This paper reviews multivariate hypothesis testing, interval estimation, and discriminant analysis procedures for an aptitude-treatment interaction (ATI) analysis and illustrates the procedures with data from a large experimental study of science education at the secondary school level. The treatment variable of interest is time allowed for study…

The relationship between attrition and choice of major was studied at Western Illinois University. A secondary purpose was to determine whether measures of accademic ability, as well as curricular choice, will provide a basis for determining if attrition is likely to occur. Entering freshmen in the summer and fall terms of 1974, 1975, and 1976…

Discriminant function analyses utilizing Washington Pre-College (WPC) aptitude/achievement variables and Vocational Interest Inventory scores were performed to predict graduating major for June 1975 University of Washington graduates in 11 majors. Using both types of pre-college measures classified more graduates correctly than utilizing the…

The VARAN (variance Analysis) program is an addition to a series of computer programs for multivariate analysis of variance. The development of VARAN exploits the full linear model. Analysis of variance, univariate and multivariate, is the program's main target. Correlation analysis of all types is available with printout in the vernacular of…

The purposes for which test data should be used were described as: test should provide a learning experience for the child taking the test, the teacher giving the test, and the parents of the child. It should also provide information useful to school administrators, school boards, and state and national educational agencies. The state-mandated…

This study serves as a basis for revisions of the Organizational Climate Description Questionnaire (OCDQ) and as the second part of a larger study in which the conceptual model of climate introduced by Halpin and Croft, and the OCDQ, will be revised. The purposes were (1) to determine the factor structure of the OCDQ when a large, national sample…

Discussion of teamwork and group decision making focuses on study of undergraduates conducted to identify the variables that affect team cohesion in a business game. A literature review on small groups and business games is presented, hypotheses tested are described, discriminant analyses are explained, and suggestions for further research are…

STATGRAPHICS, a statistical package written for the IBM PC/XT/AT, is reviewed. In addition to superb graphics, STATGRAPHICS is unequalled in time series procedures, quality control, linear programming, and other mathematical procedures. The modules for regression analysis, categorical data analysis, and nonparametric analysis are good, but contain…

This study of community college students investigated predictors of student dropout in distance education courses. Considered locus of control, gender, number of distance education courses completed, age, financial assistance, and number of hours employed, and used correlation and discriminant analysis to show locus of control and financial aid…

This study investigated the contributions of initial literacy, oral language, and social adjustment to literacy achievement at the end of the kindergarten year. Data were collected across the kindergarten year from 48 children attending a school serving primarily children from low-income households with research-based curriculum and intervention…

This research study evaluated the efficacy of the "Bracken Basic Concept Scale-Revised" (BBCS-R; Bracken, 1998) and the "Bracken Concept Development Program" (BCDP; Bracken, 1986a) in a test-teach-test paradigm with students from a Head Start program. Prior to the intervention, 54 children were administered the BBCS-R and were…

Most of the research on motivation in education often uses measures taken outside the context of students' actual learning activities. This paper, however, maintains that students' motivation and learning are situated. Using a diary technique, this study explored how a class of high-achieving students in an Australian state high school (N = 34)…

Attempts to evaluate the cognitive-motivational profiles of students with reading comprehension difficulties have been scarce. The purpose of the present study was twofold: (a) to assess the discriminatory validity of cognitive, motivational, affective, and psychopathological variables for identification of students with reading difficulties, and…

In the 70s and 80s, Ohio relaxed its balanced-budget laws to give school districts more options for borrowing over the end of the fiscal year. Two provisions that permit districts to borrow against next year's revenues in order to balance the current year's budget include the Emergency School Advancement program and the Spending Reserve. This…

Students enrolled in classes which stressed learning theory and human development served as subjects in an investigation of the predictive power of observation scores compared to more traditional predictors such as grade point average and ACT scores. A stepwise discriminant analysis was employed, using the BMDP7B program on the Sperry 1100 Univac,…
