Examples of mathematical problems which arise outside the classroom situation are presented. The author suggests that the conceiving and solving of such problems by students would be a good way to provide the students with applications of the mathematics they learn. (JP)

Purpose of this study was to examine the effects of the true change-true initial score correlation on one aspect of the true simple change estimate, namely its error variance. (Authors/CB)

Special cases of the factor analysis model are developed for four selection situations. Methods are suggested whereby parameters in each case can be estimated using a maximum likelihood procedure recently developed by Joreskog. (Author)

Discusses how the increasing demand for higher education and the need for sharper economic restraints have focalized common awareness of the value of priority assessment by quantitative methods. The author reviews the search for more comprehensive management information systems to assist the decisionmaker. (See also EA 504 111). (Author/WM)

Article gives three plans for learning stations on mathematics dealing with measurements. Exercises deal with weight, length, and comparative measurements. (GB)

Explains how mathematics might be more efficiently used in educational administration. Reviews some recent developments reported in the social science literature on the uses of mathematics in political science, sociology, and economics. Provides some illustrations of how these developments could lead to similar applications in both the practice…

This is a continuing column of the magazine; concern in this issue is on work that might be undertaken in a simple computer appreciation course for pupils aged 15-16. Answers to why to teach computer appreciation and how staffs may be helped are given, including 14 topics that the course would cover. (DT)

Predictions using linear programing are less biased by extreme cases and thus offer a more valid estimate of expected student performance than that given by a least squares approach. (Authors/MB)
