Good student－teacher relationships result from the choices that are made even before school, and how those choices are carried out on a daily basis. Here are a few tips to make this process easier for both parties.

_1.__

For the teacher, this means that they need to look at each student from the perspective(角度) of what that student could learn, rather than what that student learned last week or last year. For the student, this means that they need to enter the classroom every day with the willingness to trust the teacher to help them understand. __2.__ Every school day there are new opportunities to learn new information or to understand subjects that might have been difficult in the past.

__3.__

This is not to say that you have to “buy” the affections(關(guān)愛(ài)) of the student or the teacher，but you can give the gift of a smile，the gift of attention in class，or the gift of eye contact. Giving this type of gift always helps to build strong relationships.

Demand the best.

__4.__ We can trust friends to keep us responsible and when developing good student－teacher relationships，the same principle of trust applies. Setting high expectations always pushes us to be our best，and when both the student and the teacher are pushing the other for more depth, more wisdom, more insight, etc，then both the student and the teacher will give more.

To develop a good student－teacher relationship，both the student and the teacher must be willing to decide to do these things daily. Each day，they must be willing to try again and work on the relationship. _5.__

A．Buy gifts for teachers.

B．Give gifts to one another.

C．Focus on the positive.

D．We can always learn a lot from our teachers.

E．Future learning is never limited by past experiences.

F. Good relationships are always founded on honesty and high expectations.

G．The most important thing is to trust the relationship to benefit each of the members.
