Since 2004, the National Institute for School Leadership (NISL) has offered the Executive Development Program (EDP), a leadership program for sitting school principals that is typically delivered in two-day workshops once per month over 12 months. From its inception through 2018, 15,000 principals across 23 states have participated in the EDP.…

The contributions of assistant principals (APs) toward improving student and staff outcomes has not yet been a focus of much empirical research. In recent years, as the increased focus on improving student outcomes has shifted expectations and APs are now expected to perform some instructional leadership tasks, such as coaching and evaluating…

The purpose of this study was to determine the impact of the professional development training provided by the National Institute for School Leadership (NISL) on leadership behavior in schools. In order to achieve this overall objective, the following research questions framed this mixed methods study: 1. To what degree did the National Institute…

Research Findings: Children's (n = 980) social competence during prekindergarten was assessed as a function of their teachers' (n = 233) exposure to the Preschool Promoting Alternative Thinking Strategies (PATHS) curriculum and 2 levels of support through MyTeachingPartner, a Web-based approach to professional development. Children in classrooms…

Although paraprofessionals have become an increasingly integral part of special education services, most paraprofessionals lack training in evidence-based instructional strategies. We used a randomized contolled experimental design to examine the efficacy of a professional development training package and its individual components to equip 25…

Research Findings: Big Math for Little Kids (BMLK) is a mathematics curriculum developed for use with 4- and 5-year-old children. To investigate the BMLK curriculum's effect on children's mathematics knowledge, this cluster-randomized controlled trial randomly assigned child care centers to provide mathematics instruction to children, using either…

The purpose of this study was to examine the effects on four-year-olds' knowledge of mathematics by introducing professional development and center-based mathematics activities around four mathematical domains to early educators' teaching in Head Start programs. Because of the need to provide necessary mathematical experiences to young children to…

This study examined the characteristics of 10 science, technology, engineering and mathematics (STEM) focused high schools that were selected from various regions across the United States. In an effort to better prepare students for careers in STEM fields, many schools have been designed and are currently operational, while even more are in the…

This article describes a study examining the effects of Sheltered Instruction Observation Protocol (SIOP) model instruction on the academic language performance of middle and high school English language learners. The SIOP model is an approach for teaching content curriculum to students learning through a new language. Teachers employ techniques…

The authors present three studies (two randomized controlled experiments and one embedded quasi-experiment) designed to evaluate the impact of replacement units targeting student learning of advanced middle school mathematics. The studies evaluated the SimCalc approach, which integrates an interactive representational technology, paper curriculum,…

The goal of this study was to test the effectiveness of WestEd's Reading Apprenticeship (RA) professional development program on teacher practices and student learning. The professional development is designed to teach high school teachers how to integrate subject-specific literacy instruction into their regular curricula. The CRESST researchers…

This report describes a classroom artifact measure and presents early findings from an efficacy study of WestEd's Reading Apprenticeship (RA) professional development program. The professional development is designed to teach high school teachers how to integrate subject-specific literacy instruction into their regular curricula. The current RA…

This article reports on the first 4 years of an effort to develop comprehensive and sustainable mathematics education reforms in high poverty middle schools. In four related analyses, we examine the levels of implementation achieved and impact of the reforms on various measures of achievement in the first 3 schools to implement the Talent…

Considerable effort has been made over the past decade to address the needs of learners in large urban districts through scaleable reform initiatives. We examine the effects of a multifaceted scaling reform that focuses on supporting standards based science teaching in urban middle schools. The effort was one component of a systemic reform effort…

This study used a randomized field trial design to evaluate the efficacy of a research-based model for scaling up an intervention focused on preschool mathematics. Although the successes of research-based educational practices have been documented, equally well known is the paucity of successful efforts to bring these practices to scale. The same…
