hi dear colleagues . here is a way to make students talk shown below:
pretend you area student who :
 
1) keep complaing a bout everything 
2) is unable what to do witha new word
3) hesitate unnecessarily alot while talking.
4) is afraid of producing speech because of her/his partner
5) can �t find an appropriate grammatical material
and..........
 
just be like a stduent to make them understand how they would like while being asked to talk. i personally tried this way and it worked!!!!!!!
 
WOULD YOU LIKE SOME MORE WAYS???
