Five groups of college students, each of which had undergone a different high school biology experience, were tested with the Biological Sciences Curriculum Study (BSCS) Comprehensive Final Examination to obtain data on the lasting effects of the BSCS biology courses. The analysis of variance approach indicated highly significant differences among…

The concern of this investigation lies with the development and estimation of models explaining children's intellectual variability. Specifically, attention is directed to: (a) the role of parental status attainments and family environments in the transmission of intellectual advantage-disadvantage across generations; (b) the possibility that…

This collection of papers is based on projects done in conjunction with a senior level/graduate course, "Applications of Operations Research Techniques in Systems Engineering." These seven papers describe research studies which utilized user surveys and/or statistical methods to analyze various library operations. The papers are…

The experiment discussed in this report investigates cross cultural ability to decode emotive meaning in extra-verbal vocal expressions of mood. The principal expectation of the study is that primitive mood expressions are understood in much the same way in all the countries tested.

Failure to consider errors of measurement when using partial correlation or analysis of covariance techniques can result in erroneous conclusions. Certain aspects of this problem are discussed and particular attention is given to issues raised in a recent article by Brewar, Campbell, and Crano. (Author)

Procedures for grouping students into homogeneous subsets have long interested educational researchers. The research reported in this paper is an investigation of a set of objective grouping procedures based on multivariate analysis considerations. Four multivariate functions that might serve as criteria for adequate grouping are given and…

A statistical model designed to assist elementary school principals in the process of selection educational areas which should receive additional emphasis is presented. For each educational area, the model produces an index number which represents the expected "value" per dollar spent on an instructional program appropriate for strengthening that…

Some stochastic approximation procedures are considered in relation to the problem of choosing a sequence of test questions to accurately estimate a given examinee's standing on a psychological dimension. Illustrations are given evaluating certain procedures in a specific context. (Author/CK)

This paper investigates the influences of traditional kinds of verbal and quantitative achievement and aptitude variables on high school foreign language achievement, as measured by Modern Language Association and University of Washington tests of language skills administered to entering college students.
