이 연구는 창의적 교실 환경이 자기 조절학습과 학습 효능감을 매개로 학업성취도에 미치는 영향을 확인하기 위한 목적에서 수행되었다. 이를 위해 한국아동패널의 14차 조사의 원시 자료를 활용하였고, 주요 변인에 관하여 누락 응답이 없는 593개 자료를 연구 대상으로 선정하여 SPSS 26.0 및 AMOS 26.0 프로그램을 활용하여 구조 방정식 모형으로 검증하 였다. 분석 결과, 중학생의 창의적 교실 환경 인식, 자기 조절학습, 학습 효능감, 학업성취도 간에는 모두 정적으로 유의미한 상관관계가 있었다. 또 창의적 교실 환경 인식과 학업성취도의 관계를 자기 조절학습과 학습 효능감이 유의하게 매개하는 것으로 나타났다. 즉, 중학생이 수업 시 교 실 환경을 더 창의적이라 인식할수록 자기 조절학습이 촉진되며 이는 학 습 효능감을 증진함으로써 결과적으로 학업성취도가 높아지도록 만들 수 있음이 확인되었다. 이를 토대로 한국의 공교육이 중학생의 학업성취도 증진을 위해 조성해야 할 교실 환경의 중요성 및 나아가야 할 방향에 대 해 제언하였다.

In this paper, a survey on students’ perceptions of air pollution, particulate matter (PM) and indoor air quality (IAQ) in school classrooms was analyzed. A total of 174 students participated in the survey, where 127 and 47 participants were elementary school students and middle school students, respectively. The elementary school was located in a rural area of Korea, whereas the middle school was located in an urban area. The questionnaire of the survey was mainly composed of three parts: (1) students’ perceptions of air pollution, (2) students’ perceptions of IAQ in the classroom, and (3) students’ perceptions of how to improve IAQ in the classroom. Based on our study, the responses of the students for the given questionnaire showed an opposite tendency. The students in the rural area tended to have positive perceptions regarding IAQ in the classroom as well as air pollution, whereas the students in the urban area revealed negative perceptions for the same items. Our survey results can be used by school officials in order to maintain and improve IAQ in school classrooms based on the perceptions of the students.

This paper explores initiators of humor and the differing characteristics of humor these initiators use in elementary-level English classrooms in Korea. Forty-nine videotaped ordinary classes and interviews with four teachers were investigated. Teachers tended to make learners the subjects of humor, with this type of humor attracting students to participate in learning. Furthermore, teachers encouraged learners to pay more attention to the form of English language features by humorously revealing mispronunciations or expressions that learners could easily make mistakes with. Additionally, among learners, the primary users of humor were middle- to lower-level students. Teachers needed to build a safe environment for English underachievers who unintentionally made humorous mistakes so that they would not be mocked. Also, certain boys intentionally tried humor to get attention. It is noteworthy that teachers and learners jointly constructed humor by supporting each other. This conjoint humor reaffirms the importance of teachers’ reactions and attitudes towards pupils. By listening attentively and accepting learners’ remarks, teachers could make humorous, meaningful interactions. The current paper projects some pedagogical implications concerning how to use or deal with humor for foreign language teachers.

In this study, the effect of improving indoor air quality according to the installation of plants was evaluated in classrooms where students spend much time. The purpose was to prepare sustainable and eco-friendly measures to improve the indoor air quality of school classrooms. A middle school in Bucheon was selected as an experiment subject, and IAQ monitoring equipment based on IoT was installed to monitor indoor air quality. After measuring the basic background concentration, plants and air purifiers were installed and the effects of improving indoor air quality using plants and air purifiers were evaluated based on the collected big data. As a result of evaluating the effects of indoor air quality improvement on the installation of plants and air purifiers, the reduction rates of PM10 and PM2.5 in descending order were plant- and air purifier- installed classes, air purifier-installed classes, and plant-installed classes. CO2 levels were reduced in the classrooms with only plants, and increased in two classrooms with air purifiers. The increase in CO2 concentration in the classrooms with plants and air purifiers was lower than in those with only air purifiers.

