Abstract
Knowledge about how to use school library and skills of using information media are required in inquiry learning. We call those as information skills. This kind of literacy should be basically taught in learning subject matters. The result of the study indicates that it is difficult for elementary students to master a considerable ratio of the literacy as a part of subject matters. Analysis of information skills in elementary, junior high and high school revealed that the skills include most of those literacy. The effect of team teaching of librarian who has profound knowledge about information media and class teacher, to teach those literacy was proved to be high.
