چکیده
Usability evaluation is a critical part in an application development process and currently there are many techniques which have been developed by HCI researchers in the usability evaluation of a system. One of the commonly used techniques in evaluating usability is Heuristic Evaluation (HE). In this research, the courseware had been evaluated based on HECW which contains 4 main heuristics; Interface, Educational Elements, Content and Additional Elements. The data collected were analyzed based on a quantitative approach known as Usability of HECW (UsabHECW). UsabHeCW is a function to calculate the total percentage of the courseware usability. Based on the usability analysis, the critical usability for the courseware in each category had been determined. The analysis had been able to identify which sections of the courseware are critically to be corrected and improved. The usability analysis which is based on UsabHeCW has proven to be a reliable technique in identifying usability problems for the courseware. The presentation of result in the form of percentage is a distinctive result from this analysis, while the process of analyzing usability problem could be done faster.

متن کاملLearning technology and usability: a framework for understanding courseware
This paper argues that the usability of educational software cannot be measured in the same terms as other work contexts. This is because learning is a by-product of understanding rather than an activity which can be supported directly. Although it is best achieved through the performance of meaningful tasks, these tasks need to be designed to support different kinds of learning. We approach th...
