A good topic to work on in the three languages students learn. Maybe a bit tiresome if they have to do the same in the three languages. Investigation and research to encourage students´autonomy and learn to learn competence as well as team work and peer-evaluation are good aspects, among others, in this teaching sequence.Remember these sequences are not apart from the curriculum of the subjects; so whenever we plan to design a interdisciplinary work we have to focus on the subjects curricula participating on it. Good job!!
