In a Delphi study of research needs in educational technology, 89 experts suggested 163 research needs. High-priority needs were identified by the Scree test--a method usually restricted to factor analysis. The usefulness of the technique for analysis of survey results suggests that it should be extended to other applications. (SLD)

Discussion of computer-assisted psychological evaluation focuses on its use as legal evidence. Topics discussed include legal criteria for expertise; clinical psychology and standards for expertise; factors relating to reliability and validity, including the proper use of data; computerized test administration; computer-based test interpretation;…

Three conceptual approaches to estimating local child abuse rates using the National Incidence Study of Child Abuse and Neglect data set are evaluated. All three approaches yield estimates of actual abuse cases that exceed the number of reported cases. (SLD)

Describes a naturalistic paradigm and discusses the value of using a naturalistic, or qualitative, approach to study the effectiveness of computer-based instruction (CBI) and to design effective courseware. Topics discussed include data collection; data analysis; and findings of naturalistic studies of CBI effectiveness. (53 references) (LRW)

A handheld computer observation system was developed using Hewlett-Packard HP71B computers for recording and IBM-PCs for storing and analyzing data. Algorithims used in observing interactions between handicapped children and peers or teachers are described. Also described are behavior definitions, observer training and observation procedures, the…
