The purpose of this study is to explore secondary students' progression in group norms and argumentation competency through collaborative reflection about small group argumentation. The progression is identified as the development of group norms and an epistemic understanding of argumentation with the enhancement of group argumentation competency during collaborative reflection and argumentation lessons. Participants were four first grade middle school students who have different academic achievements and learning approaches. They participated in ten argumentation lessons related to photosynthesis and in seven collaborative reflections. As a result, the students' group norms related to participation were developed, and the students' epistemic understanding of argumentation was enhanced. Furthermore, the students' group argumentation competencies, identified as argumentation product and argumentation process, were advanced. As the collaborative reflection and argumentation lessons progressed, statements related to rebuttal increased and different students suggested a range of evidence with which to justify their claims or to rebut others' arguments. These findings will give a better idea of how to present an apt application of argumentation to science teachers and science education researchers.

The scientist-led Research and Education (R&E) program aims to strengthen gifted science students' research capabilities under the guidance of scientists. Students' actual research experiences in scientist-led R&E activities range from understanding how scientists conduct research to actively participating in research. To develop R&E that promotes student agency, i.e., student participation, this study aimed to identify the pedagogical characteristics that supported gifted science students' agentic participation in the scientist-led R&E program. We conducted interviews with learners and scientists in three teams undertaking R&E activities every three months. The interview covered their perceptions of R&E activities, student participation, and scientists' support for the activities. The recordings and transcripts of the interviews were used as primary data sources for the analysis. The trajectory of each team's activities, as well as the learners' and scientists' dynamic positioning were identified. Based on this analysis, we inductively identified the pedagogical characteristics that emerged from classes in which the scientists supported the students' learning and engagement in research. Regarding agency, three types of student participation were identified: 1) the sustained exercise of agency, 2) the initial exercise and subsequent discouragement of agency, and 3) the continuous non-exercise of agency. Two pedagogical characteristics that supported the learners' agentic participation were identified: 1) opportunities for students to take part in research management and 2) scientist-student interactions encouraging learners to present expert-level ideas. This study contributes to developing pedagogies that foster gifted science students' agentic participation in scientist-led R&E activities.

The purpose of this study was to explore changes of elementary science class in student oriented group inquiry activities using a Science Writing Heuristic (SWH) template that enhance scaffolding of inquiry. The changes focused on students' written reports and perceptions of their learning environment as well as discourse patterns. One fourth-grade class of 29 students participated in this study, and a developed work sheet of science writing was utilized to scaffold student's inquiry activities. Four units in the first-semester text book for fourth grade of the-, 2007 Educational Curriculum Revision were chosen for scaffolding inquiry, and sixteen lessons of instruction were all videotaped. For investigating students' written reports, a framework based on the aspects of science inquiry by Millar (2010) was used to evaluate the coherence between student inquiry activities and their claims. Secondly, a regular fourth-grade class was selected as the control group and was compared with the experiment group using the pre- and post-test of the survey on the perception of science class and science. Lastly, students' discourse patterns of the beginning science lesson were compared with those of the closing lesson. We found that the coherence in the last class increased significantly in students' written reports compared to the first one. Findings also indicated that students' perceptions on their learning environment moved toward student-centered. Based on our discourse patterns analysis, the last class was more student-centered from being teacher-centered than the first one.

This study examined the characteristics of verbal interactions presented in TS activities with different tasks' openness levels by the cognitive levels of students through the implementation of TS program to 14 fifth graders in gifted class. Results of this study revealed that the open-type TS activities showed higher percentages of verbal interactions than the guiding-type TS activities showed and that the higher the open level of tasks was, the more high-level verbal interactions occurred. These results were showed in almost all subcomponents of verbal interactions. The results according to the students' cognitive levels showed that the higher the cognitive level of students was, higher frequency of interactions, high-level verbal interactions and a variety of verbal interactions occurred. The influence of both cognitive level of students and the task's openness on verbal interactions among students seemed to be interactive, however. In guiding-type activities, the percentage of high-level verbal interactions was not high although the cognitive level of students was high. And students in low level of cognition showed far lower frequency of interactions and their percentage of high-level verbal interactions was low even though the openness of the tasks was high. The results of this study meant that although open-type activities drew higher level verbal interactions by stimulating students' thought, the effects would be limited owing to their low cognitive level. Based on these findings, an implication was suggested that it is important to design instructional strategies and adjust openness level of TS activities to students' cognitive level so as to stimulate the thinking of students in lower cognitive level and to highten their engagement in activities.

