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)

In the educational research literature alpha, the a priori level of significance, and p, the a posteriori probability of obtaining a test statistic of at least a certain value when the null hypothesis is true, are often confused. Explanations for this confusion are offered. Paradoxically, alpha retains a prominent place in textbook discussions of…

Five distribution-free alternatives to parametric analysis of covariance (ANCOVA) are presented and demonstrated using a specific data example. The procedures considered are those suggested by Quade (1967); Puri and Sen (1969); McSweeney and Porter (1971); Burnett and Barr (1978); and Shirley (1981). The results of simulation studies investigating…

Discusses the hypothesis that right hemispheric cognitive processes underlie establishment of meaning in language and in processing of linguistic gestalts, and examines several lines of evidence. Also examined is the hypothesis that societal complexity is related to differences in relative dependence upon cognitive processes controlled by cerebral…

Purpose: To deepen the understanding and to encourage further research on leadership best practices for sustaining quality improvement in UK higher education institutions (HEIs). Design/methodology/approach: The literature on leadership provides the theoretical context for the survey of quality managers from 42 UK HEIs. A mix of questionnaires,…

Reviews research into children's use of television and discusses two studies, one from the United States and one from West Germany, that focus on media in families. A study currently being completed is also described that examines the effect of cable television on children's and adolescents' media use in Austria. (LRW)

The hypothesis for this study assumed that subjects who received a diagram representing the structural relationships of a story would be more likely to solve a new and analogous problem than subjects who received two analogs without a diagram. The 151 graduate students who acted as subjects were randomly assigned to one of four treatments: one or…

Presents a theoretical formulation that integrates, within the framework of expectation states theory, theories of the emergence of power-and-prestige orders in status-heterogeneous and homogeneous task-oriented groups. Discusses a model based on this theoretic formulation. Offers a model for predicting participation rates in open interaction…

Discussion of variables that affect successful completion of external degree programs focuses on a study that investigated the association between learning style and persistence among students from the University of Wisconsin System Extended Degree Programs. Literature on distance education is reviewed, and results of the study are analyzed. (35…

The effects of the Attention Directing Strategy and Imagery Cue Strategy as program embedded learning strategies for microcomputer-based instruction (MCBI) were examined in this study. Eight learning conditions with identical instructional content on the parts and operation of the human heart were designed: either self-paced or externally-paced,…

This study tested the effects of two instructional sequences--principle-procedure and procedure-principle--on the application and transfer of learning. It was hypothesized that a principle-procedure sequence would result in better near-transfer and far-transfer and that students would prefer this sequence. The 38 freshmen enrolled in a business…

This investigation of the effect of typing skill on using a word processor for composition hypothesized that students who had learned keyboarding skills would: (1) write longer essays when using a word processor; (2) revise their essays more when using a word processor; (3) feel more positive about typing when using a word processor than students…

This paper evaluates the logic underlying various criticisms of statistical significance testing and makes specific recommendations for scientific and editorial practice that might better increase the knowledge base. Reliance on the traditional hypothesis testing model has led to a major bias against nonsignificant results and to misinterpretation…

This discussion of teaching science as a design activity emphasizes open-ended problem solving. Highlights include the relationship between teachers and students; hypotheses as solutions; and descriptions of four microworlds, or computer simulations, in chemistry, geography, physiology, and genetics which use graphic interfaces.
