Bilingual or plurilingual education models?

In my opinion the question is not whether one model is better than the other, but the results that we have obtained in Valencia after many years of Valencian CLIL. This educative system has been a complete disaster. In fact, students aren’t able to use neither Spanish nor Valencian language properly. That’s why the implementation of multilingualism will not give any different results. Why? Because the actors, resources and tools that are going to be used will be more or less the same that have been used for many years. The problem goes beyond languages. It is a social and political problem.
