Evaluations of a large federally funded sexual risk avoidance education (SRAE) efforts in the USA have not been widely reported in the wake of funding cuts. The purpose of this study is to report results from a broad set of programmes to demonstrate the breadth of field effectiveness of these programmes. Twenty-seven separate community-based SRAE…

The authors conducted a meta-analysis and systematic review that examined 23 studies evaluating the effectiveness of child centered play therapy (CCPT) conducted in elementary schools. Meta-analysis results were explored using a random effects model for mean difference and mean gain effect size estimates. Results revealed statistically significant…

The focus of this article is two-fold. First, it describes a model that can be used to guide the evaluation of teacher professional development. The model combines important components of existing models and incorporates the use of students' perceptions for examining teacher change. Second, the article reports the evaluation of a teacher…

This study examined whether attending a Knowledge is Power Program (KIPP) middle school improved students' reading, math, social studies, and science achievement for up to 4 years following enrollment. The study reported that students attending KIPP middle schools scored statistically significantly higher than matched students on all of the state…

This policy brief summarizes the positive results of a rigorous evaluation of Reading Partners, a widely used program that offers one-on-one tutoring provided by community volunteers to struggling readers in low-income elementary schools. A total of 1,265 students in 19 schools in three states were randomly assigned to receive Reading…

Our study capitalized on a unique natural experiment rather than a researcher-designed, randomized experiment whereby, thanks to the Australian Government's Digital Education Revolution, half of grade 9 students in 2008 received laptops and half did not. Consequently in late 2011, when these students sat for their grade 12 external examinations…

This NFER report has been produced for the Education Endowment Foundation and its evaluation of a speaking and listening intervention combining two programmes: the Vocabulary Enrichment Intervention Programme (VEIP) and the narrative Intervention Programme (NIP). The intervention was used with pupils who needed extra support to improve their…

"Thinking Reader" is a software program for students in Grades 5-8 that incorporates elements commonly identified in policy reports as being key components of effective adolescent literacy instruction. This evaluation of the impact of "Thinking Reader" use by Grade 6 students focused on two confirmatory research questions about…

This "What Works Clearinghouse Procedures and Standards Handbook (Version 3.0)" provides a detailed description of the standards and procedures of the What Works Clearinghouse (WWC). The remaining chapters of this Handbook are organized to take the reader through the basic steps that the WWC uses to develop a review protocol, identify…

The purpose of this program evaluation was to determine the impact of a school-based, job-embedded professional development program on elementary and middle school teacher efficacy for technology integration. Participant bi-weekly journal postings were analyzed using Grappling's "Technology and Learning Spectrum" (Porter, 2001) to…

We evaluated the cost-effectiveness of Struggling Schools, a user-generated approach to Comprehensive School Reform implemented in 100 low achieving schools serving disadvantaged students in a Canadian province. The results show that while Struggling Schools had a statistically significant positive effect on Grade 3 Reading achievement, d = 0.48…

A theory-driven approach to evaluation (TDE) emphasizes the development and empirical testing of conceptual models to understand the processes and mechanisms through which programs achieve their intended goals. However, most reported applications of TDE are limited to large-scale experimental/quasi-experimental program evaluation designs. Very few…

During the past 50 years, wilderness and adventure programs have been utilized as a therapeutic intervention for adolescents involved in America's juvenile justice systems. The program that is the focus of this research project is the Wilderness Endeavors Program, a correctional wilderness and adventure program for youthful offenders in the state…

This study sought to determine the degree to which a body of successful supervision attributes actually exists in practice. Specifically, this investigation sought to determine: (1) To what extent are the twelve dimensions of supervisory practice from the 1989 ASCD Study currently being practiced among selected instructional leaders in two…

Null hypothesis significance testing alone is not sufficient for program evaluation. To assess program impact adequately, effect sizes should be reported and interpreted in the context of similar or alternate programs. A popular effect size for the treatment-control group design has been the standardized mean difference, delta. Several estimators…
