This report describes the development of a teacher cost model for the Ontario secondary school system that allows educational officials, using a specified set of input information, to forecast the provincial wage-bill for a period of up to five years. The model is composed of two sub-models -- the teacher manpower sub-model and the teacher salary…

In the first chapter, the main approaches to educational planning as practiced in the member countries of the Organisation for Economic Cooperation and Development are described: (1) social demand, which subsumes current and supplementary demand; (2) investment in education; and (3) manpower needs. This chapter also reviews the contemporary use of…

A linear programing model and procedures for optimal assignment of students to attendance centers are presented. An example of the use of linear programing for the assignment of students to attendance centers in a particular school district is given. (CK)

The measurement of the evolution of illiteracy is the focus of this study. An elementary method for estimating the short-term evolution of the number of illiterates forms the subject of the first part of this analysis. This method is based on the demographic growth rate, the product of the school system and past trends. The second part is devoted…

A summary is provided of the rationale for questioning the applicability of classical reliability measures to criterion referenced tests; an extension of the classical theory of true and error scores to incorporate a theory of dichotomous decisions; a presentation of the mean split-half coefficient of agreement, a single-administration test index…

Many economists have tried to explain existing wage differentials between men and women. A new approach compares the relative importance of occupational discrimination with that of wage discrimination. This model allows for variation both in occupational distribution and in wages resulting from differences in job qualifications and productivity…

Three examples are given in which students create their own Logo software to explore the topics of number patterns and operations, fractions, and decimal parts in measurement. (MNS)

Discusses the use of a computer program designed to solve the mathematical model associated with soil nutrient uptake by plant roots and to predict the nutrient uptake. Describes a user-friendly personal computer version of this program. (TW)

Investigates the effect of state and federal grants on South Carolina local revenues for 1978 and 1982. Although local revenues are stimulated by federal aid, some of the latter is used for tax relief. (MLF)

This study tested the multifaceted, hierarchical structure of self- concept (SC) against alternative models and determined whether academic SC can be discriminated from academic grades. Results supported the multidimensional interpretation of SC and demonstrated that general SC could be interpreted as distinct from but correlated with academic SC.…

Sex differences in performance on the Australian Scholastic Aptitude Test (ASAT) were investigated. No significant direct effect of sex on performance was found. Sex differences were found to be the result of females having a higher verbal ability, males studying more mathematics, and males having greater confidence in ASAT success. (LMO)

In studies involving matrix sampling on items, it is often the case that there are too few responses per individual to use latent trait item response models. A model is formulated wherein individual level variability appears as independent error within the cells of a cross classification of demographic variables. (JKS)

Recent work in factor analysis of categorical variables is reviewed, emphasizing a generalized least squares solution and a maximum likelihood approach. A common factor model for dichotomous items is introduced, and the estimation of factor loadings from matrices of tetracorrelations is discussed. (LMO)

Reports on Commonwealth Scientific and Industrial Research Organization (Australia) efforts to establish library staffing standards by use of statistics on current library operations and comparison of figures for number of libraries. Research methodology, use of mathematical models, factor analysis and regression analysis, and measures of…

In this paper, we address mathematics education in rural contexts from a critical pedagogical perspective. We imagine our audience to be mathematics educators and rural educators who may not have background knowledge of critical pedagogy. We also confess that we are mathematics educators first, with interests in critical pedagogy and rural…
