The purpose of this study is to suggest how we can get over the difficulties of practical drill under experimentation concerning the units of making clothes in the curriculum of home economics. The import of this study was based on the results of the preceding studies the field of the making Korean colthes, from the standpoint of the teaching tools and teaching materials by the use of VTR, is one of the most insufficient. On the one hand, the teaching procedure here on the VTR, running 34 minutes or so, was make up with the process of making Korean men s slacks, and was led by the reseacher s own. The contents of the lesson are as follows : the shape of Korean colthes, the name of each part, the process of drawing, cutting and sewing, and the items of evaluation and arrangement. On the other hand, the two comparative groups were made to compare one with the other : One group was taught by help of VTR media, and the other only by the model performance and explanation of the instructor s own. All of the statistical data were analyzed in terms of SPSS/PC, and t-verification was made, to make difference between the two, after standard deviation was calculated according to the classified domains. The consequences of the test research are shown as below : 1.The difference of understanding was obviously made in considering that the group made a better score than the comparative one in understanding the process of making Korean clothes. 2.The difference of skill was highly made in considering that the group made a better score than the comparative one in the practical drill of making Korean clothes. 3.The difference of interests was evidentally made in considering that the group made a better score than the comparative one in the stage of making Korean clothes. Such means that the motivation and sttitude of the learners was made stimulated by the Audio-Visual material than by the traditional cramming methol. 4.The difference of frequency was fiarly made in considering that the experimeatal group made a better score than the comparative one in the frequency of individual teaching. 5.The difference of the efficiency of time-consumption was clearly made in considering that the experimental group made a better score than the comparative one. As the results of the research above, the medium of VTR proved to more effective to the achievement of schoolwork and the strategies of teaching. Therefore, more use of VTR media will help the instructors with the difficulties of practical drill in the shole process of making Korean colthes; Widely use of VTR media in teaching will be surely more fruitfull to the unit of making Korean colthes than teaching by expanation.
