Mobile learning has been used at Corvinus University of Budapest since the late 1990s. Approximately 3000 students use mobile academic content each year. A focus course in 2007 provided lecture notes, tests, and questionnaires to over 650 students via mobile devices. A survey found that students believe mobile learning increases e-learning quality, though many cited issues with small screen sizes and slow navigation. Recommendations included keeping content small in size and simple to access, providing more audio content, and improving design and promotion of the mobile learning system.
