CoLiDeS + Pic is a cognitive model of web-navigation that incorporates semantic information from pictures into CoLiDeS. In our earlier research, we have demonstrated that by incorporating semantic information from pictures, CoLiDeS + Pic can predict the hyperlinks on the shortest path more frequently, and also with greater information scent,…

Many higher education studies use self-reported gains as indicators of college student learning and development. However, the evidence regarding the validity of these indicators is quite mixed. It is proposed that the temporal nature of the assessment--whether students are asked to report their current attributes or how their attributes have…

The focus of this research is an examination of service quality provided by non-centralized technology personnel, Local Technical Support Providers (LSPs), at a southern research university. The SERVQUAL instrument was selected to measure service quality of LSPs within the Academic Affairs Division. The rationale for selecting and testing SERVQUAL…

This study investigated the extent that cooperative group members' levels of hopefulness, operationalized as a combination of pathways to meet desired goals and the agentic thinking that motivates an individual to use those pathways, predict (a) group performance, namely, the quality of an article critique assignment and research proposal…

A method for testing differential predictability in a selection model was illustrated on data from 103 male and 24 female graduate students. Since the models were not homogeneous in the variance, a method for adjusting for heterogeneity was presented. (Author/CTM)

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)

Salary data were gathered for 1985-86 from 463 faculty at the University of Northern Colorado. Discrimination variables studied included gender, race, and age, and university characteristic variables were rank, degree and tenure status, time in rank, and academic discipline. Multivariate procedures employed included multiple linear regression…

Investigates the role of academic self-esteem and academic performance in 208 U. S. college students' perceptions of the validity of their grades. Data collected through a questionnaire. Finds that regardless of self-esteem, the students with higher GPAs saw grades as more valid. This finding is in accordance with weak forms of self-enhancement…

Four methods were used to weight predictors associated with a Resident Assistant job: (1) rank order weights; (2) unit weights; (3) critical incident weights; and (4) regression weights. A cross-validation was also done. Most weighting methods were highly related. No method was superior in terms of protection from validity shrinkage. (GDC)

In contrast to linear models of human judgment developed for predictive purposes which are characteristically insensitive to the exact values of the weights utilized in them, the Linear Multiple Regression Models used for policy capturing are assumed to reflect significant aspects of the subjects' judgmental policies. This latter kind of modelling…

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)

This study identified variables which would predict first semester grade point average of nursing students. A variety of academic, psychological, and sociological data were obtained for 630 students attending three schools of nursing within the state of Indiana over a three-year period. High school grade point average, Nelson-Denny vocabulary…

The purpose of this dissertation is to provide evidence bearing on the question of the influence of the grades students receive on their ratings of the college teachers who gave them those grades. Specifically, certain characteristics of the grade distribution within each course section are evaluated as predictors of the students' ratings of the…

Although there have been numerous studies of the reliability, validity, and uses of student ratings of instruction, relatively few efforts have focused on the association of the combination of various student, instructor, and course characteristics in relation to such ratings. The purpose of this paper is to examine the relationship between…

This study used multiple regression analysis to estimate the effects of variance in teacher ratings explained by teacher-produced variability (teaching practices and/or skills) and by student-produced variability (education level, motivation, and goals) on selected student variables. Previous research suggested that these student variables…
