This study investigated two science teachers' practical knowledge shaped during their science classes which intend to realize social construction of scientific models. The teachers' practical knowledge was qualitatively examined in terms of five content categories defined by Elbaz through the reflection-in-action based on video data of their teaching as well as the reflection-on-action based on their narratives and interview data obtained after their classes. The results shows: 1) two science teachers implemented their practical knowledge on appropriate subject matter knowledge when they provided students with scaffoldings to support building scientific models during the classes. 2) The teachers' knowledge about science curriculum played important roles to change the purposes of the classes from the transmission of difficult science concepts to the construction of scientific model appropriate to learning goals. 3) The teachers' implementation of pedagogical knowledge changed toward supporting students' group activities and model generations aligned to the intention of social construction of scientific models. 4) The teachers' practical knowledge about their 'selves' showed that a teacher's perception and implementation of his/her roles of helper, guide, or facilitator are important for students to construct scientific models through group activities. 5) The two teachers' practical knowledge the milieu of schooling is realized by their modes of interactions with student groups during their classes. Two teachers acted like a co-player with his students or like a coach to students near a playground. We discussed domain-specific characteristics about scientific model construction.

The purpose of this study was to examine the effects of an application of the experimental practice which is one of the performance assessments on student's science achievement and affective domain in the middle school science For this study, two classes were chosen from a co-ed middle school in Gimhae, and assigned to the experimental and the control groups. Prior to the instructions, a science achievement test and a affective domain test were administered. After the instructions, post-tests which were similar to the pretests were also administered. The results showed that the performance assessment based on an experimental practice was more effective of enhancing students' science achievement. However, there was no significant difference in an affective domain test between the two groups. For the control group, there was a significant difference between the pretest and post test in affective domain. It means that there was a negative change in affective domain of the control group.

Determinism and compatibilism have thought that libertarianism contradicts the scientific view. This paper demonstrates that the hypothesis that free will exists does not cause any problems and contradictions, while maintaining pro-scientific view. Rather, determinism lacks scientific and demonstrative bases. At first, I reject dualistic self by assuming identity theory of the self and physical body & brain. Free will is a functional concept or property that can have multiple realization. Therefore we can recognize whether aliens or robots have free will through observation on their acts. 'Free will' is a functional kinds term like 'digestion'. As we know we have digestive function, we can know that we have free will even before knowing the necessity of its existence by understanding micro structure of human free will. The judgement that an individual has free will function depends on whether it has particular actions. Those actions are controlling and restraining actions in context, predicting future, making elaborate conditional sentences, etc. Real being of free will is the physical occupant of the function that makes those actions. Determinism is based on various kinds of misconceptions and misunderstandings. Determinists often confuse necessity of physical law and determinism. Another decisive misunderstanding is that free will postulates same conditions and different results from the same point of time. However, free will postulates that the two points of time are different. Because determinism is unnecessary redundant hypothesis influenced by religions, according to Ockham's Razor, determinism should be eliminated.

The study in this paper considers how elementary school students' interest in mathematics and STEAM literacy could be promoted by conjoining the learning of mathematics with the learning of drone topics. Survey instrument was developed to measure student attitudes toward mathematics and science subjects and to evaluate student beliefs on learning mathematics embedded in science topics. Data were collected from elementary school students by administering pre- and post-tests: students were intervened with examples of math problems embedded in certain science contexts. The findings indicate that elementary school students' experience of solving mathematics problems embedded in science contexts positively affects the promotion of their attitudes toward, beliefs on science subjects and science and engineering career path selection. We hope that the mathematics program using the drone will be used in the classroom for STEAM.

Cyberspace is on its way to experience dynamic change, hereby encompassing technical and social diversities and multiplicities. The internet, with a history of no more than 10 years, has drastically changed the way, meaning and conduct of our lives, the structure and function of society and communication. Even in psychology, in which the purpose is to scientifically look into the human mind and explore its behavior, the in-depth inquiry into the human behavior and psychological features of the cyberspace have become an increasingly important issue. Research suggests that psychological features and concepts brought about during the process of communication in cyberspace have been influenced by the digital mode following the analogue one, and by the online mode following the off line one. It also suggests that, with new issues peculiar to information society, cultural structures should be re-conceptualized, reconstructed and reevaluated in various fields. This approach to the changing role, meaning and style within society should be rearranged and referred to as cyber psychology.

