In this article we drew out five definition-methods in school geometry. They are called synonymous method, denotative method, analytic method. And we analyzed them theoretically. On our analysis we tried to identify the level of common sense and the level of science in definition of those two levels on the definition-methods of circle. While the definition-method in elementary school could be regarded as the level of common sense, that in middle school could be considered as the level of science. Finally, we made the following didactical comments. Definitions in school mathematics might have the levels as regard to their roles. Thus, Mathematics teachers, curriculum developers, and text authors all need to recognize the subtle differences in the level of definition-methods.

The seventh curriculum put into operation gradually from first-year student in 2000 academic years of elementary school is subject to form and apply a step-wise level curriculum. Mathematics(correspond to junior high school course from 7th school year to 9th school year) should apply a step-wise level curriculum from 7th school year in 2001 academic years. Accordingly, mathematics teachers must diagnose actual conditions of educations, distribution tables of test results, step-wise teaching-studying programs etc. They also make proper plans suitable for actual situations of each school, prepare appropriate teaching materials and aids. I investigated preceding studies planned for preparation of putting into operation of a step-wise level curriculum. It showed that most of the studies were conducted at schools of medium or large scale and studies conducted at schools of small scale was rare. There were 113 small scale middle schools out of total 297 middle schools in Kyongsangbuk-do area in 2000. In this situation, I felt necessities of modeling of a step-wise level curriculum suitable for small scale schools. In this study, I modeled a step-wise level curriculum suitable for small scale middle schools, applied this model to 44 students in M middle school. I modeled two types of curriculum. One is a step-wise level curriculum that execute special supplementation process to students who do not complete 7-가 step successfully. The other is a step-wise level curriculum which is a regular model for a step-wise level of 7-나 step. I carried out an academic achievement test and intimacy test about mathematics before and after the application of the model. In this study, I found out that this model was very effective in academic achievement of students and helpful to declined students in scholarship. In the intimacy test, It was found out that most of the students gained confidence in mathematics, felt less anxiety, formed positive self consciousness. Therefore, I think that this model will be helpful to the application of the seventh step-wise level curriculum.

There was no significant difference of perceived stress level between rural and urban areas, but there were significant difference of stress coping behavior between them. 2. Significant difference of perceived stress level and stress coping behavior among groups of grade was found. 3. There was significant difference of perceived stress level and stress coping behavior between male and female. 4. There was significant difference of stress coping behavior according to perceived stress levels In conclusion, perceived stress level and stress coping behavior in elementary school children were different according to their grade and sex. It is important to teach them proper stress coping method, depending on their grade and sex. But, we have to focus on the development and application of stress self-control program, which enables children to cope with stress for themselves. Based on: 1. Before starting the study, the subjects should be examined about whether they have ever been on stress education program before or not. 2. The educational environments and the development and implementation of teaching program for the proper stress coping method are needed. 3. This study was performed through the questionnaire for perceived stress level and stress coping behavior, but various methods like observation, person-to-person interview should be used for the further in-depth study.

Objectives : This study was conducted in order to investigate the influences of school violence on the mental health of student victims and their parents. Methods : A total of 56 (aged 7-18) student victims and their parents were selected to participate in a survey. The students had experienced school violence from June 2012 to October 2013. They completed a set of self-report questionnaires, including socio-demographic characteristics, family relationship, Impact of Event Scale-Revised, Child Depression Inventory (CDI), Beck Depression Inventory, Revised Children's Manifest Anxiety Scale, and Parental Bonding Instrument to evaluate psychiatric complications and to understand the emotional bonding between them. Results : The student's level of impact of event was significantly related to the parent's level of impact of event (p<.001). The student's high CDI score showed positive correlation with high level of impact of event (p<.001). In addition, higher level of the student's perceived emotional support and understandability of family showed association with lower level of impact of event (p<.01, p<.05). Conclusion : The results of this study suggest that the psychiatric sequelae of school violence is seriously affected by family support and parent's level of impact of event. Therefore, more active intervention is needed for both students and their parents.

This study investigates interior and exterior environments and arrangement forms of school buildings from elementary to high school which were recently built in Daegu since the 7th Educational Curriculum. In addition, this study analyses how outside noise affects inside environment of schools. This study found that the noise level criteria of school facilities(such as exterior learning sites and outer walls of school buildings) adjacent to street of one side satisfiedly corresponded to the level and criteria, 65dB(A), of school health law. However, the noise level and vibration criteria of school facilities adjacent to street of two sides did not satisfiedly corresponded to the level or criteria, 65dB(A). In case of classrooms, the inner noise of educational facilities with windows closed and also close to both the street of one side and of two sides satisfiedly corresponded to the level or criteria. 55dB(A), of school health law. In spring and tall, the windows are more open them usual for ventilation, and leaving windows open can lead to noise from outside. Thus, it is urgent to prepare for this situation.

The study is aimed at finding out the perception of national-level curriculum among elementary school teachers in G Metropolitan City. For the study, the survey results of 124 elementary school teachers in G-city were used. According to the study, the average score of elementary school teachers recognizing national-level curriculum was 3.48 points and the self-assessment of national-level curriculum perception was 3.75, indicating that the self-assessment score was higher than that of national-level curriculum perception. Also, as a result of comparing the perception differences according to the characteristics of elementary school teachers, teachers working in schools under 20 classes had higher national-level curriculum recognition than teachers working in schools over 31 classes. The group with research school experience was higher than the group without research school experience, and the group with both research and innovation school experience was significantly higher than the group without research or innovation school experience. As a result of conducting multiple regression analysis to find out the variables influencing the national-level curriculum, school size variables showed an explanatory power of 13.1%. These results suggest that awareness of the national-level curriculum can be improved when more opportunities for teachers to access curriculum development are provided.
