Abstract

The aim of this study was to discover the correlation between users cognitive style and their attitude towards evaluating the system. Postgraduate students cognitive styles were defined as Verbaliser/Imager and Wholist/Analytic, and the functionality and ease of learning features of a Web-based OPAC(Online Public Access Catalogue) system were evaluated using a combined evaluation methods: interviews for the preliminary survey, a questionnaire far the central data collection, and a psychometric approach for the judgement of students cognitive style using Ridings CSA(Cognitive Style Assessment) tool. Forty-four postgraduate student volunteers responded and data was analysed using SPSS(Statistical Package for Social Science) for Windows. The statistical analysis of each feature of the evaluation, the correlation between the variables, and the features were explored using Pearsons correlation coefficients(r). In exploring the effects of the cognitive styles of individuals, this study has failed to reveal a significant (P < 0.05) correlations in the interactive Web-based OPACs evaluation. It could be said that the contribution of cognitive styles to evaluating Web-based OPACs is likely to be weaker than that of non-cognitive (or demographic) variables.

본 연구의 목적은 이용자의 인지유형과 그에 따른 웹기반 OPAC시스템 평가에 대한 상관관계를 알아보기 위한 것이다. 이용자들의 인지유형은 (1)Verbaliser/Imager와 (2) Wholist/Analytic으로 나누었고 웹기반 OPAC시스템의 (1)기능적인 측면과 (2)학습용이성 측면에 초점을 맞추어 평가를 하였다. 연구방법으로는 (1)사전조사를 위한 인터뷰, (2)주된 데이터 수집을 위한 질문지, 그리고 (3) 이용자의 인지형태 결정을 위해서 심리측정학(psychometric)방법을 사용하였다. 사전조사결과와 문헌의 리뷰에 근거하여 온라인 조사방법으로 (1)웹기반 온라인 질문지와 (2) Riding의 CSA(Cognitive Style Assessment)을 Sheffield 대학 캠퍼스 네트워크에 연결된 모든 PC에서 접속할 수 있게 온라인 테스트 환경을 구성하였다. 이 환경을 통하여 44명의 석.박사 학생들이 자발적으로 본 실험에 참가를 했으며, 이들로부터 수집된 데이터는 SPSS(Statistical Package for Social Science)를 이용하여 분석하였다. 통계분석에서 각 평가항목 변수들간의 상관관계분석을 위해서 피어슨(Pearson)의 상관계수 (Coefficient, f)를 사용하였다. 연구결과 개인의 인지형태와 웹기반 OPAC시스템 평가간에는 비교적 낮은 통계학적인 상관관계를 보였다.
