The purpose of this study was to analyze the effectiveness of injury prevention education on elementary school students. We are selected two elementary school in Tejeon, one was intervention school, the other was control school. Surveys were completed before the begining of the interventions in February in 1994 and again after their completion in July 1994. Intervention group was 284 students in pre-test and 218 students in post-test. And control group was 253 students in pre-test and 208 students in post-test. The results of this study was followed. 1. In the general characteristics of subjects studied, sex, mother education, father education, economic status, number of household, and traffic environment were not significant difference between intervention and control group(p>0.05). 2. The contents of injury prevention education that subjects wished to learn, were not significant difference between intervention and control group(p>0.05). Also the mothods of that were significant difference between intervention and control group in pre-test(p<0.05) but not in post-test(p>0.05). 3. Education in knowledge, attitude and practice of injury prevention was slightly effectiveness. Change in attitude of injury prevention was higher than in knowledge and attitude of that we guess that they require a lot of education in the pedestrian prevention. 4. Reative risk between intervention and control group in injury incidence was 1.53 in hospital-care students, and 1.43 in home-care children. Also relative risk of total injury incidence was 1.38, therefore we knew that injury incidence after education was reduced. 5. In the analysis of injury causes, pedestrain injury was remarkably reduced at hospital-care students in two group. At home-care students, two groups were high proportion in play injury. 6. In the analysis of injury places, intervention group was high proportion at near-the house in pre-test(35.4%) and at school in post-test(36.4%). And control group was high at inside-the house in pre-test(31.5%) and at near-the house in post-test(28.2%).

The purpose of this study is to investigate the effect of a multiple cognitive conflict strategy at remedying student's misconceptions. Elementary students have many misconceptions about the brightness of the electric bulb in simple dual circuits. Most of the misconceptions can be summed up as 'the more batteries or the fewer bulbs, the brighter is the output.' The students have learned about the brightness of the electric bulb while connected to a battery in Grade 4 and the brightness of multiple electric bulbs in Grade 5. However, about $50%$ of the students remain with the firm misconception that the brightness of the bulb is related to the number of source batteries. This strong misconception may not lead to a conceptual change in the case of only one cognitive conflict. This study used a multiple conflict strategy while tackling the cognitive conflicts in the students as they solved the problems many times. It involved 160 grade 5 students. The result was they often changed their misconceptions and used more scientific thinking than the same grade students of other schools. It remains to be seen if this success will transfer to other schools and students and we intend on studying further the differences in students regarding this learning process.

Objectives: This study was conducted to investigate the snack intake and brushing behavior according to the oral health education experience in some schools in Busan, and to investigate whether the oral health education experience affects the snack intake and brushing behavior. Methods: This study surveyed the entire fourth grade of elementary school in two districts by participating in university-linked oral health education activities run under the jurisdiction of the education office business to examine changes in the behavior of elementary school students in their snack intake and toothbrush. The survey was conducted on oral health education in elementary schools, prior oral health education experience before and after the activity, whether or not the brushing classroom was operated, and contents related to eating snacks and brushing behaviors. Result: Among the general characteristics of some schools in Busan, 69.9% of students have experience in oral health education and 30.1% of people have no experience in oral health education. 20.0%, 16.3% were 'normal' and 63.7% were 'helpful'. The brushing behavior according to the oral health education was 44.9% in the number of brushings, 44.9% in the number of brushings, 45.7% in 2-3 minutes in the time of brushing, 41.2% in the brushing method by sweeping the brush up and down. In the daily brushing period, 'after breakfast' was the highest at 72.3%, and the parent's brushing instruction was 'to lead' at 65.1%. The amount of sugar in subjective snacks was the highest with 60.6% of sugar content, and the parents had the highest level of 52.2% for parents' snack intake. This result was more significant than the students without oral health education experience. Conclusion: Based on the results of this study, the number and time of brushing, the method and timing of brushing according to the experience of oral health education. Students who had oral health education experience higher than those who did not have oral health education, but had a lower tendency to brush after lunch at school and before going to bed. For better oral health, the effect of oral health education will be better if the school has more systematic toothbrushing at lunch time and parental guidance at home.

