This study conducts a meta-analysis using hierarchical linear modeling (HLM) to address the questions of the extent of gender differences in reading, whether or not these differences apply similarly across English and non-English speaking countries and decrease with age. Female secondary students performed 0.19 standard deviation units above their…

Forty-two studies comparing students with access to graphing calculators during instruction to students who did not have access to graphing calculators during instruction are the subject of this meta-analysis. The results on the achievement and attitude levels of students are presented. The studies evaluated cover middle and high school…

This article reviews research on the achievement outcomes of mathematics programs for middle and high schools. Study inclusion requirements included use of a randomized or matched control group, a study duration of at least twelve weeks, and equality at pretest. There were 102 qualifying studies, 28 of which used random assignment to treatments.…

This paper reviews definitions and issues in selective mutism in children and summarizes results of interventions conducted and published since 1982. Definitions and diagnostic criteria of the American Psychiatric Association's "Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) (1994)" and the World Health Organization's…

Selected methodological characteristics of meta-analyses related to educational achievement are reviewed in an exploration of the practice of meta-analysis and the characteristics of meta-analyses related to educational achievement, as well as possible relationships among background, methodological and substantive characteristics, and effect…

A quasi meta-analysis approach was used to examine the research methodologies used to study issues related to youth (ages 13-25) and careers. Psychlit, ERIC, Dissertation Abstracts, and four journals were searched to identify articles for the study. A total of 67 articles from 18 different sources were analyzed. Eighty-seven percent were from…

A study examined the extent to which existing data on communication apprehension (CA) can be employed to accurately reflect the cultural differences observed. The impact of those findings on the understanding of the nature of CA as it occurs in multiple cultures was also examined. Ten research reports that contained quantitative information that…

A meta-analytical literature review was performed on the literature in which computerized and paper based information retrieval systems were compared. Specifically, online catalogs were compared with card catalogs, and online bibliographic retrieval was compared with searching printed indexes. Studies which included information on relevance,…

This review of the literature on computer-assisted instruction (CAI) addresses the following topics: background and scope of CAI; current research on software and learner variables; current research on microcomputers and other delivery systems; meta analyses of the effectiveness of CAI; and methods for evaluating CAI programs. It is concluded that…

The paper provides an analysis and synthesis of studies with hearing impaired and other populations concerning the cognitive development of the principle of liquid horizontality--the idea that still water remains invariantly level regardless of the angle of the container. Three major questions focused the investigation: (1) What are the effects of…

A "best evidence" review synthesis, which incorporates features of meta-analytic and traditional literature reviews, is used in this review of studies on the effects of ability grouping on secondary school students' achievement. The focus was on 29 studies that compared between-class ability grouping to heterogeneous placements. Effect sizes were…

Statistical methodologists have sometimes criticized the use of conventional statistics in meta-analysis, and in recent years a number of them have advocated the use of a special new statistical methodology for research synthesis. An examination of recent books describing this methodology shows that it is seriously limited in its applicability to…

This first volume in a two-part report reviews completed and proposed research studies on learning needs and problems in primary education and describes research proposed for Afghanistan, Australia, Bangladesh, India, the Republic of Korea, Malaysia, Nepal, Pakistan, the Philippines, and Thailand. An introductory chapter considers the following…

Separate meta-analyses have been completed recently on the effectiveness of computer-based education (CBE) in elementary schools, high schools, colleges, and nontraditional postsecondary institutions. Several conclusions can be drawn from these meta-analyses. First, although CBA has not been uniformly successful in all its guises and at all…

A meta-analysis was conducted of 29 comparative studies located primarily through computer searches of Comprehensive Dissertation Abstracts and ERIC. Studies chosen took place in actual elementary classrooms, reported measured outcomes for both computer-based education and control classes, and were free from methodological flaws. A total of 21…
