In addition to a high technical level and performance in their discipline, engineers of the 21st century require a high level of general or transferable skills that allow them to excel in their work environment. Engineers at the University of Antioquia in Colombia are no strangers to this situation, which is why the University has decided to face this new condition through the inclusion of activities in courses that support the development of these skills. Part of these activities includes the transformation of the traditional evaluation scheme for Radiofrequency Circuits course in Electrical and Telecommunication Engineering programs. This transformation is been performed taking advantage of the LMS (Learning Management Systems) platforms, web and mobile application and game-based learning techniques. The development of innovative practices that can leverage information and communication technologies is one of the major challenges in education. This paper shows the design of an online game-based assessment and training strategy. The new assessment and training tests were designed to help students improve their learning outcomes on the course topics; meanwhile, they promote development of general or transferable skills such as the ability to solve problems in complex situations and working under pressure.
