Global corporations are characterized by a large number of employees and geographically dispersed offices. Moreover, the competitiveness in the global market requires them to invest in their human resources to be able to remain a step ahead of the competition. Implementing large scale classical education in such environments is challenging and costly. Mobile e-learning allows users to tailor their professional education to their needs and time constraints. However, in self-paced education it is very hard to keep user retention and engagement. To achieve the latter we have designed and developed a mobile e-learning platform for corporate environments based on the persuasion and/or gamification design guidelines that try to incite users in regularly using the platform. We have evaluated the application in-the-wild in corporate environments of differently sized companies. The results show that the use of persuasive technologies in mobile learning increases user engagement as well as course completion rates.
