Adults are adapting to new technologies with certain obstacles and difficulties in their professional context and especially in the area of their learning. Digital literacy for adults allows them to include themselves and take advantage of technology in their daily life. Evaluation instruments have been made to measure the level of digital literacy; however, a study on the impact of the level of digital literacy of adults in the context of learning virtual environments is required, specifically the xMOOC.
