Although Internet provides a lot of convenience such as easy accessibility, interactivity, concurrency, openness, subsequent dysfunction causes serious problems. Especially elementary school students are indiscriminately exposed to the problems, and thus information communication ethics education is needed for the students. This study conducted a survey with randomly selected 5th and 6th graders in Chungbuk area, and analyzed 'students' experience and perception related to information dysfunction' and 'their experience and perception related to information & communication ethics education at school'. In addition, for the detailed understanding of students' current status and accompanying instructional approach, an additional analysis was conducted to examine the existence of the difference according to students' gender and grade. As a result, significant differences were found according to students' gender and grade in their experience and perception related to the information dysfunction and information & communication ethics education. Considering such differences according to students' gender and grade, appropriate instructional approach needs to be prepared to satisfy students' needs for more effective information & communication ethics education.

The purpose of this study was to examine the longitudinal relationships between Korean adolescents'mobile phone dependency, trajectories of depression, and self-regulated learning abilities. To achieve these goals, structural equation modeling analysis was conducted, using the 3rd, 5th and 7th wave of the data on 4th graders taken from the Korean Children and Youth Panel Survey. The results can be summarized as follows. First, growth-curve longitudinal analysis indicates that depression in 6th through 10th grade has increased. Second, mobile phone dependency among adolescents at 6th grade has a significant effect on both the initial value and the rate of change in depression. Also, the initial value and the rate of change in depression have significant relationships with mobile phone dependency at 10th grade. Moreover, both increased levels of mobile phone dependency and the rate of change in depression significantly influence adolescents'self-regulated learning abilities at 10th grade. Based on a longitudinal data set, these findings demonstrate the causal relationships between Korean adolescents'trajectories of depression and their mobile phone dependency. The findings also provide a comprehensive framework with implications for adolescents'development through an understanding of the relationships between adolescents'depression and mobile phone dependency, which impact their self-regulated learning abilities.

Objectives : The purpose of this study was to provide some basic data for effective prevention and oral health education for oral health. For that purpose, a self-administered questionnaire was distributed to the boys of three high schools in Gyeonggi Province. Methods : The questionnaire consisted of items about the practice of oral health control and knowledge of decay according to grade, number of snacking, preferred taste, and toothbrushing. Total 487 questionnaires were put to analysis using the SPSS WIN 13.0 program. Results : 1. The biggest number of the boys brushed their teeth twice a day. The 10th graders brushed teeth three times a day, and the 11th and 12th graders tended to brush teeth twice a day(${\chi}^2$=18.21, p<.05). 2. As for the way of toothbrushing, 39.0% of the boys said they brushed teeth the way they felt like, being followed by those who said they brushed teeth turning the toothbrush up and down and brushing both the teeth and gums(32.6%). As for the number of snacking, those who had snacks three times a day or more brushed teeth turning the toothbrush up and down and brushing both the teeth and gums. Those who hardly had snacks more tended to brush teeth the way they felt like than those who had snacks(${\chi}^2$=21.28, p<.05). And as for preferred tastes, those who preferred a sweet and salty taste more tended to brush teeth the way they felt like than others. And those who preferred a hot taste brushed teeth turning the toothbrush up and down and brushing both the teeth and gums(${\chi}^2$=26.85, p<.01). 3. The respondents' percentage of correct answers for 'Decay is caused by bacteria' was 81.5%. Those who preferred a hot taste recorded the highest percentage of correct answers(${\chi}^2$=21.95, p<.00). 4. Their percentage of correct answers for 'Decay is accompanied by pain from the beginning' was 78.2%. The 12th graders had the highest rate of correct answers, and the 11th graders had the highest rate of wrong answers(${\chi}^2$=11.56, p<.00). 5. Their percentage of correct answers for 'Fluorine is helpful to the prevention of decay' was 75.4%. Those who hardly had snacks recorded the highest rate of correct answers(${\chi}^2$=10.05, p<.02). 6. Their percentage of correct answers for 'There is a way to supply fluorine into the waterworks' was 29.2%, which means the percentage of wrong answers was much higher. The percentage of wrong answers was the highest in the 11th grade(${\chi}^2$=7.06, p<.03). 7. The respondents' mean scores of knowledge of decay were 13.15 of total 18. While the 12th graders showed the highest level of knowledge of decay, the 11th graders were lower in the level of knowledge of decay than the other graders. And there were significant differences(F=5.41, p<.01) according to grade with no such differences according to the number of snacking and preferred taste. Conclusions : Oral health education should be applied to the boys all through their life to have a great effect, and it is important that they should always put the oral health education into practice to be a successful education.

