In experimental evaluations of health and social programs, the role of dosage is rarely explored because researchers cannot usually randomize individuals to experience varying dosage levels. Instead, such evaluations reveal the average effects of exposure to an intervention, although program exposure may vary widely. This article compares three…

It is a matter of concern when large, federally funded programs are evaluated using designs that produce misleading information. In this article, we discuss problems associated with an evaluation design that was adopted by the U.S. Department of Education, Office of Special Education Programs (OSEP) to document the performance of a major early…

Against the background of a European-wide strategy of governance aimed at improving support for parents and families, the following report details the conceptualization and evaluation of a federal state program in Baden-Württemberg (Germany) which was launched in 2008 to encourage family and parent education. Two program components, a voucher…

Preschool parent interventions may produce downstream benefits if initial intervention gains are sustained and improve later socialization experiences. This study explored associations between initial effects of the REDI (Research-based Developmentally Informed) Parent program and later benefits. A randomized trial involving 200 Head Start…

We provide an overview of research in sustainability education. We argue that the interconnectedness of environmental sustainability programs at K-12 schools is one metric by which sustainability education can be conceptualized. We present a new measure of whole-school sustainability, or "interconnectedness," and then use it to compare…

Notwithstanding broad utility of COPs (classroom observation protocols), there has been limited documentation of the psychometric properties of even the most popular COPs. This study attempted to fill this void by closely examining the item and domain-level IRR (inter-rater reliability) of a COP that was used in a federally funded striving readers…

Delaware was in the first group of states to receive a federal grant in 2012 to improve early care and education services and increase the number of infants, toddlers, and preschool-age children in high-quality programs. One component of the state's grant is a rigorous validation process for Delaware Stars for Early Success, a voluntary quality…

Correlational analysis of two years of classroom observation indicates relationships between technology use and various classroom characteristics, including teacher roles and instructional strategies. Three observers used the ISTE Classroom Observation Tool (ICOT) to record 144 observations of classrooms participating in a variety of educational…

The purposes of this study were to evaluate a federal and state-funded Family Caregiver Support Program (FCSP) and explore what types of caregiver support service are associated with what caregiver outcomes. Information was obtained on a sample of 164 caregivers' use of eleven different types of support service. Descriptive and comparative…

This article examines the power analyses for the first wave of group-randomized trials funded by the Institute of Education Sciences. Specifically, it assesses the precision and technical accuracy of the studies. The authors identified the appropriate experimental design and estimated the minimum detectable standardized effect size (MDES) for each…

The "No Child Left Behind Act of 2001" (PL 107-110) established the Reading First (RF) Program (Title I, Part B, Subpart 1), a major Federal initiative designed to help ensure that all children can read at or above grade level by the end of third-grade. The legislation (Section 1205 of the Elementary and Secondary Education Act) requires…
