Background: Race to the Top era teacher evaluation reforms sought to improve teacher effectiveness and, ultimately, student achievement through either accountability or developmental mechanisms (Donaldson, 2021). Quasi-experimental teacher evaluation studies find mixed results in urban and large-scale settings (Dee & Wyckoff, 2015; Steinberg…

Expanded Learning Time (ELT) is seen as one promising approach for improving academic achievement, particularly in the nation's chronically low-performing schools. Since 1995, Citizen Schools (CS) has developed and supported the implementation of its own ELT model. The CS ELT model uses an additional shift of educators and community volunteers to…

This paper describes the implementation of the online and f2f summer algebra courses that were delivered in summers 2011 and 2012. These data will be used to frame the impact results presented in an earlier paper. In particular, the paper will provide a detailed picture of how the online course was structured and the types of supports provided to…

Estimates of fidelity of implementation are essential to interpret the effects of educational interventions in randomized controlled trials (RCTs). While random assignment protects against many threats to validity, and therefore provides the best approximation to a true counterfactual condition, it does not ensure that the treatment condition…

Research on social and emotional learning (SEL) has largely focused on classroom interventions and student-­ and classroom­-level outcomes. Few studies have examined whole­-school and district-­level SEL implementations, or how to ensure that SEL programs are implemented effectively and sustained over time. This study examines both process…

In Belize, the percentage of untrained teachers (i.e. teachers with the equivalent of a high school education or less) is one of the highest in the region of Latin America and the Caribbean. In response to growing student cohorts, the increased demand for more classroom teachers has led to significant decrease in the proportion of trained teachers…

The concept of "implementation fidelity" is broadly used to capture the extent to which an intervention is executed as intended by the designers of the intervention (Century, Rudnick, & Freeman, 2010; Huntley, 2005, McNaught, Tarr, & Sears, 2010, Munter, 2010). Though implementation fidelity instruments are often used to assess…

The ESEA Blueprint for Reform states that teachers need "effective, ongoing, job-embedded, professional development that is targeted to student and school needs… [and] aligned with evidence of improvements in student learning." Unfortunately, the professional development approaches advocated, though sensible and compelling in theory,…

The purpose of the present study was to examine the effect that teacher choice of intervention has on their level of procedural implementation and quality of implementation. The following research questions helped to guide the study: (1) Do teachers randomly assigned to the intervention "choice" group have higher ratings of procedural fidelity…

Most school principals believe recess has a positive impact on the development of students' social skills and academic achievement. Research also suggests that physical activity and play during recess may be linked to improvements in both academic and prosocial behaviors (Centers for Disease Control and Prevention 2010). Recess, however, has been…

The purpose of this study was twofold: (1) to determine the efficacy of the Leveled Literacy Intervention program (LLI) in increasing reading achievement for K-2 students and (2) to examine LLI program implementation fidelity. This study evaluated LLI in two U.S. school districts and used a mixed-method design to address the following key research…
