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

Reports results of an investigation, undertaken at Sheffield University, Departmant of Information Studies, UK into the effects of postings information (the display on the screen of the number of references in the retrieved sets) on searching behaviour. Linked online searches were conducted, on the LISA database on CD-ROM, with and without postings information. Performance in terms of the number of relevant references, precision and recall was not significantly different whether postings information was available or not; but searches with postings information took more time and more sets were viewed than in searches without postings. Searchers thought that the lack of postings information had affected 90% of their searches. Proposes that training should place greater emphasis on the value of postings information at different stages of the search and should optimize the searching behaviour of those with different searching styles

Abstract

Purpose The purpose of this paper is to develop a content analysis framework and from that derive a process model of knowledge construction in the context of virtual product user communities, organization sponsored online forums where product users collaboratively construct knowledge to solve their technical problems. Design/methodology/approach The study is based on a deductive and qualitative content analysis of discussion threads about solving technical problems selected from a series of virtual product user communities. Data are complemented with thematic analysis of interviews with forum members. Findings The research develops a content analysis framework for knowledge construction. It is based on a combination of existing codes derived from frameworks developed for computer-supported collaborative learning and new categories identified from the data. Analysis using this framework allows the authors to propose a knowledge construction process model showing how these elements are organized around a typical "trial and error" knowledge construction strategy. Practical implications The research makes suggestions about organizations' management of knowledge activities in virtual product user communities, including moderators' roles in facilitation. Originality/value The paper outlines a new framework for analysing knowledge activities where there is a low level of critical thinking and a model of knowledge construction by trial and error. The new framework and model can be applied in other similar contexts.
