Education decisionmakers need access to the best evidence about the effectiveness of education interventions, including practices, products, programs, and policies. It can be difficult, time consuming, and costly to access and draw conclusions from relevant studies about the effectiveness of interventions. The What Works Clearinghouse (WWC)…

Intervention against cyberbullying and other risks associated with the misuse of ITC and social networks is an important social demand. The 'Asegúrate' Program tries to support teachers in this intervention. This research shows the impact of the program among those that have shown to be less sensitive in other studies: cyber-aggressors.…

Background: Despite the importance of breakfast consumption, breakfast skipping is common among Canadian youth. This study examines how changes to school-based breakfast programs are associated with breakfast-skipping behavior. Methods: Using school-level longitudinal data from Year 1 (Y[subscript 1]: 2012-2013) and Year 2 (Y[subscript 2]:…

Many states have scaled up School-Wide Positive Behavioral Interventions and Supports (SW-PBIS) with the goal of improving student behavior and academic outcomes. Although the effects of SW-PBIS on behavioral and discipline outcomes have been promising, the findings for academic achievement have been inconclusive and are often limited to…

Objective: Assess impact and feasibility of a Tobacco-Free Ambassador Program on campus policy compliance. Participants: Trained Ambassadors made 253 visits to campus sites over 15 months to observe and/or approach violators. Methods: Policy violators were observed at 23 locations during Wave 1 (April-June 2012) and/or Wave 2 (April-June 2013).…

This ex-post-facto quasi-experimental research design was conducted by selecting a convenient sample of approximately 2,000 3rd grade ELLs who took the regular reading and math English STAAR test during the 2014-15 school year in an urban southern Texas school district. This study was conducted using a quantitative research method of data…

This study evaluated the effectiveness of Mental Health First Aid (MHFA) program in improving mental health knowledge of the general public in Hong Kong. Methods: A quasi-experimental design was adopted whereby…

Design-based methods have recently been developed as a way to analyze data from impact evaluations of interventions, programs, and policies. The impact estimators are derived using the building blocks of experimental designs with minimal assumptions, and have good statistical properties. The methods apply to randomized controlled trials (RCTs) and…

A new design-based theory has recently been developed to estimate impacts for randomized controlled trials (RCTs) and basic quasi-experimental designs (QEDs) for a wide range of designs used in social policy research (Imbens & Rubin, 2015; Schochet, 2016). These methods use the potential outcomes framework and known features of study designs…

Design-based methods have recently been developed as a way to analyze data from impact evaluations of interventions, programs, and policies (Imbens and Rubin, 2015; Schochet, 2015, 2016). The estimators are derived using the building blocks of experimental designs with minimal assumptions, and are unbiased and normally distributed in large samples…

Most of the students who set out to earn degrees in community colleges never do. Interventions that simplify the complex organizational structures of these schools are promising solutions to this problem.
