Developed heuristics evaluations of related multimedia based application were thoroughly analyzed based on specific criteria being used in the heuristics. As a conclusion, Heuristics Evaluation for Courseware (HECW) was proposed to be developed because of the important elements of courseware that need to be addressed in order to develop a usable and acceptable courseware. Keywords Heuristics Evaluation; Heuristics Evaluation for Courseware; Usability; Courseware 1. Introduction Usability is a one of the main and core concepts that have emerged from the human–computer interaction (HCI) field. There are various definitions of usability, amongst them are ‘‘the capability to be used by humans easily and effectively’’ (Shackel, 1991), ‘‘quality in use’’ (Bevan, 1995) and ‘‘the effectiveness, efficiency, and satisfaction with which specified users can achieve goals in particular environments’’ (ISO., 1998). Widely used definition of usability is based on definition by International Organization for Standardization (ISO) “the extent to which the product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use” (ISO., 1998). Based on various definitions, researchers have developed various technique and criteria to evaluate usability and one of the commonly use technique is Heuristic Evaluation (HE). HE is a discount evaluation method commonly used to find usability problems at different development stages of a product. Heuristics are design guidelines which serve as a useful evaluation tool for both product designers and usability professionals (J. Nielsen, 1994). In the software productivity industry, heuristics have typically been used to evaluate the usability of interfaces (J. Nielsen, 1994). Heuristic evaluation involves a small number of evaluators inspecting a system according to heuristics or guidelines that are relevant for the system. Heuristic evaluation is a light-weight process that can be cheap, fast, and easy to apply in evaluation process. It can be used both in design and evaluation phases of development and can even be applied to paper-based designs before the first working prototype is created. HCI studies showed that using five evaluators
