Students' perceived values of career play a core role in formation of their career motivation. In particular, science gifted students should build sound values of career in science and technology so that our society can retain the human resources for future science and technology. This study compared and analyzed the structure of science gifted and general middle school students' preferred job and values of career using semantic network analysis. Methodologically, we first collected science gifted and general middle school students' preferred careers and the reasons of the career choice using survey method. Then, we structuralize semantic networks of students' perceived values of their preferred careers using semantic network analysis. We identified the characters of networks that two different student groups showed based on the structure matrix indices of semantic network analysis. Findings revealed that science gifted students considered the creativeness as the most important value of career. Second, science gifted students considered more diverse values of career than general students. Third, science gifted students considered the self-realization such as displaying capability as a core value of career in STEM and medical science whereas general students considered the community service as a core value of the careers. This study identified the significant differences between science gifted and general middle school students' values of careers. The structures of students perceived values of careers can be used for teachers to counsel their students about students' future careers.

This study investigated the perceptions of the relationship among the three acid-base models of chemistry teachers. In addition, we examined how the perception of the relationship between models affected on the interpretation of concepts in each model. To investigate teachers' perceptions and interpretations, a questionnaire and interviews were conducted for 24 chemistry teachers. As results, most of the chemistry teachers recognized the three models as cumulative extension relationships. The perceptions were related to the contents of textbooks. The perception of the relationship of these models influenced on interpretations of the models' acid-base concept. In this study, we suggested that science teachers need to be aware of diverse models' roles.

This study proposed the concept model of ICT-based Creative Talented Persons as the type of persons that gifted education in the ICT area should cultivate for the 21st century. The model of ICT-based Creative Talented Persons is made of three dimensions by 3 core competencies, 9 traits, and 27 characteristics. The field experts, that is, teachers on elementary and secondary school levels evaluate the validity of the model. Teachers expressed positive opinions about the validity of the multi-dimension model of ICT-based Creative Talented Persons. We expect that this model can provide a useful guide to designing and operating ICT education and ICT gifted education for cultivating talented persons to contribute for the future society.

This study was aimed to understand the structures of preservice secondary school teachers' alternative conceptions on radioactive isotopes in the interior of earth. The structure of their conceptions were analyzed by the suggestions of Niaz (1988) based on the Lakatosian frameworks. The survey was carried out on a group of seventeen students who were major in science education. The research method was open-ended written questionnaire. The results of this study show that students had apparent alternative conceptions. The high temperature and pressure' explanation for radioactive decay in earth's interior had most import effects on their alternative conceptions. It was also intended to survey their conceptional change by our teaching strategies of the philosophy of science in order to construct science concepts.

'I'his study investigated students' attitude toward mathematics. and how behavior/cognitive training affects level of math anxietv and level of math achievement. Subjects were all the freshmen attending Taejon Science High School, and they were given Mathematics Attitudes Scale and Attributional Style Questionnaire prior to and post training sessions. Twenty out of 84 freshmen voluntarily participated in nine sessions of training program. Participants were asked to do self-evaluation. Math achievement was measured prior to and post training. and was compared between two groups. Training program utilized behavior/cognitive approach. such as understanding one's feeling through muscle relaxation, breathing and meditation; modifying negative attributional style; imitating effective cognitive strategies for math problem solving, and so on. 'I'he result shows that students' math confidence in general was relatively low out of expectation, a nd they perceived teachers not supporting their math abilities :IS much as expected. On the other hand, students in general had strong math achievelment needs, and considered math utility very high. Sex difference was seen in the attitude toward female math abilities, to result that female students had more positive perception than male students. Female students of 'I'aejon Science High School seem free from conventional idea about female abilities including theirs. Participants' ~attitude change was compared with non-participants. and participants showed statistically significant change in their math confidence, and also in their math achievement. Participants had much higher math confidence and ~achievement than non-participants. And, they showed increased level of perceiving teachers' expectation. more realistic in needs, and more involvement in math. Math achievement was found positively related to math confidence, and participants' math achievement change was explained by their belief in math utility. Not only training program effect hut also participants' voluntary involvement and teacher\ulcorner' support of the program and participation seem to increase their math achievement. Based upon the result of study it was suggested that behavior-/cognitive training program be provided along with academic curricula for gifted students of Korea to help their emotional and psychological development enhance the efficacy of their cognitive learning.

