Legislative smoking bans that prohibit smoking in public places have successfully reduced passive smoking in public areas. However, smokers only partially adhere to smoking restrictions in their homes. Young children are particularly vulnerable to exposure to tobacco smoke because they spend more time at home. In this study, we designed an…

This study reports the findings from a year-long randomized evaluation assessing the impact of assigning 62 classrooms in Nigeria to receive either blocked or interleaved math problem sets. Blocked practice sessions focused on a single skill at a time. Interleaved problem sets alternated between different skills within a practice session. On tests…

The primary purpose of this study was to determine the differences in the academic outcomes of first-year academically underprepared TN Promise-eligible college freshmen who participated in a college bridge program. A comparative research design was applied to existing data, including first-semester GPA, first-semester credit completion rate,…

Purpose: This study aims to investigate the formative evaluations of the training programmes of a Portuguese national railway public company for an entire calendar year. The aim is to uncover alternative configurations for the design of training programmes to create better levels of evaluation. This study is based on the following research…

Appropriately designed educational programmes would help medical students gain confidence and mitigate fears of internship. The aim of this pilot study is to compare the preparedness of interns for hospital practice before and after attending a two-day "Interns Orientation Programme." A small batch of interns in a tertiary care teaching…

In experimental evaluations of health and social programs, the role of dosage is rarely explored because researchers cannot usually randomize individuals to experience varying dosage levels. Instead, such evaluations reveal the average effects of exposure to an intervention, although program exposure may vary widely. This article compares three…

Dual enrollment programs across the nation have gained positive attention for increasing access to affordable higher education, elevating academic rigor, and encouraging timely degree completion. However, dual enrollment programs differ significantly in design. This study analyzed the college transfer sector of the Career and College Promise (CCP)…

Recent research on statewide voucher programs in Louisiana and Indiana has found that public school students that received vouchers to attend private schools subsequently scored lower on reading and math tests compared to similar students that remained in public schools. The magnitudes of the negative impacts were large. A case to use taxpayer…

We compare the environmental performance of voluntary environmental programs (VEPs) with different attributes. Using club theory, we argue that the differential performance of VEPs is due in part to their specific design attributes that will either enhance or diminish their ability to improve both targeted and untargeted environmental impacts. We…

Although video cases and video clubs have become popular forms of teacher professional development, there have been few systematic investigations of designs for such programs. Programs may vary according to (a) whether teachers watch videos of their own/their peers' instruction, or whether teachers watch stock video of unknown teachers; and (b)…

This study uses meta-analytic methods to explore programmatic moderators or common factors of the effectiveness of marriage and relationship education (MRE) programs. We coded 148 evaluation reports for potential programmatic factors that were associated with stronger intervention effects, although the range of factors we could code was limited by…

Purpose: English learner (EL) education policy has long directed schools to address EL students' linguistic "and" academic development without furthering inequity or segregation. The recent Every Student Succeeds Act reauthorization expresses a renewed focus on evidence of equity, effectiveness, and opportunity to learn. We propose that…

This paper considers one challenge from recent emphasis on rigorous research for decision-making in education: the interpretation of non-replicated findings. Under Clinton and Bush, the federal government called for and funded highly rigorous research. The "gold-standard" for research was randomized-control trials (RCTs), which…

This article investigates the differences in academic achievement trajectories from elementary through middle school among English Learner (EL) students in four different instructional programs: English Immersion (EI), Transitional Bilingual (TB), Developmental Bilingual (DB), and Dual Immersion (DI). Comparing students with the same parental…
