In order to normalized the Earth Science Education, experiments and geologic field trainings are very important. But it have not carried out on account of many difficulties in current High School of Korea. These difficulties are lack of time, many problems of the text book, heavy teaching load, shortage of facilities and experimental equipments, and poor quality of teacher etc. The practical training of geologic field trip is very important in Earth Science Education. Finally, wirter propose a new teaching plan of geologic field training as follows: 1. The teacher must prepare the guide paper of field geologic training. 2. Subjects of practical training must simplify. 3. The teacher must take a pre-field investigation in order to get the teaching plan and the preparation of practical field training. 4. Let students observe for themselves on this guide, as if they were geologists. 5. The teacher must conclude about practical training after the working.