With the rapid increase of Internet users, Internet addiction has become a significant social issue. As Internet surfers become much younger than before, Internet addiction influences even elementary school students. While studies about adolescents' addiction are available, studies on the Internet addiction of elementary school students are very limited. The purpose of this study is to grasp the realities of 5th and 6th graders' Internet addiction, and to analyze the factors affecting Internet addiction. The result of this study shows that 22.9 percent of the sample students are in the stage of early addiction. In addition, the degree of Internet addiction is significantly different by some factors such as gender, grade, surfing time and purpose, satisfaction with parental relationship, conversation frequency among family members, relationship with friends, and satisfaction with school life. In addition, the results of the multiple regression indicate that surfing time, satisfaction with parental relationship, and conversation frequency among family members are important factors, which affect students' Internet addiction.

The purpose of this study was to identify the stressors and coping behaviors among the 5th 6th graders at Gwangju city. The subjects were 352 elementary school students and the data were collected by self-reported questionnaire from June 19 to July 21, 2003. Study instrument to investigate stressors was developed 40-items summated scale (${\alpha}$ = .87) with four subcategories: 8-items individualistic (${\alpha}$ = .72), ll-items family life-related (${\alpha}$= .70), 14-items school life-related (${\alpha}$= .76) and 7 socio-environmental (${\alpha}$= .63) factors. And the instrument to examine stress coping behaviors was also developed 30-items summated scale (${\alpha}$= .82) with three subcategories: 10-items active (${\alpha}$= .72), 10-passive (${\alpha}$= .75), and 10-mystic (${\alpha}$ = .70) coping behaviors. The data were analyzed by descriptive statistics, t-test and ANOVA using SPSS/PC+ program. The results were summarized as follows: Mean score of stressors was $66.6{\pm}14.45$ out of 160. There were no significant differences in total scores of stressors in terms of gender, grade, number of siblings and the school location The score of individualistic stressors, on the other hand, was tended to be significant higher in the 6th graders (t = -2.155, p = .032) and the school children in Gwangsangu district where has mixed rural and urban characteristics (F = 2.400, p = .049). Mean score of stress coping behaviors was $61.3{\pm}12.24$ out of 120. It was significantly different in terms of number of siblings (t = 2.108, p = .036) and the school location (F = 4.928, p = .001). In several subcategories, the mean scores of active coping behaviors were significantly higher in the only children group (t = -2.127, p = .034) and Donggu district where traditional downtown area (F = 2.410, p = .050). and passive (F = 4.013, p = .003) and mystic coping (F = 2.720, p= .030) were also significantly higher in the same district. In conclusion, the score of stressors of children in Gwangju city showed relatively low as that of other areas, and the children utilized active coping behaviors more frequently in various stressful situations.

It is necessary to accumulate the studies on the practical learning and teaching for the Mathematical talent education in elementary school. In this study, I set the 4th grade children mathematically gifted in elementary school to pose the various number calculating formulars, 4 4 4 4 = 0, 1, 2,$\cdots$10, by using to +, -, ${\times}$, $\div$, ( ). And I analysed their products. In 2007, I gave the same task to 5th graders and got a significant result. To expand the target of my study, I used the same investigating method for children of different graders. As a result, I conclude that math brains in 4th grade also can create various many number calculating formulas. I find that children pose to various many calaulating formulars becoming 0, 1, 8, 4 in order whereas they pose to a little calaulating formulars becoming 10, 6, 5, 9 orderly. Most errors are due to the order of calculation or confusion about parenthesis. This study contributes to test methods and text development for math brains in elementary school.

In this study, the STEAM elements and convergence types which appeared in the creative and convergent activities in authorized elementary school science textbooks for 5^th and 6^th graders were analyzed. For this study, creative and convergence activities presented in 9 different science textbooks for 5^th and 6^th graders were selected and the STEAM elements and convergence types were analyzed by each publisher, grade-semester, and science field. The results of this study are as follows. First, there was a large variation by publisher in the total frequency of STEAM elements and the frequency of each element in creative and convergence activities. Second, the ratio of convergence type consisting of two elements was very high, and the higher the number of fused elements, the lower the ratio appeared in overall. Third, the art (A) element had the highest frequency in all grade-semesters, and the technology (T), engineering (E), mathematics (M) elements differed in the distribution of frequency by grade-semesters. Fourth, the engineering (E) element in the 'integration' field, and the art (A) element in the fields of 'movement and energy', 'material', 'earth and universe', and 'life' had the highest frequency.

The 7th curriculum sets a basic direction based on learner centered teaching. To this end, the curriculum puts a focus on activity centered classes using teaching tools. In reality, however, elementary school teachers find using the teaching tools in their classes difficult, although there are various studies going on to improve the practical use of the teaching tools in the classroom. In this paper, we present an effective approach to utilize those prior studies on using the teaching tools in classes for 4th, 5th and 6th graders.
