A case study of usability testing on an asynchronous e-Learning platform

An effective and efficient e-learning platform should hide systems´ complexity and provide an easy and flexible interaction operation. Poor interface design of e-learning platform is a main factor impacting on students´ interactive with system and learning outcomes. The purpose of this study is to evaluate a non-degree e-learning platform with performance analysis and user perception methods to investigate the system´s efficiency, effectiveness and satisfaction. In this study, efficiency and effectiveness are evaluated by time on task and task completion score. Satisfaction is evaluated by questionnaire and participants´ feedback. Based on these data, this article analyzed the main interface design problem that frustrate learners and distract them from learning task, and given some advice for interface design in e-learning platform.
