Improving argumentative writing and argumentative knowledge of English Language Learners and non-English Language Learners through dialogic instruction
Although rudimentary forms of argumentation emerge early in oral language, many students, especially English Language Learners (ELLs), struggle to construct evidence-based written arguments. These difficulties may stem from limited academic vocabulary, unfamiliarity with genre conventions, and fewer opportunities to use academic language involving argumentation. This study examined whether exposure to a dialogic instruction intervention that incl…
Impact of Automated Writing Evaluation (AWE) on Middle School Students’ Writing Outcomes
This study used a randomized, controlled trial to assess the impact of the automated writing evaluation system MI Write on middle school students from traditionally underserved groups, including Black and Hispanic/Latinx students and those experiencing poverty. The research focused on whether students who used MI Write for one school year (n = 1,260) showed improved argumentative writing performance, increased self-efficacy, greater enjoyment of …
The challenges of writing from sources in college developmental courses
This project includes the data and the analysis materials for the manuscript entitled "The Challenges of Writing from Sources in College Developmental Courses: Self-Regulated Strategy Instruction," which is in press at Journal of Educational Psychology
Bringing Assessment-to-Instruction (A2i) technology to scale
Bringing effective, research-based literacy interventions into the classroom is challenging, especially given the cultural and linguistic diversity of today's classrooms. We examined the promise of Assessment-to-Instruction (A2i) technology redesigned to be used at scale to support teachers' implementation of the individualized student instruction (ISI) intervention from kindergarten through third grade. In seven randomized controlled trials, A2i…

Understanding Impacts of SNAP Fruit and Vegetable Incentive Program at Farmers’ Markets
Disparities in healthy food access and consumption are a major public health concern. This study reports the findings from a two-year randomized control trial conducted at 77 farmers' markets (FMs) in 13 states and the District of Columbia that sought to understand the impact of fruit and vegetable (FV) incentive vouchers, randomly issued at varied incentive levels to Supplemental Nutrition Assistance Program (SNAP) recipients, for use at FMs. Me…
Recruitment, employment, retention and the minority teacher shortage
This study examines and compares the recruitment, employment, and retention of minority and nonminority school teachers over the quarter century from the late 1980s to 2013. Our objective is to empirically ground the ongoing debate regarding minority teacher shortages and changes in the minority teaching force. The data we analyze are from the National Center for Education Statistics’ nationally representative Schools and Staffing Survey (SASS) a…
Rethinking Connections Between Research and Practice in Education
Recent efforts to improve the quality and availability of scientific research in education, coupled with increased expectations for the use of research in practice, demand new ways of thinking about connections between research and practice. The conceptual framework presented in this paper argues that increasing research in educational decision-making cannot be simplified to an issue of dissemination or of motivating practitioners to access evide…
Year One Results From the Multisite Randomized Evaluation of the i3 Scale-Up of Reading Recovery
Reading Recovery (RR) is a short-term, one-to-one intervention designed to help the lowest achieving readers in first grade. This article presents first-year results from the multisite randomized controlled trial (RCT) and implementation study under the $55 million Investing in Innovation (i3) Scale-Up Project. For the 2011–2012 school year, the estimated standardized effect of RR on students’ Iowa Tests of Basic Skills (ITBS) Total Reading Score…
The Magnitude, Destinations, and Determinants of Mathematics and Science Teacher Turnover
This study examines the magnitude, destinations, and determinants of mathematics and science teacher turnover. The data are from the nationally representative Schools and Staffing Survey and the Teacher Follow-Up Survey. Over the past two decades, rates of mathematics and science teacher turnover have increased but, contrary to conventional wisdom, have not been consistently different than those of other teachers. Also, contrary to conventional w…
Recruitment, Retention, and the Minority Teacher Shortage
Established in 1985, CPRE unites researchers from seven of the nation's leading research institutions in efforts to improve elementary and secondary education through practical research on policy, finance, school reform, and school governance. CPRE studies alternative approaches to education reform to determine how state and local policies can promote student learning.
How Principals and Peers Influence Teaching and Learning
This paper examines the effects of principal leadership and peer teacher influence on teachers’ instructional practice and student learning. Using teacher survey and student achievement data from a mid-sized urban southeastern school district in the United States in 2006-2007, the study employs multilevel structural equation modeling to examine the structural relationships between student learning and theorized dimensions of principal leadership,…
Establishing Causality Using Longitudinal Hierarchical Linear Modeling
The predictive validity of personality for important life outcomes is well established, but conventional longitudinal analyses cannot rule out the possibility that unmeasured third-variable confounds fully account for the observed relationships. Longitudinal hierarchical linear models (HLM) with time-varying covariates allow each subject to serve as his or her own control, thus eliminating between-individual confounds. HLM also allow the directio…

Making Statistics More Meaningful for Policy Research and Program Evaluation
This article focuses on the use of statistics in policy and evaluation research and the need to present statistical information in a form that is meaningful to mixed audiences. Three guidelines for formulating and presenting meaningful statistics are outlined. Understandability ensures that knowledge of statistical methods is not required for comprehending the information presented. Interpretability ensures that statistical information can be exp…
Estimating the Effects of Interventions That are Deployed in Many Places
Place-randomized trials have been mounted in a variety of countries to estimate the relative effects of interventions that are intended to ameliorate problems or improve conditions in organizations and geopolitical jurisdictions. This article presents studies in which villages, police hot spots, housing developments, hospital units, schools, and other entities are the units of random allocation. The challenges to such work, approaches to meeting …
