This research analyzed mathematical discourse of the students in an RME-based differential equations course at a university in order to investigate the social transformation of the students' conceptual model of differential equations. The analysis focused on the change in the students' use of conceptual metaphor for differential equations and pedagogical factors promoting the change. The analysis shows that discrete and quantitative conceptual model was prevalent in the beginning of the semester However, continuous and qualitative conceptual model emerged through the negotiation of mathematical meaning based on the inquiry of context problems. The participation in the project class has a positive impact on the extension of the students' conceptual model of differential equations and increases the fluency of the students' problem solving in differential equations. Moreover, this paper provides a discussion to identify the pedagogical factors Involved with the transformation of the students' conceptual model. The discussion highlights the sociocultural aspect of teaching and learning of mathematics and provides implications to improve teaching of mathematics in school.

This article examines not the term "the public" or "publics"-which has various meanings-but its particular meaning, which is a group of citizens who engage in political discussion and debate with fellow citizens in order to form shared understandings and common judgments with regard to contemporary affairs and public issues. The goal of this article is to show the importance of this concept in critical studies of media and society and to analyze how this concept has been accepted in South Korean critical communication studies. In this article, critical communication studies refer to communication studies that aim to explore social meanings of communication phenomena. This article argues that little attention has been paid to the concept of the public as agreement-oriented discursive political participants in South Korean critical communication studies.

The article attempts to suggest s a direction of science education in terms of development of creative human resources based on discussion about scientific literacy and scientific creativity. Students are supposed to develop scientific attitude, inquiry skills, problem solving ability through science learning, and be prepared for the 21st century of rapidly developing age. The paper introduces definitions of scientific literacy and scientific creativity and discuss their meanings within science education in general as well as for the gifted. To enhance students' scientific creativity, science education should strengthen content of science related to technology, integrated science content, personal and social views, social inquiry for problem solving. In particular, science education for the gifted should emphasize students' holistic views in interpreting data, ability to connect artistic aspects to science process, intuitions to explain scientific phenomena and pursue of personal satisfaction. It may be said that science education and science education for the gifted is realized when students have opportunities to experience such elements in their science learning.

The aim of statistics education is to enhance statistical thinking. Variability is the key components of statistical thinking. The research has been reviewed preceding research about variability of data. Proceeding from what has been considered above, this research developed learning materials that investigated the concept of variability as it relates to Freudenthal's context by having students sort a particular context. The research is executed the case study evidently aimed at Junior High School 3rd Grade Student's Understanding of Variability. The study of variability in data can be an important start to reach a testing of statistical hypothesis; students reduce data and draw graphs by relating probability distribution to relative frequency and normal distribution. Thus, this study offers basic materials into developing both contents and methods of education need to consider with this sense of purpose held by students to achieve this goal.

Seongri scholars of the Joseon Dynasty said that portraits were revered as academic teachers, and that the personal meaning was typical. Portraits in the latter phase of Joseon Dynasty have been popular in various contexts, especially in the sense of the texture, the religious church, and the ritual service. The etiquette and written aspects contained in portraits can point out the problems of contemporary society's individualism and attitudes through the expressive and personal approach to the art of painting. The purpose of education is to explore relationships with others, to coordinate myself with others, to have respect for others, and to change the inner workings of individuals. Through this, we can explore and explore personality education elements and find ways to achieve personality education through the exploration of figures using portraits as educational material, the process of making portraits, and the discovery of meaning. Therefore, for systematic appreciation, we are planning to set up an appreciation standard by proposing a 3-step review process applied to the 2015 revised education course.

The purpose of this study is to identify a domain-specificity of the scientific creativity and the component of scientific creativity. Conducted from theoretical study, this study suggests that a domain-specific view of creativity offers a more useful and constructive components of scientific creativity based on the literature associated with the component of scientific creativity. Scientific creativity has a domain-specific component and so there is need to distinguish scientific creativity from creativity in general. As a result, scientific creativity is different from other creativity it is concerned with scientific knowledge, science process skill, creative scientific problem finding and solving and so on. And since scientific creativity is a kind of ability, it is possible to improve through a scientific creativity program.

The increasingly severe environmental problems such as resource depletion and ecological damage, and consumers' concern for sustainable fashion, make the fashion industry chain develop towards green energy saving. The purpose of this study is to explore the attitude and consumption psychology of specific groups towards sustainable fashion consumption, as well as their specific views and attitudes towards recycled textiles or fabrics for re-manufacturing clothing. This paper attempts to understand how the characteristics of recycled clothing affect consumer. Based on the review of relevant literature, a series of determinants affecting consumer behavior is determined, and the characteristics of recycled products, such as expression value and social value, are determined. An online questionnaire was designed based on this conceptual framework, and 226 valid, complete answers were received. The results show that the emphasis on social value and environmental protection consciousness can effectively affect consumers' decision-making. These findings were helpful to the research of whole green environmental protection and ecological clothing recycling industry system, promote the sustainable development of the clothing industry.

This study aims to investigate the interrelationship between German expressionist dance and grotesque art, with a specific focus on the analysis of Pina Bausch's renowned work, <Café Müller>. German expressionist dance emerged as a response to the social instability and economic downturn that followed World War I, leading to the introduction of expressionism and grotesque aesthetics. The incorporation of grotesque expression in dance plays a critical role in boldly portraying the destruction of the human condition and its underlying causes, thereby offering insights into social contradictions and the erosion of human nature. This research thoroughly explores the intricate connection between German expressionist dance and grotesque expression, providing a comprehensive analysis of Pina Bausch's <Café Müller> to reassess the profound meaning and significance of expressionist dance. Additionally, this study delves into the inherent grotesque tendencies embedded within the work, surpassing conventional notions of visual beauty and ugliness, and strives to reinterpret the essence of grotesque expression through the nuanced movements of the dancers and the integration of auditory elements within the performance.

The purpose of this study is to examine the pre-service teachers' concept of measurement uncertainty. The subject of this study were 27 pre-service middle-school teachers in Seoul. They carried out open-ended inquiry tasks and surveyed two kinds of open questionnaires, and interviewed several persons. We analysed their behavior and responses. Through the analysis, we summarize pre-service teachers' concept about measurement uncertainty with representation data, precision and accuracy, error analysis, propagation of uncertainty. The results show that the teachers' concept is different from scientists' concept. They make a mistake in using term of precision and accuracy and pay no attention to measure precisely. Also they only point out sources of error but don't consider how the error affects the results of experiment. The results of study will give! 1 some implications for the curriculum and teaching material developers in order that pre-service teacher and student gain scientific concept.

The purpose of this study was to analyze pre-service teachers' reflective discussion on their practical work-based teaching by focusing on the components of instruction and the connectivity of discussion. Eight after-class discussions were recorded and transcribed, and finally analyzed in terms of theoretically driven categories such as aims, teacher knowledge and learner response which also respectively reflect the actual flow of planning, implementation and evaluation of the teaching practice. The result showed that in their discussion about students, conceptual understanding and scientific skill components were most emphasized, while teaching method and strategy were most frequently addressed in the discussion about teacher knowledge. But this also revealed problems in their discussions such as the lack of discussion about inquiry and student interest, difficulties in clarifying theoretical terms and the lack of discussion about instructional models and theories. Meanwhile, pre-service teachers' discussions were limited in terms of connectivity between the components of instruction, meaning that their discussion tended to deal with each component separately rather than occurred in connection with each other. Furthermore, when connections were made during the discussion, only few components of instruction appeared. Based on this result, the paper suggests the need to develop tools to facilitate effective reflection in ways that incorporate various components of instruction and enhance connectivity between the components and between the instructions.
