In this paper, in order to prepare a classroom model that can effectively operate SW education, this study explored cases of creative educational space construction overseas and conducted a demand survey on elementary and middle school teachers. As a result, in overseas cases, classrooms were constructed in various forms, and furniture in the classrooms were produced in various shapes and sizes, and the cases using advanced equipment were explored. As a result of the survey on the education site, it was found that the most desired installation is a fluid type that can restructure the space by freely moving the facilities according to the teaching method. The results of the analysis are expected to be of great help in rebuilding computer labs or building infrastructure for future SW training.

This study aimed to investigate how two eighth-grade mathematics teachers' pedagogical content knowledge is manifested in their classroom instruction. A case study was conducted for the study. The results revealed similarities and differences in the teachers' knowledge manifested in their mathematics classrooms and that the two teachers had slightly different structures of pedagogical content knowledge. One teacher is more dependent on his knowledge of mathematics and knowledge of students' understanding and the other teacher on her knowledge of instructional process and, to a lesser extent, knowledge of mathematics.

Background: Adolescents are relatively more sensitive than adults to exposure to indoor pollutants. The indoor air quality in classrooms where students spend time together must therefore be managed at a safe level because it can affect the health of students. Objectives: In this study, three types of green-wall models were applied to classrooms where students spend a long time in a limited space, and the resulting effects on reducing PM were evaluated. Methods: In the middle school classrooms which were selected as the experimental subjects, IoT-based indoor air quality monitoring equipment was installed for real-time monitoring. Three types of plant models (passive, active, and active+light) were installed in each classroom to evaluate the effects on improving indoor air quality. Results: The concentration of PM in the classroom is influenced by outdoor air quality, but repeated increases and decreases in concentration were observed due to the influence of students' activities. There was a PM reduction effect by applying the green-wall model. There was a difference in PM reduction efficiency depending on the type of green-wall model, and the reduction efficiency of the active model was higher than the passive model. Conclusions: The active green-wall model can be used as an efficient method of improving indoor air quality. Additionally, more research is needed to increase the efficiency of improving indoor air quality by setting conditions that can stimulate the growth of each type of plant.

Assessment of science laboratory environment was conducted with 539 students at middle and high school. Science Laboratory Environment Inventory(SLEI) was used as an instrument. The major findings of this study are as follows. 1. Mean scores obtained on each scale in the actual and preferred version of SLEI were relatively low, particularly on the scale of open-endedness, integration, and material environment. 2. Mean scores obtained on each scale in the actual version were lower than those in the preferred version. Score differences between actual version and preferred one were found to be significant statistically. 3. Boys and high school students perceived their laboratory environment with more open-endedness and less rule clarity than girls and middle school students respectively. 4. Girls preferred student cohesiveness at their laboratory more than boys. Highschool students wanted open-ended environment more than middleschool students. 5. Each scale of SLEI showed significant correlation with the scores of attitudes toward science. Particularly open-endedness was found to account for a significant contribution to the affective outcomes.

This study has researched the indoor air Pollution in the school classrooms. It focused on the school classrooms in which the students take part in many loaming activities for a long time, not focused on the offices or underground facilities that have occupied the interest so far. First, I investigated the origination sources of indoor air pollution which influences on our health, and researched the data on the consequences of it on the human body. Second, I measured the indoor air Pollution level of the classrooms in which the students take part in activities. I selected CO, $CO_2,{\;}SO_2,{\;}NO_2$and $PM_{10}$ as the research items. Each two schools were chosen in the elementary schools, middle schools and high schools as the ones for measurement. And I distinguished the boys' schools from the girls' schools in the middle and high schools. CO, $SO_2{\;}and{\;}NO_2$were comparatively low comparing with the recommendation of the Ministry of Environment. But, $CO_2{\;}and{\;}PM_{10}$ exceeded the standard concentration in most schools and there was a difference between boys'classrooms and girls'classrooms about them. Also, it was different by the number of members a classrooms. Third, I made a questionnaire on the on the indoor air pollution. The questionnaire showed that many students feel the indoor air pollution directly and they are under the influence of it.

