We say in Spanish about the fact that the teacher of English “tiene que ponerse en juego a sí mismo del todo”, which means that the teacher must invest his best efforts and creativity while teaching the class, and when planning the class.
He’s the main source, the main activity source, plus he must have clear that he doesn’t teach English but he helps his students to learn English or any other modern language.
He’s a booster.
This is not opposite to the idea for example of making a presentation, sometimes presenting a verbal tense… Other times he will teach a verbal tense in a more naturalistic way. / Photo from: irish-mirror-tipperary-kilkenny guaranteedanmarie com. playing hurling, an Irish game
