The purpose of this study is to examine improvements of after-school care policy for elementary school-age children based on children's rights in the community. After-school care is important to support children right of survive and protect, as well as the right to development and participation. To support integrated child rights through the policy, local government's duty is growing in the Covid-19 world. Therefore, the main policy of out-of-school care is analyzed from the perspective of children's rights. Current after-care policy focuses on the right of protection privileges. Providing a safe facility is important, but there is a lack of policy design to expand children's options to learn by various activity which can be utilized with community resources as care contents. The role of government to this is requested to supplement accountability, fairness, democracy and public interest more than over quantitative expansion of services. This study presented an alternative based on the universal elementary care providing happy after-school hours.

Purpose: This study aimed to determine the correlation between job performance difficulties and job satisfaction that novice health teachers experienced in a new school environment, and provide the basic data necessary for policy development. Methods: Data were collected from 196 novice health teachers without in-service training program for the qualification of 1st grade and with less than four years of work experience in Korea. The self-report questionnaire consisted of general characteristics, perception of difficulties in job performance, and job satisfaction. The data were analyzed using the x² test, t-test, ANOVA, and Pearson's correlation coefficient. Results: Novice health teachers had the most difficulty in health education during their job performance, whereas teachers without hospital clinical experience encountered difficulties in health management. Those with less than two years of teaching experience or no experience of being contract health teachers had higher job performance difficulties. The results revealed that the lack of experience in performance at a school site had a considerable influence on the difficulty in job performance. In terms of job satisfaction, novice health teachers had the highest satisfaction with status recognition and the lowest satisfaction with their tasks in charge. Additionally, as the difficulty in job performance increased, job satisfaction decreased. Conclusion: The study results indicated the need for training to provide novice health teachers with sufficient experience in job performance before being placed in a school. The provision of support to respond to difficulties in job performance will improve job satisfaction and contribute not only to the development of novice health teachers, but also to the improvement of the quality of school health.

This study aimed to examine the effects of the character education program applying mindfulness diary in 'H' girls' middle school, which is implemented as a practical character education at the school level while supplementing the limitations of existing character education programs. To achieve this, the pre- and post-design of a single treatment group in which data were collected over three time periods over two years for all 182 enrolled students was conducted. As a result of repeated measures of ANOVA to examine the significant mean change in the data, this program significantly improved the level of self-control, prosocial behavior, and gratitude of students. This was not only showing a significant improvement one year after the start of the program, but also showing a continuous significant improvement even one year later. Based on the above results, the implications and suggestions of this study were discussed.

In this article, a fairly extensive literature review was conducted to depict the current status of academic motivation and its developmental trend among Korean adolescents. The focal factors were perceived competence and autonomy which have been considered as major determinants of academic motivation. Theoretical frameworks adopted were self-efficacy theory, expectancy-value theory, and self-determination theory. Empirical studies conducted in Korean educational settings during the past decade were the target of the literature review. Results of the literature analysis revealed that, in general, there was a decreasing tendency in perceived competence from elementary to middle school which followed by a slight increase after entering high school. Similar trend revealed in the development of autonomous motivation, in that middle and high school students' intrinsic motivation levels were lower than that of the elementary groups. The amotivational tendency was increased as the grade level proceeded toward high school, which requires attention from educators. Discussion was followed in an attempt to provide plausible interpretations for this undesirable current status of Korean adolescents' academic motivation and to suggest implications for possible remedial actions both in pedagogical perspectives and students' well-being.

The purpose of this study is to examine the mediating effects of fandom activities on the path between depression and career-identity of adolescents. For the purpose, the study analyzes the longitudinal data of 941 adolescents from the 4th through 6th waves accumulated by the panel study of the Korea Children and Youth Panel Survey(KCYPS) of the Korean National Youth Policy Institute. For analytic methods, we use structural equation modeling, and the bootstrapping method. The results of the structural equation modeling analysis show that depression of adolescents has a direct negative influence on their career-identity. In addition, depression also has a direct positive association with on fandom activities influence. Lastly, the study results reveal that adolescents' fandom activities have a significant mediating effect on the relationship between depression and career-identity. In other words, depression itself has a negative effect on youth career identity, but increases the level of youth fandom activities, and the increased fandom activities can affect career identity positively. In conclusion, the study discusses practical and political implications regarding the positive function of youth fandom activities for their developmental outcomes.

The purpose of this study was to construct an issue-centered discussion instructional model for Home Economics and to determine its effect on middle school students' critical thinking. The research questions were posed as below. 1) The object and content of home economics in the 7th national middle school curricula are analyzed to sort out possible issues. 2) An issue-centered discussion instructional model is constructed to be applicable to middle school home economics class. and a lesson plan is prepared. 3) The effect of the issue-centered discussion instructional model developed in this study on student critical thinking faculty is examined. The findings of this study were as follows : First. seven criteria were selected to determine what types of issues were applicable to home economics lesson. Based on the selected criteria. 41 themes of issues were extracted from the 7th middle school textbooks. and their content validity was verified. Second, an issue-centered discussion instructional model was designed to deal with four themes in eight sessions in the procedure of problem raising, confirming, term defining. tentative alternative selecting, data gathering. discussing/critical approaching. and selecting/concluding. Third, two different third-year classes of K middle school in the city of Busan that consisted of 75 students were respectively selected as an experimental group and a control group, and the experiment was conducted in eight sessions for five weeks to see whether the teaching plan brought any changes to the critical mind of the students. The experimental group exposed to the issue-centered discussion lesson made a significant progress in critical thinking faculty(P＜.05). In particular. that instruction gave a favorable impact on demonstration evaluating(P＜.05). one of the critical thinking subfactors. When the students were asked to assess the issue-centered discussion lesson. most of them viewed it favorably. In the future, more research efforts should be dedicated to enhancing the practical applicability of issue-centered discussion instruction in home economics education. developing good evaluation tools about critical thinking faculty and finding out how discussion instruction could be conducted more efficiently.

This study analyzed the frequency and level of scientific practices presented in secondary science textbooks. A total of 1,378 student activities presented in 14 middle school science textbooks and 5 high school integrated science textbooks were analyzed, using the definition and level of scientific practice suggested in the NGSS. Findings show that most student activities focus on three practices. Compared to the textbooks for the previous science curriculum, the practice of 'obtaining, evaluating, and communicating information' was more emphasized, reflecting societal changes due to ICT development. However, the practice of 'asking a question', which can be an important element of student-led science learning, was still rarely found in textbooks, and 'developing and using models', 'using math and computational thinking' and 'arguing based on evidence' were not addressed much. The practices were mostly elementary school level except for the practice of 'constructing explanations'. Such repeated exposures to a few and low level of practices mean that many future citizens would be led to a naïve understanding of science. The findings imply that it is necessary to emphasize various practices tailored to the level of students. In the upcoming revision of the science curriculum, it is necessary to provide the definition of practices that are not currently specified and the expected level of each practice so that the curriculum can provide sufficient guidance for textbook writing. These efforts should be supported by benchmarking of overseas science curriculum and research that explore students' ability and teachers' understanding of scientific practices.
