In this paper, in order to offer the opportunity to indirectly experience STEAM education and the profession of a quantum computer professional, one of computer experts as a promising occupation of the future, its correlation to the national curriculum was analyzed. STEAM educational program in this paper was developed through which the third or fourth graders in elementary schools can learn about a quantum computer expert and think about it in relevance to their future careers. Yet, it's almost impossible for the students to understand the basic theories of quantum computer based on quantum mechanics, one of most difficult areas of physics. Accordingly, in this proposed textbook, gamification mechanism was applied to arouse students' interest. Moreover, the textbook was developed and applied to the field directly in the way that students would be able to indirectly experience quantum spin, one of most basic principles of quantum computer, quantum cryptography related to quantum computer, incomplete quantum computer and etc. The STEAM educational program for future careers offered in this research is expected to create positive effects for students to explore careers relevant to IT, and to develop related qualities.

In order to provide basic data for developing problematic drinking prevention program through the investigation of the knowledge and attitude on drinking of the elementary students, a survey was conducted covering 630 fourth, fifth, and sixth graders in 5 elementary schools, in Seoul. Data was collected by using structured questionnaire. The results of the survey analysis were as follows : 1. Among the students under inquiry, $55.4\%$ answered they had the experience of drinking and $1.9\%$ of them enjoy the drinking. 2. The degree of drinking-related knowledge of respondents were 8.41point with the highest score being 13. The score were significantly higher in the students with good school record and higher mothers' educational level than those of other group. 3. With respect to the attitude of students toward adults' drinking, $54.8\%$ responded that inebriated adults in the bus or subway cause inconvenience to others. Students who maintain good school grades, are satisfied with school lives, whose fathers have high educational background or who receive great attention from parents showed more negative and strict attitude toward adults' intoxicated appearance. Concerning the drinking at home, $51.6\%$ of respondents said they hope that adults do not drink at home. Students who have experience of drinking and whose parents drink revealed more generous attitude toward adults' drinking at home than those who do not. With regard to the drinking of friends or senior students, $55.0\%$ of students said they try to stop the drinking. Respondents with no experience of drinking were more generous toward the drinking of friends and colleagues than those who drank before. Students who are in low graded. maintain high school marks, face no problems in school life or receive great attention from parents demonstrated greater disapproval of drinking. Most respondents$(65.3\%)$ said they were not interested in the scene of drinking in mass media. Those having experience of drinking or parents who drink showed more tolerant attitude toward drinking in mass media than those who do not. Students who are in low grades, face many problems in school life or receive small attention from parents showed greater tendency to find the scene of drinking attractive. 4. The more knowledge they get, the more rigid view they had in drinking.

In this study, by examining the characteristics of boys and girls which would appear in the performance process of Goldberg machine activities, it would be attempted to provide the implications for the development and teaching methods of gifted and talented programs. The object of study was organized into separate 2 groups of boys and girls by each, composed of a total of 16 people among 5th graders of the gifted class in elementary school, located in Gyeonggi province. The final assignment was to make the Goldberg machine in order to have the beads get to the target spot latest, in which the analysis was implemented qualitatively by participating in and observing the performance process of students. After dividing the Goldberg machine activities into the steps of planning, production, outcome, assessment and reflection, their analysis results are as follows: First, in the planning stage, the girls explained minutely the process of Goldberg machine in writing, whereas the boys represented it visually simply. Second, in the production stage, the boys showed the task commitment by trying to realize the machine as designed initially, but the girls showed their appearance to represent it simply and easily. Third, in the sophistication and efficiency of the machine production, the boys were superior to the girls, and in the creativity and diversity of the use of materials, the girls were more excellent. Fourth, in the assessment and reflection, the boys evaluated it individually, and the girls showed their appearance to evaluate it by reflecting others'thinking. Hence, when developing and teaching the gifted and talented programs, it would be required that the teaching and learning contents be recomposed by considering the gender, or that the various class strategies be sought. Further, the broader and more systematic studies, on the performance process of gifted students based on the gender, should be carried out.

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.

In the 21C information-based society, there is an increasing demand for emphasizing communication in mathematics education. Therefore the purpose of this study was to research how properties of communication among small group members varied by mathematical problem types. 8 fourth-graders with different academic achievements in a classroom were divided into two heterogenous small groups, four children in each group, in order to carry out a descriptive and interpretive case study. 4 types of problems were developed in the concepts and the operations of fractions and decimals. Each group solved four types of problems five times, the process of which was recorded and copied by a camcorder for analysis, among with personal and group activity journals and the researcher's observations. The following results have been drawn from this study. First, students showed simple mathematical communication in conceptual or procedural problems which require the low level of cognitive demand. However, they made high participation in mathematical communication for atypical problems. Second, even participation by group members was found for all of types of problems. However, there was active communication in the form of error revision and complementation in atypical problems. Third, natural or receptive agreement types with the mathematical agreement process were mainly found for conceptual or procedural problems. But there were various types of agreement, including receptive, disputable, and refined agreement in atypical problems.

