The purpose of this study is to investigate the meaning and process of scientific observation. Hence, this study reviewed and discussed meanings and process of scientific observation described in philosophy, the philosophy of science and science education. Major researches on scientific observation are focused on a characteristic and type of scientific observation behavior. These research can suggest what is the characteristic of observation facts generated by observer. But it cannot show what is the meaning and process of scientific observation, it should be provide to students. According to the result in this study, scientific observation is affected by observer's subjective factors, such as experience, background knowledge, interpretation(not inference) and observation skill. All factor are integrated as an intellectual framework, and it is able to be changed by the observed facts. On the other hand, inference is excluded on scientific observation, but it have constantly affect on intellectual framework through feedback. This study on scientific observation provides a scaffold in various activities of scientific observation to be provided to students.

The purpose of this research was to find out if the analogical role-playing class activity had an effect on the students' academic achievements on cellular respirations as well as their science learning motivation for those who took part in the cellular respiration. To examine the effects of applying the activity, the research was conducted targeting a high school with humanities and social sciences courses, located in Busan. The target was specified as two classes that had selected a Biology II class, with one class (27 students) set as the test group and the other class (28 students) set as the control group. The conclusion drawn from this research was as follows: First, it seemed that the analogical role-playing activity helped the students to take their own parts in cellular respiration and gave them an opportunity to explain the concepts through direct physical activities, enhancing their academic achievements. Second, it was concluded that as the students found confidence and relevance in scientific knowledge as well as obtained a sense of accomplishment, the analogical role-playing class activity increased their level of satisfaction and their science learning motives. Third, as a result of the interviews on the change of the concept, students expressed some dissatisfaction over the new concept, and thought of the analogical role-playing activity as an intelligible alternative. It appeared that the alternative was plausible and fruitful.

The purpose of the study is to explore the science teaching orientations of secondary science teachers, and how they influence the planning and execution of reform-based lessons. Professional development workshop for constructivist teaching consisted of three different phases; five lectures, small group discussion, and preparing lesson plans. Four teachers who participated also executed their lesson plans in their own classroom. All workshops were videotape recorded. Classroom observations and interviews were conducted and recorded. Instructional materials were also collected for each science class. All data recorded were transcribed and analyzed. Based on the data collected from multiple sources, we identified each teacher's teaching orientations, and through this lens, we also tried to understand their classroom practices. We expected teacher-participants to implement constructivist science teaching. However, the differences among teachers in the course of actual planning and implementing activities for constructivist science was wider than we expected and even some teachers were unsuccessful. Teaching orientations can act as a filter for teachers when they decide whether to accept and apply new knowledge about teaching and learning to actual lessons or not. Even if a teacher plans a guided-inquiry lesson, her/his didactic teaching orientation could be revealed in actual classroom, and lead her/his class to other direction which is quite different from her/his original intention. Although the teachers participated in the same workshops in our study, they planned and executed differently and their own teaching orientations contribute substantially to their practice. Understanding the role of science teaching orientations could be an important step in addressing issues of diverse difficulties in supporting reform efforts in science.

Reflection in teacher education is one reform effort that has taken hold in many teacher preparation programs. However, how to define it and how to foster it in a teacher's education are problematic issues. In this study, on the basis of literature review, science teachers' reflective thinking is defined as a process of thinking that deliberates on alternatives to solve conflict between one's previous knowledge/belief/practice and internal/external factors in science teaching context. Based on this definition, three types of science teachers' reflective thinking (i.e. technical reflection, professional reflection and critical reflection) were proposed. In addition, a framework of classifying the reflective thinking's types was also developed. To investigate science teachers' reflective thinking, two pre-service science teachers who majored in physics education participated in this study. The participants presented the monthly report on reflective practice, pre/post questionnaire, and education practicum journals. Individual interviews with them were conducted before and after their teaching activities. From the analysis of the data, it was possible to categorize the reflective thinking of the participants into three types. The major type of their reflective thinking was the technical reflection. However, it was difficult to find examples of the critical reflection.

The purpose of this study is to gain an understanding of scientifically gifted students' views on the nature of science. A multiple-choice format questionnaire was administered to 237 Korean 10th, 11th and 12th graders at the Korea Science Academy. The differences and similarities by gender and experience of R&E program on the students' views of the nature of science were investigated. The questionnaire developed by Lim(2004) was implemented for this investigation. We found that the majority of scientifically gifted students had highly possessed the tentativeness of scientific knowledge. The students who experienced R&E program have relatively high apprehension of scientists' motivation for researches and activities in social context compared to the students who did not experience an R&E program. Scientifically gifted students had relatively high apprehension that government should not control researches of scientists and relatively low apprehension of social responsibilities of scientists comparing to general high school students. The experience on R&E program was identified as a factor to effect changes in the students' views on the nature of science. The study has implications for the development of gifted program and curriculum such as running and assessing R&E program, and also the pre-service preparation of science teacher, teacher education reformat in both the practical and the policy levels.

Modem science education was introduced to Korea in the enlightenment period. The science textbooks which were published at that time were important to modem science education in Korea. Therefore, the translators and publishers of science textbooks were the leader of the science education in the enlightenment period. Hyun Chae and his son as a translator were one of the leaders in science education at that time. Hyun Chae was born to a Middle class (中人)family and succeeded to pass the national examination for translators (譯科). He worked as a translator and author at the Ministry of Education (學部). Also, he was the associate teacher in a foreign school and the Hansung normal school (漢城師範學校). He published 26 books. One of them, Rikwa (理科) as the science textbook covering all the areas of science, physics, chemistry, biology and earth science. That presented the knowledge, which students should know by proper method, induced students' interest and included various experiments. Hyun Chae's activity in science education as the author and translator of science textbooks was an important role on the forming science education in the enlightenment period because it was caught short of science textbooks. The author, translator, and publisher of science textbooks was of great significance to make science popular, which was the new culture. Therefore, the role and activities in science education of Hyun Chae was a part of the history of science education, he knew a foreign language and was the leader in facilitating exchange with foreign countries.

