Questionnaires were mailed to 64 students who had completed one or more regularly scheduled Industrial Technology Education courses via the Indiana Higher Education Telecommunications System (IHETS) to determine their attitudes toward IHETS (T.V.). The IHETS system provides an alternative for delivering distance education classes, providing…

This study assessed the bipolarity of cognitive style for 970 clients of the Johnson O'Connor Research Foundation, a vocational guidance service. The 462 male and 508 female examinees were aged 14 to 65 years, with a median age of 24 years. Three cognitive style tests were investigated: (1) the Kagan Matching Familiar Figures Test (KMFFT); (2) the…

In the attempt to improve the quality of geometry instruction in schools, researchers and teachers alike have given considerable attention to the van Hiele theory of geometry learning and development, which proposes a series of cognitive levels through which every geometry student passes. This paper reports a study to determine the extent to which…

This study provides an analysis of a random sample of 100 cadets from the United States Coast Guard Academy class of 1993. Emphasis is placed on the cadets' academic achievements, their military performance, and their resignation status to determine whether the Myers-Briggs Type Indicator (MBTI) preferences can be used to predict success in these…

The Diablo Valley College (California) Research Office assessed the variation of grades in multiple-section courses and its impact on the ability to predict student success. All classes selected for the study were general education offerings applicable for the Associate of Arts degree and/or transfer, and were taught by more than one instructor. A…

By employing a concomitant variable, researchers can reduce the error, increase the precision, and maximize the power of an experimental design. Blocking and analysis of covariance (ANCOVA) are most often used to harness the power of a concomitant variable. Whether to block or covary and how many blocks to be used if a block design is chosen…

An important issue in educational and employment settings is the degree to which evidence of validity obtained in one situation can be generalized to another situation without further study of validity in the new situation. Theory, procedures, and applications concerning validity generalization are addressed. Meta-analytic techniques make possible…

A correlational analysis was performed to examine the relationship between recognition and recall test formats. A total of 236 college students completed one of four 80-item general knowledge tests; the forms contained 20 items of each of four formats: (1) true; (2) false; (3) multiple-choice; and (4) free response. Ninety-three of the subjects…

Selected methods for evaluating the stability of research results empirically are described, especially with regard to multivariate analysis. It is critically important to evaluate the influences of sampling error on obtained results; statistical significance testing does not inform judgment regarding the probable replicability or the sampling…

The relationship between selected subtests from the Armed Services Vocational Aptitude Battery (ASVAB) and corresponding subtests administered as computerized adaptive tests (CAT) was investigated using a sample of Marine recruits. Results showed that the CAT subtest scores correlated as well with initial ASVAB scores as did ASVAB retest scores,…

This paper contrasts the positions of Kane and Staiger (2002) and Linn and Haug (2002) with that of Rogosa (2002, 2003a) on the volatility in test scores as measures of school growth. In particular, these researchers disagree on whether school growth can be measured reliably in school accountability systems. The different positions of these…

One of the important underlying assumptions of all item response theory (IRT) models is that of local independence. This assumption requires that the response to an item on a test not be influenced by the response to any other items. This assumption is often taken for granted, with little or no scrutiny of the response process required to answer…

This study evaluated whether slight decrements in hearing sensitivity are associated with other communicative deficits. Data from the 38,497 students included in the National Speech and Hearing Survey (NSHS) were used to partition students into three categories of hearing sensitivity, and the prevalence of other communicative problems was computed…

This study used the Learning Style Inventory by Dunn, Dunn, and Price to identify learning style variables among school students in isolated Northeastern Manitoba communities. The importance of these learning styles to educational practice is discussed. The study sample consisted of Cree-speaking students enrolled in grades 4 through 10 at 3…