In this paper, we conducted a survey to reveal the general perception of parents toward outdoor air quality, particulate matter (PM), and indoor air quality (IAQ) at schools where their children attend. A total of 1,030 parents participated in this survey, where the age of their children ranged between 7 years to over 19 years of age. Each participant was either a member of a non-governmental organization (NGO) with a keen interest in air quality or an ordinary public panel member with less interest. The result of the survey indicated that the participants had a negative perception of air quality, and parents believed that the outdoor and indoor air is extremely polluted. The participants pointed out that they believe that the main reason for the pollution is due to particulate matter (PM) and school classrooms are the location where their children are exposed to PM the most. Based on our study, the majority of the participants prefer a mechanical ventilation system to reduce indoor air pollutants in schools. Our study should be referred to by school officials in order to maintain IAQ and as a way of addressing the concerns of parents who want to protect their children’s health.

This paper explores the types of verbal humor that occur during interactions between teachers and learners in elementary-level English classes in Korea. Eighty-three videotaped ordinary English classes and interviews with seven teachers were analyzed. Spontaneous verbal humor was generally expressed in a mixture of English and Korean due to teachers’ and learners’ limited English proficiency. Wordplay was most prevalent, as learners often found Korean words that sounded similar to novel English terms. Teasing appeared quite frequently as well, with learners and teachers engaging in it to distract and gather attention, respectively. Senior students told the most jokes in order to save face. Narratives were found only in female teachers’ classes, as they shared personal anecdotes while their male counterparts did not. Meanwhile, hyperbole and self-deprecation were less likely to occur than other types of humor. Ultimately, humor is reaffirmed as a positive learning opportunity. Some pedagogical implications of these findings are suggested for English teachers.

This study is about meta-language used for teaching the Korean language in Serbia, where it is not a native language. This study examined meta-language for teaching preferred by Korean language learners of Serbia and explored efficient methods of meta-language use for teaching. First, meta-language and meta-language for teaching were discussed, and meta-language for Korean language teaching was defined. After setting up the research question and hypothesis, a survey was conducted on Korean language learners at the University of Niš in Serbia to determine their preferred meta-language for teaching. According to the survey, many learners wanted to take classes in ‘Korean-Serbian languages.’ Beginner and intermediate learners of vocabulary, grammar, and conversation preferred ‘Korean-Serbian’ meta-language for teaching, and advanced learners preferred ‘Korean’ meta-language for teaching. Based on such grounds and existing theories, this paper proposed a usage model of meta-language for teaching in beginner, intermediate, and advanced Korean language classes in Serbia and presented the necessity for fostering professional Korean language instructors overseas.

This study was conducted as a part of the research for the “Development of Big Data Analysis Techniques and AI-based Integrated Support System for Energy-Environment Management.” We collected research results on characterization of distribution of fine dust and re-analyzed using meta-analysis techniques to build “big data” with high potential for school environments. The results of prior studies on the characteristics of fine dust concentration distribution in a school environment conducted in Korea were collected and re-analyzed the results using the metaanalysis technique. In this manner, the variables that could be used to derive the independent variables needed to produce the e-coding book prior to the big data collection, were first derived. The possibility of using the data as independent variables was then evaluated. In this study, three variables: “elementary school vs. middle school vs. high school,” “general classroom vs. special classroom,” and “new classroom vs. old classroom” were evaluated for their application as major classification variables with priority. The necessity of being derived as a major classification variable was examined by testing the difference in fine dust concentration distribution in the school environment by each variable case. Results showed that “elementary school vs. middle school vs high school” and “general classroom vs. special classroom” could be used as independent variables, while “new classroom vs. old classroom” was less likely to be used as an independent variable.