With strength training comes the risk of injury and the benefits of exercise. Lack of knowledge and experience or repetitions at excessive intensity can lead to injury. Adequate feedback on an exercise's progress can increase the exercise's effectiveness and reduce injuries by providing scientific data and psychological motivation. This study aimed to validate EMG equipment and examine the effects of 8 weeks of biofeedback training with wireless electromyography. A correlation analysis between the Noraxon device and Fitsig®(EMG Prototype), a well-known instrument in the field of research, showed a moderate correlation. Statistically significant differences in humeral circumference, humeral muscle mass, and biceps and triceps strength were found between the left and right sides of the body over time, with no differences in the type of exercise. Feedback training with real-time EMG was found to be favorable for hypertrophic growth and strength improvement. Future studies should be conducted to investigate its application in sports activities further.

This study aimed to investigate the impact of scores on the Test of Proficiency in Korean (TOPIK) among foreign exchange students on academic adaptation. Recruited students, approved by the Institutional Review Board (IRB), totaled seven, and their interview contents were analyzed using a comprehensive analysis procedure based on pragmatic eclecticism (Lee, Kim, 2014), utilizing six stages. As a result, factors influencing academic adaptation of Korean language learners for academic purposes were categorized into three dimensions: academic, daily life, and psychological-emotional aspects. On the academic front, interviewees pointed out difficulties in adapting to specialized terminology and studying in their majors, as well as experiencing significant challenges with Chinese characters and Sino-Korean words. Next, from a daily life perspective, even participants holding advanced TOPIK scores faced difficulties in adapting to university life, emphasizing the necessity of practical expressions and extensive vocabulary for proper adjustment to Korean life. Lastly, within the psychological-emotional dimension, despite being advanced TOPIK holders, they were found to experience considerable stress in conversations or presentations with Koreans. Their lack of knowledge in social-cultural and everyday life culture also led to linguistic errors and contributed to psychological-emotional difficulties, despite proficiency in Korean. Based on these narratives, the conclusion was reached that in order to promote the academic adaptation of Korean language learners, it is essential to provide opportunities for Korean language learning. With this goal in mind, efforts should be directed towards enhancing learners' academic proficiency in their majors, improving Korean language fluency, and fostering interpersonal relationships within the academic community. Furthermore, the researchers suggested as a solution to implement various extracurricular activities tailored for foreign learners.

The current debate in the academic community is on the criteria for predatory journals. Researchers are perplexed about what constitutes a predatory journal. The purpose of this study is to investigate how South Korean researchers discover and evaluate predatory journals. In order to achieve this, we collected 2,484 statements, comprising posts and comments, from Korean researcher communities, namely the Biological Research Information Center (BRIC), Hibrain.net, Phdkim.net, and the Scholarly Ecosystem Against Fake Publication Environment (SAFE). We divided the data into three primary categories-journals, publishers, and researchers-for the topic analysis. For each statement, we assigned 11 in-depth subtopic tags based on these categories. Six main points of contention emerged from the combinations of these sub-topic tags: (1) researchers' confusion about predatory journals and discussions about research performance; (2)(3) researchers' positive and negative perceptions of predatory journals; (4) researchers' evaluation criteria for journal quality and problems associated with the quality of Korean journals; (5) changes in publishing brought about by the introduction of open access (OA) and associated issues; and (6) discussions on broader issues within the academic ecosystem. By using a qualitative approach to examine how South Korean researchers view predatory journals, this study aims to advance basic knowledge of the discourse around them in the communities of domestic researchers.
Growing complexity in ecosystem structure and functions, under impacts of climate and land-use changes, requires interdisciplinary understandings of processes and the whole-system, and accurate estimates of the changing functions. In the last three decades, observation networks for biodiversity, ecosystems, and ecosystem functions under climate change, have been developed by interested scientists, research institutions and universities. In this paper we will review (1) the development and on-going activities of those observation networks, (2) some outcomes from forest carbon cycle studies at our super-site "Takayama site" in Japan, and (3) a few ideas how we connect in-situ and satellite observations as well as fill observation gaps in the Asia-Oceania region. There have been many intensive research and networking efforts to promote investigations for ecosystem change and functions (e.g., Long-Term Ecological Research Network), measurements of greenhouse gas, heat, and water fluxes (flux network), and biodiversity from genetic to ecosystem level (Biodiversity Observation Network). Combining those in-situ field research data with modeling analysis and satellite remote sensing allows the research communities to up-scale spatially from local to global, and temporally from the past to future. These observation networks oftern use different methodologies and target different scientific disciplines. However growing needs for comprehensive observations to understand the response of biodiversity and ecosystem functions to climate and societal changes at local, national, regional, and global scales are providing opportunities and expectations to network these networks. Among the challenges to produce and share integrated knowledge on climate, ecosystem functions and biodiversity, filling scale-gaps in space and time among the phenomena is crucial. To showcase such efforts, interdisciplinary research at 'Takayama super-site' was reviewed by focusing on studies on forest carbon cycle and phenology. A key approach to respond to multidisciplinary questions is to integrate in-situ field research, ecosystem modeling, and satellite remote sensing by developing cross-scale methodologies at long-term observation field sites called "super-sites". The research approach at 'Takayama site' in Japan showcases this response to the needs of multidisciplinary questions and further development of terrestrial ecosystem research to address environmental change issues from local to national, regional and global scales.
