In this case study, we investigated the characteristics of secondary beginning science-gifted education teachers' reflection on their science teaching with coteaching through mentoring. We selected two beginning teachers with less than one year teaching careers in secondary science-gifted education. The teachers planned, performed, and reflected together on their science teaching for science-gifted students during twelve class hours over four times. Since the second class, pre-, during-, and post-mentorings were conducted. We observed their science classes with coteaching through mentoring, and analyzed their reflective journals in the views of productive reflection. The analyses of the results revealed that 'instructional strategies and instruction for science-gifted education' and 'science-gifted students' were most frequently included in their reflection regardless of class time. 'Curriculum for science-gifted education' were also frequently included although fewer than the two aspects. However, 'subject matter knowledge' and 'assessment in science-gifted education' were hardly included. Two to four aspects of the five were variously integrated in their reflection. The integrations among three to four aspects were especially more frequently included than those between two aspects. The integrations of 'instructional strategies and instruction for science-gifted education' or 'science-gifted students' with the other aspects were also found to be the most frequent. These results suggest that coteaching through mentoring can promote beginning science-gifted education teachers' productive reflection on their science teaching.

This study aims to analyze the changes of goals and contents of middle school geography education following up the changes in the Korean social studies curriculum over time. The main findings are as follows. First, From the Syllabus period to the Third Curriculum, geography education, history education, general social studies education in the middle school social studies were directed and managed independently. However from the 4th to the 7th Curriculum, the demand for the virtual integration in middle school social studies increased sharply. Since 2009 revision, social studies suffered an identity crisis as integrated subject matter because history education was separated from the social studies and interdisciplinary units were abolished. In spite of much criticism, however, an odd form of social studies integrating geography and general social studies still remains. Second, the stronger the demand for the social studies integration in middle school, students' social studies learning load had become heavier due to severe competition with other areas to ensure more portion in the integrated structure of social studies. Since geography education did not reflect the new tendency of the geography in the integrated structure of middle school social studies, the gap between the geography and geography education has increased and knowledges of geography growing became separated from students' experience. In conclusion, the integrated structure of social studies in the middle school hindered the geography education development as it limited the autonomy of geography education in terms of curriculum development.

This study is to develop a competence model for school principals that provides effective career and vocational education (CVE) at middle schools. This model can be used as an indicator for identifying the expertise levels of principals in CVE and to help them develop the necessary skills. Research methods included literature review, basic research, the Delphi technique, analytic hierarchy process (AHP), and surveying. The results were as follows. The competence model for CVE for middle school principals consisted of three competence groups, nine competence elements, and 67-item behavior indicators. First, the three competence groups included the competence to build a school system for CVE, the competence to support CVE at school, and the competence to create a school environment for CVE. Competence to support CVE at school turned out to be most important in the AHP analysis. Second, competence elements included goal management, performance management, the creation of educational culture, support for educational activities, support for school curriculum, support for students, human resources management, resource management and community management. According to the AHP analysis, support for school curriculum was the most significant among the nine competence elements. Third, the behavior indicators were identified items in three areas: 18 items for individual propensity, 18 items for knowledge, and 31 items for performance.

Career and academic Counseling is often viewed as the catalyst for frequent and consistent interaction with students, but it is more than simply advising students about which majors, universities or jobs to consider. Ongoing, personal contact of career and academic counselors with students is an essential component in long-term career-related efficacy. But statistics show that high schools in non-urban or rural areas face significant issues different from those schools in metropolitan or suburban contexts, failing to maintain the significant number of teachers enough for effective career and academic counseling. This article proposes an alternative model of career and academic counseling, provided by MBA(Master of Business Administration) alumni based social enterprise in Seoul. This service explores the skills, knowledge and capabilities which MBA alumni gained from their jobs and MBA programs within the context of a career-competency framework. This paper concludes with the social and educational aspect of this shared responsibility strategy that may enhance student motivation and persistence in non-urban high schools.

Until now, the strategies for increasing community participation has been focusing on the administrative legal institutionalization, but these have not brought substantive effects. So, the need of strategies utilizing the community culture which was formed by the residents and community has been issued on recently. The purpose of this study is to explore the strategies utilizing the community culture. So, it was identified the socio-demographic variables affected the community cohesion (community social networks, community solidarity, place-attachment), that is called community spirit and culture. And through path analysis, it was analyzed the relationship among residents' socio-demographic background, community cohesion, and community participation. The findings are as follows. : the community cohesion's three elements altogether affected positively to the community participation. When regarding the residents characteristics, the strategies for increasing the participation relating to community solidarity was most relevant. the socio-demographics affecting to community solidarity are gender, age, the beneficiary, religion, job type, household income, the length of residence. the women was low at level of participation. The most important variables affecting the community cohesion are the age, the residence duration. Based on these results, the relevant strategies or approaches for increasing community participation are as follows. : using and sharing of the aged's community knowledge, making the long term living and final settlement of community residents, increasing and creating the income for the low-income residents, increasing of religious organization and its members' responsibility to community, and the purposeful extension and relevancy of women's participation. Ultimately, this study is to contribute to fomulate the residents- cultural asset driven's community welfare planning.

It is necessary for undergraduate students whose citizenship reaches a maturity stage to recognize the importance of citizen participation in social issues related to science and technology and to be able to make meaningful use of citizens' rights and responsibilities. Therefore, in order to understand the actual status of undergraduate students' perceptions and practice capacity for citizen participation in science and technology, university students were selected from the department of arts physical studies (33 cases), humanities social studies (62 cases), and science engineering studies (67 cases) at D university in Gyeonggi province. Then, we investigated the scientific technology and society's interaction oriented by citizen participation, responsible decision-making ability, and the effectiveness of the social issue by scientific technology. Analyses of the results reveal that the overall perception level of the students about the interaction between scientific technology and society was high according to department of the arts physical studies, humanities social studies, science engineering studies, in that order, but the scores were not all in average. Therefore, it was found that the current undergraduate students lacked a deep understanding of the interaction between scientific technology and society regardless of the major field. In addition, the students' perception on citizen participation in the interaction between scientific technology and society was found to be problematic regardless of the major field. In responsible decision-making ability, undergraduate students were found to have difficulties in selecting the best alternative in terms of individual beliefs and welfare of others and formulating the action strategies. In addition, the self-confidence of the students about knowledge, skill, and capacity for action related science and technology in the effectiveness of the social issue by scientific technology was very low regardless of major field. We discussed educational implications of these findings.
