Evaluates, in question/answer form, the available research literature on giving instructions/directions in terms of their effect on learning; presents a few guidelines on writing directions for practitioners; and points out some "missing links" in the area of research. (Author)

This article proposes several models for the analysis of mobility tables and examines the relationship of these latent structure models to some earlier mobility models, including the 'perfect' and the 'quasi-perfect' models. Uses of each of these models to derive various kinds of substantive inferences are suggested. (DB)

An in-depth examination of nine research studies indicates that 1977 opinions about competencies needed for operating effectively as a community education administrator were not significantly different from those in 1959. A research study is proposed. (Author/MLF)

In response to S. A. Cohen's paper on research problems in learning disabilities, the author suggests that ecological methods are equally valid scientifically as experimental methods if the problem is well conceptualized. (DB)

In response to S. A. Cohen's paper on research problems in learning disabilities, the author agrees that there has been too much ex post facto correlational research and reliance on etiological labels but emphasizes that not enough attention has been paid to the formulation of sound theory underlying research hypotheses. (DB)

Examines the period of adolescence in terms of Piagetian genetic epistemology and psychoanalytic ego psychology regarding implications for research in response to literature. (DD)

Presents a dialog between the two editors of this issue, discussing and debating why communication researchers should study the Internet, and how the topic can be conceptually constrained. (SR)

Triangulates Christie's findings with other research on the evaluation practice-theory relationship and offers additional methods and directions for future research on evaluation practice. (SLD)

A literature review explored issues of mentoring in a computer-mediated context: the effect on mentor roles, influence of type of mentoring, challenges (miscommunication, technical difficulties, privacy), and opportunities (access to mentors, reduced costs, status equality). Areas for research and a typology of computer-mediated mentoring were…

Reports the results of a qualitative study of success factors and barriers to the development of virtual knowledge-sharing communities of practice at Caterpillar Inc. Identified prerequisites for successful knowledge management through virtual communities of practice, as well as barriers to virtual community development, and discusses future…

Reviews the progress of parallel computing in information retrieval (IR) and stresses the importance of the motivation in using parallel computing for text retrieval. Analyzes parallel IR systems using a classification defined by Rasmussen; describes retrieval models used in parallel information processing; and suggests areas of needed research.…

Reviews research evaluating the effectiveness of computer-assisted career guidance systems, stressing the limited number of studies. Highlights the need for more research using larger, diverse samples; sound procedures; and investigation of the interaction between client attributes and treatments. (SK)
