We second or foreign language teachers should promote and train our students to gain a communicative competence in that language. We do not confine our teaching to language facts. No, we train our dear students for a communicative competence.
That said, focus on providing a massive output from you, for your students to have and receive a massive input and intake. If no input and intake, no language. And for that I advise you to teach at the communicative approach: communication, communication, communication.
Not many language facts but communication in the classroom. So immersion will be fine for our students.
Please pray for us Spanish people, for yesterday August 17 we suffered a big terror attack in Barcelona. Thank you! / Photo from: history-teacher All Education School
