One portion that needs to be considered is the students nationality and their culture. If the teacher understands the students culture (Lets say a foreign student) then they increase there ability to connect with the student. For instance in Korea it is customary to hand something to a person, using both hands. Usually one hand holds the object and the other hand is touching the arm of the hand holding the object as the object is extend to the receiver. If you reciprocates the behavior you quickly build rapport with that person. This action by you communicates you respect his/her culture which is an important matter to them.
