In 2 experiments, bimanual 1:1 rhythmic coordination was performed concurrently with encoding or retrieval of word lists. Effects of divided attention (DA) on coordination were indexed by changes in mean relative phase and recurrence measures of shared activity between the 2 limbs. Effects of DA on memory were indexed by deficits in recall…

Whereas some research on immediate recall of verbal lists has suggested that it is limited by the number of chunks that can be recalled (e.g., N. Cowan, Z. Chen, & J. N. Rouder, 2004; E. Tulving & J. E. Patkau, 1962), other research has suggested that it is limited by the length of the material to be recalled (e.g., A. D. Baddeley, N. Thomson, &…

In terms of the assessment of students, it is generally accepted that open book examinations create an enriched environment, offering the student an opportunity to better understand and respond to a particular question. The present study provided the opportunity to examine this assumption and test it in a controlled manner. During the study of an…

In this article, the author talks about e-zines, also identified as ezines. E-zines are online resources most commonly referred to as magazines or "zines" (print-world lingo for do-it-yourself publications) for short. Even though delivered over the Web, they are considered publications with small circulation and are primarily delivered over the…

The emphasis of this text is that the problems of information retrieval are the intellectual ones of subject analysis and description. These problems are not easily solved by technology alone, although certain inroads are being made by knowledge-based expert systems and other computer aids to indexing. Linguistic approaches are also showing…

A protein lacking one of the 20 common amino acids is a protein lipogram. This open-ended problem-based learning assignment deals with the evolution of proteins with biased amino acid composition. It has students query protein and metabolic databases to test the hypothesis that natural selection has reduced the frequency of each amino acid…

Comparing variability of test scores across alternate forms, test conditions, or subpopulations is a fundamental problem in psychometrics. A confidence interval for a ratio of standard deviations is proposed that performs as well as the classic method with normal distributions and performs dramatically better with nonnormal distributions. A simple…

Developed as part of CEN/ISSS Workshop on Learning Technology efforts to improve interoperability between learning resource repositories, the Simple Query Interface (SQI) is an Application Program Interface (API) for querying heterogeneous repositories of learning resource metadata. In the context of the ProLearn Network of Excellence, SQI is used…

Universities have become sensitized to the potential for students' illegal downloading of copyrighted materials. Education has been advocated as one way to curb downloading of copyrighted digital content. This study investigates the effectiveness of a university-sponsored computing ethics education program. The program positively influenced…

A hypermedia based UTICS (university transaction, information and communication system) is under development at the University of Auckland (New Zealand). This multi-platform system will provide alternatives to traditional forms of information retrieval and dissemination as well as public relations exercises. The UTICS will offer a virtual journey…

This update to a previous digest briefly describes the Internet computer network, the physical connections and communication protocols that make it possible, and the applications and information resources the network provides. The applications covered include electronic mail and listservs, the world wide web, telnet connections with remote library…

This paper describes basic types of World Wide Web pages and presents design criteria for page layout based on principles of visual literacy. Discussion focuses on pages that present information in the following styles: billboard; directory/index; textual; and graphics. Problems and solutions in Web page construction are explored according to…

The success of Computer Science Applications 109, Information Retrieval Skills, at Doane College (Nebraska) is the result of a team effort. Until the fall of 1993, the class was taught by a single instructor. During the training of a new librarian, it was discovered that a team approach might benefit the students as well as the library faculty,…

As part of its General Information Programme, the United Nations Educational Scientific and Cultural Organization (UNESCO) has for many years concerned itself with training in the use of information by preparing guides and organizing meetings and seminars on the subject. There are now an enormous number of specialized information users whose…

This manual, designed to be used with a video tape, provides information for conducting a workshop to familiarize educators with the Educational Resources Information Center (ERIC). Objectives of the workshop include: (1) to develop an understanding of the contents and structure of the ERIC database; (2) to develop an understanding of ERIC as a…
