This study seeks to illuminate those characteristics of students which predict their performance in using evidence to test a hypothesis. The research is conceived as part of a larger investigative strategy for understanding the relationships among characteristics of students, characteristics of social studies thinking tasks, and characteristics of…

This paper is an extended series of appendices to the report "Exploring the T.R.Q.: An Assessment of the Effectiveness of the Teachers' Rating Questionnaire," Report Number 123. It should be most useful to those familiar with multiple regression analysis and factor analysis and wishing a more complex record of the statistical procedures…

This study identifies some of the change variables related to the institutionalization of the organizational component of the multiunit elementary school (MUS-E) and begins to identify some of the elements of change implicitly involved in the successful institutionalization of educational change in general. The study is based on data from five…

Most responses to educational and psychological test items may be represented in binary form. However, such dichotomously scored items present special problems when an analysis of correlational interrelationships among the items is attempted. Two general methods of analyzing binary data are proposed by Horst to partial out the effects of…

This report outlines some of the institutional factors likely to affect the demand for teachers in the Ohio labor market, including a brief description of the Ferguson Act which prohibits strikes by public service employees. The author also deals with teacher supply, including a brief assessment of the two major organizations advocating collective…

Statistical methods are described for diagnosing and treating three important problems in covariate tests of significance: curvilinearity, covariable effectiveness, and treatment-covariable interaction. Six major assumptions, prerequisites for covariate procedure, are discussed in detail: (1) normal distribution, (2) homogeneity of variances, (3)…

Scores of foreign graduate students on the Graduate Record Examinations (GRE) Aptitude Tests and the Test of English as a Foreign Language (TOEFL) were combined through multiple and moderated regression to predict grade-point average (GPA). It was hypothesized that TOEFL would moderate the relationship between the GRE scores and GPA. According to…

Production function applications to improve the efficiency of educational programs require identification of inputs and outputs and the establishment of a data bank to provide information on input and output variables. This generalizable input identification model organizes inputs for systems analysis at various levels of inputs and provides a…

The general usefulness of selected predictions equations for computer simulated scoring of creativity tests was studied. This was carried out by testing previously established prediction equations for samples drawn from similar populations. (CK)

The purpose of the study was to develop a linear programming model to be used for prediction, test the accuracy of the predictions, and compare the accuracy with that produced by curvilinear multiple regression analysis. (Author)

A study investigating interactions between imagery instructions and aptitude variables is presented. One group consisting of seven fifth-grade classes was given imagery instructions in the reading of a short text, while another group read the text in a regular way. Three different outcomes covering different types of learning were registered. As…

Beginning in Fall, 1975, applicants to Liberal Arts, Technology, and Forestry at the University of Minnesota could submit scores on either the Preliminary Scholastic Aptitude Test (PSAT) or the American College Testing Program's aptitude battery (ACT) to satisfy entrance testing requirements. This study determined that new course placement…

The Coleman Report demonstrated that family background is correlated with achievement in school. This research examined this relationship for different sexes and social classes. Family background included whether or not a child was living with both natural parents as well as the ordinal position of the child and the number of children in the…

The regression model can be used to rank resident candidates prior to interview by systematically assigning weights to the information in the transcript and then summing the weights. Much of the judgment of a residency selection committee can be incorporated in a regression model. (MLW)

Latent abilities of dental students were analyzed as causes and professional achievements as effects, with preadmission performances as indicators of latent abilities. The results demonstrate that structural analysis focuses on the direct impact of the quality of dental school education. (Author/MLW)
