In this study, learning materials that can be applied for web-based distant learning model were developed based on the characteristics of elementary school science in which investigation skills and thinking ability are considered to be important. And the effect of students' activity in a reports on student's investigating and thinking ability was investigated. While designing diverse experimental procedures, the students had. an opportunity to improve their observation attitude and way of scientific thinking. Such improvement was possible, only because the present web-based distant learning model consists of requiring an interaction between the students and a report and evaluation system which can put together such effort. Still, it was acknowledged that, as being in lack of teacher's direct support and supervision, the present web-based distant learning model might be somewhat ineffective in guiding the students in accordance with their own characteristics. For example, the students had a tendency to maintain their basic idea and style even when their reports are individually examined and corrected in terms of the format of the report.

This study investigated the types of elementary science-gifted students' coping strategies and teachers' desired teaching strategies in anomalous situations. Their epistemological beliefs about science were then analyzed on the bases of the types. To do this, 5th and 6th year science-gifted students (N=72) were asked to respond to an open-ended question with some of them being interviewed deeply. The analyses of the results indicated seven types of coping strategies in anomalous situations and were identified as follows: Abandoning, asking a teacher for help, trying the experiment again with same methods, trying the experiments again with different methods, trying the experiment again after actively analyzing the causes, recognizing the experimental results, and explaining the experimental results. Seven types of teachers' desired teaching strategies emerged and were also identified as follows: Encouraging, providing successful experimental results, explaining, providing the opportunity for trying the experiment again with same methods, providing the opportunity for trying the experiments again with different methods, providing the opportunity and help for trying the experiment again after actively analyzing the causes, and providing the opportunity and help for explaining the experimental results. The fourteen types were grouped again into four categories such as 'transferring facts', 'constructing facts', 'transferring meanings', and 'constructing meanings' on the bases of the epistemological beliefs toward knowledge and the epistemological beliefs toward relation. Educational implications of these findings are discussed.

Utilizing programming languages for data visualization can enhance the efficiency and effectiveness in handling data volume, processing time, and flexibility. However, practice is required to become proficient in programming. Therefore public data-based the problem bank was developed to practice data visualization in a programming automatic assessment system. Public data were collected based on topics suggested in the curriculum and were preprocessed to make it suitable for users to visualize. The problem bank was associated with the mathematics curriculum to learn various data visualization methods. The developed problems were reviewed to expert and pilot testing, which validated the level of the questions and the potential of integrating data visualization in math education. However, feedback indicated a lack of student interest in the topics, leading us to develop additional questions using student-center data. The developed problem bank is expected to be used when students who have learned Python in primary school information gifted or middle school or higher learn data visualization.

In this study, we developed an analogical experimental design strategy emphasizing understanding and checking stages and applied it to four groups consisting of 7th grade science-gifted students. We classified the patterns of experimental design processes and analyzed the verbal interactions among the science-gifted students at the levels of turn and interaction unit. The analyses of the results reveled that three groups were relevant to reinitiated motion and the other to backward-divergent motion. In the analyses of turn and interaction unit, the frequencies of the statements related to the task were high, especially 'making suggestion' and 'elaborated symmetrical interaction'. The analyses for each stage of strategy indicated that the frequencies of 'explain', 'question', and 'cumulative interaction' at understanding stage were high. At designing stage, the frequencies of 'making suggestion', 'cumulative interaction', and 'disputative interaction' were found to be high. At checking stage, 'making suggestion', 'receiving opinion', and 'disputative interaction' were high. In the comparison of the patterns, the qualitative differences among interaction unit were found at all the stages, whereas there were differences only between designing and checking stages in the turn cases. Educational implications of these findings are discussed.

This study examined the reasoning of gifted elementary science students in a socioscientific issues (SSI) classroom discussion on COVID-19-related trash disposal challenges. This study aimed to understand the characteristics of evidence use and decision-making difficulties in each type of SSI-related reasoning. To this end, the transcripts of 17 gifted students of elementary science discussing SSIs in a classroom were analyzed within the framework of informal reasoning. The analysis framework was categorized into three types according to the primary influence involved in reasoning: rational, emotional, and intuitive. The analysis showed that students exhibited four categories of evidence use in SSI reasoning. First, in the rational reasoning category, students deemed and recorded scientific knowledge, numbers, and statistics as objective evidence. However, students who experienced difficulty in investigating such scientific data were less likely to have factored them in subsequent decisions. Second, in the emotional reasoning category, students' solutions varied considerably depending on the perspective they empathized with and reasoned from. Differences in their views led to conflicting perspectives on SSIs and consequent disagreement. Third, in the intuitive reasoning category, students disagreed with the opinions of their peers but did not explain their positions precisely. Intuitive reasoning also created challenges as students avoided problem-solving in the discussion and did not critically examine their opinions. Fourth, a mixed category of reasoning emerged: intuition combined with rationality or emotion. When combined with emotion, intuitive reasoning was characterized by deep empathy arising from personal experience, and when combined with rationality, the result was only an impulsive reaction. These findings indicate that research on student understanding and faculty knowledge of SSIs discussed in classrooms should consider the difficulties in informal reasoning and decision-making.

