Despite recommendations to extend prevention and early intervention related to behavioral health into school settings, limited research has been directed toward understanding how these recommendations have been translated by states into education policies and initiatives. This macro-level information is important toward understanding the…

Research from the past two decades positions relational trust as a key factor in school reform efforts. Trust between teachers and their principal (teacher-principal trust) and teachers and their colleagues (teacher-teacher trust) are particularly important. "Leading Together" (LT) is a new professional development and coaching model of…

This study of 8-16-year-olds was designed to test the hypothesis that reading comprehension impairments are part of the social communication phenotype for many higher-functioning students with autism spectrum disorder (HFASD). Students with HFASD (n = 81) were compared to those with high attention-deficit/hyperactivity disorder symptomatology…

Existing reviews answer important questions about subsets of practitioner training studies in special education, but leave important questions about the broader literature unanswered. In this comprehensive review, we identified 118 peer-reviewed single-case design studies in which researchers tested the efficacy of practitioner training on…

This paper presents evidence from a unique reform model that allowed teachers and other educators in a large urban district to collaborate with one another in the development of an innovation meant to improve student ownership and responsibility. In this longitudinal case study, we describe school stakeholders' learning about the design, the…

Item response models typically assume that the item characteristic (step) curves follow a logistic or normal cumulative distribution function, which are strictly monotone functions of person test ability. Such assumptions can be overly-restrictive for real item response data. We propose a simple and more flexible Bayesian nonparametric IRT model…

Hoping to spur dramatic school turnaround, the federal government channeled resources to the country's lowest-performing schools through School Improvement Grants (SIG). However, prior research on SIG effectiveness is limited and focuses primarily on student achievement. This study uses a difference-in-differences strategy to estimate program…

Energy is a critically important topic in the K-12 science curriculum, with many applications in the earth, physical, and life sciences and in engineering and technology. To meet the challenges associated with teaching energy, new tools and assessment instruments are needed. In this work we describe the development of a three-tier assessment…

Effectively educating the large English learner population requires policymakers to ensure developmentally appropriate settings and services throughout the time students are learning English, as well as during their transition to fluent English proficient status--a process termed reclassification. Using longitudinal student-level data from two…

Focusing on the science knowledge and pedagogical content knowledge that teachers need to realize the vision of the "Next Generation Science Standards" (NGSS) in their classrooms, this study presents findings from efforts to (1) adapt existing criteria and design heuristics for educative features of curriculum materials to the needs of…

This article is a follow-up to a previous Journal of Physical Education, Recreation, and Dance Viewpoint article ("The Physical Activity Movement and the Definition of Physical Education"), wherein the authors challenged the oft-cited distinction between physical education and physical activity, and proposed an alternate definition of…

Many children and adults have difficulty gaining a comprehensive understanding of rational numbers. Although fractions are taught before decimals and percentages in many countries, including the USA, a number of researchers have argued that decimals are easier to learn than fractions and therefore teaching them first might mitigate children's…

K-12 education standards in the U.S. require all students to read complex texts across many subject areas. The "Language Muse™ Activity Palette" is a web-based language-instruction application that uses NLP algorithms and lexical resources to automatically generate language activities and support English language learners' content…

There is a priority for schools to address students' social and emotional needs as we do academic learning. Tiered models of prevention provide a framework for teaching social skills and behavioral expectations, as well as academics, with positive, proactive, evidence-based practices. Central to responding to students' needs is accurate…

In this paper we examine how failing to make adequate yearly progress under No Child Left Behind (NCLB), and the accountability pressure that ensues, affects various non-achievement student behaviors. Using administrative data from North Carolina and leveraging a discontinuity in the determination of school failure, we examine the causal impact of…
