As a teacher, you are often entirely on your own when it comes to instruction and you constantly have to make choices. Which exercise am I going to use? Should I have the students work in groups or not? How should I introduce this topic? Can I think of an interesting approach to motivate my students? To help you tackle these common teaching issues, we have launched a series of NT2-Cahiers: small, convenient guides that help you increase your professionalism and improve your NT2 lessons. These exercise books are written in such a way that they can easily be translated into practice.
