Controversy over the merits of Null Hypothesis Statistical Significance Testing (NHST) as a tool for advancing knowledge in the social sciences has intensified in recent years. Literature for and against the use of statistical significant tests is reviewed and three major limitations of these tests are summarized. The first is that "p"…

The use of and emphasis on statistical significance testing has pervaded educational and behavioral research for many decades in spite of criticism by prominent researchers in this field. Much of the controversy is caused by lack of understanding or misinterpretations. This paper reviews criticisms of statistical significance testing and discusses…

Presents a theory of distance education to demonstrate its potential, based on a discussion of the concept of theory in general. Topics include the scope of a theory of distance education, generating hypotheses, descriptive elements and testable hypotheses generated, and the potential and applicability of the theory suggested.

Klin et al., 2004 and Levine et al., 2000 concluded that readers fail to resolve noun phrase anaphors when the antecedent is difficult to retrieve from memory and the inference is not necessary for comprehension. In four experiments we investigated the hypothesis that these inferences were actually partially encoded. Although the results of a…

Prior research has established that peer tutors can benefit academically from their tutoring experiences. However, although tutor learning has been observed across diverse settings, the magnitude of these gains is often underwhelming. In this review, the authors consider how analyses of tutors' actual behaviors may help to account for variation in…

Delineates various levels of theory with implications for research in library and information science. Based upon a review of literature on theory building and research methods in the social sciences, a model is proposed which displays a taxonomy of theory in hierarchical form. (EM)

Many research-related classes in social sciences present probability as a unified approach based upon mathematical axioms, but neglect the diversity of various probability theories and their associated philosophical assumptions. Although currently the dominant statistical and probabilistic approach is the Fisherian tradition, the use of Fisherian…

Discusses the complement and predicate (or adjunct) short clauses (SCs) in active transitive verb structures. Published Spanish literature is reviewed and evaluated, Spanish SC surface structure (SS) is described, an argument is presented against SS restructuring in Spanish, and analyses of several hypotheses are provided.

Outlines concerns that must be addressed by those who advocate replacing statistical hypothesis-testing with alternative data-analysis strategies. Suggests that commonly recommended alternatives are not perfect and that various hypothesis-testing modifications can be implemented to make the process and its conclusions more credible. Hypothesis…

Reports results of a study that was designed to empirically verify a system dynamics model that represents the relationship between dialog and structure as they relate to transactional distance and distance education. Topics discussed include discourse analysis; other variables relating to transactional distance; developing a prototype; and future…

Describes a laboratory study that examined the extent to which group gender composition affected group brainstorming performance in a computerized group support system (GSS) environment. Theory and research related to group gender composition and GSS is reviewed, and results indicate that gender composition did not affect group brainstorming…

Histories of the environmental movement have emphasized the importance of a shift in focus from those issues traditionally associated with the movement, such as resource and wildlife protection, towards "new" quality of life issues, such as environmental pollution and its human health effects. Here, time-series data between 1970 and 2000…

The purpose of this study was to explore and investigate the ways faculty at The School of Information Studies at Syracuse University use Networked Information Sources and Services to support their service tasks. Library and Information Sciences faculty were chosen as the population for this study. The study aimed to answer the following…

Proposing that most studies of nonverbal intimacy regulation have inadequately tested the compensation model (changes in any component of intimacy necessitate compensating changes in other components to maintain an equilibrium), this paper examines the nature of methodological problems in such studies and offers three suggestions for improved…

This article explores the potential of Bayesian inference as a theoretical framework for describing how people evaluate hypotheses. First, it identifies a set of logically possible forms of non-Bayesian behavior. Second, it reviews existing research in a variety of areas to see whether these possibilities are ever realized.
