Usability evaluation is a key element to ensure a positive user experience with any software and it is especially important in educational software tools where there are many different actors involved (lecturers, students, administrators, etc.). However, evaluating usability is not an easy task for nonexpert evaluators. To facilitate this evaluation task, this article presents a Methodology for Usability Testing (MUT) and a system (CALMUT) that assists nonexpert evaluators in the application of the methodology by automatizing the calculations and facilitating their interpretation. This can be very useful for learning and instructional designers but also to people involved in the decision of introducing or not a new educational software. To develop the proposal, a literature review of different usability metrics, methods, and systems was carried out first, followed by a selection and adaptation for novice usability evaluators. This article also presents a case study where lecturers tested the usability of an educational software following the proposal and shows that using MUT and CALMUT helps people without previous experience detect the main usability problems of educational systems before deciding whether to use them or not.

促进和自动化教育技术的可用性测试

可用性评估是确保任何软件获得积极用户体验的关键要素，对于涉及许多不同参与者（讲师、学生、管理员等）的教育软件工具尤其重要。然而，对于非专业评估者来说，评估可用性并不是一件容易的事。为了促进这项评估任务，本文提出了一种可用性测试方法（MUT）和一个系统（CALMUT），该系统通过自动化计算并促进其解释来帮助非专家评估者应用该方法。这对于学习和教学设计者非常有用，对于参与决定是否引入新教育软件的人也非常有用。为了制定该提案，首先对不同的可用性指标、方法和系统进行了文献综述，然后对新手可用性评估人员进行了选择和调整。本文还介绍了一个案例研究，其中讲师根据提案测试了教育软件的可用性，并表明使用 MUT 和 CALMUT 可以帮助没有经验的人在决定是否使用教育系统之前检测到教育系统的主要可用性问题。
