This study aims to reflect the basic principles and teaching-teaming principles of Realistic Mathematics Education in order to suppose an way in which mathematics as an activity is carried out in primary school. The development of what is known as RME started almost thirty years ago. It is founded by Freudenthal and his colleagues at the former IOWO. Freudenthal stressed the idea of matheamatics as a human activity. According to him, the key principles of RME are as follows: guided reinvention and progressive mathematisation, level theory, and didactical phenomenology. This means that children have guided opportunities to reinvent mathematics by doing it and so the focal point should not be on mathematics as a closed system but on the process of mathematisation. There are different levels in learning process. One should let children make the transition from one level to the next level in the progress of mathematisation in realistic contexts. Here, contexts means that domain of reality, which in some particular learning process is disclosed to the learner in order to be mathematised. And the word of 'realistic' is related not just with the real world, but is related to the emphasis that RME puts on offering the students problem situations which they can imagine. Under the background of these principles, RME supposes the following five instruction principles: phenomenological exploration, bridging by vertical instruments, pupils' own constructions and productions, interactivity, and interwining of learning strands. In order to reflect how to realize these principles in practice, the teaming process of algorithms is illustrated. In this process, children follow a learning route that takes its inspiration from the history of mathematics or from their own informal knowledge and strategies. Considering long division, the first levee is associated with real-life activities such as sharing sweets among children. Here, children use their own strategies to solve context problems. The second level is entered when the same sweet problems is presented and a model of the situation is created. Then it is focused on finding shortcomings. Finally, the schema of division becomes a subject of investigation. Comparing realistic mathematics education with constructivistic mathematics education, there interaction, reflective thinking, conflict situation are many similarities but there are alsodifferences. They share the characteristics such as mathematics as a human activity, active learner, etc. But in RME, it is focused on the delicate balance between the spontaneity of children and the authority of teachers, and the development of long-term loaming process which is structured but flexible. In this respect two forms of mathematics education are different. Here, we learn how to develop mathematics curriculum that respects the theory of children on reality and at the same time the theory of mathematics experts. In order to connect the informal mathematics of children and formal mathematics, we need more teachers as researchers and more researchers as observers who try to find the mathematical informal notions of children and anticipate routes of children's learning through thought-experiment continuously.

The purpose of this study was to investigate the general transfer effects of Thinking Science program on the problem solving with compensational reasoning of the elementary school students. For this study, 156 5th grade and 138 6th grade students were selected from four elementary schools. The students were tested with SRT(Science Reasoning Task) and compensational reasoning task. Statistically significant gains on the development of compensational reasoning were shown by the experimental group implemented with Thinking Science activities compared to the group implemented with compensation activity only. The achievement of the experimental group was higher than that of the compensation activity group in solving problem with compensational reasoning, specially for the boys and students in both the mature concrete and the concrete generalization stage. The results of this study implied that implementation of Thinking Science program related to several formal reasoning were effective for the development of reasoning ability as a general-transfer.

Many misconceptions regarding biology and evolution have been reported by students prior to being exposed to a formal education program of evolution which challenged them. This study sought to investigate and to analyze the misconception formation process of evolution originating from TV animation and science books for children. Firstly, to identify TV animation's influence on students' misconceptions of evolution, a questionnaire including TV animation characters was constructed and administered to 146 elementary school students, 161 middle school students, and 156 high school students. The data collected was analyzed. Secondly, 17 science books for children were sampled and the contents related to evolution were selected and analyzed in terms of five evolutionary explanations: creationism internal will explanation, teleological explanations, explanations of use and disuse, mutation and finally, natural selection. Children have understood 'growth' and 'metamorphosis' on TV animation as 'evolution'. The processes by which characters on TV animation undergo some forms of change, which are in fact a kind of metamorphosis has often been understood as 'evolution'. Many respondents have defined evolution incorrectly as the process of growing and changing shape. On the other hand, some science books fur children contained descriptions of evolution including' mutation and finally natural selection explanation'; however, most of the science books fur children sampled in this study were written through the perspectives of alternative evolutionary views such as 'teleology view', 'internal will view', and 'use and disuse view'. It is apparent that TV animation and science books fur children influence the formation of various misconceptions regarding evolution by children.

This study was conducted to obtain a basic information related to a more systematic safety education and measures against children's accidents by a descriptive survey with regard to accidents actually experienced by elementary schoolers, their perceived safety education activities and school facilities to their safety lives. The data was collected among 1,654 pupils, belonging to the 5th and 6th grades in Pusan from Nov. 20 to Dec. 1, 2000. The data was analyzed using SPSSWIN(7.5). The results were as follows ; 1. According to the perception by elementary schoolers, they received safety life instruction at school in most cases from teachers in charge of their own class (41.0％). Such safety education was provided often during formal classes(24.4％). Traffic guidance was given by parents, highest in frequency(67.3％). 2. Matters as most often treated during safety life instruction were safety knowledge or dangerous things(37.5％). A majority of notices of school safety instruction were presented sometimes(48.4％). Source of knowledge about safety lives included teacher (35.3％), parents(32.9％), TV and newspaper (29.9％). As a source of knowledge of emergency treatment, school nurses were accounted for 41.3％ that was highest. 3.Among the 1,654 students, 91.8％ experienced at least more than one case of safety accident. The most frequent type and cause of safety accident were wound(33.7％). and self-carelessness(38.4％) respectively. In most cases, the subject experienced such accident during a break time(32.2％) and at a playgrounds. Part of body as most often damaged by accidents were arms and legs, 25.4％ higher than any other sides problem solving measures against the accident were taken by school nurse in most cases, 44.8％ in percentage point. 4. Those students' perceived safety management of school facilities showed that they considered classroom facilities as most safe (61.6％), while playground facilities as least safe(42.8％). They also responded that the treatment of glass fragments or stones at playground is the most important item of safety management.

