. Do you think it is best to avoid errors in class?
No I don´t . I think is better that they finish their activities with freedom and not interrupt until the class finish and in group check the activities and possible mistakes and they correct them.
. Which of the ideas (in exercise 5) have you tried yourself?
the ideas from the teacher A. when my students are talking for example. in a role play I prefer no to interrupt them but when they finish I write and tell to the students their mistakes that they had to correct.
