A meta-analysis of 69 data sets ( N = 125,308) was carried out on studies that simultaneously evaluate the effects of math and verbal achievements on math and verbal self-concepts. As predicted by the internal/external frame of reference (I/E) model, math and verbal achievements were highly correlated overall (0.67), but the correlation between…

The purpose of this study was to conduct a systematic review of the secondary transition correlational literature to identify in-school predictors of improved postschool outcomes in the areas of education, employment, and/or independent living for students with disabilities.

Seven narrative and systematic reviews published since 2000 and focusing on self-determination for individuals with disabilities are reviewed in this narrative metasynthesis. The authors distinguish their work from other metasynthesis work by calling it a "narrative metasynthesis" because they include both narrative reviews and…

Although afterschool programs for children have been operating for decades in some communities, the afterschool movement--the great national awakening to the opportunity afterschool offers--is just a few years old. As public demand for afterschool has grown, so has the demand for accountability. That is particularly true in afterschool programs…

Recent years have seen increasing interest in assessing the prestige and productivity of programs in communication. An NCA doctoral reputational study was published in 2004, and a new National Research Council assessment is underway that will for the first time include the communication field. Two systems relying on objective appraisal of faculty…

Human handedness, a marker for language lateralization in the brain, continues to attract great research interest. A widely reported but not universal finding is a greater male tendency toward left-handedness. Here the authors present a meta-analysis of k = 144 studies, totaling N = 1,787,629 participants, the results of which demonstrate that the…

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…

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…
