The purpose of this study was to examine the effects of MoBeGo, a mobile self-monitoring app, on the initial and sustained academic engagement and disruptive behavior of third- to eighth-grade students with challenging behavior. Student-teacher pairs (N = 57) were randomly assigned to the treatment (MoBeGo) or control (business-as-usual)…

When people are exposed to information that leads them to overestimate the actual amount of genetic difference between racial groups, it can augment their racial biases. However, there is apparently no research that explores if the reverse is possible. Does teaching adolescents scientifically accurate information about genetic variation within and…

Recent methods have sought to improve precision in randomized controlled trials (RCTs) by utilizing data from large observational datasets for covariate adjustment. For example, consider an RCT aimed at evaluating a new algebra curriculum, in which a few dozen schools are randomly assigned to treatment (new curriculum) or control (standard…

Interventions often require multiple decisions to improve outcomes for every student. Whether the decision to implement a practice, tailor an existing protocol, or change approaches, these decisions should be based on individual variables and outcomes via a sequence of treatment. To develop adaptive interventions that have sufficient evidence to…

Introduction: Youth in disadvantaged urban areas are frequently exposed to chronic stress and trauma, including housing instability, neighborhood violence, and other poverty-related adversities. These exposures increase risk for emotional, behavioral, and academic problems and ultimately, school dropout. Schools are a promising setting in which to…

In this work, we describe a new statistical method to improve the detection of treatment effects in interventions. We call our method TAME (Trained Across Multiple Experiments). TAME takes advantage of multiple experiments with similar designs to create a single model. We use this model to predict the outcome of the dependent variable in unseen…

Educational stakeholders are keen to know the magnitude and importance of different interventions. However, the way evidence is communicated to support understanding of the effectiveness of an intervention is controversial. Typically studies in education have used the standardised mean difference as a measure of the impact of interventions. This…

We report the results of a preregistered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no 2 consecutive problems require the same…

An impediment to conducting high-quality quantitative research studies in education is the paucity of valid measures of learning gains. Studies often seek to investigate students' deep, conceptual understanding yet many measures assess only surface, procedural understanding. One reason is that the development of validated measures of conceptual…

Student-teacher relationships are important to student outcomes and may be especially pivotal at the high school transition and for minoritized racial/ethnic groups. Although interventions exist to improve student-teacher relationships, none have been shown to be effective among high school students or in narrowing racial/ethnic disparities in…

Seventh- and 8th-grade students in a within-teacher randomized control study read from visual-syntactic formatted text for 44 min per week over the course of 1 year. On the annual state assessment, we found small statistically significant improvements on the overall English Language Arts scaled score (ES = 0.05, p < 0.05) and the writing…

This study investigates the impact of an informal science outreach programme built around theories of identity formation and self-efficacy on middle school girls' science affinities. A lottery-based, randomised control trial was used to identify programme effects on four science affinity outcomes: science interests, efficacy with science, science…

Classroom observations have long been considered a necessary component of Attention-Deficit/Hyperactivity Disorder (ADHD) evaluations. Yet, research evaluating the utility of observational ratings in ADHD assessment is limited. This study examined the contributions of the Behavioral Observation of Students in Schools (BOSS) to ADHD assessment by…

Students with disabilities are often included in general education social studies classes, but these classes can differ in the achievement level of the overall class, including wide variation in content-related background knowledge, reading achievement, or both. The purpose of this study was to examine how background knowledge and reading…

A growing body of correlational research finds a relationship between self-efficacy--beliefs in one's capabilities--and academic success. But few studies have investigated whether self-efficacy is causally related to academic success. We hypothesized that an experience of success would promote self-efficacy in junior high school students and would…
