To do this, 4th-6th grade students (n=90) at elementary schools and 4th-6th grade students (n=126) at gifted science education institutes in Seoul were selected. Tests for science academic passion and positive experience about science were then administered and correlation analysis between the two variables was performed. Analysis of the results revealed all subcategories of science academic passion had significantly positive relationships with all subcategories of positive experience about science. The degree of correlation between subcategories of science academic passion and subcategories of positive experience about science differ significantly in some correlations (correlations between ‘importance’ and ‘science academic emotion’, ‘importance’ and ‘science learning motivation’, and ‘harmonious passion’ and ‘science-related self-concept’) between general students and science-gifted students. The degree of correlation between science academic passion and positive experience about science were also somewhat different according to each subcategory of the two variables. And this tendency was similar between general students and science-gifted students in the subcategories (‘importance’, ‘like’, and ‘time/energy investment’) corresponding to “intensity” of science academic passion, but there was a slight difference between general students and science-gifted students in the subcategories (‘harmonious passion’ and ‘obsessive passion’) corresponding to “type”. Educational implications of these findings are discussed.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121649742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process of program development followed ADDIE(Analysis, Design, Development, Implementation, and Evaluation) which is a systematic instructional design model. The subjects of this study were 15 lower elementary students(1st and 2nd graders), and selected based on their dynamic assessment evaluation on science and math performance. During the mentoring program, the students participated in various online science and math activities with mentors who were students in a university of education. The mentors had to participated in pre-training sessions on scientific and mathematical concepts, hands-on activities, and general understanding of gifted students in science and mathematics. Since the program was designed to be a flipped learning, the participants had read stories in science- or mathematics-themed books before the online programs. Then, during the online sessions, the participants engaged in hands-on activities related to the stories that they had read in advance. The college mentors provided instructional guides to the conceptual understanding as well as hands-on activities. After the program, the online survey on students’ improvement and program satisfaction was conducted with mentors and parents of the participants, in order to verify effectiveness of the program. The participating students were able to engage in the program without difficulty, and the expected effects of the program were observed. In conclusion, it is expected that online mentoring programs for gifted students in early childhood would be developed variously and appropriately.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130478479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, the scientist drama camp program developed by the P University Gifted Center was applied to secondary science gifted students. The researcher collected the preliminary report and result report written by the gifted students who participated in the program, and the video of the scientist drama camp, derived the characteristics through case analysis, and interpreted the meaning. The results of the study were as follows. First, as a result of analyzing the scientist preliminary report written by gifted students, it was found that students discovered various giftedness factors such as originality, challenge and passion, task obsession, intelligence, interest and concern, perseverance, empathy and consideration, and communication and cooperation. In view of these results, it seems that the activity of secondary gifted students’ pre-investigation of scientists provided an opportunity to discover and recognize various gifted elements of scientists. It also revealed an increased awareness of the impact of scientists on society and the impact of society on scientists. In other words, it was found that it provided an opportunity to recognize that outstanding results achieved by scientists can have a positive or negative impact on society. Third, it was found that secondary gifted students came to recognize the importance of communication, cooperation, and accountability while performing the science drama. Looking at the results of this study, it seems that the drama camp program will provide science gifted students with an opportunity to think about the nature of science, while the classes at university affiliated gifted students focus on the cultivation of knowledge and skills in science and mathematics. In addition, this program is expected to help gifted students improve the affective and social aspects of giftedness, such as cooperation, communication, and accountability.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133950115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this end, 101 students (60.5%) from the 167 participants at ASEAN+3 science gifted students camp in January 2021 completed the questionnaire of VOSI (Views of Scientific Inquiry; Swartz et al., 2008). The quantitative data collected from the questionnaire were coded as two levels, naive and informed. And two paired items about each view were combined and coded as naive, transitional, and informed. For the results, science gifted students in this study showed that the average ratio of the three views on the nature of scientific inquiry was 42.8% for naive level of understanding and 57.2% for informed level. Among three views with five items, the highest rate of understanding as informed was for the view, ‘Inquiry procedures can influence results.’ while the lowest rate was appeared with the view ‘There is no single scientific method.’ Science gifted students of Korea showed higher rate of informed level about the view, ‘There is no single scientific method.’ than other six Asian countries. But the rest two views were opposite as the understanding ratio of the informed level by other countries were higher than those by Korea. There were distinct differences among three science majors and between Korea and other Asian countries.

