Abstract

Undergraduates were tested to establish how they searched databases, the effectiveness of their searches and their satisfaction with them. The students' cognitive and learning styles were determined by the Lancaster Approaches to Studying Inventory and Riding's Cognitive Styles Analysis tests. There were significant differences in the searching behaviour and the effectiveness of the searches carried out by students with different learning and cognitive styles. Computer-assisted learning (CAL) packages were developed for three departments. The effectiveness of the packages were evaluated. Significant differences were found in the ways students with different learning styles used the packages. Based on the experience gained, guidelines for the teaching of information skills and the production and use of packages were prepared. About 2/3 of the searches had serious weaknesses, indicating a need for effective training. It appears that choice of searching strategies, search effectiveness and use of CAL packages are all affected by the cognitive and learning styles of the searcher. Therefore, students should be made aware of their own styles and, if appropriate, how to adopt more effective strategies

Abstract

Proposes a conceptual model to examine hypertext information presentation effects on decision making performance when compared with traditional sequentional information presentation and access. Considers which combination of task knowledge type (superficial, and causal) and information presentation styles (sequential, hypertext) yield the best decision making performance. This is achieved by comparing performance effect of hypertext and sequential information presentation when applied to superficial and causal type of knowledge required for the task. The 2 surrogates used for measuring the outcome of the performance effects are decision time and secision accuracy

Abstract

For decades print pathfinders have complemented card catalogues and been useful reference tools. They are overlooked as components of online catalogues, even though they can extend the depth of the catalogue. To encourage librarians to consider integrating pathfinders into online catalogues discusses problems in OPAC searching, describes the value and styles of pathfinders, and illustrates how to include them in a NOTIS system

Abstract

Reviews the significant changes in information technology over the last 50 years and considers the many implications for information services. The Internet, global access to distributed information sources, and remote users all present challenges to would-be providers of information services. As resources proliferate, the information professional must develop new methods for locating and accessing them: reliance on publishers and reviews is no longer sufficient. Information service providers can now serve more diverse clienteles, but must be aware of the greater range of information needs and styles of information seeking. The continuing challenge is to harness the information technologies to meet these needs

Abstract

The primary aim of the study was to investigate the effect of the absence of postings information on online searches and searching behaviour and these results were reported in Journal of information science 20(1994) no.1. The secondary aim, reported here, was to assess the cognitive styles of the participants to ensure that the population was sufficiently vareid in this respect and to investigate possible correlations between cognitive ability and searching behaviour. Throughout the project, searches were made by postgraduates at the department of information studies, University of Sheffield using the LISA database on CD-ROM. A total of 67 searchers carried out 275 searches, both with and without postings information. Reports significant differences in both searching behaviour and search outcomes obtained by those with different learning styles, with and without postings information. Significant correlations were found between cognitice styles and online searching. Searchers characterized by different learning styles tend to adopt different search strategies and strategies associated with comprehension and operation learning styles result in qualitatively different searching performance. Searching approaches associated with a versatile style are the most effective. Making feedback in the form of postings available enables comprehension and operation learners, and field independent searchers, to change their apporach in qualitatively different ways. Other findings are reported and discussed

Abstract

Experiential learning theory, introduced by Kolb, suggests that people develop different learning styles. A study was conducted to determine whether or not individuals who exhibit certain learning styles are more successful in using a hypermedia problem solving system. The Learning Style Inventory was used to classifiy subjects into 4 groups based on their learning styles: converger, diverger, assimilator, and accomodator. The study found that learning style had an impact on problem solving quality when using the hypermedia system. The preferred learning style in a hypermedia based problem solving environment is the converger. In terms of learning orientation, abstract conceptualizers performed a higher quality of hypertext based problem solving than those who prefer concrete experience

Abstract

The rapid evolution of hypermedia technology makes it possible to access an immense volume of information in an educational setting. This research examines the relationship between individual differences (in particular, cognitive styles) and navigation strategies using a WWW-based hyper-media learning system. The hypermedia learning system was used at Sheffield University's Department of Information Studies. 20 Master students were pre-tested for their cognitive styles. Dependent variables included navigation patterns, selection of navigation tools, and reactions to the hypermedia system. the results indicated that students with differing cognitive styles and individual characteristics selected different access facilities and applied different navigation patterns. The implication of these findings and the role of individual differences in designing hypermedia-based learning systems are discussed

Abstract

The third of 3 articles. Focuses on how people capture and process meaning from their situation. The analysis identified personal sense making styles that included cognitive, affective, and conative (action instinct) elements. These styles seem to also reflect a person's role in the organization and the work planning task

Abstract

Organizations are implementing telecommuter programs which meet legal, personnel, and cost constraints. Before implementation of such a programme, advantages and disadvantages to the organization and to the participating employees must be considered. Some advantages include lower costs, better recruitment and retention of employees, and better morale. Disadvantages include loss of management control and the need to change management styles

Abstract

Examines the searching behaviour of Guardian journalists searching FT PROFILE online system. Using transactional log analysis compares the searching styles of journalists with those of Guardian librarians. In some respects end users conform to the picture that professionals have of them - they search with a very limited range of commands - but in other respects they confound that image - they are very quick and economical searchers. Their behaviour relates to their general information seeking behaviour, and their searching styles would be seen in this regard

Abstract

Reports a study of undergraduate students' use of computer-based information retrieval services in relation to their cognitive and learning styles. Includes a survey of staff at Sheffield University, UK on their use of computer databases and the extend to which undergraduates are made aware of these services. Results show that undergraduate use is low and varies greatly between students of differnt faculties. Student searching behaviour was found to be basic and their performance inadequate. Significant correlation's between cognitive and learning styles and search behaviour were found. Computer-assisted learning (CAL) packages were developed and customised for 3 departments. Guidelines were drawn up based on the project's findings for introducing a computerised information sources programme into the undergraduate curriculum and preparing CAL teaching packages on information skills

Abstract

How postings information is used for inverted file searching was investigated by comparing searches, made by postgraduate students at the Dept. of Information Studies, of the LISA database on CD-ROM with and without postings information. Performance (the number of relevant references, precision and recall) was not significantly different but searches with postings information took more time, and more sets were viewed, than in searches without postings. Postings information was used to make decisions to narrow or broaden the search; to view or print the references. The same techniques were used to amend searches whether or not postings information was available. Users decided that a search was satisfactory on the basis of the search results, and consequently many searches done without postings were still considered satisfactory. However, searchers thought that the lack of postings information had affected 90% of their searches. Differences in search performance and searching behaviour were found in participants who were shown to have different learning styles using the Witkin's Embedded Figures test and the Lancaster Short Inventory of Approaches to Learning Test. These differences were, in part, explained by the differences in behaviour indicated by their learning styles
