本文以学习需求理论为基础,运用产品质量功能展开(QFD)的方法,探索了学习需求导向的数字语言学习系统的质量特性,为系统的研发设计和质量改进提供有益参考。文章从目标需求和学习需求两个维度进行系统质量需求转化,得到系统基本质量特性,进而根据特性的相关性进行聚类分析,形成系统主要质量特性和质量特性需求金字塔。
Based on the theory of learning needs, this paper explores the quality characteristics of learning-oriented digital language learning system by using the method of product quality function expansion (QFD), which provides a useful reference for system development and design and quality improvement. The article transforms the system quality requirements from the two dimensions of the target demand and the learning demand to obtain the basic quality characteristics of the system, and then carries out the cluster analysis according to the correlation of the characteristics to form the demand pyramid of the main quality characteristics and quality characteristics of the system.
