Evidence that teachers' short-term instructional effects persist over time and predict substantial long-run impacts on students' lives provides much of the impetus for a wide range of educational reforms focused on identifying and responding to differences in teachers' value-added to student learning. However, relatively little research has…

This evaluation study provides information about the implementation and outcomes of the 21st Century Community Learning Centers (21st CCLC) program in West Virginia, from September 2015 through May 2016, in which 12,388 students participated overall. The report draws on information from online surveys of directors of thirty six 21st CCLC programs…

Conceptualizations of developmental trends are driven by the particular method used to analyze the period of change of interest. Various techniques exist to analyze developmental data, including individual growth curve analysis in observed and latent frameworks, cross-lagged regression to assess interrelations among variables, and multilevel…

Class size reduction has been viewed as one school mechanism that can improve student achievement. Nonetheless, the literature has reported mixed findings about class size effects. We used 4th- and 8th-grade data from TIMSS 2003 and 2007 to examine the association between class size and mathematics achievement in public schools in Cyprus. We…

Out-of-school factors can significantly impact students' readiness to learn and thrive in school. Research confirms that larger social structures and contexts beyond the school are critical, accounting for up to two-thirds of the variance in student achievement (Coleman et al., 1966; Rothstein, 2010; Phillips, Brooks-Gunn, Duncan, Klebanov, &…

During the 2015-2016 academic year, the parents of 4,974 students participated in APTT [Academic Parent Teacher Teams] at 10 Title 1 elementary schools in the Houston Independent School District (HISD). Students were predominately economically disadvantaged and at risk of dropping out of school. The impact of the program was assessed using the…

This study explores preliminary results from a pedagogical intervention designed to improve instruction for all students, particularly emergent bilinguals in the United States (or English language learners). The study is part of a larger efficacy randomized controlled trial (RCT) of the Instructional Conversation (IC) pedagogy for improving the…

To evaluate the influence of scientifically based curricula intended for the physical education (PE) classroom, researchers should consider fidelity, or the extent to which teachers who are implementing a PE curricular intervention adhere to the model of curriculum and instruction inherent in the research design. The purpose of this study was to…

The effect of student mobility on student outcomes has garnered much attention by researchers and policy-makers over the past few decades. The extant research relies on annual tests, typically measured each spring, to estimate the effect of structural moves on student achievement. The current literature does not allow researchers to evaluate…

We use a regression-discontinuity design to study the effects of double blocking sixth-grade students in reading and mathematics on their achievement across three years of middle school. To identify the effect of the intervention, we use sharp cutoffs in the test scores used to assign students to double blocking. We find large, positive, and…

This study compares Singaporean Grade 6 students' performance and strategy preference on two graphic-rich mathematics tasks, presented via pencil-and-paper and iPad modes. There were statistically significant differences between students' performances on the two tasks, one in favour of the paper mode and the other in favour of the iPad. Students…

Schools are positioned to play a key role in nurturing students with knowledge and behaviours associated with healthful living. Our study examined the effects of an intervention on energy balance (EB) knowledge. Twelve 6th and 7th grade classrooms (n = 140) were assigned to receive either two standardised lessons on EB or a combined intervention…

Researchers and practitioners alike have noted that Hmong students in the United States do not achieve as well as their monolingual peers and other bilingual students. The current mixed-methods study is designed to describe reading development and achievement of 4th-grade Hmong students in one large, urban school district. This study explores the…

This study evaluates the impacts and costs of the Reading Partners program, which uses community volunteers to provide one-on-one tutoring to struggling readers in under-resourced elementary schools. The evaluation uses an experimental design. Students were randomly assigned within 19 different Reading Partners sites to a program or control…

Students of color are underrepresented in gifted programs relative to White students, but the reasons for this underrepresentation are poorly understood. We investigate the predictors of gifted assignment using nationally representative, longitudinal data on elementary students. We document that even among students with high standardized test…