In National Curriculum of Science revised in 2007, 'Free Inquiry' was newly introduced to increase student's interest in science and to foster creativity by having students make their own questions and find answers by themselves. The purpose of the study was to analyze characteristics deployed in the processes of elementary school students' free inquiry activities applying a brain-based evolutionary science teaching and learning principles. For this study, 106 the fifth grade students participated, and they performed individually free inquiry activities according to a brain-based evolutionary approach. In order to characterize the diversifying, estimating-evaluating-executing, and extending-applying activities in behavioral domain, the free inquiry diary constructed by the students, observations by the researcher, and interviews with the students were analyzed both quantitatively and qualitatively. The major results of this study were as follows: First, the students preferred basic inquiry process skills and the majority of the students selected observation as a major approach of their inquiry. The reason was found to be that they were accustomed to only typical basic inquiry skills which is frequently presented at textbooks and regular instruction and didn't have appropriate experience for using relevant integrative inquiry skills. Second, most of the methods diversified and selected by the students were confined to descriptive explanation rather than causal one. Third, both of the science attitude and academic achievement were associated with the number of diversified methods and the selection of appropriate method. Based on these findings, implications for supporting domain novices in inquiry learning environments are advanced.

The purpose of this study was to examine the relationship of bully/victim experiences and bioethics of 5th and 6th graders. Participants were 326 elementary school students. Methods: The data was collected from 1th to 30th October, 2014 in G City. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation and multiple regression and Scheff$\acute{e}$ post-hoc analysis by SPSS 18.0. Results: First, in regard to bioethics, significant factors were liking for growing plants (p<.001), emotions after killing insects (p<.001) and the number of friends (p=.003). In regard to bullying experiences, significant factors were gender (p=.021), religion (p=.026), participation in religious activity (p=.019), liking for growing plants (p=.009), insect killing experience (p=.009). The bioethics score of the victim group (2.70 point) were higher than the bully group (2.49 point). The relationship between bully/victim experiences and bioethics was negative. The factors affecting bioethics were liking for growing plants (${\beta}=.159$, p=.004), the number of friends (${\beta}=.124$, p=.030), experiences of being bullied (${\beta}=.352$, p<.001), emotions after killing insects (${\beta}=-.135$, p=.011). Conclusion: Therefore, based on the results of this study, it is required to develop rich learning content and a variety of teaching and learning models for bioethics. Efficient bioethics program would help elementary school students have a higher bioethics awareness. The entire society and families should wake up to the evil effects of school bullying and make concerted efforts to root it out with a sense of responsibility.

This study analyzed the relationship between self-directedness of science-gifted elementary students and their expression of scientific creativity in science-gifted class. A science-gifted program on the topic of Hydraulic Machine was implemented to 34 fifth-graders in the Science-Gifted Education Center of an education office in Seoul, Korea for four weeks. The self-directedness of the gifted students was divided into three types of 'General, Scientific, and Topic-Related Self-Directedness'. The products of the students' activities were assessed by using a scientific creativity assessment formula. Qualitative research, such as analysis of observations and interviews, was also conducted in order to identify characteristics that were not apparently revealed by quantitative data. The main results of this study are as follows: First, science-gifted elementary students' general self-directedness and their scientific creativity were significantly correlated (r=.373). Second, the students' scientific self-directedness and scientific creativity did not have a significant correlation (r=.294). Third, there was a positive correlation between the students' topic-related self-directedness and their expression of scientific creativity. Their self-rated scores (r=.420) for the topic-related self-directedness and the number of activity types associated with the topic had a positive correlation (r=.350). Fourth, the students were categorized into four groups according to the levels of their self-directedness and scientific creativity, and the result showed that Type HH (high self-directedness and high scientific creativity) was the most common type (15 students, 38.5%), followed by Type LL (low self-directedness and low scientific creativity) (11 students, 28.2%). Eight (20.5%) and five students (12.8 %) belonged to Type LH (low self-directedness and high scientific creativity) and Type HL (high self-directedness and low scientific creativity) respectively. Fifth, the classroom observation of the students in groups revealed that groups with more number of Type HH demonstrated better cooperation and performance. Sixth, the analysis results of the observation were almost matched to the results of the self-directedness and scientific creativity tests. The students with higher self-directedness demonstrated active class participation and good cooperative skills. The students with higher scientific creativity had a tendency to generate creative ideas more frequently in given situations. Seventh, dynamic activities were perceived as enjoyable and exciting by 76.9% of the students, but static activities that require creativity were regarded as interesting only by 23.1% of the students. Among the students who were satisfied with both the creative and static activities, Type HH accounted for the largest proportion (55.6%). In conclusion, factors such as students' interests, initiatives, and attitudes displayed through voluntary participations originated from their own daily life can predict the degree of scientific creativity associated with the topic. Also, when students were categorized into four types according to the level of self-directedness and scientific creativity, there was a tendency of active behavior in class, cooperative skill, and activity satisfaction. This suggested that we should consider self-directedness and scientific creativity in selecting the gifted, grouping them in class, and designing and executing programs for science-gifted elementary students.

