Every people agree with the importance of knowing English nowadays. This language has become the “lingua franca” and it is taught all over the world. Students from every country learn English at school. And some of them achieve a good level. But being plurilingual is more than this.
“Language learning is a lifelong task” as the Council of Europe says. People should face new language experience out of school. Because of that, the aim is to develop a linguistic repertory in which all linguistic abilities have a place.
You can speak one or more foreign language, but if you keep them in strictly separated mental communicative compartments, you will not be plurilingual.
Therefore, it’s important to use different languages at school to acquire contents in order to achieve effective plurilingualism. And CLIL methodology provides interesting activities that help teachers and students in this goal.
