Do you use mother tongue in  classes which are bad or low when disciplinary  and grade concerned?i wonder so much because it changes according to the classes in my school.While i never use mother tongue in some of my classes as they are so interested in English,it is not possible not to use mother tongue in classes which are so bad when disciplinary and  grade concerned?i use  kinds of materials during my lessons  like powerpoints,flashcards,realia etc. but there is no way to take their attention and make them understand if i don �t use mother tongue because  they don �t know even the elementary subjects alhough they are 8th grade students.
