The evolution of mobile technologies gives the opportunity for innovative approaches to the content, the process and the evaluation of the educational activity. In this paper we study the particular situation where learner (student) is in displacement, in various conditions (walking in the rain, driving a car, riding a bicycle etc.), and receives the educational content through his or her smart mobile devices. Such a dynamic educational process, that we call mobile learning, presents many new aspects to study. We focus on the study of the interaction of the student with the educational process, running under various influencing factors and restrictions. In particular, the research carried out on Greek students who are learning Russian language. © Springer International Publishing AG 2017.
