Statisticians have developed propensity score methods to improve generalizations from studies that do not employ random sampling. However, these methods rely on assumptions whose plausibility may be questionable. We introduce and discuss bounding, an approach that is based on alternative assumptions that may be more plausible. The bounding…

Transferring to a four-year institution is an important pathway to student success. Many students who enroll in community college intend to transfer to a four-year institution and subsequently earn a bachelor's degree. However, few students ultimately do, with low-income students transferring at lower rates than their peers. The Texas Transfer…

The purpose of this paper is to demonstrate Hispanic students' mathematics achievement growth rate in Inclusive science, technology, engineering, and mathematics (STEM) high schools compared to Hispanic students' mathematics achievement growth rate in traditional public schools. Twenty-eight schools, 14 of which were Texas STEM (T-STEM) academies…

The purpose of this investigation was to determine whether an experiential learning opportunity, specifically a study tour experience, would improve the cultural intelligence of prospective educational leaders and would challenge them to expand their own cultural understanding and behavior. Several prospective leaders who enrolled in a graduate…

The National Math + Science Initiative (NMSI) is a nonprofit organization committed to improving educational outcomes that traces its roots back to the early 1990s. NMSI's College Readiness Program (CRP) is a long-standing program with the goal of promoting STEM education in high schools to improve students' preparation for college. The three-year…

Researchers have identified inequities in dual-language bilingual education (DLBE) student participation, and with large-scale DLBE expansion, equitable student access is an increasingly important issue. In this study, I used a multimethod, multisite, comparative analysis to critically examine educator discourses addressing student participation…

Background: Few HIV/STI and pregnancy prevention programs for youth in American Indian and Alaska Native (AI/AN) communities have been rigorously evaluated despite sexual health disparities in this population. This study reports the evaluation of a culturally adapted Internet-based HIV/STI and pregnancy prevention program for AI/AN youth, Native…

In this investigation, the relationship between bilingual education program type (i.e., dual language programs or exit programs) and English Language Learner reading and mathematics test scores was examined. Data were obtained on English Language Learners who were enrolled in Grades 3, 4, 5, and 6 in Texas public schools for the 2008-2009,…

This report includes findings regarding demographic characteristics and academic outcomes of DELTA students; highlights emerging topics from the student, teacher, and staff surveys; and provides recommendations for future program implementation.

For the past decade, MDRC has evaluated a number of interventions designed to improve the outcomes of community college students, including enhanced counseling, learning communities, and financial incentives. Encouragingly, many of these strategies have produced positive effects, affirming that changes in institutional practices and policies can…

The problem of substance use among older youths is often disregarded in prevention research. The prevailing perception has been that prevention programming is developmentally inappropriate for those who are actively experimenting with substances. This project examines the differential effectiveness of youth-driven adaptations of the evidence-based…

Undecided undergraduate students are often considered to be "at risk" for lower academic performance and lower retention rates than students with declared majors. First-year seminars and learning communities are two interventions the retention literature suggests can enhance the success of at-risk students. This paper summarizes the…

Teen birth rates and teen pregnancy prevention strategies vary widely across individual states in the US, which has the highest overall teen birth rate among developed nations. California and Texas, the two most populous states currently accounting for a quarter of all teen births, have taken very different approaches to addressing adolescent…

The core work of the National Center on Scaling Up Effective Schools consists of four stages: identifying practices of highly effective high schools, designing interventions and transfer of practices, evaluating the intervention's implementation and effects, and evaluating implementation at scale. The purpose of this report is to describe the…
