“…The results showed that the Greek SUS questionnaire does not include any reliable subscales. Thus, all statements form a single reliable scale that measures perceived usability, a finding consistent with our previous research (Katsanos et al, 2012).…”

“…For the dataset of 436 completed surveys, the 10-item Greek SUS questionnaire had a good internal consistency; Cronbach's alpha=0.808. In our previous research (Katsanos et al, 2012) the value of Cronbach's alpha for the Greek version of SUS was slightly lower; α=0.777.…”

“…Participants were presented with either the Greek (Katsanos, Tselios, & Xenos, 2012) or the English (original) version of the SUS items based on their self-rated knowledge of English. We provided this option in an attempt to minimize potential threats to the validity and reliability of SUS data obtained from non-native English speakers (Finstad, 2006).…”

“…We provided this option in an attempt to minimize potential threats to the validity and reliability of SUS data obtained from non-native English speakers (Finstad, 2006). In our previous research (Katsanos et al, 2012), three studies involving 280 university students in both blended and distance learning education were conducted. Analysis of the results demonstrated the validity and reliability of the Greek version of SUS in the context of Moodle evaluation.…”

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.
