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,…

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…

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…

The status of recent research on staff development and inservice education for teachers, administrators, and other school personnel was reviewed in studies completed between 1977 and 1984.
