Abstract

To make their system quickly usable, designers often build interfaces that reflect well-known manual activities. Demonstrates how undergraduates use their mental models for print encyclopedias to develop minimal proficiency with various electronic encyclopedias. Lower performance levels in the electronic systems are due to additional cognitive load required to adapt and develop mental models for the new systems. For the fact retrieval questions used in these relativley small data bases, the hypertext encyclopedia required less cognitive load than the 2 traditional Boolean-based systems. Adaptive designs that provide multiple system images are encouraged to support more comprehensive user understanding and more varied tasks

Abstract

School library media specialists do not know which search strategies are most appropriate for the new full-text CD-ROM databases. Reports an experiment conducted to examine the effectiveness of 2 search strategies - analytical and browse strategies - for information seeking and use among high school students using an electronic full-text ancyclopedia for the search task. The experiment sought to determine whether: a short training session in a particular information strategy allows an information seeker to form an adequate mental model of the search task; and a simple 'browse' model compare favourably with a more 'analytical' model for information seeking in a full-text online environment. Both strategies proved effective for finding relevant information yet each demonstrated distinct advantages and disadvantages. Recommends that as new technologies are introduced, school library media specialists should conduct careful observations and controlled comparisons of how students use these systems

Abstract

Reports results of a study that examined factors influencing the adoption and use of electronic networks by science and engineering faculty in 6 small universities in the southerneaster USA. Part of the study gathered data on the purpose, type, and extent of electronic communications. Data were gathered by mail questionnaire and by follow up site visits. Reports on 5 types of network use, electronic mail, electronic discussion groups, accessing remote databases, accessing remote computer facilities, and file transfer. For each service, data are reported for frequency of use by purpose: research, teaching administration, social and current awareness. Outlines preliminary use indicators for each service in terms of heavy and moderate use

Abstract

To prepare future information professionals for the rapidly changing environment in which they will work, LIS educators have an obligation to ensure that their graduates enderstand, conceptually and pragmatically, the major methodological paradigms of research. Most LIS programmes offer only a single course in research methods. Within that constraint, an important question is whether or not both qualitative and quantitative methods can be taught adequately. Suggests that, by integrating the teaching of both quantitative and qualitative methods through 'between methods' triangulation, an adequate learning experience can be achieved. Such an approach allows students to explore research problems from multiple perspectives and to evaluate critically the strengths and weaknesses of each methodology. discusses the need for such an integrated approach and suggests a scenario for applying it within the realm of a single semester course
