Examining Teachers' Decisions on Test-Type Assignment for Statewide Assessments
Peer reviewed Peer reviewed

Cho, Hyun-jeong; Kingston, Neal – Journal of Special Education, 2015
Recent studies have raised concerns about the vagueness of alternate assessment eligibility guidelines, specifically, that students with mild disabilities (SWMD) have been inappropriately assigned to alternate assessment--alternate achievement standards (AA-AAS). In this study, special education teachers (N = 317) were surveyed about SWMD in…

Heyvaert, Mieke; Wendt, Oliver; Van den Noortgate, Wim; Onghena, Patrick – Journal of Special Education, 2015
Reporting standards and critical appraisal tools serve as beacons for researchers, reviewers, and research consumers. Parallel to existing guidelines for researchers to report and evaluate group-comparison studies, single-case experimental (SCE) researchers are in need of guidelines for reporting and evaluating SCE studies. A systematic search was…

Alexander, Jennifer L.; Smith, Katie A.; Mataras, Theologia; Shepley, Sally B.; Ayres, Kevin M. – Journal of Special Education, 2015
The two most frequently used methods for assessing performance on chained tasks are single opportunity probes (SOPs) and multiple opportunity probes (MOPs). Of the two, SOPs may be easier and less time-consuming but can suppress actual performance. In comparison, MOPs can provide more information but present the risk of participants acquiring…

Gabriel, Roy M.; Hopkins, Kenneth D. – Journal of Special Education, 1974
Evaluated were three analysis strategies for evaluating instructional treatments: univariate ANOVAs (a one-factor analysis of variance for each criterion); repeated measures ANOVA (a two-factor analysis in which the criteria become the second factor); and multivariate ANOVA (a one-factor analysis in which the criteria are considered…

When Is a Picture Worth a Thousand p Values? A Comparison of Visual and Quantitative Methods to Analyze Single Subject Data.
Peer reviewed Peer reviewed
Ottenbacher, Kenneth J. – Journal of Special Education, 1990
The agreement between visual analysis and the results of the split-middle method of trend estimation was examined using a set of 24 stimulus graphs and 30 raters. Results revealed poor agreement between the two methods, and low sensitivity, specificity, and predictive ability for visual analysis in relation to statistical inferences. (JDD)

The Power of Hypothesis Testing in Special Education Efficacy Research.
Peer reviewed Peer reviewed
Sindelar, Paul T.; And Others – Journal of Special Education, 1988
Thirty-five studies on the efficacy of special class versus regular class placement for mildly handicapped students were reviewed for the power of their statistical tests. Twenty-one studies had adequate power to detect a large effect size but the power to detect a medium effect size was no better than chance. (Author/DB)

Redefining the WISC-R: Implications for Professional Practice and Public Policy.
Peer reviewed Peer reviewed
Macmann, Gregg M.; Barnett, David W. – Journal of Special Education, 1992
The factor structure of the Wechsler Intelligence Scale for Children (Revised) was examined in the standardization sample using new methods of factor analysis. The substantial overlap across factors was most parsimoniously represented by a single general factor. Implications for public policy regarding the purposes and outcomes of special…
