In this article, we explored the value of interculturalism in developing the discourses of international cooperation in science education. By doing so, we interviewed four teachers who had an experience in teaching science in developing countries, and analyzed their experiences and perceptions in the lens of interculturalism and dialogue. Our analysis of teacher narratives shows the transition in the teachers' perspectives from volunteering and transmission to collaboration and learning. The transition from volunteering to collaboration occurred as the teachers learned how to meet 'the others' as themselves being strangers in the foreign context. Through intervening and colliding, teachers were able to reposition their identities as teachers. Furthermore, their science teaching practices show how the teachers tried to negotiate between the universal or idealistic value of science education and the heterogeneities formed by the country's cultural and specific situation of science education. Through these experiences, the teachers began to understand the importance of the culturally specific 'need' for science education. In conclusion, we proposed a discourse of science education collaboration based on interculturalism in terms of the diversity and complexity of science education practices in developing countries, teacher professionalism, culturally relevant pedagogy and sustainable policy.

본 논문에서는 멀티플랫폼 환경에서 헙력학습을 지원하는 e-Learning 시스템을 소개한다. 현재 IT 기술이 발전하면서 학습을 할 수 있는 단말의 종류는 과거에 비해 다양하다. 이러한 다양한 단말로 학습콘텐츠를 상호운용 시키기 위해서는 콘텐츠의 적응화가 필요하다. 본 연구에서는 적응화 방법을 소개하며 적응화를 위한 시스템의 architecture를 소개한다. 본 논문에서는 두 가지 적응화 방법을 고려한다. 학습콘텐츠 레이아웃 적응화와 학습자원의 적응화가 고려된다. 또한 학습효율을 향상하기 위해 협력학습을 지원하는 기술을 개발한다. 현재 ISO/IEC JTC1 SC36 WG2에서 헙력학습에 관한 기술표준을 추진 중이므로 본 논문에서는 SC36의 초안에 따라 기술을 개발하여 추후 국제표준을 선도할 것이다.

The aim of this paper is to develop a network-based collaborative learning system based on cooperative learning, computer simulation, role playing, and web-based instruction, which is called NetClass. It is an educational system of hybrid-type, and supports three learning modes as a distributed network, a stand-alone system, or a web browser. To accomplish the purpose of this paper, we have studied on the following topics. First, we selected appropriate learning contents among dilemmas on information ethics. Second, a Collaborative Dilemma-solving Learning Model (CDLM) was designed, and this model means systematic procedures that leaners can notice others' feeling and thinking and predict the results of his actions by introducing interactions among learners on computer networks. Third, Collaborative Learning System Model based on standard architecture of an educational system was proposed. Fourth, we developed many components such as network components, database components, and interface components.

The purpose of this study was to examine interactions among components of pedagogical content knowledge of middle school science teachers in a teacher learning community targeting science practice-based instruction. Data collection consisted of pre and post questionnaire and interview with each of five science teachers, audio-recording of teacher discussion in a teacher learning community, lesson plans, teacher written reflection, and video-recording of teaching practice. Qualitative data analysis revealed that there were two types of interactions, i.e., one-way interaction and two-ways interaction among components of pedagogical content knowledge of science teachers in a teacher learning community. There were also consecutive interactions as well as one-shot interaction. For two-ways interaction there were synchronous two-ways interaction in a teacher learning community meeting as well as consecutive two-ways interaction along with several meetings. This study provides implications that collaborative learning context in a teacher learning community should stimulate various types interactions among components of pedagogical content knowledge.

In recent creativity becomes a new request in the knowledge and information age. Robot programming education is an effective teaching method for improvement of creativity. Existing robot programming tools includes text-based or GUI-based development environment. Most of programming tools provide a simple tutorial system without interactive activity for beginners. In this paper, we propose an online robot programming education system based on web2.0, which embedded collaborative code creating tool, interactive tutorial chat and video conference tool to support collaborative code creating via web 2.0. Knowledge sharing tool allows users to share their collaborative source code. Besides, it makes users gained the experience and knowledge of program designing efficiently.

