Over four years (2020–2023), 305 traps were strategically placed across South Korea to collect data on Vespidae species. Our findings showed that Vespula flaviceps, Vespa crabro, and Vespula koreensis were the most frequently encountered species. Vespa velutina was also widespread, suggesting its successful integration into local ecosystems. The ARL analysis, using the “apriori” algorithm, identified significant co-occurrence patterns and potential interactions. The rules generated indicated both competitive and coexistent relationships with varying levels of association strength across different regions. Clustering analyses, including hierarchical and k-means clustering, grouped species based on their occurrence similarities. The distinct clusters formed in the analysis highlighted the unique ecological roles and interactions of V. velutina and other Vespidae species in South Korean ecosystems.

This study aims to investigate the interaction patterns between the teacher and students or among students themselves in a Korean elementary English classroom by analysing classroom talk and by focusing on the types of the teacher’s questions and feedback as well as the use of L1 and L2. This analysis is used to determine the influence of such interaction on the students’ communicative skills in English. A female teacher in Gyeonggi province and a 6th-grade class participated in the data collection. This study included data from video or audio recordings, interviews, field notes, self-assessments, and portfolios. The transcribed data were analysed using Tsui’s (1994) framework and Verplaetse’s (1995, 2000) coding system. The results of this analysis indicated that the interaction patterns varied between participants into three groups: teacher-initiated talk (e.g., T-S talk) vs students-initiated talk (e.g., S-T talk & S-S talk). At the beginning stage of lesson, the teacher-initiated talk made up the majority of talk in English, and facilitated the students’ involvement in classroom learning including their language use. In the S-S talk, the students were involved in interaction which occurred naturally without the teacher’s control.

The purpose of this research is to explore the interaction patterns in an English (L2)-mediated Mandarin Chinese (L3) class (native-taught) for young monolingual Korean (L1) learners. Twenty-nine class videos were collected and transcribed into 152 pages of Chinese, English, and Korean for this analysis. The interaction patterns in the English-mediated Chinese classes were analyzed using the IRF framework of Sinclair and Coulthard (1975) and Tsui (1994). The results and discussions were integrated into four main patterns to interpret the English-mediated Chinese classes: 1) the native Chinese teacher’s needs for class assistance, 2) the students’ enthusiastic but inadequate use of English, 3) the students’ voluntary Korean scaffolding, and 4) the students’ class participation needs. On the one hand, this research has provided the students’ response to the teacher’s use of Chinese and English (in a foreign language-only environment), which is intended for a better understanding of a classroom with a trilingual teacher and monolingual students. On the other hand, the research has implications for understanding use of an L2 to facilitate an L3 classroom, particularly in the situation of using two foreign languages in one classroom.

탐구는 과학교육의 본질을 설명해주는 결정적인 특징이다. 최근에는 스스로 문제를 제기하여 탐구하고 그것을 의사 소통하는 능력을 포함한 논증이 강조되고 있는데, 학교 탐구학습 맥락에서는 자율적이고 활발한 상호작용의 측면에서 그 한계가 지적되고 있다. 그래서 대안으로 비형식 맥락에서의 탐구학습이 제안되고 있으며, 이에 본 연구는 국립과천과학관 내 자연사관을 자유 관람하는 중학생 소집단의 대화적 탐구에서 나타나는 상호작용 유형을 밝히고자 하였다. 이를 위해 중학생 13그룹의 탐구적 대화 42사례를 대상으로 탐구요소 및 상호작용 유형을 분석하였다. 탐구요소는 문제제기, 자료수집, 설명의 세 가지로 구분하였고, 상호작용은 대화의 흐름을 화살표로 도식화하여 나타내었다. 문제제기로부터 탐구가 시작된다고 보았으며, 문제제기 이후 후속적인 반응에 따라 유형이 구분되었는데, 총 7가지 유형이 발견되었다. 그 유형은 문제제기 공유, 문제제기-단순응답, 문제제기-단순설명, 문제제기-단순설명-(자료수집)-자료기반 설명, 문제제기-자료수집-자료기반 설명의 5가지로 크게 나누어지고, 가장 많은 빈도를 보인 유형 2는 다시 소극 회피적 응답, 부정확한 응답, 패턴의 반복으로 세분화되었다. 본 연구는 비형식 탐구학습에서 학교 탐구학습과 차별화되는 상호작용 패턴을 파악하였다는 점에서 기존 연구들과 차별성을 가지며, 비형식 탐구학습에서 상호작용 유형을 기술하고 있다는 점에서 비형식 탐구학습 연구를 위한 기초를 제공하였다는 의의를 가진다.

The purpose of this study is to analyze teachers' questioning patterns in EFL classes, and propose a new set of classification based on the interaction flow that a question initiates and the teachers' intention of questions in language classroom. Data were collected from five advanced EFL classes. Six categories of teacher questions were observed and two types of interactions following the initial questions were found. The interactions were usually opened by the teacher, which confirmed the general conception, and the types of interactions were mostly chosen by the teacher's preference and the activity the class was doing.
