基于用户满意度的电子教学系统多指标评估方法

摘要

基于互联网的电子教学系统已成为技能培训与知识获取的一种新方法.在人机交互和多指标决策理论的基础上,从用户满意度的角度提出了一种多指标评估方法.通过实证调查得到初学者对决策准则相对重要性的理解,生成学习者综合偏好结构作为评估根据.研究表明,初学者将学习界面看作是决策准则中最重要的方面.%The web - based e - learning system has emerged as a new means of skill training and knowledge acquisition.Based on the theory of multi - criteria decision making and the research products of user satisfaction from the fields of human - computer interaction and information systems, this study proposes a multi - criteria methodology from the perspective of learner satisfaction to support those evaluation - based activities taking place at the pre - and post - adoption phases of the web - based e - learning system life cycle. This investigation carried out a survey of college students, and it then analyzes the data thus obtained by analytic hierarchy process in order to derive an integrated preference structure of learners as a ground for evaluation. We find that learners regard the learner interface as being the most important dimension of decision criteria.
