Do you think it is best to avoid errors in class?

[CARES]

Well, in my opinion it is impossible to avoid students making errors in class, so I believe that teachers should take advantage of these errors and use them. We could use real students’ mistakes by showing them to students o the blackboard and making students try to find what the problem is with these mistakes. It is interesting sometimes to see students correcting their own mistakes after having been given some grammatical input.
