Finally The advantages and disadvantages for the course book and the best use of it was very useful to know when and how to use it and with which level.In the lesson I learned that it is not beneficial to allow the use of the students native tongue in the classroom and that one of the benefits of a multilingual class is that in a lot of cases English may be the only common tongue between the class.
