A study of 64 single-subject studies examined effectiveness of social skills intervention with students with emotional or behavioral problems. The results of quantitative synthesis procedures that use a percentage of nonoverlapping data suggest that skills interventions had limited empirical support for their overall effectiveness. Implications…

This article examines the problem of definition in learning disabilities. It discusses the failure of conceptual definitions to provide a clear idea of what learning disabilities are, examines the true nature of available definitions as stipulative definitions, and notes the difficulty in conceptualizing and implementing operational definitions.…

This paper affirms H. Lee Swanson's views in "Toward a Metatheroy of Learning Disabilities" and elaborates upon the role of basic research in learning disabilities. An alternative perspective on the nature of applied research is described that views applied research as theoretically driven research aimed at practical matters. (JDD)

This paper examines studies of the Minnesota Institute which were interpreted as demonstrating that students with learning disabilities are not distinguishable from other low-achieving students. Results of the reexamination indicate that learning disabilities and low achievement can be clearly differentiated, even in studies indicating that little…

Synthesizes findings from 36 studies that validated the Dunn and Dunn Model of Learning-Style Preferences. Questions are raised regarding the validity of the model, the nature of the literature base, the interpretation of the meta-analytic findings, and the conclusions. The article concludes that the model has not been adequately validated.…

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…

Two analyses are provided to demonstrate that the population of students with learning disabilities is distinct from the population of low-achievers. Reasons for different interpretations of Bob Algozzine and colleagues' research are suggested. Assumptions surrounding the reality of learning disability are explored, as are differing perceptions…
