Reviews three citation-based measures for the study of journal status--influence weight, importance index, and measure of standing--to provide more convenient access to their computation. A subset of nine library and information science journals is used to illustrate simple computational procedures using the SAS statistical software package. (18…

Research over the past 15 years concerning parametric and nonparametric statistics and 10 recently developed nonparametric techniques for testing interactions in experimental design are reviewed. The new nonparametric techniques are robust, powerful, versatile, and easy to compute. A fabricated dataset is used to illustrate the technique. (TJH)

The purpose of this study was to assess the perceived effectiveness of the CourseInfo instructional technology package implemented at a regional Midwestern university. An online survey was administered, with 971 students and 44 faculty responding. Results indicate attitudes of both faculty and students were positive--both believed that the web,…

This research study compares the impact of a computer-based diglot reader with that of a sophisticated, computer-based, drill and practice program on second language acquisition. The affective benefits as well as depth and breadth of vocabulary development were examined. The diglot method, originally conceived by Burling, introduces second…

Online learning is rapidly becoming a permanent feature of higher education. In a preponderance of instances, online learning is designed using conventional educational practices: lecture, grades, group discussion, and the like. Concerns with traditional pedagogy instantiated by course management systems raise questions about the quality of…

Introduction: We investigate the conditions under which posting software known as "DeCSS" on the Internet is ethical. DeCSS circumvents the access and copy control protection measures on commercial DVDs. Through our investigation, we point to limitations in current frameworks used to assess ethical computer based civil disobedience.…

To determine which produced the most accurate item parameter estimates, four methods of item response theory were evaluated: (1) heuristic estimates; (2) the ANCILLES program; (3) the LOGIST program; and (4) the ASCAL program. LOGIST and ASCAL produced estimates of superior and essentially equivalent accuracy. (SLD)

This paper investigates three methods for comparing medians rather than means in studying two independent treatment groups. The method that gave the best results is based on a normal approximation of the distribution of the sample median where the variance is estimated using results reported by Maritz and Jarrett.

This study showed that the Elementary Perceiver and Memorizer (EPAM) can explain letter recognition phenomena earlier simulated by the connectionist Interactive Activation Model of word perception. EAPM, a model of learning and recognition in the form of a computer program, has previously explained many aspects of learning and perception. (TJH)

Peer tutoring in the use of computer software for engineering design was used at the University of New South Wales (Australia) to bring 63 students to the mastery level already attained by other students. Analysis indicated that both students and tutors (n=31) received educational benefits from this approach. (MSE)

Describes three companies' approaches to marketing and selling CD-ROM products on the World Wide Web. Benefits include low overhead for Internet-based sales, allowance for creativity, and ability to let customers preview products online. Discusses advertising, information delivery, content, information services, and security. (AEF)

Details a study of the need or wisdom of universities and colleges to include lab sections of courses that are offered to teach software. No significant difference was found in the knowledge gained for those students who participated in the lab in addition to the lecture/demonstration, but the students who participated in the lab completed their…

Discusses three innovative Internet-based electronic document delivery systems: Ariel, developed by the Research Libraries Group; Digitized Document Transmission Project, developed by North Carolina State University; and Network Fax Project, developed by Ohio State University. System are compared in terms of equipment, operation, advantages and…

Describes the evolution of courseware development and compares existing development methods, including traditional programing languages, authoring languages, and authoring systems. The use of a product which includes a customized courseware generator or authoring system is proposed, and an example is described that used HyperCard to teach the…

Discusses the variety of search command languages among online systems and provides suggestions for creating online information retrieval manuals using a database management system such as dBASE III PLUS. An online systems comparison chart is included for INFOGLOBE, INFOMART, DIALOG, QUICK LAW, and REUTERS TEXTLINE. (LRW)