Background: The indoor air quality of classrooms, in which the capacity per unit area is high and students spend time together, must be managed for safety and comfort. It is necessary to develop an eco-friendly indoor air quality reduction method rather than biased management that relies solely on air purifiers. Objectives: In this study, plants and air purifiers were installed in middle school classrooms to evaluate the indoor PM_2.5 reduction. Methods: Four middle school classrooms were selected as test beds. Air quality was monitored in real-time every one minute using IoT equipment installed in the classrooms, corridors, and rooftops. After measuring the background concentration, plants and air purifiers were installed in the classroom and the PM_2.5 reduction effect was analyzed through continuous monitoring. Results: After installing the plants and air purifiers, the average PM_2.5 concentration was 33.7 ㎍/m³ in the classrooms without plants and air purifiers, 25.6 ㎍/m³ in classrooms with plants only, and 21.7 ㎍/m³ in classrooms with air purifiers only. In the classroom where plants and air purifiers were installed together, it was 20.0 ㎍/m³. The reduction rates before and after installation were 4.5% for classrooms with plants only, 16.5% for classrooms with air purifiers only, and 27.6% for classrooms with both plants and air purifiers. The I/O ratio, which compares the concentration of PM_2.5 in classrooms with corridors and outside air, also showed the lowest in the order of plants and air purifiers, air purifiers, and plant-only classrooms. Conclusions: The PM_2.5 reduction effect of using plants was confirmed, and it is expected to be used as basic data for the development of environmentally-friendly indoor air quality improvement methods.

This study intended to grasp the results of performance of school health policy and to provide information for the future policy performance in Korea. As the objects of the study we chose the secondary school(142 middle schools, 111 high schools) in Pusan, 1993. The contents of the study were about school health service and school health education. For the study we collected datum and took statistics through the existing theses, books, various statistics, and interviews with the persons concerned. Therefore the method of the study was basically emperical and demonstrative. The results of the study can be presented as follows : 1. the results of performance of health service proved to be 5.40% for vaccination against hepatitis B, 5.26% for typhoid fever, 6.65% for EH fever, and 9.84% for influenza in middle schools, In high schools' 5.76% for vaccination against hepatitis B, 0.03% for typhoid fever, 0.25 for EH fever, and 0.86% for influenza. 2. The results of policy performance of health education were found out 64.08% in middle schools, and 17.12% in high schools. 3. The factors which affected the results of performance of health service turned out 1) the improper standard of policy performace that applicants should pay their own expenses. 2) the lack of performer's will to carry out the policy owing to the improper standard. 3) the shortage of interorganizational enforcement activities and communications which influence the will of performance. 4. The affecting factors to the will of performance of health education proved to be 1) the improper standard that nurse-teachers can teach students in the classroom in case of need. 2) the lack of nurse-teachers due to the above inappropriate standard. 3) the lack of enforcement activities of supervising organs which employ and direct nurse-teachers. 4) the lack of activities of organs which should communicate one another and allot nurse-teachers of public schools without fail.

This study examined the adequacy of a school classroom's occupant load density standard to cope with the issues associated with the decreasing number of students and regional variations. Therefore, this study analyzed the occupant load density standards of kindergarten, elementary school, middle school, high school, and universities using the data open to the public by the Ministry of Education. The results revealed a high variance in the occupant load density according to the school type. The median values were 1.49, 3.45, 2.64, 2.45, and $3.41m^2/person$ for kindergarten, elementary school, middle school, high school, and universities, respectively. Although the occupant load density was higher than the current standard ($1.9m^2/person$), except for kindergarten, the present standard did not need to be improved immediately, considering the purpose of calculating the maximum occupancy. On the other hand, if improvements are made in line with other enhancements of a national education policy, it will be possible to mitigate the measure to $2.5m^2/person$ based on the survey results.
