Generally, people are motivated by language teachers should concentrate on analysis positive feedback to their students when they do superb work, rather than on criticizing disappoint work. Some people might believe that teachers must give positive feedback to students when they do well work, while others might criticizing bad work it is a good way for children. However, in my opinion, I partly agree with these two topics because all of student need superb advise when they do a great thing and always need to recommend what is wrong with their work.
