In this study, we investigated the characteristics of students participating in Science Core high schools classes and their relevance to Positive Experiences on Science (hereinafter, PES), and factors causing PES, presented by the students of Science Core high schools. A total of 20 students and five teachers in four regions across the country participated in the in-depth interview, which were conducted with the focus group of students first, and then in-depth interviews with teachers. Based on the interview results, we explored teaching and learning experiences helpful to the PES, assessment experiences resulting in the PES, and ways to support Science Core high schools to enhance their PES. Students and teachers of Science Core high schools argued that students' participation will increase only if they engage in classes while drawing attention within the range that students can understand, students' PES such as scientific interest can be improved through experiments in which students choose topics or design their own exploration process, science competencies such as science problem solving ability and scientific thinking ability should be developed through exploratory experiment activities that fit the nature of science, etc. In addition, regarding ways to improve and support Science Core high schools to enhance PES, securing science class hours, restructuring the contents of science elective courses, and necessity of maintaining Science Core high schools are suggested. Based on the research results of science high school students' PES, ways to improve the PES of general high school students are discussed.

This study explores the characteristics of within-school and across-school science teacher professional learning communities (hereafter, PLC) qualitatively. In-depth focus group interviews were conducted with science teachers belonging to seven PLCs within the science core school and three PLCs across schools. Interview questions include identity and motivation, major activities, and outcomes of PLC, as well as shortcomings and support plans for PLC. The results include both within-school and across-school science teacher PLCs formed for professional development related to science teaching and learning. Both science PLCs participated in the study showed the characteristics of a 'practice community' that developed a cooperative relationship through reciprocal participation, focusing on shared issues among members. Regarding issues, within-school PLCs focused on microscopic problems such as curriculum reconstruction of subject-matter, while across-school PLCs focused on macro problems such as teacher professional development. Regarding activities and roles as PLC, within-school and across-school science PLCs shared such features as collaborative professional development, and interpersonal education such as mentoring for novice teachers. In terms of PLC's influence and outcomes, science teacher PLCs has a positive effect not only on the teachers themselves, but also on the students and the teacher culture in the school. In addition, science teacher PLCs need improvement of the physical conditions for community operation, and software support such as protocol provision for PLC operation and joint research or re-education with universities. In particular, joint research between universities and science teacher PLCs shows the future orientation of the PLC as an 'inquiry community'. Based on the results, the necessity of active support for science PLC, the necessity of developing a cooperative system between science teacher PLC and universities, and ways to spread the PLC of science core schools to that of general schools were proposed.

The purpose of this study was to obtain a deeper understanding of didactic processing in the class that unified with engineering by analyzing on the types of the teacher's instumental orchestration and schematizing it as an activity system. In order to do so, a qualitative study of a 5th grade class for math-gifted students in Y elementary school with ethnography was conducted. Interviews with the students were held and various document data were collected during the participational observation of the class. The collected qualitative data were gone through the analytical induction while the instrumental orchestration of Drijvers, Boon, Doorman, Reed, & Gravemeijer as well as the secondgeneration activity theory of Engestrom were using as the frame of conceptional reference. According to the result of this study, there exist 4 types, such as 'technical demo' 'link screen board', 'detection-exploring small group' and 'explain the screen and technical demo'.

The purpose of this research was to investigate how the peer review activity of lab report in the problem-solving experiment effected on the description ability and the quality improvement. The students who were taking the general chemistry experiment course were the subjects for this study. They finished lab reports and received peer review from their peers more than two times. The students who got feedback answered on peer review, revised their reports, and subsequently, completed final reports. The result showed that peer review affected the qualitative improvement of the lab report, specially in the process of 'designing experiment' and 'drawing conclusion and evaluation'. Students could organize their thoughts through writing lab reports. During this process, peer review activities provided the opportunity of self-examination and the way for viewing as objective standpoint. Moreover, the activities established communication fields for exchanging mutual opinions and learning.

This study examines how scientists understand standardization and standardization policy in the Korean national R&D context and analyze future policy direction of standardization policy. Interview with 15 scientists at universities and government-funded research institutes who have participated national R&D (particularly in the field of technology convergence) were conducted. The results show that considerations of standardization at the process of technology convergence is somewhat different from them at the process of general R&D. Also, considerations of standardization at the process of technology convergence is needed at the later time within the R&D time schedule because of low visibility and forecasting on the technology convergence outcome. It finds that "standardization by private sector" is the future policy direction in Korea. The government needs to be remained as "helper" for private sector to lead standardization in a globalized market
