High Expectations

I think teachers should have high expectations about their students.
Students can deliver as much as you ask them to do, if you create high expectations and you expect them to deliver they will feel confident and will learn to trust themselves and believe that they can do it. I have seen students whose teachers don't believe in them and they are not confident and think that they can not do a satisfactory job. I have also had teachers myself who do not think we can do a good job and it shows.
Having high expectations helps the teacher and help the students. You can have a better communication and a better relationship.
You can do it! it is a great phrase.
