, Self-Management, Social Awareness,…

Students' social-behavioral competencies are foundational to development. This longitudinal study identified associations between parent-teacher and student-teacher relationships, and children's social skills and problem behaviors at a single timepoint and over time. It involved 316 students and their parents and teachers across Grades 1 through…

Aim: There is a lack of evidence-based tools for measuring problem-solving in young children with motor delays. The purpose of this study was to evaluate the construct validity and responsiveness of the Assessment of Problem-Solving in Play. Methods: 125 young children (10.72, SD 2.62 months) with mild, moderate, and severe motor delays were…

This study investigated whether parents and kindergarten children show concurrent and time-lagged physiological synchrony during dyadic interaction. Further, we tested whether parent-child behavioral co-regulation was associated with concurrent and time-lagged synchrony, and whether synchrony varied by the type of interaction task. Participants…

Evidenced-based mathematics interventions are critical for supporting students with mathematics difficulties. In research and practice, collecting implementation fidelity is important for ensuring that all the core components of the intervention are implemented as designed. Historically, implementation fidelity has been defined as multi-faceted…
