Abstract
Progress in the field of e-learning has been slow, with related problems mainly associated with the poor design of e-learning systems. Moreover, because of a depreciated importance of usability, usability studies are not very frequent. This paper reports the experience with the usability assessment of intelligent learning and teaching systems which are based on TEx-Sys model and are intended to enhance the process of knowledge acquisition in daily classroom settings. The applied scenario-based usability evaluation, as a combination of behaviour and opinion based measurements, enabled to quantify usability in terms of users’ (teachers’ and students’) performance and satisfaction. According to the achieved results, the main directions for interface redesign are offered. The acquired experience indicates that useful usability assessments with a significant identification of interface limitations can be performed quite easily and quickly. On the other hand, it raised a series of questions which, in order to be clarified, require further comprehensive research, the more so if the employment of universal design within e-learning context is considered.
