New paradigm in evaluating usability of E-learning system

Most researchers and experts in human computer interaction (HCI) and e-learning areas evaluate the system usability primarily based on user interfaces without paying much attention to the content of the site; e.g. course content. However, according to available usability models, the two important criteria of usability include user satisfaction and learnability which the former is related directly to the content. Therefore, in e-learning environment, learners who primarily use e-learning system for their education will be satisfied not only by using a ldquousablerdquo interface but also a ldquousablerdquo content. The content usability defined based on some factors. These factors include technical issues, instructor capabilities, content interaction, pedagogical issues, and learner´s learning style.
