The aim of the present study is twofold. One is to confirm a hypothesis that a student's rate concept influences her conceiving change of a function in the view of rate of change and the other is to build up foundations for understanding the transition process from her rate concept to the concept of rate of change when she investigates the change of concentration as an intensive quantity. We explored how three participating high school students recognized and expressed change of given functions by using their rate concept as a conceptual tool. The result indicates that a change in students' rate concept might have an effect on understanding how function values change in term of rate of change. We also expect that it could be a catalyst for further research for clarifying the relationship between students' rate concept and their development of a concept of rate of change as a foundation for learning calculus.

Space design in the 21st century has been developed in connection with media more various than ever. In the age of image represented by popular culture, space design connected with media is based on post-reason thoughts constituting the post-modern society, and reflects polysemously and pluralistically changes in the society through the identification of art with life. The movie, which is an image perceived particularly sensibly and the most impractical simulated image among various illusionary media images composing the contemporary society, is growing rapidly in interrelation with various fields of art based on its peculiar nature, and its influence is getting more extensive. The movie manipulates mass society to create what does not exist and restore lost images into new realities through the reproduction of extremely realistic senses, and uses them in establishing virtual realities and creating illusionary images representing the age of simularc. The illusionary expression of the movie produces new meanings through disintegrating existing meanings and recombining them, and expresses popular culture from a position closest to our everyday life. Such an analytical attitude toward the illusionary movie reflecting our society can be a new approach to space design. The present study attempts to suggest the possibility of applying such an illusionary characteristic of the movie as a methodology of space design by utilizing the characteristic as a conceptual language of space design.

Under the production system of a free market economy, the modern consumers'goods that feature current trends reveal diverse aspects of the whole society and culture. This phenomenon is progressing at such a rapid speed that theories can barely keep up to explain it dearly. It is believed that the reason for the lag in academic theories is the formation of pluralistic values in human lifestyles due to the development of science and information communication. The pluralism of values in contemporary society is being studied in many academic fields, and the design among these fields often sees such a phenomenon as one of the post-modernism concepts, where post-modernism suggests a diversification and dismantling of modernism. In other words, the current design is closely watching products that are totally different from existing products, from complex and conceptual outcomes in the field of design to products that reflect various trends. Thus, it is true that package design, which proactively reflects current trends, freely traverses among specific domains of various fields that have been determined tacitly. It is also believed that other fields are also reflecting the same developments. Such a phenomenon is strikingly revealed with so-called 'fancy products', while other products 'parody' package design. This study sees the phenomenon as dismantling the border between product design and package design. The examined package design reflects the broader characteristics of the times, based on current concepts and meanings, after reviewing design examples.

The routinized tasks in the post-COVID era are to be replaced by digital technologies, while there is a high possibility that digital transformation technologies and non-routinized tasks have strong complementarity. In particular, looking at the job composition within Korea's industries, the intensities of routinized works appear to be continuously rising. It suggests that the potential side effects on the labor market caused by the acceleration of digital transformation in the post-COVID era will be greater within Korean innovation system. With this background, this study aims to provide a conceptual framework for dealing with potential crises such as, job polarization and widening gaps between workers in terms of economic earnings, based on an in-depth understanding of the inherent properties of digital transformation that will lead to structural changes in our economic and social system. In particular, focusing on the interaction between digital transformation technology and learning in the post-COVID era, this study attempts to redefine the role of the innovation policy for making a successful transition to a new equilibrium state. In addition, this study examines the institutional conditions of the Korean innovation system which affect the creative learning activities of economic actors to draw policy implications for establishing future-oriented innovation policy. Based on these approaches, this study highlights the importance of coevolution between the skills demand and skills supply to spur inclusiveness of Korean innovation system in the post-COVID era.

In this study, a student participation-centered class based on student mathematical thinking as a the meaningful subject was called a student thinking-based math class. And as a way to support these classes, I paid attention to lesson design. For student thinking-based mathematics classes, it is necessary not only to anticipate student thinking and teacher feedback, but also to plan in advance how to properly arrange and connect expected student responses. The student thinking-based lesson design template proposed in this study is a modified three-step(introduction, main topic, summary) lesson design template. The reason for revising the existing design template is that it has limitation that it cannot focus on mathematical thinking. Using the conceptual framework of student thinking-based mathematics lesson as a lens, the difference between the three-step lesson design prepared by pre-service teachers and the students' thinking-based lesson design prepared by the same pre-service teachers was analyzed. As a result of planning lessons using the student thinking-based lesson design, more attention was paid to the cognitive and social engagement of students. In addition, emphasis was placed in the role of teachers as formative facilitator. This study is of significant in that it recognizes the importance of classes focusing on students' mathematical thinking and provides tools to plan math classes based on students' thinking.

