Purpose: This study investigates how the increased use of part-time and nontenure-track instructors may result in grade inflation. Design/methodology/approach: This research uses ten years of registrar data at a Midwest State (USA) institution to perform a multiple regression grade analysis. Findings: Evidence is found that part-time and…

The behavior of two real-time computer simulation models of melody recognition was compared with the performance of human subjects in this study. One of the models, INT1, recognized melodies by comparing specific intervals with stored intervals. The other model, CONT1, performed by comparing the contour of the stimulus melody with an array of…

Meta-analytic methods were used to synthesize research on the relationship between student ratings of instruction and student achievement. Results provide strong support for the validity of student ratings as measures of teaching effectiveness. (Author/GK)

Multiple regression analysis of data regarding college students' oral proficiency in using the present subjunctive after residence in a Spanish-speaking country found a significant positive relationship between length of residence and subjunctive proficiency, and a nonstatistically significant positive relationship between formal study and…

In order to explore factors that influence gender differences in same-sex friendship behaviors, the present study examined how affiliation motive, as measured by thematic apperception to same-sex cues, and affiliation value, obtained from modified Edwards (1957) Personal Preference Scale, determine type of friendship situation and its particular…

The interactions of three factors that may be involved with the memory for pattern or sequence in visual materials were investigated in this study: (1) arbitrariness of representation; (2) task; and (3) ability of students. The subjects, who were 29 graduate students in education, were pretested for general ability and randomly assigned to four…

Discusses multiple regression, a very popular statistical technique in the field of education. One of the basic assumptions in regression analysis requires that independent variables in the equation should not be highly correlated. The problem of multicollinearity and some of the solutions to it are discussed. (Author)

A search for better predictors of incomes of high school and college graduates is described. The accuracy of the prediction, implicit in the work of John R. Walsh of Harvard University, that the income differences in a given year are good indicators of income differences in future years, was tested by applying standard statistical procedures to…

Discussion of how we perceive meaning from graphics highlights a computer simulation model, UCIE (Understanding Cognitive Information Engineering), that simulates graphical perception. An empirical study is described that compared actual performance to UCIE predictions related to the amount of time required to answer a question in various…

This article (1) examines the role of idiographic theory in contemporary personality assessment and behavioral prediction methodology, (2) reviews critically empirical studies designed to evaluate the idiographic theory of individual differences in predictability, and (3) presents new data on conclusions that have been advanced toward an…

Investigates test anxiety, mathematics anxiety, and teacher feedback among university students enrolled in remedial mathematics classes to explore student motivation within an instructional framework. Results indicate that text anxiety has a significant effect on remedial mathematics students' mathematics achievement, and that informative feedback…

Sex bias in college faculty salaries is examined in this book. Part 1 contains the following four chapters on the use of multiple regression to detect and estimate sex bias in salaries: "The Assessment of Salary Equity: A Methodology, Alternatives, and a Dilemma" (Thomas R. Pezzullo and Barbara E. Brittingham); "Detection of Sex-Related Salary…

Describes a study of undergraduate students that examined the relationship between selection of college computer courses and self-perceived proficiency in using computers, computer causal attributions, and selected computer attitudes. Gender issues are addressed, correlations between variables are examined, and implications for educators are…

The strengths and weaknesses of various methodologies in conducting salary equity studies are examined. Particular attention is paid to the problems of identifying appropriate matches in the paired-comparison approach and to the sample, predictor and decision-rule problems associated with the regression analysis approach. In addition, highlights…
