Abstract
Learning Management Systems (LMS) have been widely adopted in many higher educational institutions to support teaching and learning activities. The study was conducted with the aim of investigating the usability of the learning management system (Blackboard) at Jeddah Community College (JCC) from the students' perception, using a System Usability Scale (SUS) survey. The study examined the association between SUS scores and different variables: age, prior experience with LMS, ICT skills, attitude towards the Internet and LMS usage frequency. All participants were students at JCC. The online survey was sent by email to students who were enrolled in Information Technology (IT) courses during the 2016 summer semester. 50 responses were received and used for data analysis. The findings indicate that the overall mean of SUS score is 69.3 (SD 11.31), indicating that the current LMS has some usability issues. It was also found that the students' LMS usage frequency is positively correlated with their SUS score. The findings can be used to consider the effectiveness of LMSs.
