Abstract

Purpose Usability is one of the key concerns in the development of mobile learning applications. The aim of this paper is to design and validate a usability evaluation questionnaire (UEQ) for mobile learning applications. Design/methodology/approach The UEQ was developed in four stages: selecting primary studies and extracting usability problems, thematic analysis, creating UEQ items and validation and reliability using confirmatory factor analysis (CFA). Findings CFA to derive the model fit was computed using AMOS to test the construct validity. The model-fit values were within their respective expected acceptance levels. To assess the reliability of the instrument item loadings, the internal consistency coefficients such as Cronbach’s alpha, McDonald’s Omega and composite reliability were considered. Indicator loadings ranged between 0.735 and 0.933, fulfilling the threshold of above 0.7. Originality/value The study provides a novel UEQ for mobile learning applications, which can be used by developers and in academic research to assess mobile learning applications.

移动学习应用可用性评估问卷（UEQ）的设计与验证

目的可用性是开发移动学习应用程序的关键问题之一。本文旨在为移动学习应用设计并验证可用性评估问卷（UEQ）。设计/方法/途径UEQ的开发分为四个阶段：选择主要研究并提取可用性问题、主题分析、创建UEQ项目以及使用确认性因子分析（CFA）进行验证和可靠性测试。模型拟合值在各自的预期接受水平之内。为了评估工具项目负荷的可靠性，考虑了内部一致性系数，如 Cronbach'sα、McDonald's Omega 和综合可靠性。指标负荷介于 0.735 和 0.933 之间，达到了 0.7 以上的临界值。原创性/价值该研究为移动学习应用提供了一个新颖的 UEQ，可供开发人员和学术研究人员用于评估移动学习应用。

期刊介绍： Interactive Technology and Smart Education (ITSE) is a multi-disciplinary, peer-reviewed journal, which provides a distinct forum to specially promote innovation and participative research approaches. The following terms are defined, as used in the context of this journal: -Interactive Technology refers to all forms of digital technology, as described above, emphasizing innovation and human-/user-centred approaches. -Smart Education "SMART" is used as an acronym that refers to interactive technology that offers a more flexible and tailored approach to meet diverse individual requirements by being “Sensitive, Manageable, Adaptable, Responsive and Timely” to educators’ pedagogical strategies and learners’ educational and social needs’. -Articles are invited that explore innovative use of educational technologies that advance interactive technology in general and its applications in education in particular. The journal aims to bridge gaps in the field by promoting design research, action research, and continuous evaluation as an integral part of the development cycle of usable solutions/systems.
