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…

The project, "Oxford Improving Numeracy and Literacy Programme," was delivered by Oxford University Department of Education. This evaluation tested two different initiatives with Year 2 children: "Mathematics and Reasoning" and "Literacy and Morphemes." The "Mathematics and Reasoning" programme aimed to…

Speaking proceeds under the constraint of time. While speaking, speakers are under constant pressure to follow the message being received and to formulate rapid responses to their partners. In the IELTS (International English Language Testing System) Speaking Test, the communicative nature of the interview creates an ideal situation for applicants…

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…

Paired Reading is a peer tutoring programme in secondary schools which trains teachers to support and encourage the regular tutoring of Year 7 pupils (aged 11-12 years) by Year 9 pupils (aged 13-14 years). The Paired Reading programme aims to improve pupils' general literacy in addition to speaking and listening skills. This is achieved by pupils…

In this evaluation, as in previous years, four main aspects of the implementation of the West Virginia Board of Education's Master Plan for Statewide Professional Development were examined: (a) basic information reported by providers about the size and scope of the effort, including attendance, and adherence to the newly adopted standards for…

In spring 2010, Houghton Mifflin Harcourt (HMH) began planning a pilot of an application for the Apple iPad, "HMH Fuse: Algebra 1," which was then in development. The application was to be piloted in four California school districts during the 2010-2011 school year. HMH contracted with Empirical Education Inc. to conduct a one-year…

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…

This paper examines how controlling statistically for baseline covariates (especially pretests) improves the precision of studies that randomize schools to measure the impacts of educational interventions on student achievement. Part I of the paper introduces the concepts, issues, and options involved. Parts II and III present empirical findings…

This study investigated whether the software Virtus WalkThrough Pro could be used to enhance middle school children's spatial ability as measured by the Paper Folding, Mental Rotations, and Eliot-Price Tests. The study also investigated whether the use of this software impacted males differently than females, or users with high spatial ability…

This report describes the midterm and final tests administered to pupils in the Quality Assurance classes using the Learning Mastery System (LMS). Results are reported separately for both the Bank Street and Harper & Row versions of LMS. Means, standard deviations, and frequency distributions are given for the subscores and total for each test…
