Previous studies have found out that educational applications using the Augmented Reality (AR) technology have provided immersion, motivation, fun and high level of engagement. However, designing and developing of the AR courseware with these characteristics while ensuring the effectiveness in teaching and learning process can be quite challenging. The increasingly use of AR has called for the creation of more usable products of high quality, which in turn, makes the Usability Evaluation testing an essential process. Previous researchers stressed that until very recently, where the Usability Evaluation of AR interfaces had not been systematically examined. Furthermore, nowadays usability is a fundamental factor to consider when developing educational courseware. Therefore, a good design for the usability evaluation methodology is needed which is best suited for Down Syndrome (DS) learners in early reading. This paper describes the review of usability evaluation in learning courseware and presenting the usability evaluation that has been successfully applied to previous AR applications. Next, we will present several existing usability evaluation methods as a guideline in conducting the usability evaluation for AR BACA SindD. Lastly, this paper proposed a Design of Usability Evaluation Methodology Framework for AR BACA SindD, especially for the DS children in this case study. Hopefully, the methods that were used for the evaluation as well as the suitable usability evaluation methodology proposed, can be deployed to evaluate the effectiveness of the courseware to disabled children as general and primarily to the DS children.
