The problem in this study was that despite encouragement from administrators, kindergarten through Grade 8 teachers struggled to use project-based learning (PBL) in a local school in the Association of Independent Maryland and DC Schools (AIMS). Rooted in Kilpatrick's progressive philosophy of education and Piaget's theory of constructivism, this…

The 2007 Public Education Reform Amendment Act led to 39 percent of the principals in District of Columbia Public Schools (DCPS) being dismissed before the start of the 2008-09 school year, and additional principal exits over the next few years. We measure the impact of replacing these principals on schoolwide student achievement by measuring the…

Over the past 30 years, numerous policies have focused on closing the achievement gap in the United States. Despite this emphasis on mastery and proficiency, students continue to perform below expectations. We use standardized math test performance to explore whether schools have been able to eliminate the achievement gap across middle-level…

Too many talented students who go to under-resourced schools do not achieve their full potential. Though they may perform very well relative to their classmates, these students do not receive the same kinds of academically challenging opportunities throughout their educational journey as do their counterparts in better-resourced public and private…

In this article, we present analyses from a researcher-practitioner partnership in the District of Columbia Public Schools, where we are exploring the impact of educational software on students' academic achievement. We analyze a unique data set that combines student-level information from the district with data of student usage of a mathematics…

Researchers often presume that it is better to use administrative data from grades 4 and 5 than data from grades 6 through 8 for conducting research on teacher effectiveness that uses value-added models because (1) elementary school teachers teach all subjects to their students in self-contained classrooms and (2) classrooms are more homogenous at…

In this paper, we present a closer look at the student achievement trends in the District of Columbia between 2006-07 and 2012-13. We have three main conclusions. First, we find that overall, math scores in the District have improved. The improvements in reading scores during this time frame, however, were primarily limited to the first year after…

Individual differences in trajectories of anxious withdrawal were examined from Grades 5 to 8 across the transition to middle school in a community sample (N = 283), using General Growth Mixture Modeling. Three distinct pathways of anxious withdrawal were identified: "low-stable" (78%), "high-decreasing" (12%), and…

This study describes English language learner (ELL) student enrollment trends between 2002/03 and 2008/09 and achievement trends between 2006/07 and 2008/09 in the District of Columbia. Two research questions guide this study: (1) How did the enrollment of ELL students in District of Columbia public schools change between 2002/03 and 2008/09?; and…

The purpose of this article is to outline the process, content, and evaluation of a 14-week health education program for 6th, 7th, and 8th grade students in an inner city Catholic grade school who are at risk for multiple health problems. The process includes a needs assessment with findings, followed by construction of an age-appropriate program.…

DC Public Schools has adopted new learning standards for core subjects, including reading/English language arts, mathematics, science, and social studies. The new standards show what students should know and be able to do: (1) in each subject; (2) at each grade level; and (3) in every school. Standards tell all students that they are expected to…
