A survey of studies in the "Journal of Speech and Hearing Disorders" and the "Journal of Speech and Hearing Research" found that only 12 direct replications and 15 systematic replications appeared in a total of 271 studies. Based on the probabilities of false findings in this literature, replication is recommended to verify…

Numerous forms and meanings of validity have been developed to provide researchers with the opportunity to assess the many potential sources of ambiguity that exist in any research finding. A Validity Network Schema (VNS) developed by Brinberg & McGrath (1982) is extended and elaborated in order to describe the components of the research…

Argues that a broad dimension of useful experiments would be suggested if the field supplemented its current research strategy with a second strategy focused more explicitly on the extension of generality. (HOD)

Discusses the generalization of findings from analogue therapy research to the clinical situation. Rakover contends this leads to self-contradiction and lack of scientific progress and proposes theory testing. Kazdin suggests research to determine the relationship of analogue therapy to clinical practice. (JAC)

These thoughts, by the author of a paper (EC 611 426) on having students self-record their success in meeting teachers' expectancies, examine the role of theory in guiding research and practice and the replicability of research on self-management behaviors in various special-needs populations.

This commentary on EC 606 262 (a study on the effectiveness of peer-mediated intervention on the social behavior of eight socially withdrawn preschoolers) emphasizes the importance of assessing multiple measures of integration, the need to implement research in real world settings, and the need for research on enhancing generalization and…

This study examined 40 articles published in the "American Journal on Mental Retardation" or the "Journal of the Association for Persons with Severe Handicaps" (JASH) from 1976-78 and 1986-88. Both journals published low numbers of articles with ecological validity in the late 1970s, but JASH subsequently increased…

There is some confusion in discriminating basic educational research (which explores the why's and how's of learning) from applied research (which seeks to test the implications of basic research results) because some investigations are conceived without a clear purpose. Thus, it is not uncommon for researchers to suggest implications that…
