ARCHUNDIA SIERRA, Etelvina  y  CERON GARNICA, Carmen. Digital Learning Objects for people with visual disabilities in data structures: graphs (OAGRAF). RIDE. Rev. Iberoam. Investig. Desarro. Educ [online]. 2018, vol.8, n.16, pp.289-310. ISSN 2007-7467.  https://doi.org/10.23913/ride.v8i16.342.

The ADDIE method integrated by the phases of: analysis, design, development, implementation and evaluation; and the proposal that integrates the instructional model of the four components (Model 4C / ID) in the Learning Objects (OA) for the data structures: graphs and the Dijksta´s algorithm; In addition to using elements that allow the people with visual disabilities to enter the study of computer discipline in higher education through multimedia resources. The work shows a prototype of OA implemented in the MOODLE virtual platform, using multimedia resource and the eXeLearning tool that will allow students in Computer Science, identifying the necessary elements in the Dijkstra algorithm and its application in an alternative of learning through the use of technology. The usability tests in terms of ease of use, identification of elements and types of graphs, were considered between very good and excellent, and the ease of applying the algorithm of Dijkstra obtained a good in the way.
