This endeavor is an attempt to explore the effect of flipped classroom strategy (FCS) on (a) academic achievement in the computer and information technology course and (b) students' attitudes towards this strategy. The sample of the study consisted of 64 students, divided into two groups: experimental and control groups. Two instruments were used to collect the data: a test and a questionnaire. The test was used to measure the students' achievement and the questionnaire to measure their attitudes towards the FCS. The results show statistically significant differences at the level of 0.05 in support of the experimental group at all Bloom's levels. Similarly, students' positive attitude towards the FCS was evident. Therefore, expanding this strategy in different courses is highly recommended because it positively impacts students' achievements. Organizing workshops and designing courses that encourage teachers to implement the strategy in the classroom and develop their technical skills are also recommended.

This study investigates the impact of flipped classroom strategy in developing students' achievement and acquisition of life skills. The study employed a quasi-experimental design where students were divided into two groups: an experimental (N=22) and a control (N=22). The randomly selected and assigned sample consisted of sixth-year elementary school students studying English as a basic course. The findings revealed statistically significant differences between the two group's means in both achievement and life skills tests in favor of the experimental group. Students of the experimental group who studied using the flipped classroom strategy outperformed the control group who studied in the standard way in achieving the English language and in the life situations test, where the effect size of the use of the strategy was large in both dependent variables. The study is concluded with some recommendations to facilitate the use of flipped classroom strategy for EFL teachers. This can be achieved by training teachers on using the strategy and providing technological resources at schools to implement the strategy efficiently.

This study examines diagrams of space organization and classroom activity zoning through Korean Childcare Accreditation Criteria, and compares space diagrams with childcare facilities in Daejeon, and looks at similarities and differences between them. Space diagram from accreditation criteria show the classroom, adjoining toilets, napping areas, and community areas for playing, reading, cooking, teaching and holding materials. Classroom zone diagrams show 8 activity zones for entering, washing and toilet, making art, playing, reading, studying science, resting, playing role and wooden block. Six case studies in Daejeon, Korea were surveyed and classified into big, medium and small size facilities by the number of children. The space organization of case studies are similar to the diagrams, except that outdoor playground and indoor playrooms were not large enough at the small and medium size facilities. Classroom activity zoning was very similar to the conceptions, excluding the playarea from classroom, integrating the rest areas for reading, subdividing art into music and art, science, and into math and science, roleplay into roleplay and wooden block. In conclusion childcare centers in Daejeon are designed to the concept diagram of the accreditation criteria, with some flexibility, exclusion, integration, and subdivision of space and activity zones. It has been requested as to make each criteria fit to the facility sizes-big, medium and small.

In this study, the perceptions of science classroom climate were investigated for 360 elementary and middle school students in mixed classes. The instrument used was an adapted version of the Student Perception Questionnaire (SPQ), which consists of five elements-Participatory Climate, Personalized Interaction, Student Assertiveness, Positive Teacher, and Negative Teacher. The results indicated that the gender differences in the perceptions of the Participatory Climate and the Positive Teacher were not significant for middle school students. However, the differences were found to be significant in the perceptions of the Negative Teacher, the Personalized Interaction and the Student Assertiveness, which measure the climate for the individual student. On the other hand, elementary male and female students did not significantly differ in the perceptions of science classroom climate except one item on the Participatory Climate. Educational implications are discussed.

Background and objective: This study aims to develop and apply programs in agriculture and life sciences for promoting divergent thinking in STEAM using classroom wall gardens. The process of the STEAM program such as presentation of the situation, creative design, and success experience is proposed to utilize STEAM education as a distinguished program. Methods: Four types of classroom wall gardens were used in this program, such as the 'plaster pot wall garden', 'attachable LED wall garden'. 'coffee pack wall garden', and 'hanging wall garden' for each classroom. For this purpose, official letters were sent to relevant institutions (elementary schools) specified by the research institute, and classes were conducted on the selected elementary school students. Results: A satisfaction survey and effect analysis were conducted on the students participating in the program. The program was designed to take a total of 11 hours, comprised of teaching plans including the topics, purpose of production, subject outlines, learning goals, and elements of STEAM subjects and stages. Conclusion: According to the survey on student satisfaction and understanding, it was found that students participating in the program have a high level of understanding and participation, as well as increased interest in science. Also, the program helped the students to connect with other subject areas. The level of student satisfaction was especially high in the upper grades. It is believed that the results of this research contribute to the development of STEAM education programs in agriculture and life sciences as well as other subject areas.

The microbial contamination levels of school classrooms were assessed as foodservice environments for elementary students. Two elementary schools located in Kyunggi-do were selected, and the total plate counts (TPC) and coliforms were measured from the classroom facilities, including the tables, chairs, floors, shelves, doors, as well as the hands of students, and the air of classrooms. The TPC of the classroom facilities were relatively low ranging from 2.30 to 3.79 log CFU/100 cm$^2$. The TPC counts from the hands of serving students and served students, were 6.39 and 5.33 log CFU, respectively, and the TPC counts of the foodservice utensils were <3.00 log CFU/ea before use and 4.77 CFU/ea after use. The air samples of 'empty classrooms during physical education', 'after physical education class', and 'during lunch' showed the contamination levels of 26 CFU/m$^3$,392 CFU/m$^3$, 364 CFU/m$^3$, respectively, suggesting that the microbial levels in the air varies greatly depending on the class activity before foodservice. When the TPCs of the air during lunch were measured from 18 classrooms, the levels ranged from 76 to >2228 CFU/m$^3$. Coliforms were not detected in the classroom facilities; however, air samples of the classrooms showed 1${\sim}$2 CFU/m$^3$. The above results show that classroom air and the hands of students, can have high levels of microbial contamination, which must to be controlled for safer school foodservice.

이 논문은 인체치수와 교구에 기초한 일반교실평면크기의 산정에 관한 연구이다. 초등학교의 교육과정은 1960년대 이래로 지금까지 7차에 걸쳐 변화되었으며, 그러한 교육과정의 변화는 초등학교 일반교실의 평면에 반영되어 왔다. 새로운 교육과정인 제7차교육과정은 학급 내에서 다양한 활동을 수용할 것을 요구하게 되었다. 또한 교육부는 1997년 9월 학교시설기준을 폐지하였고, 일반교실의 규모가 교육의 질에 영향을 미치는 것을 고려할 때, 초등학교 일반교실의 크기에도 변화가 필요하게 되었다. 일반적으로 알려진 바와 같이, 각 부위별 인체치수는 키, 나이, 몸무게와 밀접한 관계가 있다. 이 연구에서는 한국인의 각 인체부위 치수를 산정하는데 있어서 키, 나이, 몸무게를 독립변수로 한 회귀분석이 사용되었다. 그 다음 각 부위별 인체치수, 교구 및 책상배열에 따라 일반교실의 크기를 산정하였다.