The purpose of this study is to provide base line data to the educational settings so that more improved occupational core competencies could be taught under the formal curriculum of the technical highschool than before through the inquiry into 'the need for the consolidation of education that principals of technical highschool perceive'. Initial occupational key competencies had been prepared through the literature review on the occupational core competencies and the review on the key competencies by the experts in the field of technical industry had been performed to achieve the purpose of this study. The survey instrument consisting of final 9 occupational key competencies had been developed with the careful consideration for the calculation of the need for the consolidation of education using the Borich's model. The results show that principals for the technical highschool perceive the strong need for the educational consolidation regarding the all 9 occupational core competencies in the whole. However, for the specific key competency of understanding the organization and the mathematical competency, the principals of the technical meister highschool perceive somewhat differently from the principals of the specialized technical highschool. The principals in the meister highschool perceive not much need for the consolidation of education regarding the competency of understanding the organization and the mathematical competency.

Despite the importance of science education in an informal environment, the reality is that there is a lack of trend analysis research on 'Informal Science Learning (ISL)' and its effects. Therefore, the purpose of this paper is to find out the educational effects of ISL and how to use it, and to provide guidelines for future ISL research directions. This study classifies specific ISL-related papers published from 2010 to 2019 and compares them with each element of GLO used to measure the effectiveness of informal education. The fit of the analyzed data was checked for each part through SPSS and Chi-Square. In conclusion, it was found that researchers are using 'ISL' to pursue 'Knowledge and Understanding' and 'Attitudes and Values' among the five performance indicators of 'GLO'. On the other hand, 'Skills' and 'Enjoyment, Inspiration and Creativity' appear to have the least expectations, so supplementation is required in these areas in the future. In addition, this study intends to suggest a direction for informal science education-related program development and future research to various education workers.

Objective: The purpose of this study is to critically analyze the process of framing child abuse cases through the news coverage after the enforcement of mandatory CCTV installation policy which was initiated in 2015. Methods: The research uses the revised and supplemented frame analysis tools developed by Iyengar (1990) and Semetko and Valkenburg (2000) to investigate 25 broadcasting news reported by KBS, from September 2015 to December 2017. Results: First, according to the formal analysis, the reports on abuse cases prove to be either a mixed or episodic frame which covers the cases heavily based on a particular incident rather than holistically looks into the situation. Second, in content analysis, child abuse news is delivered mainly through "human interest frame." Conclusion/Implications: The study identifies three dominant discourses formed as a result of the child abuse CCTV news: 'CCTV is a all-around player' discourse, 'preschool teachers as potential criminals' discourse and 'preschool teachers as nonprofessionals' discourse. This study is significant in that it presents that mass media do not always say the truth, but frame social issues within an ideological delivery system.

The goal of this study is to explore and draw implicaitons from international and domestic media and information literacy (MIL) policies and educational systems. To this end, international policy documents issued by UNESCO, IFLA, OECD, and the EU as well as domestic South Korean laws and policies related to MIL and the fuctions of public libraries and related institutions were analyzed. The findings show that international organizations recognize public libraries as institutions that are responsible for providing information access and supporting knowledge sharing for citizens within and outside of formal education systems. Additionally, public libraries are seen as institutions responsible for supporting lifelong learning and civic education, as well as improving media, information, and digital literacy skills of their communities. In South Korea, the Library Act gives public libraries and librarians responsibility for improving citizens' MIL to support the public's right to know and to narrow the information gap. However, the functions of public libraries and librarians in South Korea have been limited or excluded in the domestic MIL policies. This study concludes that public libraries and librarians are responsible for reducing the information gap among citizens and should actively participate in policy development to improve citizens' MIL skills.

This study investigated how Korean elementary, middle, and high school students perceive mathematics learning situations to determine whether the mathematics classes provided in schools met the standards of a highquality educational experience. Using a comprehensive survey that considers both formal and implementation aspects of mathematics classes, responses from 15,418 students were analyzed to gain insights into their views on the classroom environment, instructional methods, and overall learning experience. The results indicate that as students advance in grade level, their perceptions of mathematics learning situations become increasingly negative, and mathematics classes are still perceived as being teacher-centered. Additionally, it was found that mathematical manipulatives and technological tools are not being effectively utilized, and that students' learning experiences are influenced by class size and the availability of mathematics subject-exclusive classrooms. Based on these findings, several recommendations were made to improve the quality of mathematics education and enhance students' perceptions: implementing teaching methods that increase student engagement in learnercentered classes, providing opportunities for active and diverse use of teaching aids and technological tools beyond simple calculations, maintaining appropriate class sizes, and expanding the use of mathematics subject-exclusive classrooms. These considerations are crucial for creating a more engaging and effective mathematics learning environment that aligns with evolving educational standards and meets students' needs. The findings of this study provide actionable insights for educators and policymakers aiming to improve the quality of mathematics education in Korea.
