It is a common belief that engagement and motivation are crucial factors in learning and especially in language learning. In particular, increasing motivation can lead to the mobilization of students' personal, cognitive, emotional and behavioral resources and, consequently to better learning results. As digital technology has become more sophisticated, its tools and applications can be used in and outside the classroom, in both formal and informal settings, in order to increase students' motivation. Amongst the various factors -tools, methods or strategies- that can lead to increased motivation, this paper examines the role of technology as a motivational factor in foreign language learning. The relationship between the use of technological means such as web tools and services, digital games, mobile apps or communication tools and motivation in language learning context, has been studied extensively, with a wide variety of approaches, and within the framework of several language learning applications. In order to determine the real impact of technology on learners' motivation, an extensive literature review focusing on studies that have examined the impact of technology use in language learning and teaching on motivation to learn, has been carried out. Furthermore, this paper discusses the concept of motivation in learning context and the relationship between technology and language learning, summarizes some of the numerous studies and researches on this subject, presents a synthesis of the studies examined, and formulates conclusions and perspectives for effective integration of technology as a motivational tool / factor in language learning context.
