The evidence and lack of a measurement consensus require the inclusion of contextual information, corroborating scientific results with practical experiences. For this reason, this article presents a review of accessibility models, OER and MOOC, considering the gray literature to capture experiences and trying to establish a shared understanding of the terminology commonly used in research on virtual accessibility and its impact on higher education. The bibliographic review relies on analyzing articles and scientific publications related to the topic following the Multivocal Literature Review (MLR) format. The results of this review establish that it is possible to apply accessibility review methodologies with transversal actions in the creation and management of learning resources and MOOCs. The research is related to one of the seventeen sustainable development goals defined by the United Nations to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all.<\/jats:p>","DOI":"10.3390\/su14063340","type":"journal-article","created":{"date-parts":[[2022,3,13]],"date-time":"2022-03-13T21:44:17Z","timestamp":1647207857000},"page":"3340","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Accessibility Challenges in OER and MOOC: MLR Analysis Considering the Pandemic Years"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3250-6156","authenticated-orcid":false,"given":"Paola","family":"Ingav\u00e9lez-Guerra","sequence":"first","affiliation":[{"name":"Research Group on Artificial Intelligence and Assistance Technology, Salesian Polytechnic University, Cuenca 010107, Ecuador"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7645-8793","authenticated-orcid":false,"given":"Vladimir","family":"Robles-Bykbaev","sequence":"additional","affiliation":[{"name":"Research Group on Artificial Intelligence and Assistance Technology, Salesian Polytechnic University, Cuenca 010107, Ecuador"}]},{"given":"Ant\u00f3nio","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Department of Education and Distance Learning, Universidade Aberta, 1269-001 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6417-1779","authenticated-orcid":false,"given":"Salvador","family":"Ot\u00f3n-Tortosa","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Polytechnic School, University of Alcal\u00e1, 28805 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9196-1031","authenticated-orcid":false,"given":"Jos\u00e9 Ram\u00f3n","family":"Hilera","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Polytechnic School, University of Alcal\u00e1, 28805 Madrid, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,12]]},"reference":[{"key":"ref_1","unstructured":"ONU (2022, February 20).
