The effectiveness and program mechanisms of a whole-school anti-bullying program that builds on the socio-ecological framework were investigated by applying person-oriented methods of data analyses. A longitudinal cluster randomized control study was utilized comprising 1377 adolescents (48.5% girls, M[subscript age] = 11.7) who participated in a…

This dissertation examines the effect of a Buddhist-based program of mindfulness, taught as part of the curriculum of a graduate program, on the relationship of teacher-practitioners with their work. Collecting data on the experiences of three cohorts over a nearly three-year period, this longitudinal case study examines the experiences of…

The purpose of this study was to examine the effectiveness of Ears On, an intervention designed to increase toddlers' use of hearing devices. A single-case, multiple-baseline design across participants was used with three parent-child dyads who demonstrated low hearing aid use despite enrollment in traditional early intervention services. Data…

Programs that improve teaching effectiveness represent a core strategy to improve student educational outcomes and close student achievement gaps. This article compiles empirical values of intraclass correlations for designing effective and efficient experimental studies evaluating the effects of these programs. The Early Childhood Longitudinal…

In spite of the superior effects of semester- or year-long educational experiences abroad, the majority of students prefers short-term study abroad for which participation numbers are steadily rising. Due to the increased student interest in short-term study abroad options, investigations into how a short stay abroad can be designed to maximize…

The purpose of this study was to compare student growth of SCSD-7 students on the MAP (Measures of Academic Progress) reading assessment to otherwise similar students who did not use Istation. This study followed two cohorts of elementary school students over three years (2016-17 through 2018-19) to assess the effect of Istation on reading…

Background: The Student Assistance Program (SAP) is mandated kindergarten to 12th grade in Pennsylvania schools to address barriers to student academic success. Following student referral, SAP teams use a systematic process to inform recommendations for school or community-based services. To evaluate program outcomes, a review of student SAP…

This paper is the first to examine the longitudinal results of six years of implementation of Literacy Squared, a biliteracy model for Spanish/English speaking emerging bilingual students. This model includes paired literacy instruction with grade-specific time allocations for Spanish literacy and literacy-based ELD. Furthermore, cross-language…

In the United States, teacher preparation programs are under increased pressure to demonstrate their effectiveness in producing graduates with knowledge, abilities, and competencies to be quality teachers. However, very little research shows this kind of evidence. In a rare exception, Hiebert, Miller, and Berk (2017) found significant positive…

Given the history of poor postschool outcomes for students with disabilities, researchers repeatedly sought to demonstrate the links between predictor variables and postschool outcomes for students with disabilities. This secondary data analysis used the National Longitudinal Transition Study-2 to examine the relationship between postsecondary…

This program evaluation examines the effectiveness of a school-based dental clinic. A repeated-measures design was used to longitudinally examine secondary data from participants (N = 293). Encounter intensity was developed to normalize data. Multivariate analysis of variance and Kruskal-Wallis test were used to investigate the effect of encounter…

We utilized data from a multi-institutional longitudinal study to investigate the association between diversity-related coursework and moral development among students over 4 years of college. Our findings parallel the prior research, which support the positive effects of diversity on college students, by offering new evidence that diversity…

Background: Afterschool programs (ASPs) in the United States have been implemented in low income neighborhoods to enable at-risk youth to access educational support services to increase academic skills. However, mixed findings about the ASPs positively affecting academic performance suggests a need for additional evaluative studies. Objective: The…

Science, technology, engineering, and mathematics (STEM) skills are very valuable for economic growth. However, the number of young people pursuing STEM learning trajectories in the United Kingdom was lower than the predicted demand during the last decade. Several STEM enrichment and enhancement activities were thus funded by the government,…

This quasi-experimental study adds to the small existing literature on orthographic-related teacher knowledge in an English as a foreign language (EFL) context. The study examined the impact of a course on English orthography on predominantly non-native-speaking EFL preservice and inservice teachers' orthographic content knowledge, and the extent…
