Socialization is the process that begins at birth, lasts throughout the lifetime and has an influence that grows along with the individual. The most important agents of socialization include family, kindergarten and school, that all have a great influence on the child and its development. The socialization process in the family is under the influence of the parenting style, attachment and family status. The most important relationships in school are the ones with the teachers and peers; especially friendships with other peers and child's popularity among them. Social skills that are developed during the socialization process influence child's behavior at school and his achievement. Studies have shown that socialization has a positive effect on students' motivation and participation in school activities. Schools that understand the importance of socialization should continue to use teaching methods that encourage students' interaction and development of their social skills.
