The purpose of this study is to understand problems which take place by doing the teaching practice of NC machine tool in the mechanical departments of technical high schools, and to show the efficient method to solve them using some questionnaires after the theoretical analysis and examination based on the relative documents, statical data, and preceding study documents.
The method of this study is to analyze the results of the frequency and percentage of 190 teachers' reply to each question of 41 questionnaires, who are from the mechanical departments of 25 technical high schools in Kyungbuk Province and Taegu City.
The synthesizing of the results of this study leads to the following conclusion.
1. Teachers' level for the NC machine tool practice is low, even if they have the confidence in the traditional mechanical course, and they feel poor at the ability to teach the NC machine tool practice to the students. So, a professional training course is needed for the teachers of the mechanical departments.
2. The NC machine tool practice is being utilized in the special practice related to the qualification certificate of the second and third grade students, and most schools have insufficient experimental equipment and professional teachers. So they have difficulty in teaching all the students, and in fact, need to have at least one NC machine tool per 10 students.
3. In the case of the curricula of NC machine tool practice, the current textbook and practice is insufficient to do education and to fulfill the aim of the curricula. So, it is necessary that for the time being we should activate the education done in the jointed laboratory and that from the 7th curriculum each school should choose the subject of Machine Tool II.
4. As teachers want to take the special and industrial training course, the teachers' training course for the NC machine tool should consist of the 50 - 70 hour course and focus on the machine operation.
5. The aim of NC machine tool education is to learn the NC programing and the skill in operating the NC machine tools.
6. The NC machine tool practice is directed to train technical experts for the industrial fields, to build up the skill in using the CAD/CAM at the manufacturing field and to learn the skill in the NC machine tool and the factory automation.
7. For the efficient education plan of the NC machine tool practice, it is needed to insurance the necessary experimental equipment for the practice management, to train professional teachers through the training course, and to do the teaching by using the general and NC machine tools simultaneously.
