This paper examines the unresolved epistemological and theoretical problems in comparative communication research. The first section examines what "comparative" means by reviewing various fields in the social sciences. The second section provides an overview of epistemic assumptions of comparative communication research and suggests that in the…

This study was undertaken to identify the differences between asthmatic and nonasthmatic children, ages nine through twelve, on self-concept and attitudes toward physical education. It was anticipated that children having an asthmatic condition might reflect significantly different scores from their nonasthmatic peers at least partially…

In a multiple (or multivariate) regression model where the predictors are subject to errors of measurement with a known variance-covariance structure, two-sample hypotheses are formulated for (i) equality of regressions on true scores and (ii) equality of residual variance (or covariance matrices) after regression on true scores. The hypotheses…

The purposes of this study were to examine and evaluate the importance of three variables of Bloom's mastery learning model. The variables studied were specification of objectives, use of diagnostic-progress (d-p) tests, and use of alternate resources. The study used four seventh grade and four eighth grade classes; each grade classes were…

A study to investigate the effect of training in listening to speeded discourse on listening comprehension was conducted. Specifically, the study was designed to test the following hypothesis: There is no signifant difference in the amount of gain in listening achievement of the sixth-grade pupils who received speeded discourse speech training…

Testing the hypothesis that group-centered leadership leads to less problem behavior among emotionally disturbed adolescents, 20 male and female adolescents aged 14-18 (from Karitas Community in Crystal Springs, Mississippi) were divided into leader-centered and group-centered groups and exposed to 3 weekend camping experiences. Assessments were…

This study compares attitudes of top level academic library managers with those of middle managers toward the provision of bibliographic instruction. Highlights include hypotheses and research questions; review of literature (doctoral dissertations, journal articles, reports, guidelines); methodology (design, population and sample, data…

According to Erlandson and Bifano (1987), teacher empowerment is a vital dimension of the school's organization. Lieberman (1989) defined teacher empowerment as "empowering teachers to participate in group decisions and to have real decision-making roles in the school community" (p. 24). Furthermore, Summers (2006) addressed the need for…

Mathematical tasks calling for relational thinking were given to 60 children of Indian, Pakistani, or Bangladeshi origin who had spent their school lives in England, 60 who had arrived within the past 3 years, and 60 British children. Differences in the ability to abstract, hypothesize, and generalize were studied. (KC)

Discussion of computer simulations used for exploratory learning focuses on the design of a hypothesis scratchpad that students can use for hypothesis generation and testing. An experiment with college chemistry students that compared three versions of the scratchpad is described, and the effect of the scratchpads on learning environments is…

Describes a longitudinal study of serial cancellations that was conducted by analyzing the cancellation lists between 1987 and 1990 from five midwestern member libraries of the Association of Research Libraries. Highlights include serial cancellation prices, language and place of publication, Library of Congress subject analysis, and collection…

Describes a study that used a computer survey to investigate the relationship between computer attitudes and the selected variables of age, gender, and computer knowledge among adult basic education students in Texas. Hypotheses tested are explained, comparisons are made with a national sample, and recommendations for further studies are…

Reading comprehension scores from the Wechsler Individual Achievement Tests, the Gates-MacGinitie Reading Test, and the Gray Oral Reading Test were examined in relation to measures of reading, language, and other cognitive skills that have been hypothesized to contribute to comprehension and account for comprehension differences. In a sample of 97…

The purpose of this research was to examine the validity of the 55-item Revised Token Test (RTT) and to compare traditional and Rasch-based scores in their ability to detect group differences and change over time. The 55-item RTT was administered to 108 left- and right-hemisphere stroke survivors, and the data were submitted to Rasch analysis.…

This paper reports on the effectiveness of an innovative course design that bridges classes from two different disciplines. The "Bridge" design creates assignments in two classes: a summary class and a panel class. The design encourages students to engage in teaching and interacting with their peers within and across disciplines, and…
