This study is to explore and analyze three current English teachers’ thoughts and attitudes on their TEE practices in elementary English classroom settings. Adopting a qualitative approach, data were collected through interviews, teachers’ journals, and informal communications from the three elementary school English teachers. The analysis of data revealed three main themes: 1) thoughts on effective TEE classes, 2) factors affecting TEE classes, 3) the difficulties of conducting TEE classes. The participants presented their views on effective TEE classes. They also expressed their opinion on the timing and usage of TEE. The teachers said TEE classes are influenced by teachers’ English communication ability and willingness to use English as the instructional language, students’ English proficiency and the class atmosphere. Finally, the participants said that TEE classes were difficult due to the same factors influencing TEE class effectiveness. This study has implications for the direction of TEE implementation in elementary education.

Modified dapped end, precast prestressed double-tee slabs were considered in this research. It can facilitate insertion of service ducts at the dapped ends. The total depth of the floor slab may be reduced. In addition, the underside of the double-tee slab showed simpler appearance. Static three-point shear loading test was performed on full-scale specimens. And three modified single-tee slabs were analyzed by strut-tie model method. The specimen failed during the test in the same location as predicted by the strut-tie analytical model. The analysis of experimental results in comparison to the analysis results revealed that the experimental failure loads manifested 108% of analytical failure loads on the average.

This paper investigates whether a secondary teacher trainee improved pair/group work management skills in a short-term teacher training program focusing on the development of TEE-related skills. One female teacher trainee, students, and a teacher trainer participated in the study. The participant’s teaching performance, conference on her teaching performance, lesson plans, and the teacher trainer’s feedback on the teaching performances were collected. The data on teaching performance and conferencing were transcribed and analyzed in terms of a moving-in phase, a monitoring phase, and a moving-out phase. The participant showed improvement in changing seating arrangement, selecting students in modeling, increasing various kinds of comprehension check up questions, changing her voice during monitoring, and drawing students’ attention and signaling a new phase of lesson to the students in a moving-out of the activity. This study suggests how to improve management skills in pair/group work in TEE classes.

The present study aims at investigating problems with a TEE class in terms of classroom activities and code-switching. One middle school teacher and her students participated in the study. The teacher taught a writing class in TEE context. She taught more than half of the class in English. Her students experienced different interactional patterns in four different activities. However, most of the students could not participate both in pair work and group work without her teacher’s help. That was because the teacher had problems with giving instructions: (1) her instructions about the activities were not clear enough; (2) she did not provide any modelling for the activities; and (3) she did not check any clarifications for the activities. Also, the ratio of the teacher’s utterance to students’ was too high: 96% in English and 89.5% in Korean. In addition, she did not use any pause in code-switching from English to Korean, deprived of checking whether her students understood the target language input given in English. Directions for further research and pedagogical implications will be discussed.

The purpose of this study is to gauge the opinions of parents and teachers of English for the primary and secondary schools. It seeks to discover the implications for English education and provide referential data necessary to run a better English policy in school. A survey was conducted on a total of 3,294 particpants including 2,040 parents of public schools and 1,254 English teachers in primary and secondary schools. The questionnaire consists of 12 questions about the policies of TEE (Teaching English in English) and the NEAT (National English Ability Test). We used the SPSS 20.0 software to perform chi-square and t-tests. The results showed that teachers and parents were in agreement about the necessity of both TEE and the NEAT. In particular, the majority of parents thought that teaching English in English is important, and that the NEAT should be used for practical English improvement.

A new in-service teaching certificate system, the TEE Certificate system, was launched for Korean teachers of English with the aim of encouraging them to use English in their daily teaching practice. This study attempts to investigate key issues regarding the current development of the TEE Certificate system and addresses the implications for a successful TEE policy in Korea. It employs document analysis produced by the Ministry of Education, Science and Teclmology and to key Regional Offices of Education and semi-structured interviews with 15 supervisors, 11 teachers and 2 TEE Certificate examiners. The research findings suggest that there is a gap regarding the aims of the TEE Certificate system among stakeholders, leading to the different attitudes toward it. Those who have positive perceptions of the system see it as a tool for encouraging Korean teachers of English to develop their English language teaching competence. On the other hand, those who have negative attitudes see the negative aspects such as another type of burden on teachers and even the possibility of a form of lay-off. The new strategies of how to use the system are required to make it play a proper role in terms of the provision of an English-fi'iendly learning environment and supporting teachers' professional development.

In this paper, we present the results of experimental investigation pertaining to the structural behavior of Tee joint connection composed of pultruded I-shape FRP members. In this study, we focus on the evaluation of load carrying capacity of Tee joint which appeared frequently to fabricate framed structure composed of pultruded FRP members. Through the experimental investigation moment-rotation relationship is found and the result is used to estimate the rotaion stiffness.

This research is trying to figure out the factors that make effects on the body movement and batting speed of the 6 middle school baseball players and the 6 common students using the equipment of the video analysis and ground reaction force. By doing so,

선박은 상자형태 구조로 구성되어 있으며 선박의 선 수미, 선저만곡부, 갑판 등에 주로 사용하고 있다. 이런 구조는 박판구조이며 1차 지지부재로 사용된다. 평판구조와 비교하였을 때 상이한 거동을 보이며 일반적으로 압축하중을 받을 경우 곡률변화에 따라 다른 좌굴 및 최종 강도 경향을 나타냈다. 따라서 본 논문에서는 압축하중을 받고 있는 보강곡판인 1/2+1+1/2 bay 모델에 대하여 비선형유한요소해석을 수행하였으며 매개변수 영향은 곡률변화뿐만 아니라 세장비, 웨브높이/두께 등을 고려하여 해석모델에 대한 붕괴모드에 대해 검토하였다.

원자력발전소에 지진격리장치를 설치하면 지진에 의한 하중을 지진격리장치가 담당하면서 설치 전보다 큰 변위가 발생하게 될 것으로 예상되며, 변위증가에 따라 일부 설비의 지진리스크가 증가될 가능성이 있다. 특히 지진격리된 구조물과 일반 구조물을 연결하는 설비인 배관 시스템의 경우 지진리스크가 크게 증가될 것으로 예상된다. 본 연구에서는 원자력발전소 배관 시스템의 취약부위인 강재 배관 Tee의 한계상태를 누수로 정의하고 면내반복가력시험을 수행하였다. 강재 배관 Tee의 모멘트와 변형각은 기존의 센서를 이용한 계측이 어려우므로 이미지 신호를 이용하여 측정하였다. 본 연구에서는 3인치 강재 배관 Tee의 모멘트와 변형각의 관계를 이용한 누수 선도 및 저주기 피로 곡선들을 제시하였다.

본 연구는 PC 부재인 와플형상을 갖는 슬래브와 더블티형 슬래브에 대하여 보행 및 발뒤꿈치 가진등의 수직진동 하중을 대한 실험과 해석을 수행하여, 각각의 사용성을 비교 검토하였다. 수직진동하중에 대한 실험은 와플형 및 더블티형 슬래브가 모두 시공된 하남시에 위치한 상업시설을 대상으로 수행하였다. 실험결과에 대한 사용성 검토는 국제표준화기구의 ISO 2631-2와 일본건축학회의 건축물의 진동에 관한 거주성능 평가지침·동해설에서 제시한 기준을 바탕으로 평가하였다. 실험결과, 와플형 및 더블티형 슬래브 모두 각 기준에 제시된 상업시설 바닥진동 제한범위에 만족하는 것으로 나타나 사용성이 우수한 것으로 나타났으나, 최대가속도 응답은 와플형 슬래브가 더블티형 슬래브보다 낮게 발생하였다.