The purpose of this study was to examine vegetable & fruit (V/F) intakes, beliefs and self-efficacy regarding V/F consumption, nutrition knowledge and eating behavior of elementary students. A survey was conducted to the 4th graders (n = 234) at two elementary schools in Guri, Kyunggi-do. About one-fourth of subjects were overweight or obese. Subjects had 4.2 servings of V/F a day, consuming 340.2 g of V/F. Girls consumed significantly more amounts of vegetables than boys (p < 0.05). Girls were more favorable regarding V/F consumption (p < 0.01), and believed more strongly on advantages of having V/F such as “good for skin” constipation prevention (p < 0.001) and cancer prevention (p < 0.05). Boys felt more strongly in disadvantages or barriers of eating V/F, including mother's cooking time constraints (p < 0.01), lack of past experience of eating V/F, and family members' disliking of V/F (p < 0.05). Girls felt more confident in eating V/F (p < 0.05) than boys; they also felt more confident in specific items of "eating fruits/salads instead of cookies/chips for snack" and "eating fruit juice/vegetable juice instead of soda"(p < 0.01). Subjects showed low level of nutrition knowledge, especially in items such as balanced meals, recommended servings of V/F and vitamin deficiency. Compared to boys, girls had more desirable eating behavior such as eating adequate amount of meals (p < 0.001), having a variety of foods, eating fruits daily, and having fatty foods less frequently (p < 0.05). Intakes of Ca and K were quite below the recommended level, while the intakes of protein, Na and vitamin A intake were much above the Dietary Reference Intakes (DRI) for 9-11 old children. Nutrient intakes expressed as %DRI was higher in girls for vitamin A (p < 0.01), energy and riboflavin (p < 0.05). High V/F consumption group (${\geq}5$ servings of V/F a day) compared to the counterparts showed higher self-efficacy and had better eating behaviors. Nutrition education for children should focus on increasing consumption of V/F, by helping them to increase self-efficacy for eating V/F and to recognize the benefits and reduce the barriers of eating V/F, especially in boys. It is also needed to provide nutrition information for balanced meals or increasing V/F consumption, and help the children to adopt desirable eating behavior.

In this study, we investigated the characteristics, the mapping understanding, the mapping errors, and the perceptions of student-generated analogies on the separation of mixtures using the sizes of particles by elementary school students' approaches to learning. Fourth graders (N=92) were selected and administered with the tests on the approaches to learning, self-generating analogies, and perception of self-generating analogies. The results revealed that the meaningful learners made more analogies, especially structural/functional, enriched, and higher systematic ones than the rote learners. However, there were little difference in students' approaches to learning in the subcategories of representation (verbal, pictorial, and verbal/pictorial), artificiality (artificial and everyday), and abstraction (abstract and concrete). The meaningful learners had deeper understanding of the analogy and fewer mapping errors than the rote learners. In addition, the numbers of the shared attributes included in student-generated analogies and the scores of the mapping understanding of the meaningful learners were significantly higher than those of the rote learners. Many students, regardless of students' approaches to learning, had positive perceptions of the self-generating analogies in various cognitive and motivational aspects. However, they also point out the various difficulties in the self-generating analogies as their disadvantages. Educational implications of these findings are discussed.

This study analyzed the difficulties elementary school students have in role-playing analogy activities for concept learning of heat transfer. Eleven fifth graders were given an orientation class on role-playing analogy activity, a class for concept learning of heat transfer as presented in a textbook, and then they performed the role-playing analogy activity with concepts of heat transfer. After the classes, researchers investigated the difficulties students encountered through questionnaires and interviews. The following are results of the research: Difficulties that students faced in role-playing analogy activity can be classified into five types. First, students encountered difficulties in expressing the analogy. The students who had difficulties in expressing the analogy focused on expressions outside the science concepts or lacked understanding of the science concepts. They also had difficulties in expressing the analogy because they lacked the expressiveness of analogy or abilities in mapping errors. They had difficulties in expressing the planned role-playing analogy in a narrow space. Second, students also experienced difficulties in performing activities due to lack of understanding on activities or lack of experience. Third, students experienced difficulties in selecting roles because they preferred the specific role or unwanted the specific roles. Fourth, the members of group experienced difficulties in group activities because they did not concentrate on activities, failed to perform roles, or showed attitudes of an onlooker. Fifth, they experienced difficulties in communications due to unilateral communication, conflicts of opinions, and lack of opinions.
