Presents examples illustrating how to teach statistics in connection with mathematical concepts. Describes using percentage problems and graphing problems in the classroom. (YP)

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…

Describes the nature and procedure of individualized inquiry and provides an illustration of its use in one social studies classroom. Steps include problem definition, hypothesis formation, information gathering, data analysis, hypothesis testing, and drawing conclusions. Recommends that teachers select responsible, intellectually capable, and…

Suggests ways in which states that are administering a Title IV-E independent-living program may generate program and evaluation data to meet requirements of a federal program report. Presents two examples of current evaluations of independent-living programs. (RJC)

Describes a factorial experiment that is used as a laboratory exercise in a research methods course. Uses a Howard-Dolman depth perception apparatus, combining the factors of viewing condition and rod orientation to illustrate the nature of an interaction and the necessity of an additional analysis of simple main effects. (Author/LS)

Satisfactory results for interpersonally incomparable ordinal survey responses can be obtained by assuming that rankings are based upon a set of multivariate normal latent variables that satisfy factor or ideal point models of choice. Two statistical methods based upon those assumptions are described and illustrated via simulations. (TJH)

Described is an individual-placement supported-employment program for persons with traumatic brain injury. A referral pool of 32 persons is analyzed in terms of demographics, neuropsychological test performance, occupational history, occupational status, etc. Also described are program procedures, data management systems, and the role of…

Price (cost) analysis provides the library manager with valuable data for decision making and developing marketing strategies. This article examines program budget, cost-finding methodologies that influence demand, the impact of technology, and budget presentation. (Author/AEF)

This article explored the way people and connectionist models could apply knowledge of the structure of one domain to another. The process of the Simple Recurrent Network in modelling these data illustrates how abstract knowledge of artificial grammars can be understood in terms of statistical structure.

The parameters of full-information item factor models of varying dimensionality and mixed-measurement models of varying numbers of latent classes were estimated in 1,000 responses to a measure of Positive Interpersonal Engagement. The most appropriate representation of the data and deciding between mixed-measurement and dimensional representations…

Suggests ways to translate ideas in the book, "The Story of Z," into data analysis activities in kindergarten and second-grade classrooms. (MKR)
