Resumen
The sudden transition from face-to-face education to remote education under the international-level restrictions imposed as a result of the COVID-19 pandemic?a transition made in the spirit of achieving and developing accessible education?involved the application of methodologically diverse resources and strategies. The objective of this article is to investigate the digital resources that have been applied in higher education institutions, paying special attention to the type and frequency of use of resources. A literature review was carried out on a total of 44 articles. The main results show that the primary resources applied in higher education institutions were videoconferencing tools, educational videos, and virtual platforms. Most higher education institutions made use of free and open access resources. Our primary conclusions posit our observation that the use of digital resources for teaching in an emergency context has not enabled reflection on their use. Such reflection would equip institutions for the optimization of these resources toward their efficient pedagogical application in teaching?learning processes.