The purpose of this study is to investigate elementary students' communication in process of applying mathematical modeling. For this study, 22 fifth graders in an elementary school were observed by applying mathematical modeling process (presentation of problem ${\rightarrow}$ model inducement activity ${\rightarrow}$ model exploration activity ${\rightarrow}$ model application activity). And the level of their communication with their activity sheets and outputs, observation records and interviews were also analyzed. Additionally, by analyzing the activity cases of and , this study researched that what is a positive influence on students' communication skills. Whereas showed significant advance in the level of communication, who communicated actively on speaking area but not on every areas showed insensible changes. To improve communication abilities, cognitive tension and debate situation are needed. This means, mathematical education should continuously provide students with mathematical communication learning, and a class which contains mathematical communication experiences (such as mathematical modeling) will be needed.

The purpose of this study is to provide an opportunity for better understanding and application of 2009 revised elementary school mathematics textbooks through survey data and focus group interview on structures of textbooks. First, We collect online survey results which 2333 elementary school teachers participated. Next, We interview focus group(8 teachers) about shapes of textbooks, quantity of learning contents, activities and problems for evaluation in the mathematics lessons. Storytelling is especially issued in the 2009 revised mathematics curriculum. We intensively discuss learning and teaching methods with application of storytelling textbooks; interests of students, role of storytelling textbooks etc. As results of analysis, the positive rate to use the 2009 revised textbooks is relatively high about shapes and activities of textbooks. But there is more considered about storytelling method. Storytelling may be positive on improvement of learning interests and participation of students. In order to develop these advantages, studies in relation of storytelling are more proceeded and teaching materials for teachers are required effectively in order to applicate to the elementary school.

The purpose of this study was to survey the problem of teachers' narrative reporting of children's science learning in elementary school report cards. For the purposes of this study, a questionnaire, comprised of 6 questions and an analysis tool (Cronbach's $\alpha=.70$) were developed to categorize the answers. The survey was conducted by 53 teachers, who are currently taking 5th ade in elementary school, and the results are as follows: First, they interpreted the same content of report cards in a variety of different ways. Second, they exhibited a number of different principles and criteria in terms of preparing the content of narrative report cards. Third, they experienced difficulties in preparing narrative report cards on science teaming which required explanation of complete processes. Fourth, most teachers surveyed answered that the content of their narrative reports on science learning did not communicate specifically the students' achievement and further studies. Fifth, the activities related to preparing the content of the science learning on narrative reports was widely perceived to be useless for teachers' professional development. Finally, teachers made a number of alternative proposals to overcome the current, perceived problems of teachers' narrative reporting for children's science learning in report cards. Based on the results of this analysis, alternative forms and content of narrative reports on science learning were discussed.
