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…

We investigate the effectiveness of an active learning curriculum designed for an upper division Biochemistry series at a large, public research university. The goal was to determine how effective this format was when compared to a parallel conventional course, and to see if the active learning series can be run with limited resources (one…

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…

Given the widespread use of non-experimental (NE) methods for assessing program impacts, there is a strong need to know whether NE approaches yield causally valid results in field settings. In within-study comparison (WSC) designs, the researcher compares treatment effects from an NE with those obtained from a randomized experiment that shares the…

More aggregate data on school performance is available than ever before, opening up new possibilities for applied researchers interested in assessing the effectiveness of school-level interventions quickly and at a relatively low cost by implementing comparative interrupted times series (CITS) designs. We examine the extent to which effect…

Tools for evaluating the quality and rigor of single case research designs (SCD) are often used when conducting SCD syntheses. Preferred components include evaluations of design features related to the internal validity of SCD to obtain quality and/or rigor ratings. Three tools for evaluating the quality and rigor of SCD (Council for Exceptional…

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…

Varying methods for evaluating the outcomes of single case research designs (SCD) are currently used in reviews and meta-analyses of interventions. Quantitative effect size measures are often presented alongside visual analysis conclusions. Six measures across two classes--overlap measures (percentage non-overlapping data, improvement rate…

Background: Recent studies indicate that parent education programs that include content to enhance parents' mental states may prove efficacious in improving parenting behavior and child outcomes. Objective: This study presents findings from a national evaluation of the "Active Parenting First Five Years" (FFY) program. This group-based…

With states and districts across the country implementing the Common Core State Standards, teachers have more opportunities than ever to collaborate around the shared goals of strengthening curriculum design, classroom practices, and student learning. Building from this premise, the Common Assignment Study (CAS) has brought together teams of…

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…

I review the research literature on parent satisfaction with private school choice programs providing vouchers, scholarships, or education savings accounts. The reviewed studies make use of parent surveys to measure satisfaction, often comparing the responses of parents of scholarship lottery winners to those of parents of students who lost…

New Leaders is an educational leadership organization and the mission is to ensure high academic achievement for all children, underscored by the commitment to racial equity, social justice, and an unwavering belief in the potential of every student. The rigorous and evidence-based approach to professional learning has been proven to work, with…
