The purpose of this study is to suggest ways to diversify the teaching styles of pre-service elementary English teachers by investigating their teaching and learning styles. Specifically, this study intends to examine a) how the teaching styles of pre-service elementary English teachers change during their practicum and, b) how their learning styles are related to their teaching styles. Two teaching styles questionnaires (one before the practicum and another after the practicum) and a learning styles questionnaire were designed and distributed to a sample of 34 pre-service English teachers at a university in Korea who took their teaching practicum in their senior year. The analysis of the data revealed that before the practicum, the facilitator style, a learner-centered approach that views the teacher’s role as a facilitator of student learning, was the dominant, preferred teaching style. However, after the practicum, the subjects developed a more positive attitude toward the personal model style, a teacher-centered approach that views the teacher’s role as more of an authority in presenting information. The data also revealed that some of their learning styles were significantly related to their teaching styles. Those with individual, dependent and collaborative learning styles were found to prefer the facilitator teaching style, but those with group, independent and competitive learning styles tended to use the personal model style. These findings suggest that pre-service teachers try teaching in the styles they are reluctant to use in order to diversify their teaching styles in the classroom. Pedagogical implications for teacher education are also discussed.

This study examines the effects of a web-based testing program on children’s English learning. Specifically, it has two main aims: developing a web-based English testing program and investigating its effects on elementary English teaching. For this purpose, 37 children in the 4th grade participated in a 12-week experiment in which the subjects, after English class at school, performed tests every week at home using computers. The children were compared with a control group who took similar English classes but did not perform these tests. Data were obtained through tests, questionnaires and interviews focusing on the students’ achievements, interest in English, frequency of self-study at home, confidence in English, and motivation to learn English. The statistical analysis of the data did not yield clear conclusions. Interviews and personal contact with the children suggest, however, notable differences. The experimental group who took web-based tests tended to show a higher level of achievement as well as a more positive attitude toward English and English learning than did the control group. This hints at a potential usefulness of web-based testing programs in elementary English education.

BcN(Broadband Convergence Network) / NGN(Next Generation Network)은 통신 방송 인터넷이 융합된 품질 보장형 광대역서비스를 언제 어디서나 안전하게 즐길 수 있게 하는 차세대 통신망으로, 3GPP(3rd Generation Partnership Project)에서 표준화된 IMS(IP Multimedia Subsystem)를 기반기술로 채택하여 다양한 세션 기반 응용서비스를 개발하고 있다. 특히, IMS 기반의 통합 네트워크에서 제공하는 다양한 서비스 중에 OMA(Open Mobile Alliance)에서 발전되어지고 있는 PTT(Push-To-Talk) 서비스는 음성 및 텍스트 기반의 빠른 일대일 및 그룹 통신을 제공하는 서비스로 많은 이동통신 사업자들에게 중요한 서비스로 인식되고 있다. 하지만 음성 데이터 송수신에 제한된 기존의 PTT 서비스는 달리, IMS 기반 Multimedia PTT 서비스는 세션 중간에 다른 세션에 대한 추가와 변경이 용이한 IMS망의 특성으로 멀티미디어 데이터 송수신이 가능하다. 이에 본 논문에서는 멀티미디어 전송이 가능한 IMS기반의 Multimedia PTT 융합 서비스를 제안하고, 이를 바탕으로 구현한 테스트베드 시스템을 소개한다.

Different learning styles of children are known to play an important role in elementary English classrooms, yet little research has been conducted into developing survey questionnaires on the learning styles of EFL children. The purpose of this study was to develop a survey questionnaire on the learning styles of elementary EFL children. To achieve this outcome, the survey questionnaire was developed through the process of three stages. First, several existing survey questionnaires on learning styles were examined and preliminary survey questions were selected. Second, using the content validity test in which twenty EFL teachers were asked to assess whether the survey questions made sense to them, 63 questions were selected to write a new survey questionnaire. Third, the pilot survey questionnaire was administered to 413 elementary students, and using reliability analysis and factor analysis, a total of 36 items covering 8 categories of learning styles were designed to develop a final survey questionnaire on learning styles. Analysis of the data collected from the survey revealed that the questions in existing surveys touch on both the learning characteristics and the general characteristics of children, with some learning styles being integrated into the same category. It was also found that Korean EFL children are generally seen to show cooperative-competitive and audio-visual styles more clearly than other styles, perhaps in the elementary English classrooms in which much emphasis is placed on games, songs and group activities.
