This research deals with the development of global knowledge acquisition and the enhancement of 21st century communicative skills in English as a Foreign or International Language (EFL/ELF) through ubiquitous learning environments (ULE, u-learning) that occur anywhere and at any time. Through the use of ubiquitous mobile devices (m-learning) and digital information that can be accessed inside and outside the classroom, a contextualized ULE is designed in order to respond to the real and professional needs of higher education students. U-learning is supported by the adequate use of Information and Communication Technology (ICT), Open Access resources (OA), collaborative learning, independent learning and the combination of formal and informal learning to allow lifelong learners to generate multimedia knowledge and to debate, build and enhance their linguistic and communicative skills in the foreign language throughout their experiences (u-learner). This approach pursues the adaptation of the university student to the changing context of a 21st century professional citizen.
