| dc.description.abstract | The use of technologies to support educational processes has allowed to be expanded the interaction and communication mechanisms, the incorporation of innovative learning environments and the possibility of greater access to teaching materials, such as the repositories of digital educational resources. One of the great challenges in these environments is to offer the customization of the platforms according to the needs and preferences of the students, achieving through the incorporation of adaptive strategies to respond automatically to their conditions. In addition, technologies are expected to contribute to the educational inclusion processes of people with disabilities. However, they can become a factor of exclusion due, among other things, to the lack of strategies to promote accessibility without knowing the diversity of the students. This thesis proposes a model for adaptive accessibility in repositories of digital educational resources, in which mechanisms that identify the needs and preferences of the student in terms of accessibility aspects are defined, so that adaptations can be made automatically in the website of the repository and educational resources, reducing barriers and applying the idea that it should serve all users recognizing the diversity of each one of them. The proposed model offers the possibility of making specifications, as in the case of the model for sensory diversity, which was validated through the implementation of a prototype, the performance of accessibility assessments and tests with users, obtaining favorable results indicating that effectively fulfills the proposed adaptive accessibility process. | spa |

Uno de los grandes retos en estos ambientes es ofrecer la personalización de las plataformas de acuerdo a las necesidades y preferencias de los estudiantes, logrando a través de la incorporación de estrategias adaptativas responder de forma automática a sus condiciones. Además, se espera que las tecnologías contribuyan a los procesos de inclusión educativa de las personas en situación de discapacidad. Sin embargo, pueden convertirse en un factor de exclusión debido, entre otras cosas, a la falta de estrategias para promover la accesibilidad desconociéndose la diversidad de los estudiantes. En esta tesis se propone un modelo para accesibilidad adaptativa en repositorios de recursos educativos digitales, en el cual se definen mecanismos que identifican las necesidades y preferencias del estudiante en cuanto a aspectos de accesibilidad, de tal manera que se puedan realizar adaptaciones de forma automática en el sitio web del repositorio y los recursos educativos, disminuyendo las barreras y aplicando la idea de que debe servir para todos los usuarios reconociendo la diversidad de cada uno de ellos. El modelo propuesto ofrece la posibilidad de hacer especificaciones, como el caso del modelo para diversidad sensorial, el cuál fue validado a través de la implementación de un prototipo, la realización de evaluaciones de accesibilidad y pruebas con usuarios, obteniendo resultados favorables que indican que se cumple efectivamente el proceso de accesibilidad adaptativa propuesto. | spa |
