The socialization of P. E. pre - service teachers is under the common influence of“pre - experience”and early inter- personal interaction. P. E. pre - service teachers constantly develop“teaching orientation”to overcome“training orientation”,con- stantly innovate their beliefs about P. E. teaching,and constantly internalize the values,role expectations and behavior norms related to P. E. teachersto form and show the appropriate role behavior process. According to the theory of professional socialization,it includes three stages: ( 1) expected socialization with subjective feelings and apprenticeship observation; ( 2) professional socialization with subject knowledge and teaching behavior acquisition; ( 3) organizational socialization with the establishment of professional identity. In this process,pre - experience,curriculum learning and practical experience,socialized subject,interpersonal interaction and organiza- tional culture situation constitute the development motivation of different stages,which makes the normal students of physical education gradually change from“ordinary sports people”to“qualified physical education teachers”.