This study develops an informal science education program based on a creative design for the promotion of participation and action and explores the validity and effectiveness of the program. The program consists of three mini-projects, namely, The Martian: Surviving from the Mars, So Good to Have Seonjeongneung, and Designing a Sunshine Restaurant, with distinct topics focusing on the localization and contextualization of the region in which the program was implemented to encourage students' participation and action. The researchers selected three topics for each mini-project through discussions and revisions. The program is designed for 42 lessons across the three mini-projects and offers a presentation session in which students present their learnings from the program, constructed to facilitate personal contextualization. Participants included 15 elementary school students from Grades 5 and 6 who took surveys before and after the program. The pre-post surveys comprised two dimensions, 'Participation and Action' and 'Positive Experience about Science,' to examine the effectiveness of the program. At the end of the survey, we added a self-descriptive question that allows students to freely write down their feelings and thoughts. We checked the students' thoughts. The effectiveness of the program was illustrated by the largest increase in the "safe society" category, whereas there was little increase in other categories under the 'participation and Action' dimension in the Korean Science Education Standards. 'Science-related Self-concept' exhibited the largest increase, whereas the other categories displayed little increase from the 'Positive Experience about Science' dimension category.

Contemporary literary writers engage in multiple jobs and activities in the changing industrial and institutional environments to manage careers and produce literary value. The notion of art entrepreneurship envisages writers as the actors pursuing optimal rewards at both literary and economic levels by applying creative knowledge and skills to the management of career. In contrast, the notion of creative labor argues that writers go through career insecurity as they pursue self-fulfillment through work. This paper critically reviews two notions and suggests the notion of cultural intermediaries to better understand their production of literary value within the variety of relational contexts where they are situated. This paper analyzes the structures and characteristics of a wide range of intermediary practices by literary writers. Based on the analysis, I argue that the autonomy of literary value the writers construct and their status of entrepreneur-labourer are contingent upon the relational contexts within which they practice the intermediary work. I also suggest that literary writers by utilizing a variety of tactics cope with the changes that shape the autonomy of literature and invent new roles and identities as cultural intermediaries. Furthermore, literary writers develop not only self-management skills to adapt to the changing environments but also the collective capacity to cope with the constraints derived from the structural change of literary production and circulation. Finally, I argue that the art management discipline can reflect upon and support the creative endeavors of literary writers by embracing the critical understanding of structural changes suggested by the disciplines of humanities and social sciences.

Using open-ended questionnaires, two studies were conducted to explore social representations held by Korean undergraduates on children, adults and adolescents. Study 1 compared between children and adults with responses reported by 97 undergraduates(men: 28, women: 69). According to the results, characteristics of children distinctive from adults were basically personality-related and in particular, typical children were marked by high extroversion, low agreeableness, conscientiousness and culture. Further, happiness for both children and adults was determined mainly by interpersonal relationships, physical health and socio-economical status. However, good(or desirable) children characteristic of high agreeableness and conscientiousness were more similar to adults worthy of the name than to children worthy of the name. Using 57 undergraduates(men: 16, women: 41), Study 2 explored social representations of adolescents. The results indicated that overall adolescence were on the bridging state between childhood and adulthood. Happiness for adolescents, like both children and adults, was determined mainly by interpersonal relationships and socio-economical status. Finally, agreeableness, conscientiousness, self-, task- and relationship-related characteristics were involved in judging good(or desirable) adolescents. These findings were discussed in terms of features of Korean culture and human development.

Questionnaire data of 287 patrons of Tesco's Homeplus, Carrefour, Ermart, and Wal-rnart in the northern Daegu, Korea, using a structural equation model, were analyzed to investigate the hierarchical effects of values on discount store re-patronage intention as a measure of store loyalty, mediated by customers' evaluations of store associations. It was revealed that while customers' social affiliation value has a positive effect on store atmosphere evaluation, customers' self-actualization value has a positive impact on both after-sale service and employee services. It was also revealed that three associations such as access to a store, interior design, and employee services in their descending order have strong positive influences on the formation of customers' re-patronage intention. Theoretical and managerial implications are discussed in the conclusion.

In this study, we tried to develop STEAM integrated program using virtual reality(VR) equipment and to evaluate the learners' satisfaction in order to cultivate the convergent talent. The pre-test and the post-test were used to compare the mean scores of the assessed candidates and sub-areas. The post-test results were higher than pre-test results. The area with statistically significant mean height was derived as the 'self-concept' area of 'science' which is a sub-area of 'care and communication'.
