The nature of supervision is to improve the quality of school education by assisting the teaching activities of teachers and development of a learning community. The school library should be considered a classroom, and should offer library-assisted instruction and information literacy through collaboration between the teacher librarian and subject teachers. Therefore, it should be under the systematic and settled supervision of school library experts. However, analysis shows school library-related divisions have carried out administrative supports in the 16 city and provincial education offices. It is necessary to seek a new supervision system in order to develop and support the education of teacher librarians and the educational value of school libraries. This study suggests The Reading and Library Section which integrates reading in school and public libraries as an independent division in municipal and provincial offices of education.

The ability to utilize information of learner can do self-directed learning that increases creativity of learner. But in the middle and high schools, if 2009 revision curriculum has to be enforce, the education of information knowledge and literacy is expected to leave the education undone at schools. Therefore the ability of leaners must develop through teaching in all subjects, and so the ability of teachers in the class is very important. We examined the actual conditions about the ability of pre-service and in-service teachers, and analyzed the gap of the ability between in-service and pre-service teachers. The indexes of total ability of in-service and pre-service teachers are shown to be 74.4 points and 50.5 points out of 100. The ability of pre-service teachers is on the level about 68-percent as compared with the ability of in-service teachers. Therefor the education offices of cities and provinces and the teacher training institutes must establish for improvement of the ability of pre-service teachers.
