The relationship between the philosophical orientation of a high school citizenship education program and the kinds of competencies that students exhibit on a nationally administered civics knowledge assessment was investigated. The researcher imposed a philosophical paradigm of political perfectionism on the citizenship education curriculum in…

The issue of lower than expected mathematics achievement is a concern to education leaders and policymakers at all levels of the U.S. PK-12 education system. The purpose of this quantitative, quasi-experimental study was to determine if there was a measurable difference in achievement on the mathematics section of the state test for students (n =…

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 intent of the study was to determine the extent to which test statistics computed by the unweighted means analysis are F-distributed. Applicability criteria were sought in terms of the number of factor levels and the degree to which cell frequencies differ. The unweighted means analysis, a frequently used approximate analysis, was contrasted…

Negative reactions reflected in personal as opposed to educational issues are apparent in the teacher and student groups surveyed; sex differences in attitudes are not demonstrated although sex stereotyping is evident in both groups; and socialization issues are revealed in both groups relative to dehumanizing and isolating effects of computers.…

In August 2004, the WVDE asked the Appalachia Educational Laboratory at Edvantia, Inc. to evaluate the demonstration project, in order to meet the evaluation and reporting requirements set forth in the law. According to Fink (1993), baseline evaluation data allow for subsequent analyses of the effect or impact of a program. The purpose of this…

Using two specially constructed tests for synonyms and general knowledge, researchers examined the possibility of deciding which test items will produce expected sex-differentiated results by looking at test-item contents. They found stable sex differences but very limited possibilities of identifying the test items leading to those differences.…

Medical schools have reduced the time allotted to anatomy instruction. Consequently, schools engage students in more independent settings using information and communication technologies (ICT). There has been limited research in the use of video aids, a type of ICT, to enhance anatomy examination performance. The objective of this study is to…

The purpose of this study was to develop a single procedure for comparing population variances which could be used for distribution forms. Bootstrap methodology was used to estimate the variability of the sample variance statistic when the population distribution was normal, platykurtic and leptokurtic. The data for the study were generated and…

A national study of small and large high schools was undertaken in 1984 to collect data regarding the extent of curricular offerings and then to determine whether the differences were statistically significant. Two random samples were used: the first consisted of 475 schools with enrollments of less than 400 and the second was composed of 900…

The National Survey of Student Engagement (NSSE) provides participating schools an Institutional Report that includes (among many documents) mean comparisons, frequency distributions, and student respondent data as part of its standard reporting package. Sifting through all this data can leave even experienced researchers wondering where to start…

A Monte Carlo Study was conducted to evaluate six models commonly used to evaluate change. The results revealed specific problems with each. Analysis of covariance and analysis of variance of residualized gain scores appeared to substantially and consistently overestimate the change effects. Multiple factor analysis of variance models utilizing…

STUDENT PERFORMANCE IN A SENIOR HIGH SCHOOL, SEQUENTIAL, CUMULATIVE CURRICULUM IN ENGLISH FOR COLLEGE-BOUND STUDENTS WAS COMPARED WITH THE PERFORMANCE OF SIMILAR STUDENTS TAKING TRADITIONAL COURSES OF INSTRUCTION. THE STATISTICAL STUDY SOUGHT TO DETERMINE WHETHER OR NOT THERE WAS A VALID BASIS FOR FURTHER DEVELOPMENT OF THE NEW CURRICULUM AND WHAT…

This study of 50 pairs of popular (written for layman) and technical (designed for those having specialized knowledge in particular discipline) monographs matched by subject, date of publication, and date of acquisition indicates that although technical works circulated more than popular, difference was not statistically significant. Seven…

Different approaches to defining suppression in multiple regression/correlation are compared, and their differences are illustrated. A test for determining the significance of a suppressor effect, which is based on the definition of suppression of W. F. Velicer, is extended to the general multiple predictor case and analysis of variance. (SLD)