In this study, an enriched in-service program for teaching scientific creativity was developed and implemented using the scientific creativity activities developed by Park, Park, & Lee (2008). In this program, science teachers performed scientific creativity activities by themselves and practiced the development of actual teaching materials. As a result, science teachers mentioned that they could achieve their goals by learning about various actual teaching materials and teaching strategies for gifted education. They also mentioned that the in-service program was interesting, had appropriate levels of learning difficulty, and that they would apply the teaching programs and teaching strategies to actual gifted education. Observing teachers' actual learning processes during the in-service training course, it was found that they actually participated in the in-service program for a long time intensively and could improve conceptual understanding in depth, but it was necessary to long-term creative thinking practice for being beyond the level of students' creative activities. Finally, from the analysis of teaching materials developed by teachers at the final step of the in-service program, it was found which aspects were developed well or were unsatisfactory, therefore, these findings could be applied for more improved in-service programs.

This study attempted to present a better direction for the development of STEAM education in science gifted and talented education by making a comparative analysis of the trends date and discussing the implications based on that through Korea Education & Research Information Service(KERIS) The results were as follows: First, the results of the analysis in the order of the published year(2011) showed that since one paper appeared in a journal, the number of the papers has continued to increase. Second, the analysis by research objects found the highest number of the studies on elementary school gifted students; followed by on middle school gifted students; on elementary school gifted students and general school students and teachers; and high school gifted students, middle school gifted students and general school students, and elementary, middle school gifted students, respectively. However, research targeted at infants and college students did not exist. Third, the analysis by research subjects found that science gifted education consists of mainly programming/curriculum and creativity. In addition, the higher number of the researches on creativity suggests that science gifted education is closely associated with not only scientific creativity but science education's nature of increasing the interest and understanding of science and technology. Fourth, the analysis by research methods revealed that the number was the highest regarding development and research studies, followed by experimental research, survey research, qualitative research, and literature research.

The purpose of this study was to investigate the difference of teachers' interaction with their students when teaching science in New York (NY) and in Korea. As part of the 2011 Korean International Teacher Fellows (KITF), supported by the Ministry of Education, Science and Technology (MEST) and the National Institute for International Education Development (NIIED), Korean science teachers observed, for six months, New York's science classes in terms of how teachers interact with their students and how students learn science during science instruction. The participants were 10 science teachers in five middle and high schools that taught Physics, Chemistry, Biology, Earth Science, and Environment Science in NY. The National Board for Professional Teaching Standards (NBPTS, 2003) and Instruction as Interaction (Cohen et al., 2003) were used as an instrument to identify each teacher's teaching and classroom interaction. Several characteristics of science classes in NY were revealed, which are different from Korean science classes. First, science teachers in NY dominantly put more focus on their subject of teaching during science interaction while, Korean science teachers not only teach science but also do counseling to students as a homeroom teacher. Second, science teachers in NY acknowledged the students' individuality and have positive experiences of professional development supported by their school and district more than Korean science teachers do. Third, science teachers in NY sometimes showed limited knowledge about the concepts of science and lack of collaboration with other science teachers. This characteristics may prevent the school from strengthening its subject program and keeping equity across the grade levels and courses.

This study aims to compare the difference between the recognition of professionalism and teaching efficacy of the gifted education teacher by majoring in education for the gifted from the graduate school. The subjects were 44 graduate students in gifted education major and 56 gifted education teachers of elementary school who did not major in the education for the gifted. The results were as follows. First, the education for the gifted children majors showed higher statistical significance in the subject knowledge, the instructional strategies, the understanding gifted student, personal efficacy and outcome expectancy than the teacher who did not major in the education for the gifted children (p<.05). Second, in the results of Two-Way ANOVA by the major status in education for the gifted children and the gender, there was the interaction effects in the subject knowledge, the understanding gifted student, personal efficacy, and the females were influenced by the recognition of professionalism and teaching efficacy by the major status in education for the gifted children more than males. In the results of analysis on the major status in education for the gifted children and career for gifted education, the instructional strategies and personal efficacy showed the significant interaction effect (p<.05). Third, in the results of analysis on the relations between the recognition of professionalism and the teaching efficacy, all subordinate scopes of the recognition of professionalism and teaching efficacy showed the significant positive correlation (p<.05). In the results of the multiple regression analysis, the subject knowledge and the instructional strategies have effects on the personal efficacy. So the majoring in education for the gifted children from the graduate school may have significant effects on development of the subject knowledge and the professionality of the instructional strategies of the gifted education teacher, further, it can be said that has positive effect on teaching efficacy.

The purpose of this study was to investigate characteristics of mathematically gifted high school students' thinking in design activities using GrafEq. Eight mathematically gifted high school students, who already learned graphs of functions and inequalities necessary for design activities, were selected to work in pairs in our experiment. Results indicate that logical thinking and mathematical abstraction, intuitive and structural insights, flexible thinking, divergent thinking and originality, generalization and inductive reasoning emerged in the design activities. Nonetheless, fine-grained analysis of their mathematical activities also implies that teachers for gifted students need to emphasize both geometric and algebraic aspects of mathematical subjects, especially, algebraic expressions, and the tasks for the students are to be rich enough to provide a variety of ways to simplify the expressions.
