This meta‐analysis synthesized 26 published single‐case design (SCD) studies on Tier 2 behavior interventions implemented within the educational framework of school‐wide positive behavioral interventions and supports. We used Tau‐U indices to determine the overall magnitudes of effect of the Tier 2 behavior interventions and the potential variables that moderate improved student behavioral outcomes. The 26 studies that were analyzed included a total of 243 student participants. The studies were evaluated to determine whether and to what extent they met What Works Clearinghouse (WWC) SCD standards. Of these, 10 studies were confirmed as meeting WWC SCD standards with or without reservations. Notable findings were that outcomes for students in kindergarten and secondary grade levels were limited, and insufficient screening methods were used to identify and select students needing Tier 2 interventions. The results indicate that the literature reports Tier 2 interventions with effect sizes ranging from 0.26 to 0.98. Average effect size for social skills instruction was found to be large, whereas Check‐in/Check‐out, group contingency, and intervention packages had medium effect sizes. Moderator analyses indicated different effect sizes across intervention types, outcomes, and implementers. The results are discussed in relation to implications for practice, limitations, and future research. 相似文献

The Effects of Read‐Aloud Accommodations for Students With and Without Disabilities: A Meta‐Analysis
Hongli Li 《Educational Measurement》2014,33(3):3-16
Read‐aloud accommodations have been proposed as a way to help remove barriers faced by students with disabilities in reading comprehension. Many empirical studies have examined the effects of read‐aloud accommodations; however, the results are mixed. With a variance‐known hierarchical linear modeling approach, based on 114 effect sizes from 23 studies, a meta‐analysis was conducted to examine the effects of read‐aloud accommodations for students with and without disabilities. In general, both students with disabilities and students without disabilities benefited from the read‐aloud accommodations, and the accommodation effect size for students with disabilities was significantly larger than the effect size for students without disabilities. Further, this meta‐analysis reveals important factors that influence the effects of read‐aloud accommodations. For instance, the accommodation effect was significantly stronger when the subject area was reading than when the subject area was math. The effect of read‐aloud accommodations was also significantly stronger when the test was read by human proctors than when it was read by video/audio players or computers. Finally, the implications, limitations, and directions for future research are discussed. 相似文献

Single‐subject designs provide the special education field with an alternative to group designs. The purpose of this paper is to introduce the topic of single‐subject designs by providing an overview of the relevant literature and a discussion of the major issues and applications of these designs in the field of special education. This paper is divided into four main sections: (1) characteristics of single‐subject designs; (2) types of single‐subject designs; (3) advantages of single‐subject designs; and (4) issues and concerns regarding single‐subject designs. It was concluded that a minimum of three measurements in each phase is typically required until there is a clear pattern. Flexibility and cost‐effectiveness are among the main advantages of these designs. External validity and generalisability are the main concerns. However, meta‐analytic studies can enhance the generalisability of single‐subject designs findings within similar context. Conclusions and recommendations to improve these designs are discussed. 相似文献

An effect size of about .70 (or .40–.70) is often claimed for the efficacy of formative assessment, but is not supported by the existing research base. More than 300 studies that appeared to address the efficacy of formative assessment in grades K‐12 were reviewed. Many of the studies had severely flawed research designs yielding uninterpretable results. Only 13 of the studies provided sufficient information to calculate relevant effect sizes. A total of 42 independent effect sizes were available. The median observed effect size was .25. Using a random effects model, a weighted mean effect size of .20 was calculated. Moderator analyses suggested that formative assessment might be more effective in English language arts (ELA) than in mathematics or science, with estimated effect sizes of .32, .17, and .09, respectively. Two types of implementation of formative assessment, one based on professional development and the other on the use of computer‐based formative systems, appeared to be more effective than other approaches, yielding mean effect size of .30 and .28, respectively. Given the wide use and potential efficacy of good formative assessment practices, the paucity of the current research base is problematic. A call for more high‐quality studies is issued. 相似文献

