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…

Describes a demonstration that helps students experience the influence of various factors on the F ratio in order for students to understand how effect size, individual differences, and measurement error combine to influence the ability to detect a false null hypothesis (power) in a one-way ANOVA. (CMK)

Describes three kinds of artifact kits (the Archaeology Dig kit, Grandmother's Trunk, and the Cultural Mystery kit) that teachers can assemble for use in their classrooms that provide links to multiple literacy events for students. Gives a list of selected sources for artifacts that will enable teachers to create artifact kits. (CMK)

This paper summarizes the results of an investigation into whether women and men have different (concrete and abstract) styles of programming, and whether the standard computing curriculum is therefore biased against women. The theory underpinning the hypothesis is critically reviewed in practical programming contexts. A concrete means of testing…

In this article, the author shares a very successful 50-minute inquiry-based physics lesson that uses only small metal cans, a bit of string, and the inquiring minds of middle schoolers. The topic of the lesson is wave motion and energy transfer. The intent of this article is to show that tests of student-generated hypotheses can be simple, quick,…

The failure of inhibition hypothesis posits a theoretical distinction between implicit and explicit access in deep dyslexia. Specifically, the effects of failure of inhibition are assumed only in conditions that have an explicit selection requirement in the context of production (i.e., aloud reading). In contrast, the failure of inhibition…

Modal and falsetto registers are the basic vocal qualities used in female speaking voices. The purpose of this study was to identify the frequency at which modal register changed to falsetto register and the frequency range of each modal and falsetto register produced under three loudness levels: soft, comfortable and loud phonations in normal and…

Given the social nature of many tasks involved in exploring and committing to a career, we hypothesized that social anxiety would correlate to exploration and commitment, even after controlling for general anxiety. We also hypothesized that self-construal and gender would interact with social anxiety in relation to exploration and commitment. In a…

A statistical test for detecting answer copying on multiple-choice tests based on Cohen's kappa is proposed. The test is free of any assumptions on the response processes of the examinees suspected of copying and having served as the source, except for the usual assumption that these processes are probabilistic. Because the asymptotic null and…
