“…Moreover, the influence of students' behavior while seeking for information in a LMS on their SUS rating will be investigated, using eye-tracking equipment and the theoretical foundations of information foraging theory (Katsanos, Tselios, & Avouris, 2010;Tselios Katsanos, Kahrimanis, & Avouris, 2007). Finally, the reliability of the SUS questionnaire compared within LMSs with other questionnaires measuring usability, such as SUMI, CSUQ, and QUIS, requires further examination.…”

Perceived usability affects greatly student's learning effectiveness and overall learning experience, and thus is an important requirement of educational software. The System Usability Scale (SUS) is a well-researched and widely used questionnaire for perceived usability evaluation. However, surprisingly few studies have used SUS to evaluate the perceived usability of learning management systems (LMSs). This paper presents an empirical evaluation of the SUS questionnaire in the context of LMSs' perceived usability evaluation. Eleven studies involving 769 students were conducted, in which participants evaluated the usability of two LMSs (eClass and Moodle) used within courses of their curriculum. It was found that the perceived usability of the evaluated LMSs is at a satisfactory level (mean SUS score 76.27). Analysis of the results also demonstrated the validity and reliability of SUS for LMSs' evaluation, and that it remains robust even for small sample sizes. Moreover, the following SUS attributes were investigated in the context of LMSs evaluation: gender, age, prior experience with the LMS, Internet self-efficacy, attitude towards the Internet and usage frequency of the LMS.
