The purpose of this study is to develop an argument-based modeling strategy, utilizing writing and argumentation for communication in science education. We need to support students and teachers who have difficulty in modeling in science education, this strategy focuses on development of four kinds of factors as follows: First, awareness of problems, recognizing in association with problems by observing several problematic situations. Second is science concept structuralization suggesting enough science concepts by organization for scientific explanation. The third is claim-evidence appropriateness that suggests appropriate representation as evidence for assertions. Last, the use of various representations and multimodal representations that converts and integrates these representations in evidence suggestion. For the development of these four factors, this study organized three stages. 'Recognition process' for understanding of multimodal representations, and 'Interpretation process' for understanding of activity according to multimodal representations, 'Application process' for understanding of modeling through argumentation. This application process has been done with eight stages of 'Asking questions or problems - Planning experiment - Investigation through observation on experiment - Analyzing and interpreting data - Constructing pre-model - Presenting model - Expressing model using multimodal representations - Evaluating model - Revising model'. After this application process, students could have opportunity to form scientific knowledge by making their own model as scientific explanation system for the phenomenon of the natural world they observed during a series of courses of modeling.

Issues on climate change we are facing, such as global warming, are very important as it affects our lives directly. To overcome this, efforts to reduce greenhouse gases emissions (e.g., carbon dioxide) are necessary and these efforts should be based on our integrated understanding of carbon cycle. The purpose of this study is to examine the research trend on carbon cycle education and to suggest the value and direction of carbon cycle education for students who will be citizens of the future. We analyzed 52 carbon cycle education related studies collected from academic research databases (RISS, KCI, ERIC, Google Scholar, and others). As a result, we conclude that resources are still limited and more researches on verification and utilization of developed program, development of accurate and comprehensive tools for students' recognition and level assessment, developing educational model or teacher professional development, providing more appropriate curriculum resources, and the use of various topics or materials for carbon cycle education are necessary. Students' comprehensive understanding of the carbon cycle is important to actively react to the changes in the global environment. Therefore, to support such learning opportunities, resources that can be connected to students' daily experiences to improve students' understanding of carbon cycle and replace misconceptions based on the verification of existing programs should be provided in the classroom as well as the curriculum. In addition, sufficient exemplary cases in carbon cycle education including various materials and topics should be provided through professional development to support teachers teaching strategies with carbon cycle.

This study investigated the factors affecting the procedures of becoming a scientist. Interview was used as a research method for deep understanding of individual career choice procedures. Interviews for individual scientists were conducted for about 60 minutes in their offices and all the interviews were tape-recorded. A total of 34 scientists who received some representative science awards in Korea during 1990 - 2001 were sampled. They were all men. But the interview was conducted with 30 scientists. The investigation was based on the framework that was composed of the following four categories: personal ability, home environment, school environment, and sociocultural environment. And each category had several factors as follows: personal ability consisted of the meta-ability to figure out the aptitude and the self-ability and the achievement; home environment consisted of parents, brothers and sisters, relatives, and hobby; school environment consisted of teachers, friends, club activity; sociocultural environment consisted of event, mass media, social recognition and social prospect. From the analysis of the career choice procedure of the scientists it was appeared that the meta-ability for personal ability, the parental influence particularly by father for home environment, science teacher and professor for school environment, and social prospect for sociocultural environment were important. In conclusion, most of the scientists made an important decision for their future career when they were the 12th grade and 1st year in university, and they considered intrinsic factor such as self-interest and aptitude and extrinsic factor such as social prospect. However intrinsic factor related to science teacher and professor and extrinsic factor related to fathers' advice.

According to the Digi Capital forecast, the global augmented reality market is expected to grow rapidly by 2020 to reach 150 billion dollars. In particular, high value added effects are expected in education. As ICT advances, digital textbooks are also leading innovative education by adding interactive functions. Advanced countries, including the U.S., are already using digital textbooks that use augmented reality technology in their classes. In line with this technological outlook, the ministry proposed a design plan that applies augmented reality technology to middle school science 1 digital textbooks. A study on middle school science 1 digital textbooks showed that each unit provided short videos. In addition, an investigation into the augmented reality class case showed that it was difficult to establish experimental equipment, lack of equipment (devices), and 3D design contents that did not continue despite the excellence of learning effects. Based on this demand, we designed an augmented reality scenario and system configuration to be applied to the instrument-specific experiments of middle school science 1 digital textbooks to explore and explore the contents of augmented reality by students. This research will replace the dangerous experiments and time consuming experiments for teachers and students by applying augmented reality to science subjects that are essential for the development of digital textbooks.

If we, as educators, want to put students at the center of learning in science classroom, we must let students express their voices and exercise authority. To do this, we developed a classroom activity about 'Making a pet poster', and then we explored how elementary school students perceived their roles and expressed their authority during this activity. Fourth grade students from an elementary school in the city of Seoul participated in the activity, which was videotaped and recorded. We found that students expressed their epistemic authority differently in small group activities and in whole group discussions. In small group activities, they desired to show their authority as "pet experts" by using and selecting various resources from their everyday lives and transforming those resources into suitable forms in public spaces. Meanwhile, in whole group discussions, participants were classified as either presenters or audience members to verify their authority in regard to the pet poster activity; presenters desired to achieve recognition as "pet experts," and audience members assessed the presenters as "testers." In addition, they expressed authority as teachers by leading the whole group discussions. Based on these findings, this paper suggests the implications for new educational strategies to foster a student-centered learning environment.

The international standard for the school library suggests that school librarians qualified for librarian and teacher should run the school library. And library assistants should support the teacher librarian to carry out a role as a teacher. Despite the difference of requirements, librarians without teachers' license are under the human resources for school library administration. Furthermore, the job description between the school librarian and librarian is not well-defined in Korea. The different requirements in the library standards and the school library related laws have led to weaken professionalism and social status of librarianship. The condition that teacher librarians are not in the school library have brought the pressure to overcome imperfect functions of the school library and unfairness of educational services. In order to solve these problems, it is necessary to strengthen teacher librarians' qualification system to improve their identity as educational subject specialist librarians. We ought to also build proper foundations of social recognition about librarianship through classifying the types of human resources in the school library into the teacher librarian, library paraprofessional and volunteers. Especially we should hold the job analysis based on administrator, teacher, service, leader, collaboration, and partner.

The purpose of this study is to analyze current status and teacher librarians' perceptions of school library space composition and indoor environment, and propose some methods for the school library to be a basic educational facility. The space most secured by the 126 teacher librarians who participated in the survey was the free reading area, and the space with the lowest level was the media production and group project area. The most important types of spaces for teacher librarians are the teaching area and the free reading area, while the recognition of the importance of media production and group project areas is relatively low. Among the elements of indoor environmental assessment, they showed that safety and comfort were the most important but diversity and flexibility were relatively less important. The result of this analysis is different from the school and library policy direction that emphasizes the learning commons and maker spaces. Teacher librarians still seem to appreciate the importance of traditional library space. Therefore, it is necessary to include the establishment and operation of maker spaces and learning commons in the teacher librarians training and retraining process. In addition, it is necessary to increase the participation of users such as teachers, students, and parents in space composition and interior design initiatives to increase the user's interior environment satisfaction.