The number of Social StoriesTM studies and reviews has increased in recent years, yet concerns regarding quality and effect sizes continue to be expressed. With the emphasis on evidence‐based practices (EBPs) for the education and treatment of people with autism spectrum disorders (ASD), this issue becomes of paramount importance as professionals and parents attempt to select interventions for the people with ASD in their care. The current study makes a unique contribution in its use of an extensive EBP evaluation model to examine 33 single‐subject studies across 13 peer‐reviewed journals, a 12‐year period, and a wide range of grouping variables. Using the Mayton, Wheeler, Menendez and Zhang (2010) EBP evaluation protocol, studies were investigated in terms of eight quality indicators comprised 23 operationally defined standards. Studies included in this analysis met the following criteria: (1) they were intervention studies using single‐subject research designs; (2) they included only participants with disorders on the autism spectrum; and (3) the primary intervention was the use of a Social Story. Findings included on‐ or above‐standard acceptability in EBP indicators related to important aspects of dependent variables within studies and below‐standard acceptability in indicators related to both internal and external validity of studies. 相似文献

Statistical significance testing is the cornerstone of quantitative research, but studies that fail to report measures of effect size are potentially missing a robust part of the analysis. We provide a rationale for why effect size measures should be included in quantitative discipline-based education research. Examples from both biological and educational research demonstrate the utility of effect size for evaluating practical significance. We also provide details about some effect size indices that are paired with common statistical significance tests used in educational research and offer general suggestions for interpreting effect size measures. Finally, we discuss some inherent limitations of effect size measures and provide further recommendations about reporting confidence intervals. 相似文献

Statistical methods are increasingly being used to integrate findings from the ever‐expanding universe of empirical research. Meta‐analysis encompasses various techniques for synthesizing summary statistics, and mega‐analysis pools raw data across studies. This paper offers an introduction to meta‐analysis and mega‐analysis that complements the study of analysis of variance (ANOVA). After a brief conceptual discussion, we provide simple numerical examples. 相似文献

The purpose of this study was to compare 12 commonly‐used nonoverlap methods with each other and with the results of visual analysis. Data were obtained from 25 studies focused on embedded instruction and schema‐based instruction and included a total of 101 graphs. Treatment effect estimates using 12 nonoverlap methods were calculated for each graph by hand or using an online calculator. Five experts conducted visual analysis of each graph. Results showed that strong agreements existed between visual analysis and PND, TauNOVLAP and Tau‐U when raw data were analysed, and PND, PNCD and PEM‐T when categorised data were analysed. Of the 12 methods investigated, PND had the highest agreement rate with visual analysis, followed by PEM‐T, PAND, PNCD, IRD, NAP and TauNOVLAP. Overall, visual analysis appeared to be more conservative, as most nonoverlap methods overestimated the treatment effect. Additional research is needed to replicate and potentially validate the findings of this study. 相似文献

Q‐methodology, traditionally a tool for phenomenological analysis, single‐subject or small sample research, and typological analysis, has potential for research in human communication. Unfortunately, q‐techniques have often been neglected or misunderstood by main‐stream social scientists. This article presents basic information regarding the construction of q‐sorts, discusses methods for analyzing q‐sort data in a variety of research contexts, and identifies resources which may be consulted by those wishing to learn more about the method. 相似文献

Measures of Effect Size for Comparative Studies: Applications, Interpretations, and Limitations 总被引：2，自引：0，他引：2
Although dissatisfaction with the limitations associated with tests for statistical significance has been growing for several decades, applied researchers have continued to rely almost exclusively on these indicators of effect when reporting their findings. To encourage an increased use of alternative measures of effect, the present paper discusses several measures of effect size that might be used in group comparison studies involving univariate and/or multivariate models. For the methods discussed, formulas are presented and data from an experimental study are used to demonstrate the application and interpretation of these indices. The paper concludes with some cautionary notes on the limitations associated with these measures of effect size. Copyright 2000 Academic Press. 相似文献

