The purpose of this article is to describe a 40+ year journey during which researchers have endeavored to design and evaluate an integrated, empirically based reading intervention for secondary students and to chronicle the lessons learned as well as suggest future directions for this type of work. Initial development of the intervention began in…

In 2016, Union County College began a four-year experiment with corequisite developmental mathematics as part of a grant from the U.S. Department of Education's First in the World (FITW) program. In this experiment, students assessed as needing to take developmental mathematics courses would be eligible to receive a waiver from their developmental…

In experimental evaluations of policy interventions, the so-called Bloom adjustment is commonly used to estimate the impact of the treatment on the treated. It does so by rescaling the estimated impact of the intention to treat--that is, the overall treatment-control group difference in outcomes for the entire experimental sample--by the…

An aspect of a study is considered a confounding factor if it is not possible to tell whether the difference in outcomes is due to the intervention, the confounding factor, or both. In What Works Clearinghouse (WWC) study reviews, certified reviewers look for a specific type of confounding factor: those that occur when a component of the study…

There are unique challenges to estimating causal effects of preschool for students with special needs that have not received attention in the literature. We revisit the Head Start Impact Study (HSIS) to illustrate that when and how special needs is defined has implications for the internal validity of and interpretation of special needs subgroup…

The evaluation of intervention effects is an important objective of educational research. One way to evaluate the effectiveness of an intervention is to conduct an experiment that assigns individuals to control and treatment groups. In the context of pretest/posttest designed studies, this is referred to as a control-group pretest/posttest design.…

Objective: This study aims to evaluate the impact of a community development program meant to improve living standards of poor rural families through income generating activities (IGAs) based on conditional cash transfers (CCTs) in Doti, Nepal. Method: We use cross-sectional field data from a sample of 392 families representative of the village…

The dissertation is an initial investigation of a peer mentoring program in a suburban high school in the southeastern United States. Additionally, the Peer Mentoring Program (PMP) study examined whether the Program improves academic performance and attendance, and decreases referrals. Utilizing an experimental design, a Participant and a…

This paper describes the impact of the One World in Schools human rights education programme on the attitudes, self-efficacy and intention to act of a sample of Georgian secondary school students (n = 303). For the evaluation, a mixed approach was applied, combining pre/post experimental/control group design, post-programme teacher and student…

Using research focused on best practices, focus group information, and data analytics, the Title V: Focus on Student Success (FOSS) Grant created a model for the development, implementation, and evaluation of a summer bridge program. Results included increased academic performance indicators in first-year Hispanic college students. Validation for…

The purpose of this research is to examine the effect of the "Incredible Years (IY) Child Training Program" on behavioral problems, social competence, and social problem-solving skills. The research was performed using a pretest-posttest experimental design with a control group to determine the effects of the IY program on the level of…

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…

Attending high-quality early childhood care and education (ECCE) is associated with higher cognitive and social-emotional skills, especially for children growing up in poverty, but access to high-quality ECCE is limited. This study capitalizes on the random assignment design of the Head Start Impact Study to better understand whether the…
