Which of the ideas (in exercise 5) have you tried yourself?
I have tried not to interrupt fluency activities.
Do you believe it is important not to interrupt students when they are speaking in order to draw attention to their errors?
Yes, I do believe that it is crucially important not to interrupt students during their speaking. Moreover, it is a good idea show interest, maybe ask follow-up questions in order to encourage students to speak more and make them feel comfortable with a delayed correction of mistakes.
