The purpose of this study is two-fold. One is to provide the teachers of Home Economics with the basic reference data ofthe relevance betwen Home Economics and other subjects taught in the middle schools for the purpose of bringing out more efficient classroom teaching. The other is to help the teachers, the textbook writers, and the curriculum reformers improve the curricula ofthe middle school on the basis of this research. The conclusions drawn from this study are as follows: 1) The units of Human development and Family Relationship should be teught with reference to Korean Language, Ethics, and Music. 2) The unit of Adolescence Development is dealt with in Physical Education and in Ethics as well, which seems to indicate that there was no interdisciplinary consideration and cooperation beefore/when the curricula were made. 3) The unit of Nutrition which appears in the first grade in Home Economics has a close second grade in Natural Science. It is thought that the interdisciplinary themes ought to be organized cooperatively among subjects for efficiency of study. 4) Since the unit of Clothing is not dealt with in the other subjects, it can be developed in Home Economics on its own. 5) As the unit of Housing is closely related to Teachnology, it should be taught on the basis of Technology. 6) The textbooks of all subjects should be written based on the interdisciplinary research and cooperation. They should be organized in order not to overlap or repeat the same topic in the same level if it is not necessary.
