The environment subject has been introduced to the national curriculum in 1992 in order to overcome serious environmental problems. As using environmental issues in a class, the environment teachers inevitably face some conflicts associated with their role. By applying the questionnaire survey to 192 environment teachers, this study was conducted to understand their attitude and awareness of teacher role in the issue-based classes. The results showed that the majority(92.2%) of the participants had willingness to share their opinion on the issues under consideration with their students. This result implied that environment teachers maintain a position considerably different from the position (value-free and fair) that has been favored and suggested by previous research. This discrepancy may has been related to the unique history and identity of the environment subject in Korea. Despite their high level of willingness, the environment teachers also seemed to experience several barriers to managing issue-based classes effective such as time management, low students interest, and limited teaching materials. To make environmental issue-based classes interesting and meaningful, additional efforts are need to develop issue-based teaching modules and provide both teachers and teacher students with opportunities for learning those modules and teaching strategies.

The charging of 10-nm-class nanoparticles in an electrostatic precipitator (ESP) according to particle charging ratio has been investigated and compared to the diffusion effect of the nanoparticles. The competition between the charging probability and the diffusion loss effect determines the collection efficiency of nanoparticles in the ESP. The collection efficiency of nanoparticles decreased continuously with decreasing particle diameter. This indicates that the partial charging effect of 10-nm-class nanoparticles is more dominant than their diffusion loss effect in the ESP for nanoparticles in the particle size range of less than 10 nm. The charging ratios based on unipolar diffusion charging calculations were in good agreement with the experimental collection efficiencies for nanoparticles less than 10 nm in diameter.

The purpose of this study was to develop the environmental sensitivity(ES) measurement instrument and to apply for middle school students. The questionnaire was developed to evaluate ES. The developed questionnaire consists of 15 items in 5 categories. Each item of the instrument was developed through the conceptional analysis of the definition of ES. The 5 categories included natural environment, activity at natural environment, artificial environment, environmental pollution, environmental destruction. Data for this study were collected from 397 middle school students including 46 environmental class and 351 non-environmental class students. It was found that the developed instrument to measure ES was valid and reliable. Reliability coefficient, Cronbach $\alpha$ was 0.75. Using the developed instrument of ES, the ES was measured for the students of experimental group to which a inqury-based EE model was applied. The result was that the effect of ES of the students of the experimental group was not statistically significant. Futher research is needed related to the EE model based on the inquiry learning model and measurement of environmental sensitivity.

The purpose of this study was to analyze qualitatively implementation in schools through perception on creativity and character education of teachers who participated in winter training and workshop which the Southeast Regional Center for Creativity and Character Education arranged. The results are as follows. Firstly, teachers responded that they used most often a variety of students' experiential and participant activities associated with the subject in practising creativity and character education. Secondary, they showed a wide variety of responses from 'not to able to measure' to 'to practice in every class' for how often to apply to and practise creativity and character education in class. Thirdly, for the question of 'How do you think environment for creativity and character education in your school', while parts of them responded 'sufficient educational environment', some of them did 'poor or not completely supported environment'. Lastly, most of them utilized teaching materials for creativity and character education periodically or in reconstructing according to instructional form in their class.

The decrease in population of school age is one of major influencing factor of transformative educational environment. After the nineteen eighties, the population of South Korea has increased step by step, but the population of school age has been decreasing rapidly by low birth rate. As a result, closed school by merger and abolition of small school occurred all over the country. The closed school needed effective function as center of local community. Consequently the purpose of this study is to provide basic data for effective policy making of closed school by comparative analysis of educational environment such as number of students, schools, students per class, status of usage of closed school of the east area and the west area divided by The Tae Baek Mountains in the Gangwon-do, which has the least students in the nationwide. The results of this study are summarized as follows: 1) Gangwon-do has high decreasing rate of population, schools and students compared with other provinces. However it has significantly low number of students per class. 2) The number of students, schools of the west area in Gangwon-do outnumbers that of the east area. However the number of students per class of the east area in Gangwon-do lesser than that of the west area.

Objective: This study aims to explore the intra-action between infants and picture book reading in a daycare setting, aiming to gain new insight into infants' reading experiences. Methods: The participants in the study were 12 infants from the Bluebird Class (1-year-old) at A Daycare Center. To comprehensively examine the context and flow of the infants' experiences, participant observation was conducted during free play sessions, held three to five times a week, in the morning, from December 19, 2022, to February 17, 2023. Results: Firstly, infants engaged in the intra-action with symbols such as text, images, lines, colors, and latent narratives in picture books, spontaneously encountering meaning-making. Secondly, they explored the potential of materials such as their own bodies, the dacare classroom environment, and blocks, creating narratives through the process of 'becoming'. Thirdly, infants generated shared experiences by creating interactions within their relationships with others in the daycare class. Conclusion/Implications: This study highlights a shift in perspective, recognizing infants as active readers who construct their own understanding. Additionally, it underscores the significance of cultivating an infant-centered environment and the meaningful role of teachers in supporting and facilitating such an environment.

The purpose of this study is to determine the effects of CMC-based English learning. In this study, CMC components were found to provide circumstances of facilitating interactions between student-student and student-student-teacher, which enabled students to accomplish language learning tasks. Findings of this study are as follows: First, CMC based language learning experience helps students have positive attitudes toward their English language learning. Second, student-student-instructor interaction group outperformed other groups in academic achievement and class activity participation. Third, cooperative learning groups more actively participated in the class activity than the individual learning group resulting in better academic performances. These findings supported the fact that cooperative learning with CMC components are useful in bringing more class participation and positive attitude that were believed to foster language learning than other groups in traditional language learning environments. This study suggests that the instructor needs to use instructional design strategies helpful to facilitate active interactions between instructors and students in order to achieve better effectiveness of English learning in a CMC based learning environment.
