个性化语言学习系统质量特性的提取与定位

Extraction and Position Research on Quality Characteristics of Personalized Language Learning System

Under the design concept of “user centered”， the extraction and position of quality characteristics that users’ need is the success foundation of product design. Focusing on the “learners' needs”， the quality characteristics of personalized language learning system are extracted and positioned by using the theory and method of quality function deployment (QFD) and Kano model， so to provide benefit reference for the improvement of design quality of system. Firstly， the quality characteristics are extracted and converted from the learners’ original require by QFD， which covered three aspects as learning resource， process and environment， and all about 22 items. Then， the importance of quality characteristic was investigated in the case of public English Learners. According to the level of importance of the survey， the quality characteristics are divided into three categories as very important， more important and generally important. Finally， according to the distribution of importance degree scatter diagram， the quality characteristics are further positioned from three levels of charismatic quality， expected quality， and must be quality， combining with the Kano model. Though the identification and double positioning of the quality characteristics that learner's needs， the design quality’s accuracy and scientificity of the personalized language learning system were improved， and it is convenient for enterprises to determine the key point of system design according to their own conditions， and to make rational allocate and optimize resources.
