Blended intensive programs, within the framework of the Erasmus+ Program, promote collaboration between partner universities to create an academic program that combines virtual collaborative teaching/learning among students from these universities with a short-term face-to-face mobility period. Programs may include challenge-based learning, in which transnational and transdisciplinary teams work together to solve challenges. These are short programs organized by a minimum of three European universities that employ an innovative methodology in the teaching-learning process. Blended intensive programs must include the recognition of a minimum of 3 ECTS credits, and group a minimum of 15 physically mobile participants.
