The purpose of this longitudinal study is to investigate whether an early childhood intervention using an explicit and transparent number naming system will have a lasting benefit to English and Spanish speaking children in their mathematics achievement related to number sense by accelerating their acquisition of concepts of numeracy and place…

Development of fraction number line estimation was assessed longitudinally over 5 time points between 4th and 6th grades. Although students showed positive linear growth overall, latent class growth analyses revealed 3 distinct growth trajectory classes: Students who were highly accurate from the start and became even more accurate (n = 154);…

The purpose of this closely aligned conceptual replication study was to investigate the efficacy of a Tier 2 kindergarten mathematics intervention. The replication study differed from the initial randomized controlled trial on three important elements: geographical region, timing of the intervention, and instructional context of the…

Today's classroom is the continuation of America as "the melting pot". Within this educational setting is an increased emphasis on student mathematical success as well as the acquisition of the English language by foreign-born students, whose families have come as an actualization of the American dream. Educators are striving to find…

Development of fraction number line estimation was assessed longitudinally over five time points between fourth and sixth grades. Although students showed positive linear growth overall, latent class growth analyses revealed three distinct growth trajectory classes: Students who were highly accurate from the start and became even more accurate (n…

Using administrative longitudinal data from five states, we study how value-added measures of teacher performance are affected by changes in state standards and assessments. We first document the stability of teachers' value-added rankings during transitions to new standard and assessment regimes and compare our findings to stability during stable…

This review summarizes virtually all available evidence on the effectiveness of specific afterschool programs, based on a comprehensive literature search and review of studies published in 2000 or later. The review is motivated, in part, by a growing emphasis on using rigorous assessment of program impacts to inform decision-making in education…

In explaining academic achievement, school climate and social belonging (connectedness, identification) emerge as important variables. However, both constructs are rarely explored in one model. In the current study, a social psychological framework based on the social identity perspective (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987) is…

Since the mid '70s, school districts have been trying to place students with disabilities in the least restricted environment. As governments strive to create a more inclusive society, an inclusive academic setting for students with disabilities has become a priority. The purpose of the study was to examine the impact of academic setting on…

School district-university research collaborations represent one strategy to increase educators' ability to use current, research-based information in program decision-making and efforts to improve student achievement. However, differences in organizational structures, goals, values, and prior collaborative experiences, have made successful…

The effect of an acute bout of physical activity on academic performance in school-based settings is under researched. The purpose of this study was to examine associations between a single, vigorous (70-85%) bout of physical activity completed during physical education on standardized mathematics test performance among 72, eighth grade students…

We analyze the diminishing correlations between education expenditure and learning outcomes to address two fundamental questions: Do education systems with different levels of education spending have different student achievement levels? If so, at what amount of education spending does the relationship between increased expenditure and student…

A typically developing student's perceptions of his or her own capabilities (academic self-concept), is predictive of later academic achievement. However, little is known about academic self-concept in youth with autism spectrum disorder (ASD). To understand whether students math self-concept and reading self-concept predicted their performance,…

Since 2002 the federal government has required states to have accountability systems that measure the quality of schools. When the No Child Left Behind (NCLB) Act ushered in the accountability era nationwide, it did so with the ambitious goal of ensuring that by 2014 "all children . . . reach, at a minimum, proficiency on challenging state…

Middle school math placement and progression are topics that are part of an active policy and practice discussion in California and elsewhere. Beginning in the 2008/09 school year, California's State Board of Education recommended that students complete algebra I by the end of grade 8. Between 2003 and 2009 the proportion of grade 8 students…
