Comments on the ideas espoused by Smedslund (PS 522 552) in this issue. Agrees to the idea of spending more intellectual energy in distinguishing between a priori and empirical hypotheses but emphasizes that concepts are not always accurate reflections of reality and that even empirical disconfirmation of an a priori hypothesis sometimes can…

The use of statistical methods to combine the results of independent empirical research studies (metanalysis) has a long history, with work mainly divided into tests of the statistical significance of combined results and methods for combining estimates across studies. Methods of metanalysis and their applications are reviewed. (SLD)

Using S. J. Messick's theoretical work concerning construct validity as a guide, underlying hypotheses for investigation when validating placement test decisions are assessed. Guidelines on validating placement decisions are offered, and the hypotheses and guidelines are applied in a validation study of the Written English Expression Placement…

Discusses semantic communication networks, methods of content analysis, and voice mail as a communication system. A study that examined conceptual distinctions between voice mail answering and voice mail messaging in a large insurance organization is described, and semantic network analysis is compared to traditional content analysis. (28…

This article argues that issues in gifted education can be usefully categorized under three headings: definitions, ideologies, and hypotheses. Seven central issues are thus classified, including the gifted label; types of giftedness; individual versus societal perspectives on giftedness; giftedness in different ethnocultural backgrounds; origins…

Describes a study of undergraduates that was conducted to define what instructors should be doing while a student is engaged in computer-based training (CBT) and to examine the effect of student-instructor interaction in CBT. Results are reported that indicate that increased interaction produces increased achievement. (11 references) (LRW)

Describes two classroom experiments that investigated the effects of using projected-display computers: the first compared teaching a course using a projected display with teaching the course in a computer lab; and the second compared using a computer and projected display with standard lectures. Effects on test scores are discussed. (three…

Describes a study conducted at Iowa State University that investigated the effects of using guided programing instruction to train analogical reasoning. Two groups of students are compared who received different types of programing instruction, and the far transfer and the near transfer of instruction are explored. (35 references) (LRW)

A study examined the content of papers presented at the second, third, and fourth national conferences of the Association of College and Research Libraries (ACRL). Analyses of the papers presented at the first national conference revealed that one-third of them were research reports, whereas proceedings from subsequent meetings contained fewer…

Describes an activity appropriate for college or high school students where they make hypotheses about prearranged patterns in a deck of playing cards. (PR)

Describes an instructional strategy to help students understand behavior variations and the factors related to that variation. Maintains that the technique helps students understand the difference between a statement of association and a hypothesis. Includes a recommended diagram to help implement the strategy. (CFR)

Describes a study of fifth graders that was conducted to determine the relationship among cognitive style, the structuring of the knowledge domain as controlled by the hypermedia software, and the test performance of the learner in terms of cognitive skill levels. Hypothesis testing and results of analysis of covariance are discussed. (Author/LRW)

Describes a study that established a measure and model for use in predicting and explaining electronic mail systems as an example of computer-mediated communication technologies usage and choice. The results indicated that all of the eight hypotheses showed significant correlation between criterion and predictor variates, supported by different…

Offers a framework for remedying some of the problems associated with the use of statistical significance tests through modifying journal editorial policies. Reviews examples from some journals that have established guidelines for reporting results of statistical significance tests. (SLD)

Investigates a hypothesis that concerns the importance of storytelling as an infrastructure that serves to create, transmit, and authenticate folklore based on a collection of Puerto Rican children's folktales with the character of Juan Bobo. Discusses cultural identity and boundaries, oral traditions, classification of folktales, and future…
