Presents analysis of 13 studies designed to teach students with learning disabilities to write better expository or narrative text. Notes the success of these interventions, and details three components for any comprehensive instructional program: instruction in writing process, critical dimensions of different writing genres, and structures for…

Discusses issues inherent in two meta-analyses of instructional interventions for students with learning disabilities conducted by Gersten and Baker, and MacArthur et al. Issues include word recognition, technology and text comprehension, electronic enhancements, technology and writing, insufficiency of writing intervention research, and inclusion…

The conclusion of J. Cameron and W. D. Pierce that rewards do not pose a threat to intrinsic motivation (1994) is a misrepresentation of the literature based on a flawed meta-analysis. Their analysis is more an attempt to defend behaviorist turf rather than meaningful consideration of relevant data and issues. (Author/SLD)

Evaluation of two meta-analyses of sociometric research on children with learning disabilities notes differences in their findings. Differences are attributed to effects of gender, ethnicity, and type of measurement on effect size; inadequate reporting of coding reliability; failure to include similar articles for analysis; and poor…

Guidelines are offered that make it more likely that high-quality information will be extracted and coded from primary research reports in meta-analyses. It is also noted that the methodology of meta-analysis results in pressure to change the type of information that appears in primary research reports. (SLD)

Examines the relationship between teaching and research. Considers whether an emphasis on one or the other better serves the interests of communications departments. Adumbrates arguments suggesting that research undermines teaching and those suggesting the converse. Shares the results of a meta-analysis of existing research on the topic. Finds a…

This meta analysis reviewed 30 studies comparing child-based cognitive-behavioral therapy (CBT) for antisocial behavior. Results showed that child-based CBT interventions had a small to moderate effect in decreasing antisocial behavior. Future research directions, including the integration of individual training into group therapy and the…

Shares three ideas concerning how to evaluate the practical importance of developmental findings to make them more useful to policymakers: (1) statistical significance tests need to be accompanied by effect size estimates; (2) meta-analyses are helping in using all existing data when examining issues involved in policy debates; and (3) researchers…

Most research in music education has so far dealt with music training in institutional settings, such as schools, and is accordingly based, either implicitly or explicitly, on the assumption that musical learning results from a sequenced, methodical exposure to music teaching within a formal setting. However, in order to realise and understand the…

This work provides a correlation study of the role of the following cognitive variables on problem solving in elementary physical chemistry: scientific reasoning (level of intellectual development/developmental level), working-memory capacity, functional mental ("M") capacity, and disembedding ability (i.e., degree of perceptual field…

The major youth psychotherapy meta-analyses have relied on published studies, which may have led to biased effect size estimates. To examine this possibility, the authors compared 121 dissertations with 134 published studies and found the following: (a) few differences on individual methodological variables, but, overall, stronger methodology in…

This study conducted a systematic review to assess the quality of existing literature on psychological treatments for irritable bowel syndrome and to quantify the evidence for their efficacy. Three independent reviewers (2 from England, 1 from the United States) coded the quality of 32 studies, 17 of which provided data suitable for meta-analysis.…

Calculation of the statistical power of statistical tests is important in planning and interpreting the results of research studies, including meta-analyses. It is particularly important in moderator analyses in meta-analysis, which are often used as sensitivity analyses to rule out moderator effects but also may have low statistical power. This…

The purpose of this study was to quantitatively combine and examine the results of studies examining the effectiveness of periodized (PER) compared to nonperiodized (Non-PER) training programs for strength and/or power development. Two analyses were conducted to (a) examine the magnitude of treatment effect elicited by PER strength training…

This study examined the extent to which readers integrate information from related texts as a function of both top-down evaluation processes and bottom-up resonance. In Experiment 1, participants read and recalled ambiguous texts about events that were preceded by a descriptive text (primer) of the event. Participants' recall of the ambiguous…
