Learning management systems (LMSs) are increasingly popular in education. The usability of these
systems must be examined to ensure they meet the needs of both students and faculty. To address the
limitations of existing models for evaluating the usability of LMS, this research proposes a new model that
combines objective measures collected from eye-tracking with subjective measures collected from
retrospective think-aloud protocols and questionnaires. This model evaluates the effectiveness, efficiency,
satisfaction, and learnability of LMSs. The proposed model was applied to study the usability of the LMS
used at King Saud University (Blackboard) and was compared with other existing usability evaluation
models. The findings indicate that the proposed model fulfilled its intended purpose and provided more
comprehensive results than existing models.
