摘要
我们对单例研究设计(SCRD)研究进行了描述性分析和荟萃分析,以调查毕业指导程序的有效性。一旦我们通过电子数据库和参考列表确定了研究,我们使用What Works Clearinghouse (WWC)标准来评估每个研究。然后,我们根据各种描述变量描述研究,通过三种非参数效应量方法计算效应量,并对研究结果进行分析。结果显示,27项研究中有11项符合或保留符合WWC标准。在11项研究中,有7项研究产生了很大的影响。在对照当代证据标准评估研究结果时,我们发现分级指导程序是一种循证实践。然而,本综述也显示,大多数被回顾的研究(n = 20)没有效果,只有三分之一的研究有中等或强烈的效果。讨论了对研究人员和从业人员的影响。
A Meta-Analysis of the Graduated Guidance Procedure
We conducted a descriptive analysis and meta-analysis of single-case research design (SCRD) studies investigating the effectiveness of the graduated guidance procedure. Once we identified studies through electronic databases and reference lists, we used What Works Clearinghouse (WWC) Standards to evaluate each study. Then, we described studies in terms of various descriptive variables, calculated effect sizes through three non-parametric effect size methods, and analyzed results across studies. Results showed 11 of the 27 studies met WWC Standards or met standards with reservation. Of the 11, seven studies resulted in a large effect. We found the graduated guidance procedure to be an evidence-based practice when evaluating the findings against contemporary evidence standards. However, this review also showed that the majority of the reviewed studies ( n = 20) had no effects and only one third of the studies had moderate or strong effects. Implications for researchers and practitioners are discussed.
期刊介绍:
The Journal of Special Education (JSE) is a multidisciplinary publication presenting primary research and scholarly reviews related to special education. The goal of this journal is to add to current scholarship and provide a sense of emerging directions in the field. Manuscripts initially are screened for (a) appropriateness of content for JSE, (b) adherence to guidelines specified in the APA publication manual, (c) readability of text, and (d) explicit statement of implications for the practice of special education.
