Abstract

Reports on 4 experiments conducted at Sheffield University, Department of Information Studies, UK, into cognitive models which illuminate how people learn using electronic media. The experiments dealt with: learning strategies in an unconstrained electronic environment, in a hypertext environment, and in database searching, and matching and mismatching learning styles. Discusses the positive or negative implications for the design of electronic learning materials suggested by these experiments

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

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
