The Efficiency of Hypermedia Material:Study on Hyperlink and Node that Affect User's Perception
Abstract
하이퍼미디어 자료를 이용한 교육훈련이 다른 자료의 이용보다 효율적이란 연구는 많이 되어 왔으나 하이퍼미디어 자료의 효율적인 구성에 관한 연구는 미진한 실정이다. 이에 이 연구는 하이퍼미디어의 기본 구성요소인 하이퍼링크와 노드를 처리변수로 하고 사용자의 편의성과 유용성에 대한 인식을 종속변수로 하여 하이퍼링크의 숫자와 노드의 크기가 사용자의 하이퍼미디어 자료에 대한 유용성과 편의성 인식에 어떻게 영향을 미치는지에 대해 밝히고자 했다. 먼저 2×3 팩토리얼 디자인에 따라 각각 다른 처리변수의 조합을 가진 6개의 하이퍼미디어 자료가 구축이 되었으며 경영대 학생들을 대상으로 ?피窩? 하여 자료를 수집했다. 수집된 자료는 타당성 검사와 신뢰성 검사를 거친 뒤 통계적 분석을 하였다. 종속변수에 대한 상관관계가 검사되었으므로 다변량 분산분석으로 처리변수의 종속변수에 대한 통계적 유의성을 검사했으며 단변량 분산분석 중 이원배치분산분석으로 각각의 종속변수에 대한 처리변수의 영향을 검토했다. 인구통계학적 자료의 종속변수에 대한 상관관계가 발견됨에 따라 다변량 공분산분석과 단변량 공분산분석을 통해 인구통계학적 자료의 영향을 조사했다. 마지막으로 평균차이 분석을 통해 실험 참가자들의 선호도를 조사했다. 본 연구의 결과를 요약하면 처리변수는 사용자 인식 편의성과 인식 유용성에 영향을 미치고 하이퍼링크 수와 노드 크기가 하이퍼미디어의 설계에 중요한 요인인 것이 밝혀졌다.
Many researches have been done to see if hypermedia training material is much more effective than the traditional training material. Only a few studies, however, on how to design effective hypermedia material have been performed so far. So this study would like to show the implications of the number of hyperlink and the size of node on the users' perceived usefulness and perceived easy of use on hypermedia training material. Six hypermedia training materials developed by 2×3 factorial design which has 6 combinations of each treatment level were used for experiments for the study After checking out the validity and reliability by factor analysis and Cronbach's alpha coefficients, statistical analysis has been done to test hypotheses of the study Multivariate analysis of variance (MANOVA) test was first done, because correlations among the survey items were found, and then univariate analysis of variance (Univariate ANOVA) test were performed to figure out the implications of treatment variables on a dependent variable. Multivariate analysis of co-variance (MANCOVA) and analysis of co-variance (ANCOVA) were tested, because the correlations between demographic data and one of dependent variables were found. Finally, experiment participants' preference was figured out by using the difference analysis of average. The result of the study showed the impotance of the basic components, hyperlink and node, of hypermedia training material for more efficient design.
