The Use of Meta-Analysis in Exercise and Sport: A Tutorial     

Jerry R. Thomas  Karen E. French 《Research quarterly for exercise and sport》2013,84(3):196-204

Abstract

Meta-analysis is a set of procedures used to quantify, integrate, and analyze the findings of a large number of research studies. It offers the advantage of quantifying effects from individual studies in addition to specifying the procedures the authors followed when reviewing the literature. Although meta-analysis has been demonstrated as a useful technique in exercise and sport research, and new and more appropriate statistical techniques for use in meta-analysis have been developed, these procedures are not widely used. This tutorial describes these advances and provides an example of their application to data from gender differences in throwing velocity during childhood and adolescence.  相似文献

Are contextual and designed student–student interaction treatments equally effective in distance education?     

Eugene Borokhovski  Rana Tamim  Robert M. Bernard  Philip C. Abrami  Anna Sokolovskaya 《Distance Education》2012,33(3):311-329

This systematic review draws from and builds upon the results of a meta-analysis of the achievement effects of three types of interaction treatments in distance education: student–student, student–teacher, and student–content (Bernard et al., Review of Educational Research, 79(3), 1243–1289, 2009). This follow-up study considers two forms of student–student interaction treatments, contextual interaction and designed interaction. Typical contextual interaction treatments contain the necessary conditions for student–student interaction to occur, but are not intentionally designed to create collaborative learning environments. By contrast, designed interaction treatments are intentionally implemented collaborative instructional conditions for increasing student learning. Our meta-analysis compared the effect of these two types of interaction treatments on student achievement outcomes. The results favored designed interaction treatments over contextual interaction treatments. Examples of designed interaction treatments and a discussion of study results and their potential implications for research and instruction in distance education and online learning are presented.  相似文献   

Note-Taking Interventions for College Students: A Synthesis and Meta-Analysis of the Literature     

《Journal of research on educational effectiveness》2013,6(3):307-333

ABSTRACT

Although note taking is frequently described as an important skill for postsecondary success, there have been few note-taking intervention studies involving multiple sessions spanning more than one week. In a systematic search, we identified seven peer-reviewed articles reporting 10 intervention studies published from 1990–2014. The only single-case design study addressed taking notes from texts, but four treatment-comparison studies that taught note taking during lectures assessed students' abilities when taking notes from texts. The remaining four treatment-comparison and one single-group design studies focused solely on note taking during lectures. Three types of notes were represented in the corpus: guided (seven studies), split-page (two studies), and self-restructured (one study). In comparing students who did and did not receive note-taking instruction, Hedges's g effect sizes on outcome measures of content learning and note quality ranged from ?0.35 to 2.11. Across nine group design studies, the weighted average effect was 0.54 (CI₉₅ = 0.47 to 0.62). The weighted average Tau-U of the single-case design was 1.00 (CI₉₅ = 0.60 to 1.40).  相似文献   

Does peer assessment promote student learning? A meta-analysis     

Hongli Li  Yao Xiong  Charles Vincent Hunter  Xiuyan Guo  Rurik Tywoniw 《Assessment & Evaluation in Higher Education》2020,45(2):193-211

Abstract

In recent years, there has been an increasing use of peer assessment in classrooms and other learning settings. Despite the prevailing view that peer assessment has a positive effect on learning across empirical studies, the results reported are mixed. In this meta-analysis, we synthesised findings based on 134 effect sizes from 58 studies. Compared to students who do not participate in peer assessment, those who participate in peer assessment show a .291 standard deviation unit increase in their performance. Further, we performed a meta-regression analysis to examine the factors that are likely to influence the peer assessment effect. The most critical factor is rater training. When students receive rater training, the effect size of peer assessment is substantially larger than when students do not receive such training. Computer-mediated peer assessment is also associated with greater learning gains than the paper-based peer assessment. A few other variables (such as rating format, rating criteria and frequency of peer assessment) also show noticeable, although not statistically significant, effects. The results of the meta-analysis can be considered by researchers and teachers as a basis for determining how to make effective use of peer assessment as a learning tool.  相似文献   

Average Effect Sizes in Developer-Commissioned and Independent Evaluations     

Rebecca Wolf  Jennifer Morrison  Amanda Inns  Robert Slavin  Kelsey Risman 《Journal of research on educational effectiveness》2020,13(2):428-447

Abstract

Rigorous evidence of program effectiveness has become increasingly important with the 2015 passage of the Every Student Succeeds Act (ESSA). One question that has not yet been fully explored is whether program evaluations carried out or commissioned by developers produce larger effect sizes than evaluations conducted by independent third parties. Using study data from the What Works Clearinghouse, we find evidence of a “developer effect,” where program evaluations carried out or commissioned by developers produced average effect sizes that were substantially larger than those identified in evaluations conducted by independent parties. We explore potential reasons for the existence of a “developer effect” and provide evidence that interventions evaluated by developers were not simply more effective than those evaluated by independent parties. We conclude by discussing plausible explanations for this phenomenon as well as providing suggestions for researchers to mitigate potential bias in evaluations moving forward.  相似文献

Media and Pedagogy in Undergraduate Distance Education: A Theory-Based Meta-Analysis of Empirical Literature   总被引：1，自引：0，他引：1  

Yiping Lou  Robert M. Bernard  Philip C. Abrami 《Educational technology research and development : ETR & D》2006,54(2):141-176

This meta-analysis employs a theoretical framework in quantitatively synthesizing empirical studies that investigate the effects of distance education (DE) versus classroom instruction on undergraduate student achievement. Analyses of 218 findings from 103 studies were conducted according to how media were used to support DE pedagogy. The results indicate that the effect sizes far synchronous instructor-directed DE were consistent and not significantly different from zero; in asynchronous DE, media only supporting independent learning was generally less effective than media supporting collaborative discussion among students, although both subsets were significantly heterogeneous. Follow-up analysis of asynchronous DE findings was framed in terms of three patterns of interaction—student-content, student-instructor and student-student.  相似文献   

Quantitative evaluation of persuasive appeals using comparative meta-analysis     

Jacob Hornik  Chezy Ofir  Matti Rachamim 《The Communication Review》2016,19(3):192-222

Message appeals are a key component of communication campaigns and an important source of campaign influence. However, research on them is heavily fragmented and it is difficult to generalize findings from the many diverse field studies. Based on a large and unique data set using quantitative and qualitative meta-analyses, this research provides measures of the relative impact of each type of appeal, as well as the major differences among them, and identifies the moderating variables that lead to a better understanding of each. This investigation is based on persuasion research, which provides a framework for understanding the unique characteristics of these advertising appeals. It highlights empirical gaps in the academic literature and acts as a conceptual guide for our research hypotheses. Results reveal weaker effect sizes than those previously reported in the literature and show important differences among appeals that lead to a “hierarchy of appeals.” Specifically, emotional appeals, led by sex and humor, appear to be more effective than fear and rational appeals. The study finds new theoretical and empirical generalizations; some results are counterintuitive and differ from findings generated from single appeal studies. Findings are of theoretical and practical importance.  相似文献
