[1]Peer tutoring benefits many students in several ways. Peer tutors can help themselves in

understanding materials. They have to master the material themselves and come to a deeper

understanding to teach others rather than getting taught by a teacher.

[2]Peer tutors get communication and social skills by tutoring. In order to communicate the meaning

of material clearly and make it understood, they must practice the necessary skills to communicate with

other people. These skills also carry over socially as it's much easier, especially for shy children to

communicate with someone than to communicate with a large group as in a classroom. It's common for

the tutor and his student to become friends. Developing leadership skills, confidence and a sense of

responsibility is easy for a tutor. The tutor becomes a better student, gains more confidence and

understands the teacher's role better.

[3]Those ___________ can also benefit greatly from peer tutoring. Since the tutors are of the same

age as the students, it's more comfortable for the children who have trouble with the material and in need

of help to get taught by the same age tutors. This will allow them to ask more questions without fear and

to come to a better understanding of the material. The tutor may be able to pass on little tips and tricks

that helped him understand the material better.

[4]The process of peer tutoring works for all the related people. It's easy to relate to someone of the

same age. The tutor learns to improve skills useful later in life. The teacher has more time to concentrate

on students. It's a winning situation for everyone.
