The purpose of this study is to investigate science teachers' orientation toward scientific inquiry-based teaching. In this study, five middle school science teachers formed and participated in a teacher learning community for scientific inquiry-based instruction during one year. Data collection consisted of pre and post questionnaire and interviews, audio-recordings of teachers' collaborative lesson planning and reflection on teaching practice, and field notes of participant teachers' teaching practice and follow-up interviews. Data analysis indicated that there were four orientations toward scientific inquiry-based teaching. They were knowledge and beliefs about 'goals of scientific inquiry-based teaching', 'scientific inquiry-based teaching and learning', 'argumentation-based teaching and learning', and 'nature of science and science inquiry'. Teachers' collaboration in a teacher learning community would be effective in facilitating teachers' orientation to scientific inquiry-based teaching.

The era of the Fourth Industrial Revolution calls for creativity - convergence talent. In addition to having mathematical knowledge, they can create new technologies by linking them to other fields. This social trend is also reflected in the 2015 revised curriculum, and plans to further expand the STEAM education emphasized since 2011. Many teachers who had previous experience with STEAM training were satisfied with the STEAM teaching effectiveness. However, the reality is that the lack of expertise in other subjects is causing a burden on the ongoing implementation of convergence education. One way to alleviate these teachers' burden is to find the STEAM elements and then apply. Since the convergence education is required continuously, it is necessary to analyze the textbook according to the 2015 curriculum. In this study, we examined how the elements of the STEAM were apply in 7th grade textbooks. Based on the classification framework proposed by Yakman (2008), a new classification framework was devised and applied to the analysis.

This study utilized latent growth curve modeling to investigate the trajectories of adolescent life satisfaction changes in middle and high school students. The effects of self-esteem, career identity, school learning activity, gender, and household earnings on life satisfaction changes were examined. Data was obtained from the Korea Child Youth Panel Survey (KYCPS), a longitudinal study following students for 7 years. Year 3-6 data was utilized. Results found that the life satisfaction trajectory resulted as a quadratic model in which individual differences were significant. Second, school learning activity used as a time variant variable had a positive significant effect on life satisfaction each year. Third, gender and self-esteem as time invariant variables had significant effects on initial levels while self-esteem had effects on the slope and quadratic change. Further implications and research issues are discussed.

The free learning semester system focuses on the activation of career education of middle school students as an educational policy that links career recognition in elementary school, career search in middle school, and career planning in high school. This system was fully implemented in 2016 and public libraries also provided various programs. This study analyzed the free learning semester system programs of public libraries in Busan city and demonstrated the contribution of local development. As a result, career and job search, career exploration and experience, and information literacy enhancement programs contributed to local knowledge culture, reading culture, learning culture, living culture and leisure culture. However, contribution of reading exhibitions, job experience, information literacy enhancement to the leisure culture and local economy were limited. Therefore, it is desirable that all libraries should add programs related to knowledge ecosystem structure, digital information gap, human healing, social environment issues, future job prospects, and provide information literacy programs.

The purpose of this study is to analyze the effect of the perceptions of school violence and satisfaction after violence prevention sociodrama in the first grade of middle school. This study was carried out in April, 2018, and the experimental group and the control group were 12 students in each of the first grade of middle school in S city and A city. As a result, the level of perceptions of school violence in the experimental group was 14.50 in pre-test, 11.83 in post-test, and 9.33 in average rank. The level of perceptions of school violence in the control group was 14.25 in pre test, 13.83 in post-test, and 15.67 in average rank. The Mann- Whitney U test between the two groups showed statistically significant indicating that school violence prevention programs are effective. The program has been satisfaction in the experimental group and the total average is very high as 4.71 out of five points, in particular the highest satisfaction with 'teacher's class progress'. Through this study, it is expected that the diffusion and spread of school violence prevention sociodrama for middle school students.

The point of this research is verifing the longitudinal changes in youth multicultural acceptance and to verify predictive variables of multicultural acceptance. Among the Korean Children and Youth Panal data collected by the Korea Institute for Children and Youth Policy, 1,972 data from the 3rd, 5th, and 6th data of the first-year middle school panal were used, and the data were analyzed by applying the latent growth model, and the following analysis results were obtained. First, adolescents' multicultural acceptability showed an increasing pattern, and the extent of the increase was large at the point of transition from the 3rd year(3rd year of middle school) to the 5th year. Second, predicting the change of multicultural acceptability were found to be significant in the initial values of peer communication, community consciousness and in the rate of change, life-satisfaction, peer communication, community consciousness. This study proposed some plans to improve multicultural acceptance in adolescence basing on these results.

The purpose of the study is to examine the relationship between teacher enthusiasm, support for teacher autonomy, support for relationship with peers, and grit for preliminary high school students. This will be able to provide useful information for effective instruction and search for various teaching-learning methods in the physical education field. It was selected based on convenience sampling and judgmental sampling, focusing on those who participate in physical education classes for middle school students. Of the 200 respondents to the questionnaire, the study was conducted through 182 copies, excluding 18 questionnaires that were judged to be unreliable or responded collectively. When looking at the effects of physical education teachers' passion on autonomy support and relationship support, the hypothesis was adopted as it was found to have a statistically significant effect. Relationship support appeared to have a statistically significant effect on grit, so the hypothesis was adopted. However, support for autonomy was rejected as it did not appear to have a statistically significant effect on grit.

In this study, we analyzed the uses of external representations in material units of 7th grade science textbooks developed under the 7th National Curriculum on the basis of theories and research results on learning with multiple representations. The results revealed that the frequencies of microscopic external representations were higher than those of macroscopic and symbolic external representations. The external representations with drawing and/or writing were presented more frequently than those without drawing and/or writing. Furthermore, the external representations were rarely presented on the basis of the principles (e.g., personalization principle) and/or theories (e.g., dual coding theory, cognitive load theory, and social constructivism theory) for effective uses of the external representations in learning with multiple representations. Educational implications are discussed.

The purpose of this study was to develop and implement a wetland education program using ecotourism and investigate its effect on middle school students' environmental literacy. The wetland education program was developed by analyzing the 2015 revised curriculum and integrating content from science, social studies, ethics, technology, and home economics. The subjects of this study were 49 second-grade middle school students in Jeju City. The analysis revealed that the wetland education program using ecotourism improved environmental literacy in both the cognitive and psychomotor domains. In particular, the students' awareness of the 'causes of climate change' and 'responses to climate change' appeared to have increased. Although environmental literacy in the affective domain did not improve, there were positive effects in specific areas, such as attitudes toward pollution and proactive behavior. Based on the results of this study, follow-up research should further explore using ecotourism as an effective method to enhance wetland education.