This is an action research study of mixed methodology design to confirm the implementation process and effects of applying visual thinking and window paning on improving nursing ethics and professional courses. Based on the conceptual model for action research, a quantitative and qualitative approach was taken. The data was collected and analyzed in an integrated manner. The survey analysis was done using the SPSS WIN 23.0 program. The participants were interviewed after experiencing the techniques in class and content analysis was used on the answers. As a result of applying visual thinking and window paning, ethical decision-making confidence (t=6.748, p<.001) and nursing professional intuition (t=-3.52, p<.001) showed statistically significant changes. There was, however, no significant change in biomedical ethics consciousness (t=1.291, p=.199). Qualitative analysis found that they had fresh experience, an unfamiliar but comfortable feeling, feeling of being mine, insufficient time, systematic case study approach based on theory, were able to cultivate cooperation and coordination ability through discussion and experience in various professional fields, pride, ethical responsibility consciousness and were able to apply learning content in the field. Visual thinking and window paning foster diverse competencies in nursing education and help integrative learning. Therefore, based on the results it is proposed that visual thinking and window paning are applied to the improvement of instruction in other courses to develop core nursing competency.

The purpose of this study was to have a phenomenological understanding of the experiences in the marital relationship after the first baby is born. For this purpose, thirteen couples (marriage duration of less than five years; within three years of the child birth) were recruited and semi-structured interviews were conducted. The interview data were analyzed through the open coding, axial coding, and selective coding. In the next step, we derived the marital relationship paradigm after the first baby arrived. The causal/situational conditions that caused changes in the marital relationship were the parenting burden and the marital adjustment level. The central phenomena were parenting and housework burden, which were moderated by the husbands' support. The action/interaction strategies were couple's high awareness and acceptance for their new role and pursuit of the shared meaning of the family. When the strategies were successful, a deeply satisfying feeling and shared values could be obtained. Finally, we identified the core category to integrate of other categories into a conceptual framework, and that is 'the awareness and acceptance for their new role and the pursuit of a sense of We-ness'.

While scientific explanation is a fundamental component of science, teachers often lack familiarity with the formal structure of scientific explanations and the criteria for assessing their quality. Consequently, this study aims to clarify the concept of scientific explanation and proposes a tool for constructing scientific explanations. The primary objective is to explore the tool's impact on enhancing the explanatory skills of pre-service teachers when it comes to the phenomenon of condensation. The research findings indicate that many pre-service teachers initially operated at a description level during the pre-test. However, the implementation of the tool enabled them to advance their explanatory skills beyond the associative level. Notably, the tool was analyzed for its ability to provide pre-service teachers with a conceptual framework for explaining phenomena and guiding logical explanations and micro-level interpretations. This study holds significance in demonstrating that pre-service teachers can comprehend the formalities and criteria of scientific explanations and apply them to enhance their own explanatory abilities. Moving forward, efforts should be made to enhance the scientific explanation level among pre-service teachers across various topics and subject areas. Furthermore, pre-service teachers need classroom experiences that foster the construction of scientific explanations in authentic contexts.

J. J. Schwab is usually considered as the founder of the concept of scientific enquiry, perhaps the most important key word of science education of the 20th century. Mainly through the method of literature review, this study reappraises Schwab's life as a science educator as well as a curriculum scholar, and his ideas concerning several important issues about science and science education. Like other eminent science educators, before the 1950s, who were originally talented scientists but later became engaged in educational activities, Schwab were trained and known as a genetic scientist, but later he concentrated on university reform, curriculum studies and science education. His academic interest was very diverse across different disciplines, from biology and science in general to history, philosophy and education. The essence of his theory of scientific enquiry was 'to teach science as science', and the best way to do it was 'to teach science as enquiry'. With enquiry, however, he tried to deliver some important but differentiated meanings, for example by distinguishing 'science as enquiry' and 'teaching as enquiry', and 'static enquiry' and 'fluid enquiry'. Scientific enquiry was the core concept upon which many of his ideas concerning science education and education in general were based, such as the diversity of science, textbooks, curriculum and roles of teachers. In summary, Schwab can be characterized as a rational reformist of science education, who tried to identify the very nature and goals of the discipline and to bring its substantial changes with concrete and practical guidelines. Nevertheless, some of his ideas, like the diversity of science and conceptual invention, have been handed down by his followers frequently with considerable distortion.
