LXD Research analyzed data from 405 students from kindergarten through first grade who either participated in using the 95 Phonics Core Program (95PCP) or served as comparison students in a school district in AZ during the school year 2022-2023. This product adds explicit and systematic phonics instruction to the daily reading block. The…

Background/Context: Observational studies often employ regression discontinuity (RD) designs and multiple control-group designs to explore the causal quantities of interest. RD designs assess policy and program effectiveness by assigning subjects to treatment based on whether they exceed a pre-defined cutoff. RD designs are classified into two…

Well-designed computer or app-based instruction has a number of potential benefits (eg increasing accessibility and feasibility of high-quality instruction, reducing time and resources required for training expert delivery, saving instructional time). However, variation in implementation can still affect outcomes when using educational technology.…

Background/Context: Some observational studies involve multiple layers of treatment selection, specifically in the context of the extended time accommodation (ETA) for English language learners (ELLs). In ETA settings, the first selection occurs due to the eligibility rule, where students whose ELL English proficiency is below a certain threshold…

The experiences and learning opportunities children are exposed to in pre-K give them a boost as they enter school. However, the positive effects of pre-K attendance on children's academic and cognitive skills become smaller and sometimes disappear by third grade due to non-attenders "catching-up" to their peers. To make pre-K programs…

In recent years, children and adolescents have spent more time sitting and engaging in less physical activity than recommended by health authorities. Despite widespread efforts to promote physical activity through school-based programs, the impact of specific intervention programs often remains untested. Therefore, in this pilot study, the effects…

This study tested whether effects of a preventive intervention delivered in elementary school showed benefits for the young adult offspring of intervention recipients over 20 years later. The Raising Healthy Children (RHC) intervention, trialed in 18 public schools in Seattle, Washington, from 1980-1986 (grades 1-6), sought to build strong bonds…

Guided by the conceptual framework of the Comprehensive School Physical Activity Program (CSPAP), the purpose of this study was to determine if a walking club after school for teachers and students increased physical activity levels, reduced stress, and improved mood. The participants were 51 (67% male, 33% female) fourth- to eighth-grade students…

We present experimental evidence on the impact of a multi-faceted program that integrates technology-aided instruction, teacher training and coaching, community ownership, and free primary education. Our setting is three districts in rural Zambia, where we randomly assigned the program across 30 treatment and 33 control schools. The results show…

The purpose of this study was to explore the effectiveness of a universal classroom-based social-emotional learning (SEL) program for first grade students. Forty classrooms from 13 elementary schools across 3 states participated in the trial. Teachers in classrooms randomly assigned to the implementation condition were provided with free access to…

Small group social skills training (SST) is recommended to improve the social behavior and peer relations of rejected children, but child responses vary. This study explored variation in intervention experiences that emerged in a large study of a school-based SST program for peer-rejected children and associations with program outcomes. One…

The purpose of this ex post facto study was to compare the end of year GPAs of 8th grade underachieving students who participated in Career and Technical Education programming through the Memphis Ambassadors Apprentice Program to those who did not. Introducing Career and Technical Education programs and activities to students at a young age…

The Countdown to Kindergarten (CTK) program was developed to increase family awareness of kindergarten expectations, create a positive relationship with families, and support smooth school transition and kindergarten readiness for children who were from diverse backgrounds and/or had adverse experiences. We used a mixed methods design to study the…

Mental health during childhood is a growing social challenge with important implications for optimal development. Social and Emotional Learning (SEL) interventions have been shown to prevent problems related to psychological maladjustment, as well as promote emotional well-being. This article aims to provide evidence for the impact of RULER…

This study examines the effects of interactive book reading (IBR) implementations on typically developing students' social acceptance of students with special needs. Since inter-group and within-group comparisons are to be made, a split-plot design of factorial designs was used in the study. In this study, the Social Acceptance Scale (SAS) was…
