This study explores the direction and magnitude of racial disparities on three advanced placement (AP) computer science (CS) exams, namely AP CS Principles, AP CS A, and AP CS AB, based on the test scores of more than one million students who have taken AP CS exams between 1997 and 2020. Using Mann-Kendall test and Sen's slope procedures we found…

This paper examines learners' fluency development in L2 silent reading rate and comprehension. In both L1 and L2 readings, a positive relationship between readers' silent reading rate and comprehension has not been as firmly established as theories might propose. Based on Wallot et al. (2014), the paper indicates the need to look at readers'…

The COVID-19 pandemic has disrupted education around the world and created extraordinary new challenges for students, families, educators, and policymakers. Its impacts on students' learning and well-being are far reaching, though not yet fully understood. However, early evidence indicates disproportionate effects on students with disabilities, a…

Do teachers continue to improve in their effectiveness as they gain experience in the teaching profession? This paper aims to answer that question by critically reviewing recent literature that analyzes the effect of teaching experience on student outcomes in K-12 public schools in the United States. This report reviews 30 studies published within…

New Leaders is a nonprofit organization with a mission to ensure high academic achievement for all students by developing outstanding school leaders to serve in urban schools.

New Leaders is dedicated to promoting student achievement by developing outstanding school leaders to serve in urban schools. RAND Corporation researchers conducted a formative and summative external evaluation of the New Leaders program, its theory of action, and its implementation from 2006 through 2013. This document presents technical…

Almost all academic skills deficits can be conceptualized as learning rate problems as students are not failing to learn, but not learning rapidly enough. Thus, when selecting among various possible remedial procedures, educators need an evidence base that indicates which procedure results in the greatest increases in learning rates. Previous…

The nation is showing an unprecedented focus on increasing the rigor in education and preparing students for college. The college readiness trend is driving changes in the ways in which the nation uses student test data. Educational data are no longer limited to static data snapshots showing the status of a student performance at one point in…

In 2007, the Pittsburgh Public Schools (PPS) received funding from the U.S. Department of Education's Teacher Incentive Fund (TIF) program to implement the Pittsburgh Urban Leadership System for Excellence (PULSE), a set of reforms designed to improve the quality of school leadership throughout the district. A major component of PULSE is the…

This study employed hierarchical linear models (HLM) to investigate Peer-Led Guided Inquiry (PLGI), a teaching practice combining cooperative learning and inquiry and tailored for a large class. Ultimately, the study provided an example of the effective introduction of a reform pedagogical approach in a large class setting. In the narrative, the…

Community colleges play an important role in the U.S. economy, providing access to higher education for low-income young people, a path to higher-earning employment for low-income workers, and a supply of well-trained employees for local industry. In order to remain competitive with other major economies, however, the U.S. must sharply increase…

The Regional Educational Laboratory - Southwest (REL Southwest) conducted a systematic and comprehensive review of the research-based evidence on the effects of professional development (PD) on growth in student achievement in three core academic subjects (reading/ELA, mathematics, and science). The primary goal of this study was to address the…

Tennessee's Project STAR, a randomized experiment involving almost 12,000 pupils, demonstrated convincingly that small classes in the early elementary (K-3) grades increase pupil performance, reduce the test-score achievement gap between or among different social groups, and can have long-lasting effects. The benefits are greater for minority…

The purpose of this study was to determine the relationship between treatment-induced changes in academic achievement and social skills in elementary school-age children with attention-deficit hyperactivity disorder. A sample of 123 children in grades 1 through 4 with symptoms of inattention, impulsivity and/or hyperactivity, and significant…

To explore whether different balances of fiction/non-fiction reading and challenge might help explain differences in reading achievement between genders, data on 45,670 pupils who independently read over 3 million books were analysed. Moderate (rather than high or low) levels of challenge were positively associated with achievement gain, but…
