In 1975 the Ontario Ministry of Education assigned major responsibilities in curriculum development to local school boards. School boards responded by establishing or expanding special units to develop local programs. At the present time, the organization of these units or program departments varies widely. The focus of the present study is to…

The purpose of this paper is to illuminate the advantages of path analysis for the exposition of results in data analytic papers. Probably the greatest advantage is that it provides a means by which the nature of the problem may be handily summarized. The method of path analysis, although conceived over sixty years ago by Sewell Wright, has only…

Examination of the relevant literature indicates that most studies of school structure and interpersonal relations have either been too narrow in scope, too theoretical, or too tied to the individual as the unit of analysis to support any conclusive generalizations. A search of the literature for appropriate variables to include in a more complex…

This study, carried out in connection with the 1971-72 field test of the "Developing Mathematical Processes" program, was an investigation of relationships among the teacher characteristics, teaching behaviors, and criterion-referenced student performance in mathematics. Students in 15 class samples of size six, along with their…

A general procedure is presented for generating code values for a qualitative variable in multiple linear regression analyses that result in directly interpretable estimates of interest. The basic approach, in viewing ANOVA as a multiple regression problem, is to derive quantitative code values for the various levels of the qualitative ANOVA…

Data from 80 junior high school students who completed the Assessment of Language and Reading Maturity (ALARM) test battery were used to delineate elements within the concept of mature reading comprehension. Stepwise multiple regression analyses were performed on the 15 ALARM test factors to isolate both the principal elements and the "trace…

Joreskog has developed a very general and powerful model and computer program for analyzing relationships among variables, called LISREL. Structural analysis of covariance matrices by Joreskog's LISREL method is proposed as an alternative to regression methodology in the analysis of aptitude-treatment interaction (ATI) data. LISREL resolves some…

Brief descriptions are provided of general-purpose mathematical and statistical software, including 27 "stand-alone" programs, three subroutine systems, and two nationally recognized statistical packages, which are available in the Air Force Human Resources Laboratory (AFHRL) software library. This index was created to enable researchers…

This report documents the theory, structure, and implementation of a performance processor (written in FORTRAN IV) that can accept performance demonstration data representing various levels of operator's skill and, under user control, analyze data to provide candidate performance measures and validation test results. The processor accepts two…

The efficacy of a variety of selection measures in predicting successful performance in Air Force physician assistant training were investigated. Variables identified for the analysis of 51 subjects (graduates of the Air Force program) were: Scholastic Aptitude Test (SAT, combined verbal and mathematics composites), Airman Qualifying Examination…

The present paper contributes to research methodology as practiced in the field by providing practitioners with a concise statement of the problems in analyzing unbalanced designs, and by clarifying the conditions under which the analysis alternatives are most appropriate. The purposes of the present paper are: (1) to examine the analysis…

The process of selecting applicants for admission to a new school of medicine (Southern Illinois University School of Medicine) is examined through the use of multivariate regression techniques. More than 250 variables were analyzed and classified as to source of data: student American Medical College Application Service (AMCAS) application,…

Recent trends in college admissions are discussed in terms of their influence test validation procedures. In particular, the effects of new college admission practices are considered with respect to the problem of validating placement tests. Traditional test validation techniques are reviewed and compared to the needs specific to placement tests;…

Using data originally report by others, this paper focuses on the relative merits of three separate statistical approaches to measuring occupational sex discrimination. The sample was a national probability sample of 539 women and 993 men. Demographic factors such as race, sex and age, education, job tenure and supervisory status served as the…

This paper describes an adaptation of Dyer's regression model that uses data on individual students in an attempt to isolate the influence of different schools on variations in student achievement growth. This procedure involves comparing the results of a multiple regression analysis of individual student achievement scores and several…
