摘要

本文的目的是改进现有的系统可用性量表(SUS),并评估其在学习管理系统(LMS)中的适用性。在当今的市场中,评估系统可用性的需求变得越来越重要,因为它可能对用户体验产生重大影响。鉴于2019冠状病毒病大流行,电子学习已成为学生的重要工具,使LMS成为合适的研究案例。通过全面的文献回顾,我们发现SUS是评估系统可用性最广泛使用的工具。然而,SUS未能满足ISO 9126和ISO 9241-11中概述的一些可用性标准。因此,本文提出了一个增强的SUS模型及其概念框架来解决这些限制。使用案例研究方法验证了所提出的模型,涉及主题专家和软件测试学生,他们评估了增强型SUS的可靠性。此外,基于LMS案例研究对现有SUS模型和增强型SUS模型进行评估,并使用Cronbach's alpha计算增强型SUS的信度系数。验证结果表明,与原始SUS相比,增强SUS具有更高的可靠性和更高的质量覆盖率。所提出的模型有可能增强对系统可用性的评估,从而改善用户体验。

Enhanced System Usability Scale using the Software Quality Standard Approach
The objective of this paper is to improve the current System Usability Scale (SUS) and assess its applicability in the context of Learning Management Systems (LMS). The need to evaluate the usability of systems has become increasingly important in today's market, as it can have a significant impact on the user experience. In light of the COVID-19 pandemic, e-learning has become an essential tool for students, making LMS an appropriate research case study. Through a comprehensive literature review, it was discovered that SUS is the most widely used tool for evaluating system usability. However, SUS fails to satisfy some of the usability criteria outlined in ISO 9126 and ISO 9241-11. Therefore, this paper proposes an enhanced SUS model and its conceptual framework to address these limitations. The proposed model was validated using a case study approach, involving subject matter experts and software testing students, who evaluated the reliability of the enhanced SUS. Additionally, the existing and enhanced SUS models were evaluated based on an LMS case study and the results were used to calculate the enhanced SUS's reliability coefficient using Cronbach's alpha. The validation results show that the enhanced SUS has higher reliability with improved quality coverage compared to the original SUS. The proposed model has the potential to enhance the evaluation of system usability and, consequently, improve user experience.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
