Debate is occurring about which result interpretation aides focused on examining the experimental effect should be used in single-subject experimental research. In this study, we examined seven nonoverlap methods and compared results using each method to judgments of two visual analysts. The data sources for the present study were 36 studies…

An examination of the way in which Ss were selected in research from 1968 through 1978 on behaviorally disordered students points out imprecision in methodology. The author suggests using control groups and follow-up procedures and emphasizes the need to theorize less while collecting more data. (CL)

Discusses logic and interpretation problems inherent in doing quantitative syntheses of single-case research. Addresses the meta-analytic method of using percentage of nonoverlapping data, highlighting special concerns related to withdrawal designs, sensitivity to variability in behavior, social significance of behavior change, and variables that…

In this discussion of quantitative research synthesis, past criticisms of meta-analysis are reviewed along with the ways they have been addressed. Objections to single-subject synthesis methods are discussed, along with the advantages of using the percentage-of- nonoverlapping-data metric. The article concludes by questioning the veracity of…

African American students are disproportionately likely to be identified with the emotional disturbance (ED) education disability. To investigate how teachers' perceptions of students might vary by race, we analyzed Black and White teachers' ratings of 769 students with ED, subdivided by race and grade level, on six emotional and behavior problem…
