Four types of analysis are commonly applied to data from structured Rater [times] Ratee designs. These types are characterized by the unit of analysis, which is either raters or ratees, and by the design used, which is either between-units or within-unit design. The 4 types of analysis are quite different, and therefore they give rise to effect…

Many have elaborated on the potential of virtual reality (VR) in learning. This article attempts at organizing the literature in this issue in order to better identify indicators that can account for future valid trends, and seeks to bring to attention how authors who wrote about the future of VR in education confused futures' terms and produced…

The 2001 renewal of the United States' Title I program, which provides federal funds to schools with large populations of low-income students, instituted the Supplemental Educational Services (SES) program in which schools in their third year of failing to make Adequate Yearly Progress (AYP) are required to offer after-school tutoring in core…

Meta-analysis was applied to study the empirical research from 1990-2007 regarding the effectiveness of the dating violence prevention programs in middle and high schools on students' knowledge and attitudes. The results show that overall the program participants improved their knowledge and attitudes towards dating violence. Implications for…

Including English language learners (ELLs) in large-scale assessments raises questions about the validity of inferences based on their scores. Test accommodations for ELLs are intended to reduce the impact of limited English proficiency on the assessment of the target construct, most often mathematic or science proficiency. This meta-analysis…

This study examined the percentage of task-sampling variability in performance assessment via a meta-analysis. In total, 50 studies containing 130 independent data sets were analyzed. Overall results indicate that the percentage of variance for (a) differential difficulty of task was roughly 12% and (b) examinee's differential performance of the…

This article describes how one university-based center, UCLA's Center X, has worked to prepare and sustain urban educators over the past 16 years. Synthesizing findings from more than 20 articles, papers, books, and dissertations that report on Center X's work, we argue that three key activities are necessary to spur change and ensure a…

The relationship between functional or life skills curricula (the intervention) and transition-related outcomes for secondary-aged youth with disabilities is explored in this systematic review. A total of 50 studies intervening with 482 youth with (largely) disability labels of moderate to severe mental retardation were reviewed. The findings of…

While e-learning, Web-enhanced instruction, and other forms of instructional technology have been touted as an effective way of addressing student withdrawal and academic performance, there are those (Carr, 2000) that report both program and end-of-semester course completion rates in distance education courses as merely acceptable compared to more…

This "Research Update" explores two major themes: (1) Using evaluation to shape program improvement and planning; and (2) Out-of-school time benefits to older youth and their families. Themes were culled from 13 research and evaluation reports added to the Out-of-School Time (OST) Program Research and Evaluation Bibliography in September 2008.…

This paper synthesizes conceptual and empirical literature on organizational learning interventions based on dialogue. First, I attempt to delineate the concept of dialogue and to explain its relevance to organizational learning. Examples and arguments in support of dialogic learning initiatives are presented. Organizational realities and…

Gerontologic research in the past 40 years has shown that caring for an older, disabled person affects the health and well-being of the caregiver. This important contribution led to a wide range of programs and services designed to buffer caregivers from the effects of stressors. Many of these programs have been quite innovative. Although…

In our attempts to track changes in geological practice over time and to isolate the source of these changes, we have found that they are largely connected with the germination of new geologic subdisciplines. We use keyword and title data from articles in 68 geology journals to track the changes in influence of each subdiscipline on geology over…

Although some theories suggest that anxious individuals selectively remember threatening stimuli, findings remain contradictory despite a considerable amount of research. A quantitative integration of 165 studies with 9,046 participants (clinical and nonclinical samples) examined whether a memory bias exists and which moderator variables influence…

In this article we identify the key survey data for examining the issue of equality in the lives of disabled people in the UK. Such data is essential for assessing change in quality of life over time and for the evaluation of the impact of policy initiatives. For each data source we consider definitions, data collection, issue coverage, sample…