The purpose of this study is to examine personal characteristics of two elementary students who developed individual interest in science. 201 students of two elementary schools in Seoul participated in questionnaire survey engaged in to investigate students' interest in science, engagements and preference in science-related-activities three times a year. This case study was conducted with seven students who showed typical types of interest in science. Students wrote a photo-journal for 12 weeks. They were interviewed every other week by a researcher. We analyzed two students who developed individual interest. It turns out that RF participated in doing experiments at home, and disassembling and assembling things. Participation of activities was a process of solving curiosity. When he was unable to solve problems, he searches the internet or books. Sometimes he would ask for help from his teacher. JW engaged in activities: drawing, doing experiments at home, and going to informal education center. She communicated with others by using online-offline media. Curious questions were solved by herself. The two students have a tendency to solve problems by themselves. Also, positive science-related activities were going on at home and in school. This study not only give insights and understanding of students who developed individual interest in science but also provide implication for educators to examine personal characteristics of students.

This paper is to elucidate geographical implications of fieldwork activities of everyday-life space of students of an elementary teachers college. The students depended mainly on questionaries and interview for gathering data during fieldwork. They had difficulty in processing data to visual-spatial representation, i.e. map, tables, and diagrams. But they were favourable for appling their fieldwork experiences to teaching the elementary geography. This is viewed as an unique behavioral orientation or desirable attitudes of students of an elementary teachers college. On the basis of the self-assessment and peer-assessment of fieldwork activities, it could be ascertained that the students came to understand the geographical value and significance of fieldwork activities. The fieldwork activities made them to heighten their interest of everyday-life space, and so to internalize positive their senses of place, to enforce their identities of place. According to the results of this research, we need to develop a systemic contents for fieldwork activities in geography curriculum of elementary teachers colleges.

Universities in Korea are presenting various extracurricular activities for survival and growth. Although the goals of extracurricular activities are diverse, one of the most important is to improve the academic achievement of college students. In this study, we looked at the relationship between the cumulative score of extracurricular activities by difficulty level and academic achievement. As a result, first, even if students' basic academic skills were controlled, extracurricular activities had a positive effect on student achievement. This suggests that universities should provide extracurricular activities that are more diverse and tailored to the needs of students. Second, the participation rate of female students in extracurricular activities is similar to that of male students, but the performance is very high. Third, Senior students show high levels of participation and performance. This means that it is necessary to actively increase the participation rate of female students and lower grade students. To this end, not only publicity and compensation, but also active interest and participation of instructors will be required.

Scientifically gifted students' argumentation characteristics in science instruction using the internet messenger was investigated. Participants in this study were five 9th grader in middle school in Seoul. They attended a program offered by the Science-Gifted Education Center, Seoul National University. Internet messenger (instant messenger) was used for instruction, and data were collected by saved messages. Toulmin's argument model was used as a tool for analyzing students' argumentation, and the argumentation patterns were categorized by sequence of argument operations. The results showed that in case of learner-centered instructions, there were lots of relatively higher-level argumentations appeared. On the contrary, teacher-centered instruction ended up with few or lower-level argumentation. Also there were four types of argumentation patterns emerged throughout the whole instructions. Findings suggest that the development of an instruction models and the selection of an appropriate topic be necessary for promoting the interaction between teacher and students as well as enhancing the students' ability of argument.
