It is noted that the academic-oriented tradition of university has largely reflected on its vocational programs including a teacher training program from the beginning. The vocational program trains students not for practitioners, but for scholars. Such a disorientation in vocational programs has not been tackled very seriously among its members. ``Educational internship program for student-teachers``, which is set for enhancing student`s job-related capabilities through a short-term stay at school, functions not just for educational purpose but for many other purposes of schooling political, economical, social etc.-as well. That means the program is multi-functional, mainly serving for adaptation to all kinds of school life, which as a whole would not be grasped identical with an educational program. Henceforth, we should redefine it as a "school internship program" just fit for its real characteristics. The program as a training course for teachers also functions in an educational way. However, if we are to call it an ``educational`` program, we should put our efforts to construct a theoretical framework that assumes education as a substantial reality with its unique character and autonomous principles, that proves it irreplaceable and inexplainable with any other modes of realm consisting human life.
