Despite alarming rates and negative consequences associated with urban teacher attrition, mentoring programs often fail to target the strongest predictors of attrition: "effectiveness" around classroom management and engaging learners; and "connectedness" to colleagues. Using a mixed-method iterative development framework, we…

Advances in statistics provide new methods for analyzing practice data. These advances include person-centered methods (PCMs) that identify subgroups of research participants with similar characteristics. PCMs derive from a frame of reference that is similar to the risk factor perspective in practice. In practice, the delivery of services is often…

At least some of the challenges faced in special education, such as the disproportionate representation of culturally and linguistically diverse students, the gap between research and practice, and inequitable educational opportunities, can be explained in part by a research gap, or, in other words, a failure to conduct the different types of…

Young children who exhibit problem behavior are at-risk for a host of negative developmental outcomes. Early intervention at multiple ecological levels is crucial to interrupt what can be a detrimental transactional cycle between children and their caregivers, including their teachers. In this article we promote a strengths-based approach to…

This paper presents the results of a survey study to understand the differentiation of tuition and fee charges at postsecondary education institutions. The purpose of this study is to understand the extent to which postsecondary institutions set charges that differ depending on academic program, student status, residency, student service in the…

We investigated the relation between children's numerical-magnitude representations and their memory for numbers. Results of three experiments indicated that the more linear children's magnitude representations were, the more closely their memory of the numbers approximated the numbers presented. This relation was present for preschoolers and…

ASSISTments is a web-based math tutor designed to address the need for timely student assessment while simultaneously providing instruction, thereby avoiding lost instruction time that typically occurs during assessment. This article presents a quasi-experiment that evaluates whether ASSISTments use has an effect on improving middle school…

School-based prevention programs can positively impact a range of social, emotional, and behavioral outcomes. Yet the current climate of accountability pressures schools to restrict activities that are not perceived as part of the core curriculum. Building on models from public health and prevention science, we describe an integrated approach to…

In this article, we describe and report on the results of a study in Texas that tested 2 models of professional development for classroom teachers as a way of improving their practices and increasing the reading achievement of their students. To meet this goal, 44 participating teachers in grades 2-8 learned to teach their students cognitive…

Learning in educational settings emphasizes declarative and procedural knowledge. Studies of expertise, however, point to other crucial components of learning, especially improvements produced by experience in the extraction of information: perceptual learning (PL). We suggest that such improvements characterize both simple sensory and complex…

This study examines the different processes that institutional researchers use to calculate the number of transfers-out for the Integrated Postsecondary Education Data System (IPEDS) Graduation Rate Survey (GRS), with a particular focus on how the process is influenced by institutional mission and data availability. Policy makers and the public…

As demand for information on postsecondary education has increased, institutions have had to adapt information systems to accurately report data. Institutions currently respond to multiple constituencies including national media outlets, higher education associations, state regulatory authorities, and federal agencies. The purpose of this study is…

Objective--Recent follow-along studies of personality disorders have shown significant improvement in psychopathology over time. The purpose of this study was to prospectively investigate the association between positive childhood experiences related to resiliency and remission from personality disorder. Method--Five hundred twenty patients with…

Learning in educational settings most often emphasizes declarative and procedural knowledge. Studies of expertise, however, point to other, equally important components of learning, especially improvements produced by experience in the extraction of information: "Perceptual learning." Here we describe research that combines principles of…

This project entailed a three-year efficacy evaluation of the Computer and Team Assisted Mathematical Acceleration (CATAMA) Lab developed by the Center for Social Organization of Schools at Johns Hopkins University. The CATAMA Lab was proposed as an immediate and practical approach to addressing the different types of math deficits held by…