In this study, we investigated the effects of analogy-generating in small group in elementary science-gifted education upon the types and the mapping errors of student-generated analogies, and the perceptions of the instruction. Fifth graders (N=37) at two science-gifted classes in two elementary schools were selected and assigned to individualistic analogygenerating (IA, n=19) and pair analogy-generating (PA, n=18) groups. After the students of each group performed the experiment and were taught about 'saturated solution' concept in the first class, they administered the test on the self-generating analogies on the concept in the second class. The students in the PA group also administered the test on perceptions of analogy-generating in small group and some of them were interviewed deeply. The results revealed that the students in the PA group made more verbal/pictorial, structural/functional, enriched, and higher systematic analogies than those in the IA group. However, there were little difference between the two groups in the subcategories of artificiality (artificial and everyday) and abstraction (abstract and concrete). The students in the PA group fewer mapping errors than those in the IA group. Many students in PA group perceived the analogy-generating in small group positively upon various cognitive and motivational aspects. However, they also pointed a few disadvantages of the activity. Educational implications of these findings are discussed.

The purpose of this study is to analyze the teaching and learning process of physical computing using coding block for elementary gifted students in science. In order to obtain implications for teaching physical computing, we set the learning objectives from the Computer and Information Literacy Evaluation Standards developed by the International Association for the Evaluation of Educational Achievement(IEA) and developed a teaching and learning program for physical computing through collaboration between science education and computer education experts according to learning objectives. The developed program was related to the use of the coding block MODI(TM) and 32 classes of physical computing instruction were conducted for 15 students of the 4th to 6th grade who belong to an education institute for the gifted in science affiliated to the University. In the physical computing class, the teaching and learning process was analyzed by collecting data such as classroom videos, class observation logs, teacher and student questionnaires, and interviews. Based on the results of the study, the implications of the teaching and learning process of physical computing using the coded blocks in the school education field were suggested. And we also explored the strategy of expanding the computational thinking through the activities of coding instruction to realize creative ideas.

The purpose of this study was to develop the method of distinction for sports gifted children, which evaluated as well as cognitive capability and physical fitness. For the validation verification of developed method, we measured physique, physical fitness and developed cognitive agility method for 369 children from 2nd grade to 6th grade. Results were followed as below: The frequency of success of sports gifted group was higher than normal group(p<.05). Total time for cognitive agility of gifted child's group in both sex were shorter than normal group(p<.05). There were no significant correlation between physique and cognitive agility time. 50m run and side step test had correlation with cognitive agility time in boys and girls(p<.05). In spatial skills, only higher tendency in sports gifted group showed. Cognitive agility had positive correlation with space perception in both boys and girls of upper grades. With theses results, we concluded that developed cognitive agility test might be synthetic evaluated method for cognitive agility as qualitative capacity for boys and girls in elementary school.

This study investigated a relationship among facilitating discourse, students' perceived challenge, and learning outcomes(persistent intention and learning achievement) in an online science gifted education program. Two hundreds and forty-two middle school students participated in the study. A survey questionnaire which was consisted of 6 items of facilitating discourse from teaching presence questionnaire(Shea, Swan, & Pickett, 2005) and 5 items of challenge from Student Perceptions of Classroom Quality(Gentry & Owen, 2004) was administered. First, the findings of this study showed that students' perceived facilitating discourse as a part of teaching presence was positively related to students' perceived challenge in an online course. Second, students' perceived facilitating discourse were positively related to persistent intention, but were negatively related to students' achievement. Third, students' perceived challenge was positively related to persistent intention and achievement. Finally, challenge mediated the relationship between students' perceived facilitating discourse and persistent intention, and the relationship between students' perceived facilitating discourse and students' achievement as well. This results suggested that online program should be designed to increase the levels of facilitating discourse.
