The hypotheses that sex differences in spatial ability may result from differences in spatial experience, and that training can improve spatial skills regardless of sex, are tested. Meta-analytic techniques are used. Relationships between spatial activity and ability, and the improvability of spatial test performance for both sexes, are confirmed.…

Eight articles discuss the teaching of evaluation methods through the process of performing evaluations. Four articles concentrate on evaluation as taught in higher education and professional education, and four articles deal with the four-state East Central Acquired Immune Deficiency Syndrome Education and Training Center Project. (SLD)

This metanalysis reviews 32 studies that compared 2 groups of students receiving identical writing instruction, with only 1 group using word processing for writing assignments. Word processing improved the quality of student writing but did not improve student attitudes. Suggestions are given for using word processing more effectively. (SLD)

A review of 66 reports involving science education for students with disabilities finds that specific instructional strategies and techniques have produced generally beneficial effects. Results support previous recommendations for science education based on documented characteristics of these students using appropriate instructional variables,…

This meta-analysis with literature review considers whether the self-concepts of gifted and nongifted children differ and explores the effects on self-concept of labeling a child as gifted and placing the child in special programs. Studies indicate a generally higher academic self-concept among gifted students. (SLD)

This article summarizes the critical findings of recent research syntheses concerning intervention with students who have learning disabilities. The syntheses examined research on higher-order processing and problem- solving, reading comprehension, written expression, and grouping practices associated with improved outcomes in reading. Principles…

Used meta-analysis to examine premise that the early child-parent bond is reflected in interpersonal relationships across the life span. Found that overall effect size (ES) for child-mother attachment was small to moderate. ESs were similar in studies using Strange Situation and Q-sort methods. ESs were larger for middle childhood and adolescent…

A meta-analysis was conducted of 14 studies examining whether whole-language instruction increases the reading skills of low-SES students in grades K-3. Evidence suggested that low-SES primary school children do not benefit from whole-language instruction, compared to basal instruction. Findings indicated that there may be some advantages to the…

This article uses meta-analytic findings to evaluate six special education interventions: psycholinguistic training, perceptual-motor training, modality-matched instruction, and treatments for attention deficit hyperactivity disorder (stimulant medication, diet modification, and social skills training). Findings are related to decision making in…

This dialogical project is framed within critical inquiry methods to bring an Amish teacher's voice to the forefront. Henry, an Amish middle school teacher, and two university teacher educators in northeastern Indiana collaboratively critiqued educational literature written about the Amish culture from the past 15 years. Building on critical…

This paper reviews research on grouping of students within classes and its effects on learning. Primary consideration is given to grouping and mixing students by ability, though consideration is also given to grouping and mixing students by ethnicity and gender as well as to research on the effects of group size. Results of meta-analyses of…

Introduction: This article critiques the questions asked and methods used in research syntheses in continuing education (CE) in the health professions, summarizes the findings of the syntheses, and makes recommendations for future CE research and practice. Methods: We identified 1.5 research syntheses published after 1993 in which primary CE…

This study summarizes the results of a quantitative synthesis of the retrievable primary research dealing with the effects of new science curricula on student performance. This study synthesizes the results of 105 experimental studies involving more than 45,000 students and utilizes the quantitative synthesis perspective to research integration…

The communication theory and methodology section of the Proceedings contains the following 20 papers: "Political Adwatches and the Third-Person Effect" (Ekaterina Ognianova and others); "Understanding Adopters of Audio Information Services" (Kimberly A. Neuendorf and others); "A Principal-Agent Approach to the Study of…

A quantitative synthesis of multivariate studies in science education during the past ten years yields evidence to support a model of achievement in science very much like that currently proposed in the literature of expert problem-solving. Despite previous claims, spatial visualization and verbal ability predict additional variance in achievement…
