The inter-battery factor analysis model for predictive systems appears to offer a useful formalization of these systems and provides some guides for the development of the system. (Author)

This paper develops theory and methods for the application of the Bayesian Model II method to the estimation of binomial proportions and demonstrates its application to educational data. (Author/RK)

Results of this study suggest that certain kinds of treatment differences may be better uncovered by viewing test data in a repeated measures format. (Author/MB)

Mathematical models of library operations are presented which describe the amount of use made of resources by a user in a visit, the distribution of book circulation in a collection, the dependence of circulation on time, and the effect of multiple copies on user satisfaction.

Some proposals on how children may learn the basic multiplication facts through practical activities based on the rectangle. (MM)

This is a response to Shockley (1971) which summarizes the original Light and Smith work; outlines Shockley's criticisms; responds to the statistical issues; and concludes with the methodological implications of the disagreement. (VW)

Johnson-Neyman, Potthoff, and Erlander and Gustavsson techniques for obtaining confidence regions for the difference between regression surfaces are compared. (DG)

Essays written by 14-year-old pupils about a chemistry topic were analyzed for structure and process using ideal paradigms defined mathematically. The students' actual behaviors were then compared with the behavior expected had they used either a serial or a parallel processing strategy based on either a constructive or a reproductive memory.…

The factorial invariance of a temperament questionnaire was studied using the data provided by 24 teachers of 564 kindergarten through fourth-grade children. A LISREL analysis supported the hypothesized three-factor model and established factorial invariance of the shortened version of a behavioral rating scale constructed by Thomas and Chess.…

Presents decision-theoretic models which intrinsically include retrieval of multiple documents whereby system responds to request by presenting documents to patron in sequence, gathering feedback, and using information to modify future retrievals. Document independence model, set retrieval model, sequential retrieval model, learning model,…

The results of reanalyses of statistical procedures used in the class-size meta-analyses by Glass and Smith are reported. The analyses suggest that the use of suboptimal statistical methods did not greatly affect the results of the meta-analyses by Glass and Smith. (Author/PN)

The multitrait multimethod model of test validation is a conceptual approach for collecting, organizing, and integrating this information in making classification and intervention decisions for handicapped children. Typical problems with assessment practice are discussed with suggestions for overcoming these difficulties using the…
