This introduction to meta-analysis uses examples of data reported for normal-hearing students, hearing-impaired students, and a comparison of the significance of the difference between the two. The analysis shows instruction in thinking strategies (metacognition) to be an appropriate classroom technique for improving learning with normal-hearing…

A meta-analysis of 268 studies suggested a deficit in subjects with mental retardation (compared to controls without mental retardation) across 12 categories of learning tasks, a relative deficit which remained, after training, across 7 categories of strategies. When strategy training was evaluated, the effect size was 0.701, which compares…

Presents meta-analysis of 54 articles and dissertations dealing with cognitive preferences. Information provided includes: test reliability; comparisons by country, grade level, gender, disciplines, and curricula; relationships between cognitive preferences and career orientation, science achievement, interest, and aptitude; and effect sizes.…

A study reviewed 88 doctoral dissertations written during a 4-year period in the 1980s on the use of feedback for performance improvement. The purpose was to sugget applications of the findings to teaching improvement in postsecondary education, and to determine the extent to which faculty development centers contribute to this research.…

This overview reviews a program of interlinked cross-sectional and longitudinal investigations of the nature of cognitive development in infants and young children with Down's Syndrome. The research falls into three groupings: object concept studies, operant learning experiments, and IQ studies. Early results suggest a common learning style which…

A literature search identified 39 studies assessing modality preferences and modality teaching. The studies, involving 3,087 disabled and nondisabled elementary/secondary level subjects, were quantitatively synthesized. Subjects receiving differential instruction based on modality preferences exhibited only modest gains. (Author/JDD)

In this project, a resynthesis of the research dealing with student performance in new science curricula was conducted using refined statistical procedures. Results generally supported earlier meta-analysis studies. (CW)

This meta-analysis of 49 comparative studies shows that mastery testing has positive effects on student learning, but the size of effect depends on the stringency of the criterion used and the degree of experimental control. The effects of instructional time, student attitudes, and differences in ability levels are also addressed. (Author/LRW)
