This article describes a validity study conducted among middle school students comparing self-reported sun safety behaviors from a diary with readings from ultraviolet (UV) monitors worn on different body sites. The UV monitors are stickers with panels that turn increasingly darker shades of blue in the presence of increasing amounts of UV light.…

In three studies, we investigated to what extent a geometrical representation in a psychological space succeeds in predicting typicality in animal, natural food and artifact concepts and whether contrast categories contribute to the prediction. In Study 1, we compared the predictive value of a family resemblance-based prototype model with a…

The number of online education courses available to those seeking higher education have been increasing exponentially, offering opportunities to students who would not otherwise have been able to do so, as well as offering options for those who may have been able to attend classes on campus, but would prefer to pursue their course of study at…

The purpose of this paper is to measure and compare the effectiveness of a Web-based course delivery system to a traditional course delivery system. The results indicate that a web-based course is effective and equivalent to a traditional classroom environment. As with the implementation of all new technologies, there are some pros and cons that…

Attachment was assessed in toddlers with Autistic Disorder (n = 20), Pervasive Developmental Disorder (n = 14), Mental Retardation (n = 12), Language Development Disorder (n = 16), and a non-clinical comparison group (n = 18), using the Strange Situation Procedure (SSP). Children in the clinical groups were more often disorganized and less often…

The primary purpose of this study was to examine significant differences, if any, in student achievement in the area of math and science of students taught by traditionally certified teachers and alternatively certified teachers. This study examined alternatively certified teachers, as identified from through the Georgia TAPP (Teacher Alternative…

The major purpose of the present experiment was to assess the impact of student-generated and expert-generated knowledge maps on the effectiveness of post-organizer construction, initial acquisition, and transfer. Sixty students at the University of Missouri-Rolla were included in this study. Participants were required to study a passage and…

The use of stagewise regression was investigated in a university study of salary equity for full-time staff-exempt personnel. The commonly used method of regression substitution was modified in three ways: (1) shifting the emphasis away from estimating inequity and toward describing the impact of men's and women's population differences on…

Several Predictors of occupational choice derived from a theory of careers were examined. Hypotheses that a person's competencies, activities, self-estimates, interests, and vocational choices can be organized to understand and predict subsequent choice were tested. Findings support both the theory and the validity of the Self-Directed Search.…

A linear classification rule (used with equal covariance matrices) was contrasted with a quadratic rule (used with unequal covariance matrices) for accuracy of internal and external classification. The comparisons were made for seven situations which resulted from combining three data conditions (equal and unequal covariance matrices, minimal and…

The purpose of the present study is to demonstrate the utility of data analysis methodology in evaluative research relating pupil and curriculum variables to pupil achievement. Regression models which account for achievement will result from the application of the methodology to two evaluative problems--one of curriculum comparison and another…

The prediction of students' writing ability by the development of multiple regression models was investigated. Seventy-one essays and scores on the California Language Test by average seventh graders were used. Essays were entered in a modified Project Essay Grade (PEG) computer program. Results for three specific models are presented: (1) overall…

The study investigated why several minority groups in the United States have average fertility rates that differ significantly from rates of the native-born white population. Data were analyzed for social status and marital characteristics. Findings indicated that fertility differentials are too complex to be explained by references either to…

A study was conducted at a school of social work to determine the effectiveness of student decisions compared to faculty admissions decisions. Faculty predicted the performance of applicants they rated more successfully than did students. Clearly-determined admission criteria are needed to predict student performance. (SW)

Studied multiple assessors and predictors of single criterion and combination criterion for disadvantaged and regular freshmen (maximum N=143). Computed were analyses of variance and multiple correlations and regressions. Results are discussed. (Author)
