Examining the effect of website complexity and task complexity in web-based learning management system

Nowadays, e-learning has been used widely as an indispensable tool for teaching and learning. One of the most popular types of e-learning is learning management system (LMS). Interface design of LMS plays a big role when users are interacting with LMS environment. Beside the interface design, the type of tasks performed by users also affects users, especially the learning experiences. This study examines the effects of website complexity and task complexity in web-based learning management system on users, particularly the perceived usability and user experience. Using SUS and UEQ, the results show that there is an inverted U relationship between LMS complexity and perceived usability and user experience. A negative relationship is also found between task complexity and perceived usability and user experience. Our findings provide guidelines for LMS designers, LMS developers and teachers when designing a LMS or a course in LMS. This study proves that overall LMS with medium complexity is better in terms of perceived usability and user experience compared with LMS with low and high complexity.
