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)

A set of methods is proposed for the analysis of opportunity to learn (OTL) in relation to achievement in large-scale educational assessments. Methods are illustrated with data from the National Assessment of Educational Progress and the National Education Longitudinal Study. Implications for large-scale educational assessment are discussed. (SLD)

The distinction between two models of reliability is clarified. Reliability may be conceived of and estimated from a true score model or from the perspective of sampling precision. Basic models are developed and illustrated for each approach using data from the author's work on measuring organizational climate. (SLD)

This article describes soft modeling with partial least squares in a nontechnical manner and suggests its greater use in special education research. This approach allows model building and evaluation in situations with high complexity but without well-articulated theories. (DB)

Describes an activity which connects mathematics and science by using data analysis and studies of animal camouflage. Includes a reproducible student worksheet to be used for data collection. (11 references) (MKR)
