Methods to estimate the causal effects of interventions are increasingly used in clinical medicine, public policy and social science. Using observational data, researchers can obtain causal treatment effect estimates without the ethical risks and time constraints that typically burden randomized experiments. The three studies in this dissertation…

Research increasingly seeks to answer the question: does special education work? This is different than asking if specific interventions have positive effects and instead aims to identify system-wide impacts. We systematically review published quantitative research on the impact of receiving special education services on student outcomes using…

Previous meta-analyses on peer tutoring have mainly included studies using treatment-control/comparison design and excluded studies that adopted pre-test-post-test design. However, some recent meta-analyses on other interventions adopting pre-test-post-test design revealed that certain crucial intervention moderators should be considered when…

This project seeks to answer questions about the effectiveness of early childhood programs in meeting their important goals, paying careful attention to the effectiveness of program variations (especially in regard to particular demographic and economic target groups). This review will be guided by two overarching questions: (1) How effective are…

This is a systematic review conducted of primary research literature published between 2007 and 2018 on the deployment and effectiveness of data analytics in higher education to improve student outcomes. We took a methodological approach to searching databases; appraising and synthesising results against predefined criteria. We reviewed research…

Schools need cost and resource-efficient strategies to improve the academic performance of students with autism spectrum disorder (ASD). High-quality research demonstrates peer-mediated interventions effects on improved social skills for students with ASD. However, effects of peer-mediated interventions on academic outcomes are less understood…

Charter schools are highly debated in policy and political discussions about delivering public education. As "laboratories of innovation" that often use lotteries to assign spots, they hold the potential to generate rigorous evidence about effective educational practices. This paper synthesizes and summarizes findings from charter…

We conducted a meta-analysis of single-subject research studies investigating the effectiveness of antecedent strategies grounded in behavioral momentum for improving compliance and on-task performance for students with autism. First, we assessed the research rigor of those studies meeting our inclusionary criteria. Next, in order to apply a…

Our study used a case-control matching design to assess the influence of a voluntary tutoring program in improving first-year students' Grade Point Averages (GPA). To evaluate program effectiveness, we applied case-control matching to obtain 215 pairs of students with or without participation in tutoring, but matched on high school GPA and…

Some researchers have characterized Universal Design for Learning (UDL) as a promising framework to provide diverse students with access to the general education curriculum, but to what extent and how have UDL-based interventions fulfilled that promise? The purpose of this review was to analyze studies that investigated impacts of UDL-based…

Peer tutoring is an instructional strategy that allows students to help one another learn content material through the repetition of key concepts. In more than 40 years of published studies, literature reviews, and meta-analyses of peer tutoring, this quantitative synthesis of the literature is the first to examine the impact of peer tutoring on…

The Montessori method is an attractive alternative to traditional education for many parents in the United States of America and abroad (Lillard & Else-Quest, 2006). There are between 4,000 and 5,000 private Montessori programs in the United States, and thousands more internationally (American Montessori Society, 2016; Lillard &…

Bui, Craig, and Imberman assessed the impact of gifted and talented programs on student achievement using regression discontinuity and random assignment to gifted magnet schools. In both analyses, they found minimal impact of the gifted and talented programs on student achievement. This commentary addresses two concerns associated with the study.…

This appendix is a companion to the "Study of Enhanced College Advising in Upward Bound: Impacts on Where and How Long Students Attend College" (ED615732) report. The appendix provides additional information about the "Find the Fit" enhanced advising strategies and the study that assessed its effectiveness when implemented…

Previous meta-analyses of the effects of peer tutoring on academic achievement have been plagued with theoretical and methodological flaws. Specifically, these studies have not adopted both fixed and mixed effects models for analyzing the effect size; they have not evaluated the moderating effect of some commonly used parameters, such as comparing…
