Meta-analysis of 225 hypothesis tests of measures of memory for order (MFO) and the relationship of MFO and measures of general ability demonstrate a significant relationship between MFO and standardized test scores. Fifty-one independent samples were tested. MFO task quality was a significant predictor of effect size. (SLD)

A meta-analysis of 267 studies conducted between 1950-1980 found that auditory and visual perceptual skills can successfully increase the accuracy of predicting reading achievement, but the magnitude of increases in predictive accuracy was contingent upon the combination of variables studied and was significantly reduced if an IQ score was known.…

One of the most important effect sizes used in meta-analysis is the standardized mean difference (SMD). In this article, the conditions under which SMD effect sizes based on different measures of the same construct are directly comparable are investigated. The results show that SMD effect sizes from different measures of the same construct are…

Background: The benefits of treating stuttering close to onset have become obvious in recent years, and the Lidcombe Program has emerged as an effective and safe treatment method for children in their preschool years. The benefits of implementing the programme with young children, however, need to be weighed against the knowledge that many…

Addresses the implicit assumption that instructional media represent meaningful experimental variables independent of instructional content or strategy. Results of computer-based instruction (CBI) studies (both well-designed and flawed) and meta-analyses are reviewed to support the authors' position that this assumption is invalid, and new…

A meta-analysis of 30 studies found the following learner characteristics influenced the treatment responsiveness of early literacy interventions: rapid naming; problem behavior; phonological awareness; alphabetic principle; memory; IQ; and demographics. With the exception of the demographic category, the obtained effect sizes for the primary…

Discusses results from a meta-analysis that synthesized existing research comparing the effects of hypermedia versus other forms of instruction on students' achievement. Results suggest that the effects of using hypermedia are positive over non-hypermedia, but the effects may vary depending on what type of instruction hypermedia is compared to.…

The predictive validity and utility of assessment procedures can be increased by adding predictors to the prediction supplied by general ability tests. Of Jensen's early work comes the suggestion of focusing on the cognitive ability short-term memory (STM), especially for low-"g" Black children. Meta-analysis convincingly shows high…

Possible relationships between five test examiner characteristics (gender, race, tenure, experience as a test administrator, and experience as a test developer or scorer) and six student achievement scores (reading, writing, language usage, mathematics, science, and social studies) were studied at the school level in a statewide assessment. The…

Describes a quantitative study that examined the effectiveness of interactive video (IV) instruction by using a meta-analytic research review of the literature from 1978 to the present. Effect size as a function of study variables is examined, and test of homogeneity on effect sizes is discussed. (25 references) (LRW)

In a comprehensive review of the literature containing comparisons between boys and girls on motivation and/or achievement in science, findings were transformed into a common metric and analyzed. It was found that sex differences in both motivation and achievement are smaller than is generally assumed, but they do occur. (Author/BW)

This study is a systematic review of the Alameda County study findings and their importance in establishing a link between lifestyle and health outcomes. A systematic review of literature was performed and data indicating important links between lifestyle and health were synthesized. Although initial studies focused on the associations between…

There is increasingly negative sentiment against IQ-achievement discrepancy as a method to identify children with learning disabilities (LD) and, more broadly, intelligence as an explanation of poor academic performance. The evidence for this latter view was examined by reviewing 13 studies involving 1,542 children who were at risk or reading…

Data on the early prediction of learning problems was summarized by a meta analysis of 58 studies reporting correlations between measures administered in kindergarten or first grade and later reading achievement. The best single predictors of achievement were attention-distractibility, internalizing behavior problems, and language variables.…

Interdisciplinary and social-developmental approaches for prevention of juvenile violence are explored. Twenty-one recent works are reviewed and their approaches compared. At issue are early identification of juvenile delinquents who go on to careers of serious violence, and interdisciplinary application of modern scientific knowledge to the…
