“…This phase focused on formalizing the learners' needs and preferences, together with the properties of the educational resources, in an ontology in order to provide a standard representation and allow reuse of these concepts. In our previous research [2], we reviewed the state of the art and selected the most relevant specifications and guidelines to built our AccessibleOCW ontology [3]. The ontology provides a structured schema for defining the metadata of the learner's profile and the educational resources.…”

“…In our previous work [2], we reviewed and classified the state of the art, and identified the most relevant standards related to web accessibility in e-learning contexts. We analyzed 11 web accessibility standards, guidelines, and techniques, and examined 20 ontologies that are available in the literature and on the web.…”

“…Designing one system that meets the needs of all learners is usually not possible, as learners have different needs and preferences, in particular disabled learners. In a recent survey we conducted [2], we found that there is still no comprehensive formal representation of learners with disabilities and their particular accessibility needs in e-learning contexts.…”

OpenCourseWare (OCW) systems have been established to provide open educational resources that are accessible by anyone, including learners with special accessibility needs and preferences. We need to find a formal and interoperable way to describe these preferences in order to use them in OCW systems and retrieve relevant educational resources. This formal representation should use standard accessibility definitions of OCW that can be reused by other OCW systems to represent accessibility concepts. In this article, we present an ontology to represent the accessibility needs of learners with respect to the IMS AfA specifications. The ontology definitions together with rule-based queries are used to retrieve relevant educational resources. Related to this, we developed a user interface component that enables users to create accessibility profiles representing their individual needs and preferences based on our ontology. We evaluated the approach with five examples profiles.

“…The rapid development of information and communication technology has encouraged open and free education movement around the world (Abelson, 2008) is known in various countries as open education (which includes open resources, tools, and practices and shared frameworks to improve education access and effectiveness throughout the world). The movements (Elias et al, 2016;Johansen & Wiley, 2011) have encouraged the realization of equal rights to achieve quality education for all people (Rohs & Ganz, 2015). OCW enables lecture materials to be accessed freely and without any cost (Barrett et al, 2009).…”

“…The basic principle of OCW is that knowledge is a human product that can be distributed freely and used for various purposes for all levels of society in the world, including persons with disabilities (Elias et al, 2016;Johansen & Wiley, 2011;Guo et al, 2015). Although OCW was said to be initiated in 1999 (Abelson, 2008) in Germany when the University of Tubingen published certain lecture videos, it was formally introduced first by the Massachusetts Institute of Technology (MIT) in 2001 (Abelson, 2008;Barrett et al, 2009).…”

This paper aims to summarize and analyze the Developing Information Technology in Open CourseWare (OCW) movements and new opportunities in Asia in the context of supporting the education process in higher education that is in accordance with the recent demands for graduate competency supported by IT innovation. The review method is carried out in 3 stages: searching and downloading articles, filtering and sorting, and final screening. The results of this review show that the OCW movement in Asia is growing rapidly, among others, due to IT innovation, stakeholder commitment, public awareness, and the need for quality teaching materials. In the era of web 5.0 technology, lecturers must have the competencies to develop electronic activities through the Web that make students truly active so that online learning actually takes place rather than the electronic reading process. The impact of IT innovation has brought drastic changes in the field of education in the learning process has become an effective driving tool for improving learning outcomes and achieving educational goals, one of the most recent innovations is OCW. OCW movement in Asia has progressed rapidly and significantly, although they experience transformations in accordance with technological developments and needs in the field.
