At the University of Seville, the participants will be 3rd–year students of the Degree in Software Engineering. We expect the number of participants to be around 150–200.v At the University of California Berkeley, the participants will be students enrolled in the 1st and 2nd semester Computer Science courses. In this case, we expect the number of participants to be around 100–300.
