Evaluating and Testing User Interfaces for E-Learning System: Blackboard Usability Testing
AbstractE-learning usability studies require the involvement of real end-users. Different users with varying background of Human Computer Interaction (HCI) knowledge behave differently when using any e-learning tools. To study user behaviour in the e-learning context, an empirical usability study on a specific e-learning tool is conducted. The study is performed by using usability evaluation questionnaires collected from two different groups of real users of the tool; one group with HCI knowledge and the other without HCI knowledge. It is found that end users without HCI knowledge are more satisfied than the end-users with HCI knowledge, as they have more expectations concerning the tool.
