A meta-analysis of 26 studies shows that accelerated gifted students outperform students of the same age and ability who are not accelerated and achieve as well as equally gifted older students in the higher grades. Correlational studies suggest that accelerates are equally successful later in life. (MLF)

A meta-analysis of findings from 31 separate studies showed that ability grouping has significant positive effects on the academic performance of elementary school children. The benefits of grouping tended to be small in the typical study of achievement --an increase from the 50th to the 58th percentile for the typical student in a grouped class.…

Inter-class ability grouping, i.e., assigning students to classes according to ability, is a controversial topic among parents, teachers, school administrators, and educational researchers. To determine the effects of inter-class ability grouping, a meta-analytic methodology was applied to 85 studies carried out in elementary and secondary…

The meta-analytic approach used in this review is similar to that described by Glass et al. (1981), whose approach requires a reviewer to locate and code studies of an issue, to code study outcomes on a common scale, and to use statistical methods to relate study features to outcomes. The studies considered for use in this meta-analysis came from…

Results from a meta-analysis of 26 controlled studies on the effects of accelerated instruction on elementary and secondary school students are presented. The examination performance of accelerates surpassed the performance of equivalent age and intelligence nonaccelerates and equalled the performance of same-grade but older, talented…

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…

A meta-analysis of findings from 108 controlled evaluations showed that mastery learning programs have positive effects on the examination performance of students in colleges, high schools, and the upper grades in elementary schools. Effects of mastery programs on student attitudes, instructional time, and college completion rates are discussed.…

The 101 computer-based education (CBE) studies considered for use in this meta-analysis came from three major sources: references in an earlier meta-analytic review of CBE at the college level (J. Kulik, et al., 1980); a computer search of the Comprehensive Dissertation Abstracts and ERIC databases; and utilization of the bibliographies contained…

Presents a meta analysis which examines results of 254 controlled evaluation studies that compared student learning in classes taught with and without computer-based instruction (CBI). Outcome measures are described, statistical analysis and effect size are discussed, and results are reported that show that CBI usually produces positive effects on…

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)

The purpose of this study was to determine the extent to which mastery testing contributes to instructional effectiveness and to determine the size of its effects in different outcome areas, such as aptitude and instructional time. A meta-analytic methodology was used to integrate findings from experimental studies. Twenty studies examined…

A meta-analysis of findings from 24 controlled evaluations showed computer-assisted instruction (CAI) usually has positive effects on adult learners, i.e., it raised examination scores and reduced instruction time. Reliable conclusions could not be reached on CAI's long-term cognitive effects because of small number of studies investigating such…
