Determining the effectiveness of core mathematics curricula is foundational to evidence-based practice. Examining effectiveness heterogeneity is also crucial to better understanding mathematics achievement among English language learners (ELLs). In this study, we used a quasi-experimental design (difference-in-differences) to examine the impact of…

Energy concepts are taught in many schools, but children rarely have an opportunity to grapple with energy problems and work on their own solutions. This study explores the impacts of Connect Science, a service-learning (SL) program developed to enhance elementary students' energy literacy in the United States. Program impacts were explored within…

The goal of this study was to further evaluate the impact of IXL Math on math learning outcomes. Using a quasi-experimental design with matched treatment and control groups, this analysis utilized data from 312 public schools in Mississippi during the 2021-2022 school year. The middle school analysis included 272 schools (136 treatment, 136…

Research on mindfulness-based interventions (MBIs) has proliferated in recent years and the integration of mindfulness-based programs in school settings has been at the forefront of implementation research. Recent reviews of studies evaluating the efficacy of school-based mindfulness programs have produced mixed findings, which may in part be due…

Engaged in the evaluation of LDC tools since June 2011, UCLA's National Center for Research on Evaluation, Standards, and Student Testing (CRESST) is using multiple data sources and a quasi-experimental design to examine LDC implementation and impact in two cohorts of schools in two large, urban school districts. This report presents the results…

This study discusses the effectiveness of a science, technology, engineering, and math (STEM) program spanning grades six through eight in a traditional, urban school district located in Northeastern Ohio. The history and expressed need for STEM education within post-steel producing and economically depressed regions are discussed. Important…

Dating violence prevention programs have been understudied in Asia, including China. The current study sought to evaluate the feasibility of the Dating Compassion, Assessment, reFerral, and Education (CAFE) Ambassador Programme in China. This program is designed to enhance the behavioral intentions of Chinese students to help peers who are…

The goal of this study was to further evaluate the impact of IXL on learning outcomes in math and ELA. Using a quasi-experimental design with matched treatment and control groups, we analyzed data from 296 public schools in Colorado during the 2018-2019 school year. The analysis of IXL Math included 186 schools (93 treatment, 93 control), and the…

Pioneer Valley Books (PVB) contracted McREL International to investigate the effects of the third grade Literacy Footprints (LFP) guided reading system on English language arts (ELA) performance on state assessments. LFP is a research-based, comprehensive, small-group literacy tool that facilitates explicit and systematic guided reading…
