Conceptual design and development model of assistive courseware for young low vision learners (AC4LV)

The focus of this study relates to technology (hardware and software) that is purposely designed for people with disabilities (PWDs), which is called Assistive Technology (AT). Previous findings reveal that studies related to educational content in courseware is highly lacking, particularly for low vision learners. Also, many existing conceptual design models of courseware lack of specific requirements and empirical evidences to cater the needs of low vision learners. Preliminary studies have proven that available content applications fail to cater the needs of low vision learners in terms of information accessibility, navigationability, and pleasurability. Hence, this study proposes a conceptual design model of courseware for low vision learners, named as Assistive Courseware for Low Vision (AC4LV). Four (4) specific objectives are formulated. The Design Science Research Methodology has been adopted. Eight (8) components of Conceptual Design Model of
AC4LV have been constructed and integrated: structural, content composition, AC4LV element, learning theories, learning approaches, development process, instructional design model, and technology. The proposed model has been reviewed by 12 experts and validated through prototyping. It was found that the proposed model has been well-accepted by local and international experts. Prototyping has implicated that the model is useful to follow by novice and non-technical developers. On top of that, the findings of user experience testing indicate that the AC4LV is able to fulfill the needs of the low vision learners in terms of
information accessibility, navigationability, and pleasurability. All these findings demonstrate that the Conceptual Design Model of AC4LV exhibits useful development for content application as well as providing theoretical and practical contributions of the study.This study provides guidelines for developing educational content in courseware that caters the need of low vision learners so that this particular group of PWDs may gain equal opportunities of learning.
