Studies focusing on the effectiveness of computer-assisted instruction have been growing recently in Turkey. In this research, quantitative studies comparing the effectiveness of computer-assisted instruction to traditional teaching method and conducted between 1998 and 2007 are studied by meta analysis. Seventy eight studies that have eligible…

Despite having drawn from empirical evidence and cumulative prior expertise in the formulation of research questions as well as study design, each study is treated as a stand-alone product rather than positioned within a sequence of cumulative evidence. While results of prior studies are typically cited within the body of prior literature review,…

"Project Read"[R] is a multisensory language arts curriculum designed for use in a classroom or group setting. Two main objectives of the program are to use language in all its forms, and to use responsive instruction rather than preplanned textbook lessons. The program emphasizes direct instruction, and lessons move from letter-sounds…

The CATO Institute's Policy Analysis "They Spend WHAT? The Real Cost of Public Schools" contends that the figures most commonly associated with spending on K-12 public education do not include all relevant expenditures. It also cites survey evidence suggesting that voters underestimate the cost of education and, when presented with a higher…

This report describes the findings of an analysis of a series of action research projects conducted by Vigo County School Corporation at Terre Haute North Vigo High School. During the 2009-2010 school year, 17 teachers participated in independent action research studies regarding the extent to which selected instructional strategies enhanced the…

The aim of this review was to examine the literature on the effects of surgery of the spastic hand in children with cerebral palsy on functional outcome and muscle coordination. We performed a search of the relevant literature in Medline, Embase, and Biological Abstracts from 1966 to June 2006. The search resulted in eight studies on the effect of…

Background: Burnout has been highlighted as a significant problem for workers in the intellectual disabilities field. A growing number of studies have investigated the levels of burnout and its correlates amongst this population, although they have often reported somewhat contradictory findings. Materials and methods: The present paper sought to…

As scholars and their audiences pursue standards of evidence, standards for literature reviews have also become salient. Many authors advocate "systematic" reviews and articulate standards for these. This article compares the bodies of literature derived from systematic and other types of review, which the author labels conceptual, and…

Three drug and alcohol use screening scales are embedded within the Minnesota Multiphasic Personality Inventory--2: the MacAndrew Alcoholism Scale (MAC) and its revised version (MAC-R), the Addiction Acknowledgement Scale (AAS), and the Addiction Potential Scale (APS). The current study evaluated the reliability reporting practices among 210…

Context: Although there have been substantial advances in knowledge about drug prevention over the last decade, the majority of school-based drug prevention studies have been conducted in urban settings. There is little knowledge about the effectiveness of such programs when they are implemented in rural populations. Purpose: To examine the…

Meta-analysis is a useful tool for empirically reviewing large bodies of research. It assures that lecture materials are comprehensive and that highlighted studies are supported by a body of knowledge. Many educators are not familiar with the range of topics that has been empirically summarized using meta-analytic techniques. To fill this void, a…

Using meta-analytic techniques, results were synthesized from 58 empirical sources on the association between being married and subjective well-being (SWB). Results indicated that being married was positively and significnatly associated with SWB. However, the magnitude of this association was weaker than expected. (Author/BL)

The homogeneity test provided by L. Hedges (1982) in meta-analysis has been widely used, mainly to test if the effect sizes share the same variance. Ignoring the intercorrelations among effect sizes affects the Type I error rate. The main purpose of this research was to study the impact of pooling effect sizes on the homogeneity test in effect…

Many researchers fail to understand that reliability is a function of scores, not tests. This paper provides an explanation of the distinction as well as a description of the reliability generalization meta-analysis technique. Reliability generalization meta-analysis can provide a way to aggregate test score reliability coefficients from prior…

Examines the use of conceptual frameworks in collecting qualitative data from multiple sites. Presents strategies for devising frameworks that are flexible and general without sacrificing specificity. (JOW)
