Facing a new group of students

When I start teaching a group of adolescents for the first time, I try to make them feel confident with the language by assigning them activities that follow a communicative purpose.
Language must be presented as a tool that links second language with their own world. The idea of introducing themselves for the first time is a good activity to be carried out since they have the opportunity to use second language as well as the use of simple sentences through questions such as: "May I go to....?" or "what's the English for", will encourage the learners to use L2.
As teachers our main aim is to allow learners to become better communicators.

Motivation play a crucial role in the development of the class, since it helps students to lower their affective filter and feel confident with the language. It's the teacher's ability to select different learning strategies in order to encourage the learners to adopt a different attitude towards a second language.