Studies on the inellipse of a triangle and previous studies that explored the properties between the incircle and the excircle of a triangle were analyzed. I wondered if the excircle of a triangle could be extended to an exellipse, and whether the properties that exist between an incircle and a excircle of a triangle also hold true between an inellipse and an exellipse of a triangle. Therefore, in this study, I defined the exellipse of a triangle and explored the properties. Through this study, the following research results were obtained. First, the exellipse of the triangle was defined, and its existence and uniqueness were proved. Second, we found the division ratio at which the exellipse internally and externally divides the line segment and extension line of a triangle. Third, it was revealed that various properties including the Lurier theorem for ellipses were established in triangles. Fourth, a method of constructing an exellipse of a triangle was discovered. Based on this study, it is expected that follow-up studies on the exellipse of the triangle and the expansion of the various triangle centers will be actively conducted through this study.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125703544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We questioned whether it would be possible to accurately divide paper into thirds, and studied how to fold lines into equal parts. By expanding this, I was curious about whether it was possible to fold an angle into equal parts, and it was found that it was possible to divide an angle into thirds that could not be constructed by Hilton Pederson approximation. From the relational expression for the size of an exterior angle of a regular polygon, it was inferred that folding an angle into n equal parts is related to the regular n-gon folding problem. Pierpont said that the smallest regular n-gon that cannot be origami is a regular 11 polygon, and he deduced that an 11 polygon could be folded with an approximate folding method that is easier to access than multi-folds. Therefore, the purpose of the study was set as follows. First, by using the Fujimoto approximation method and the Hilton Pederson approximation method, we investigate how to fold an regular 11 polygon approximately, and examine the relationship between the two methods. Second, we look at how to actually implement regular 11 polygon approximation using two methods using GeoGebra. The researcher observed the R&E students through the assignment research guidance and found the following implications. First, it has significance in repeatedly repeating the interaction of asking, answering, arranging, and verifying questions between teachers and students. Second, Students had the experience of solving and generalizing the problem of dividing angles into thirds with a new method called origami. Third, through the experience of actually dividing an angle into 11 parts with origami and GeoGebra, it aroused curiosity in creating coding that reduces errors and solves problems more easily. Fourth, mathematical reasoning ability and problem-solving ability could be improved by experiencing the process of proving and inferring two approximate folds mathematically.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129818804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two characteristics were identified in the collaborative problem-solving process. First, math gifted students were able to understand different perspectives while sharing different solutions and verify their own solutions and the other’s solutions based on them. Second, students were able to reinterpret others’ perspectives and apply them to their own solutions, and in this process, they were able to complete quality solutions that were different from their own solutions as well as the other’s.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125126476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After college graduation, about 60 percent of science high school graduates entered a graduate school majoring in engineering and natural science, while 45 percent of the comparison group did. This finding confirms science high school graduates are more likely to become advanced engineers and scientists than graduates from general high school. Also, the proportion of science high school graduates who re-entered medical school or entered medical professional school at graduate level was higher than the comparison group. Therefore, about 13 percent of science high school graduates made a career choice in the medical or pharmaceutical field. Finally, we divided science high school graduates’ career choices after college graduation into four categories: engineering or natural science graduate school, medical/pharmaceutical school, other graduate school, and no graduate school, and compared characteristics of each groups, based on which we suggested implications.","PeriodicalId":436249,"journal":{"name":"Korean Science Education Society for the Gifted","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116222321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