This meta‐analysis synthesized research on math performance outcomes for English learners (EL) as a function of language‐focused (math vocabulary) interventions. We included group and single‐subject design studies with children from kindergarten to 8th grade (3,766 students for group, 30 for single‐subject). Group studies yielded a mean Hedges’ g of 0.26 in favor of the interventions relative to the control conditions, whereas single‐subject studies yielded a mean Percentage of Non‐Overlapping Data of 81.01% and Phi coefficient of .66 relative to baseline. Although group studies yielded small effect sizes (ESs), we found significant moderators for grade level, intervention focus, and length of intervention. Single‐subject studies yielded higher ESs than group studies, and were considered generally effective, with a high ES. This finding was attributed to a direct focus on children with math difficulties and one‐to‐one instruction. The implications for practice and future research are discussed. 相似文献

The promise of time-series designs for educational research and evaluation is reviewed. Ten time-series designs are presented and discussed in the context of threats to internal and external validity. The advantages and disadvantages of various visual and statistical data-analysis techniques are presented. It is argued that time-series research paradigms are useful when researchers (a) wish to involve a single subject in experimental research (individuals as units of analysis) or conduct program-evaluation studies (aggregates as units of analysis), (b) are interested in nearly continuous measurement, (c) cannot meet conventional design and statistical assumptions, or (d) wish to specify individual differences through N = 1 research strategies. It is also suggested that more research endeavors be devoted to combining unique characteristics of time-series research with conventional multi-unit paradigms. 相似文献

Experimental intervention studies constitute the current dominant research designs in the autism education field. Such designs are based on a ‘knowledge‐transfer’ model of evidence‐based practice in which research is conducted by researchers, and is then ‘transferred’ to practitioners to enable them to implement evidence‐based interventions. While these research designs contribute important knowledge, they lead to a gap between what the research evidence may prescribe and what happens in practice, with a concomitant disparity between the priorities of researchers and practitioners. This paper discusses findings from the ESRC‐funded ‘SHAPE’ project, which adopted a different model of evidence‐based practice, focusing on knowledge co‐construction. Pupils (N = 8), teachers (N = 10), a speech and language therapist and a parent in three different school communities investigated creative ways in which children's social communication skills could be enhanced through technology use. Through a participatory methodology, digital stories were used as a method to enable engagement with the practical realities of the classroom and empower practitioners to construct and share their own authentic narratives. Participants articulated precise knowledge about the learning opportunities afforded to them and their pupils through quality interactions that were mediated by the technologies, as evidenced through digital stories. The SHAPE project shows that it is feasible to develop methodologies that enable genuine knowledge co‐construction with school practitioners, parents and pupils. Such co‐construction could offer realistic opportunities for pedagogical emancipation and innovation in evidence‐based practice as an alternative to the currently dominant and narrow model of knowledge transfer. 相似文献

The purpose of this article was to present a synthesis of the peer‐reviewed differential bundle functioning (DBF) research that has been conducted to date. A total of 16 studies were synthesized according to the following characteristics: tests used and learner groups, organizing principles used for developing bundles, DBF detection methods used, and types of bundles that indicated statistically significant DBF in the hypothesized direction on multiple occasions. The article concludes with a list of suggestions to individuals who conduct DBF research. For example, effect size guidelines should be established for interpreting the amount of DBF in bundles of items assessed with simultaneous item bias test (SIBTEST), given that it is the most commonly used DBF procedure. This would reduce our reliance on statistical significance testing. General effect size guidelines are needed as well as guidelines for special circumstances like small sample cases. Other useful suggestions are offered as well. 相似文献

Single‐case research methods provide a basis for demonstrating that an intervention produces a reliable change in a targeted outcome for individual cases. To supplement visual analysis of data in single‐case studies, researchers frequently report statistics—often referred to as effect sizes—to summarize study findings. The recent proliferation of effect sizes used in single‐case research can be confusing. In this article, after reviewing single‐case research, we provide an overview of common types of effect sizes used in single‐case research, including overlap metrics and within‐ and between‐participant effect sizes, and conclude with examples of these effect sizes in the single‐case literature. Our take‐home message is that effect sizes are useful complements to visual analysis when interpreting results of single‐case design research studies. 相似文献
