This thesis has verified the process of establishing Korean Education Community in the period of American Military Administration. And I also discuss the historical meaning of it. Unlike other social field, the conflict of ideology was relatively trivial in Korean Education Community of those days. That is because 조선어학회 propelled the collaboration of the two ideology as a official line. However, things were changed. Several members of the meeting had tried to practice radical language policy. That brought about troubles in Korean Education Community. Finally, the collaboration line came to collapse. The memorial day of publishing ‘조선말큰사전’ clearly showed that. While the political outlook was just like that, the fact that leftist writers' was on the list of the textbook has not been issued. On the contrary, that situation was positively selected as a way of establishing the foundation of Korean Education. These facts are historically meaningful in that those could imply the typical line of the past Korean Education. Korean Education Community of those days concluded that the conflict of ideology would not advantageous to Korean Education. Considering all this, we could not regard the Korean Education of independent government as an ideal state. That is because the post-war Korean Education was mistaken everything for political ideology, lacking in independent educational perspective. That kind of thinking has also inscribed into the viewpoint of the period of American Military Administration. This is so natural to us, so we have misconception about the historical judgement: the conflict of ideology was widespread in those days! So, if we are to appreciate the structure and the meaning of Korean Education Community in the period of American Military Administration, we should be careful not to commit this kind of error again.
