As a result of the No Child Left Behind Act (NCLB) of 2001, many school districts have reduced instructional time for the arts in order to focus on reading and mathematics. Accordingly, fine arts programs across the nation have become subject to budget cuts or elimination in order to meet federal accountability measures. Hit especially hard are…

The capacity of the field to conduct power analyses for group randomized trials (GRTs) of educational interventions has improved over the past decade (Authors, 2009). However, a power analysis depends on estimates of design parameters. Hence it is critical to build the empirical base of design parameters for GRTs across a variety of outcomes and…

In this paper, we examine the validity and precision of two nonexperimental study designs (NXDs) that can be used in educational evaluation: the comparative interrupted time series (CITS) design and the difference-in-difference (DD) design. In a CITS design, program impacts are evaluated by looking at whether the treatment group deviates from its…

How well are our nation's high schools preparing students for college and career? Recent analyses by ACT show low rates of college and career readiness among United States high school graduates. Data from postsecondary institutions reveal high remediation rates and low second-year retention rates among first-year college students. Employers lament…

The POWERSOURCE[c] intervention is intended as a generalizable and powerful formative assessment strategy that can be integrated with any mathematics curriculum. POWERSOURCE[c] includes both a system of learning-based assessments and an infrastructure to support teachers' use of those assessments to improve student learning. The core undertaking…

In 2009-10, 92% of WCPSS schools met Expected or High Growth as measured by the North Carolina ABCs program, a 3.5 percentage point increase from 2008-09. Fifty-four percent of the schools made High Growth and 38% made Expected Growth. All subgroups saw their percentages of students meeting growth increase to above 55% in 2009-10; with the…

This paper uses data from the Head Start Impact Study (HSIS), a nationally representative multisite randomized trial, to quantify variation in effects of Head Start during 2002-2003 on children's cognitive and socio-emotional outcomes relative to the effects of other local alternatives, including parent care. We find that (1) treatment and control…

Due to their motivational nature, there has been growing interest in the potential of games to help teach academic content and skills. This report examines how different levels of detail about a game's scoring rules affect math learning and performance. Data were collected from 164 students in the fourth to sixth grades at five after-school…

Collaborative Strategic Reading (CSR) is a set of instructional strategies designed to improve the reading comprehension of students with diverse abilities (Klingner and Vaughn 1996). Teachers implement CSR at the classroom level using scaffolded instruction to guide students in the independent use of four comprehension strategies; students apply…

Understanding the meaning of rational numbers and how to perform mathematical operations with those numbers seems to be a perennial problem in the United States for both adults and children. Based on previous work, we hypothesized that giving students more time to practice using rational numbers in an environment that enticed them to apply their…

This report describes results from field-testing of POWERSOURCE[C] formative assessment alongside professional development and instructional resources. The researchers at the National Center for Research, on Evaluation, Standards, & Student Testing (CRESST) employed a randomized, controlled design to address the following question: Does the…

Results after two years of using three reading comprehension curricula show gains from one program and no effects for the other two on reading comprehension for fifth-graders, according to a study released by the National Center for Education Evaluation and Regional Assistance in the Institute of Education Sciences. The study focused on whether…

Through the Section 41, State Bilingual Education program and the E.C.I.A. Chapter 1, Migrant Education program, Saginaw public schools provide supplemental instruction and specialized services in 24 elementary and 6 secondary schools. In 1990-91, the bilingual program served 773 students, mostly Hispanic and some Laotian, while the migrant…

The Maui Hawaii Educational consortium (the Maui School District and Maui Community College) sought scientifically based evidence for the effectiveness of the "Cognitive Tutor (CT) Algebra I Curriculum" to inform adoption decisions. Decision makers were particularly interested in whether the use of the "CT" program affects…

An integral part of Title I of the Elementary and Secondary Education Act programs has been the evaluation of these programs in terms of attainment of increments of gain in reading and mathematics. One of the most widely used methods of analyzing pre and post test norm referenced data has been the six-step historical regression procedure. This…
