This study aims to review the characteristics of specialized classrooms for governmental secondary schools in the Japanese Colonial Era by analyzing architectural drawings collected by National Archives of Korea. The results of this study are summarized as follows 1) Under the influence of Japanese science promotion of that time, specialized classrooms for science were considered as one of essential facilities. Typically exclusive specialized classrooms were assigned to two major science subjects : physics-chemistry and biology. 2) To science specialized classrooms, ancillary rooms for preparation, experiment equipment and specimen were attached and science lecture room with stepped floor was planned additionally only for the lecture on theories and the demonstration of experiment. 3) Specialized classrooms for science were zoned independently of other facilities because of the special equipments and safety. 4) Art rooms were common to both boys' and girls' schools but concerning music rooms, girls' schools had special concerns, whereas boys' schools did not. 5) Specialized classrooms for homemaking subject of girls' school were as much important as those for science subjects of boys' school. 6) Some early-established Korean boys' schools had handicraft rooms which were the symbol of vocational education-oriented, unequal policy on Koreans. Though not general cases, specialized classrooms for geography-history were planned for Japanese boys' school. Restricted to governmental secondary schools but considering the uncommon state of specialized classrooms of that time, these characteristics show conditions of early time when special classrooms were introduced into Korea.

This study aims to investigate the awareness and policy demands of after school care classes of mothers with elementary school children. The participants of study were 25 mothers with elementary school children in Seoul, Gyeonggi, Incheon, Gangwon. Data collection was conducted from June 23, 2017 to July 18, 2017 by focus group interview. Through the data analysis, the results of the study were analyzed as 'the reality of the after school care class that the mother sees' and 'the policy demands of the mother's after school care class'. 'The reality of the after school care class that the mother sees' is 'the overall level of after school care class is low', 'the probability of selecting the same as a lottery', 'the quality of education that varies depending on the level of the teacher', 'for the child attending the care class negative awareness'. 'Mother's policy demands for after school care classes' are presented as 'positioning as a substitute for thinking and caring', 'improvement of separation between parents' expectations', 'expansion of care recipients', 'request for resilient management'. As the conclusion of this study, first, after school care classes need to focus on the care function. Second, it is necessary to operate after school care classes by level. Third, the realistic needs of mothers should be reflected so that after school care classes can be positioned as alternatives to private education.

In this study, we will analyze the classroom space of elementary schools that have implemented the Seoul Metropolitan Government's 'Dream Classroom' project and identify satisfaction and needs in terms of users. Primary school was selected and the composition and color of space was investigated by the present ministerial inspection. The survey was conducted on homeroom teachers and analyzed as SPSS/WIN Statistical Programme 22.0. The satisfaction level of space elements was verified by the technical statistical analysis, the general classroom and the 'classroom with dreams' difference in response t-test, the need for planning elements (criticality), and the difference in satisfaction with one way ANOVA. The space had the most separate, primary-colored classrooms. They preferred emotional factors and bright and light atmosphere for the lower grades, and the soft and soft atmosphere for the middle and high school students. The school preferred communication space with the community, proper play and relaxation space for the complex type of classroom. This will help set the direction for elementary school classroom space planning during the Fourth Industrial Revolution.

본 연구의 목적은 2011년 3월 한국 학교에서의 체벌이 법적으로 금지된 이후 훈육방법과 교실경영의 변화 방향을 탐색하는 것이다. 연구의 목적을 달성하기 위하여, 첫째, 한국과 해외 국가의 체벌에 대한 경향을 살펴보았다. 체벌은 한국 사회, 가정, 그리고 교육기관에서 오랜 역사를 가진 전통적인 훈육 방식으로 특히 군사부일체, 스승의 그림자는 밟지 않는다, 사랑의 매 등과 같이 스승의 권위를 근거로 행하여져 왔다. 2012년 현재 세계 국가들 중에서 59%가 체벌을 금지하고 있으며, 특히 OECD 34개국 중에서는 29개국이 체벌 금지, 한국을 포함한 4개국이 부분적 금지 등으로 대부분의 국가들이 체벌을 금지하고 있다. 둘째, 한국과 해외 국가의 교실경영 방법을 비교해 보았다. 한국에서는 문제행동의 지도방법이 벌점부여 등과 같이 단순하고 소극적이며, 교육적 효과에 대한 검증 부족, 문제행동 지도방법에 대한 사회적 합의부족 등과 같은 한계가 있었다. 해외 국가에서는 문제행동의 체계적 유형화, 문제행동의 원인 연구, 문제행동 지도방법 체계화 및 위계화, 문제행동의 예방과 지도방법의 효과 연구 등이 활발하였다. 따라서 체벌 금지 이후 한국 교실경영에 대한 시사점으로, 문제행동 지도방법에 대한 심도있는 논의, 문제행동 예방 및 지도방법에 대한 효과 연구, 교원양성 및 현직 교육에 문제행동 지도방법 교육, 학생 문제행동 지도에 대한 사회적 합의 등을 제안하였다.

This study is to make strides toward an enriched understanding of changing a prevailing teacher-centered mathematics classroom culture to a student-centered culture by analyzing six reform-oriented classrooms of three elementary school teachers throughout a year This study provided a detailed description of important classroom episodes to explore how the participants in each class established a reform-oriented mathematics microculture. Despite the exemplary form of student-centered instruction, the content and qualities of the teaching practices are somewhat different in the extent to which students' ideas become the center of mathematical discourse and activity. Given the similarities in terms of general social norms and the differences in terms of socio-mathematical norms and mathematical practice, this study addresses some crucial issues on understanding the culture of elementary mathematics classroom in transition.

This study was to examine the differences of Korean and Chinese high school students on classroom goal structure(i.e., mastery, performance-approach, and performance-avoidance), help-seeking behavior(i.e., help-seeking, and help-seeking avoidance), and school engagement(i.e., behavioral, cognitive, and emotional), and to identify the mediating role of help-seeking behavior in the links between classroom goal structure and school engagement. The final samples consisted of 290 Korean and 294 Chinese students in high school. Results were as followed. Firstly, Chinese students had a higher classroom mastery goal structure, classroom performance-avoidance goal structure, help-seeking and emotional engagement than Korean students, whereas Korean students had a higher behavioral engagement than Chinese students. Secondly, for Korean students, help-seeking and help-seeking avoidance mediated between classroom mastery goal structure and school engagement. Moreover, for Korean students, help-seeking avoidance mediated between classroom performance-avoidance goal structure and school engagement. While, for Chinese students, help-seeking and help-seeking avoidance mediated between classroom performance-avoidance goal structure and school engagement. Also, for Chinese students, help-seeking avoidance mediated between classroom mastery goal structure and school engagement. Therefore, help-seeking should be promoted in order to improve students' school engagement, and classroom mastery goal structure need to be created in order to encourage students' help-seeking.
