In this paper, we suggested that those elementary school students who are gifted in science should be taught basic and fundamental concepts to solve applied problems. We developed a teaching model based on a lesson regarding the path that light takes when passing through a lens on the base of refraction of light. We applied the teaching model to scientifically-gifted elementary school students and analyzed the results. The teaching model is based on the circulation loaming model appropriate for learning such concepts. The problems were designed and applied in order to determine the students' level of concept skills held and also to develop new teaching tools to help their understanding of concepts. As a result, we confirmed that the students, who were unable to describe the path of the light before the course of instruction was given, were able to draw and explain the path of light passing trough lens by using the law of refraction following the instruction.

The purpose of this study is to analyze elementary school students' interest in virtual reality(VR) technology, usability, and the possibility of learning media. In particular, it is intended to be used for content creation for artificial intelligence(AI) education in the future. The effectiveness of elementary education using virtual reality technology was confirmed through the analysis of overseas research, and the applicability to elementary school students in Korea was analyzed. To proceed with the analysis, various virtual reality contents were provided to 5th grader of elementary school, and then, interest, usability, usefulness, and possibility of use in class and learning were surveyed. As a result of the study, it was confirmed that students' interest in virtual reality contents was very high, and that it could be used sufficiently as a learning medium. It suggests that it can be used in artificial intelligence education and data science education, which have recently been emphasized in importance. In particular, virtual reality can be used to simulate abstract data and artificial intelligence.

The purpose of this study was to analyze recognition characteristics of science gifted students on the earth system based on their thinking style. The subjects were 24 science gifted students at the Science Institute for Gifted Students of a university located in metropolitan city in Korea. The students' thinking styles were firstly examined on the basis of the Sternberg's theory of mental self-government. And then, the students were divided into two groups: Type I group(legislative, judicial, global, liberal) and Type II group(executive, local, conservative) based on Sternberg's theory. Data was collected from three different type of questionnaires(A, B, C types), interview, word association method, drawing analyses, concept map, hidden dimension inventory, and in-depth interviews. The findings of analysis indicated that their thinking styles were characterized by 'Legislative', 'Executive', 'Anarchic', 'Global', 'External', 'Liberal' styles. Their preference were conducting new projects and using creative problem solving processes. The results of students' recognition characteristics on earth system were as follows: First, though the two groups' quantitative value on 'System Understanding' was very similar, there were considerable distinctions in details. Second, 'Understanding the Relationship in the System' was closely connected to thinking styles. Type I group was more advantageous with multiple, dynamic, and recursive approach. Third, in the relation to 'System Generalization' both of the groups had similar simple interpretational ability of the system, but Type I group was better on generalization when 'hidden dimension inventory' factor was added. On the system prediction factor, however, students' ability was weak regardless of the type. Consequently, more specific development strategies on various objects are needed for the development and application of the system learning program. Furthermore, it is expected that this study could be practically and effectively used on various fields related to system recognition.

The purpose of this study was to investigate the effects of project activities on the development of problem solving skills and creativity of elementary school children. To achieve this purpose, 83 second grade children were sampled in Seoul-City, and they were assigned to experimental group and control group. Two project activities of social studies subject were treated to the experimental group for 4 weeks. And, the ‘Problem Solving Skills Test’ and ‘Creativity Test’were administered to both group children for the pretest and posttest. The collected data were analyzed by t-test to test the research hypothesis. The major findings of this study were as follows: Firstly, there were statistically significant differences between experimental group and control group on the posttest scores of problem solving skills. It showed that the posttest scores of comprehension skills[t(81)＝3.09, p＜.01], practical skills[t(81)＝2.40, p＜.05], and the total score of problem solving skills[t(81)＝4.24, p＜.01] were significantly higher than that of control group. Secondly, there were statistically significant differences between experimental group and control group on the posttest scores of creativity. It showed that the posttest scores of fluency[t(81)＝4.33, p＜.01], originality[t(81)＝2.85, p＜.01], and the total score of creativity[t(81)＝6.43, p＜.01] were significantly higher than that of control group.

This study was to examine whether musically talented adolescents' passion and achievement goals influence their deliberate practice. Of the musically talented adolescents surveyed from two arts high schools in Seoul, Korea, 597 completed and returned the questionnaires. Their average age was 17.4 years. Paired t-test on musically talented adolescents' passion(i.e., harmonious passion, and obsessive passion) and achievement goals(i.e., mastery goals, performance-approach goals, and performance-avoidance goals) indicated that harmonious passion were higher than obsessive passion. Mastery goals were higher than performance-approach goals. And performance-approach goals were higher than performance-avoidance goals. Independent t-tests were measured between high and low deliberate practice(DP) groups. High DP group showed higher harmonious and obsessive passion, and mastery and performance goals than low DP group. It was also found that two types of passion(i.e., harmonious and obsessive) positively influenced on deliberate practice via mastery goals.

The purpose of this study is to investigate the change of gaze and the change of the proof learning achievement after learning the analytic method for proof to mathematical gifted students using eye tracking technique. In order to complete the purpose of this study, a mixed method research was used, that is a combination of quantitative and qualitative research methods. Quantitative analysis was conducted based on the data obtained through the eye tracker, and qualitative analysis was also done using post interview data to make up for the quantitative analysis. The subjects of this study were 8 mathematical gifted 3rd grade middle school students in the gifted education center. The conclusions of this study are as follows. First, the learning of analysis leads to a change of gaze in the proof learning of students. The students, after learning the analysis, moved their gaze from the bottom to the top when solving the proof problem, and the occupancy rate of the gaze to the bottom of the proof was higher than the higher part. Second, the change of gaze caused by the learning of the analysis have a correlation with the achievement of the proof learning and it can be seen that the method learning improves the achievement of the proof learning of the students.

In the wake of the 4th Industrial Revolution, the problem of career education in schools has become a big issue. While various studies are being conducted on services or technologies to effectively handle artificial intelligence and big data, in the field of education, data on students is simply processed. Therefore, in this paper, we are going to design and present career prediction programs for students using artificial intelligence and big data. Using observational data from students at the institute, the decision tree is constructed with the C4.5 algorithm known to be most intelligent and effective in the decision tree and is used to predict students' path of hope. As a result, the coefficient of kappa exceeded 0.7 and showed a fairly low average error of 0.1 degrees. As shown in this study, a number of studies and data will be deployed to help guide students in their consultation and to provide them with classroom attitudes and directions.