과학 문명의 발달은 산업 분야뿐만 아니라 사회, 문화의 영역에 이르기까지 폭발적 발전을 가능하게 하였으나, 자연 환경을 함부로 파괴하게 되었고 인류의 삶의 터전을 회복불능의 상태로 만들어 인간을 포함한 모든 생명체의 생존을 위협하고 있다. 환경은 한번 파괴되면 이를 회복시키는데 많은 시간과 비용이 소요된다. 따라서 환경에 대한 인식과 지식 및 기능을 습득하고 올바른 태도를 기르는 환경교육이 절실히 요구된다. 그러나 현재 우리 나라 초등학교에서의 환경교육은 대부분 인지적 측면만을 지고하고 있어 환경보전 인식의 내면화를 위한 교수-학습 방법을 필요로 하고 있다. 최근 웹을 교육에 활용하는 다양한 방법이 시도되고 있으며, 특히 웹 기반 프로젝트 학습은 정보의 수용이 아니라, 학생들의 연구에 의한 학습의 개념을 도입하고 있어 교사의 지도에 의지하지 않고 학생들의 자발적인 노력으로 프로젝트를 완성해 가는 것을 가능하게 해준다. 본 논문에서는 웹 기반 프로젝트를 활용하여 개인 또는 학급내 및 타 학급간의 협력을 전제로 환경을 탐구하고 환경 문제를 발견하며 이를 해결해 나가는 환경교육이 가능한 시스템을 설계하고 구현하였다. 이러한 웹 학습 공간을 마련하여 학습자가 다양한 자료를 쉽게 얻을 수 있게 함과 동시에 상호 정보 교환을 통한 협력 학습을 함으로써 이들에게 자연의 소중함을 일깨우고 환경보전을 실천하는 기틀을 다질 수 있도록 하였다.

There has been an amounting interest and subjects in gifted education in recent years as a number of studies dealt with the development of gifted education programs. However, earth science area remained as a low profile in developing educational programs and materials that meet the varying curiosities and needs of gifted students with a focus on their characteristic development. This study developed a small group-based active-cooperative learning program in middle school to investigate the effects of the program in terms of the creative problem solving ability in science and learning attitude of the gifted students. Then the study examined the conceptions of the students after the implementation of the small group-based active-cooperative learning program. Findings of the study showed that there was a significant increase in participated gifted students' creative problem solving skills and their learning attitude. In addition, the small group-based active-cooperative learning program apparently increased the participants' interests, satisfaction, and participation toward the instruction, and significantly influenced their affective domain. It implies that these findings were not caused by the lectures from the teachers, but by the variety of activities in which the gifted students discussed and debated with the classmates to derive a positive reciprocal action. In conclusion, a small group-based active-cooperative learning program promoted a reciprocal action among all the students who participated in a small group by sharing their opinions and respecting each other.

Wheatley(1991)에 의해 알려진 문제 중심 학습은 기계적 암기식 수학 학습을 대신해서 의미형성을 강조하기 위해 채택된 학습 방법 중의 하나로, 개인의 의미 구성을 도울 뿐만 아니라 의미있는 의사소동을 조장한다. 문제 중심 수업은 일반적으로 과제, 협력학습, 공유의 세 가지 요인의 상호작용으로 보여진다. 본 연구에서는 먼저 초등학교 5학년에 적용할 수 있는 문제 중심 수학 학습 프로그램을 개발하였으며, 개발된 프로그램을 학생들에게 적용함으로써 나타나는 수학 학습 상의 변화 및 아동의 수학에 대한 태도를 분석하였다.

The purpose of this study was to suggest strategies of team project based learning for undergraduate students by exploring the effects of perceived usefulness on satisfaction in team project-based learning. Also, this study investigated the effects of autonomy support, self-efficacy for group work, and perceived interaction on perceived usefulness. The findings of this study revealed that perceived usefulness affects satisfaction in team project-based learning. Moreover, the results showed that autonomy support and self-efficacy for group work influence perceived usefulness. The findings of this study imply that perceived usefulness is critical team project-based learning is critical to successful learning. Additionally, autonomy support and self-efficacy for group work enables users to perceive usefulness in team project-based learning.

다양한 실세계 응용 분야들에서 공동의 목표를 위해 여러 에이전트들이 상호 유기적으로 협력할 수 있는 행동 정책을 배우는 것은 매우 중요하다. 이러한 다중 에이전트 강화 학습(MARL) 환경에서 기존의 연구들은 대부분 중앙-집중형 훈련과 분산형 실행(CTDE) 방식을 사실상 표준 프레임워크로 채택해왔다. 하지만 이러한 다중 에이전트 강화 학습 방식은 훈련 시간 동안에는 경험하지 못한 새로운 환경 변화가 실전 상황에서 끊임없이 발생할 수 있는 동적 환경에서는 효과적으로 대처하기 어렵다. 이러한 동적 환경에 효과적으로 대응하기 위해, 본 논문에서는 새로운 다중 에이전트 강화 학습 체계인 C-COMA를 제안한다. C-COMA는 에이전트들의 훈련 시간과 실행 시간을 따로 나누지 않고, 처음부터 실전 상황을 가정하고 지속적으로 에이전트들의 협력적 행동 정책을 학습해나가는 지속 학습 모델이다. 본 논문에서는 대표적인 실시간 전략게임인 StarcraftII를 토대로 동적 미니게임을 구현하고 이 환경을 이용한 다양한 실험들을 수행함으로써, 제안 모델인 C-COMA의 효과와 우수성을 입증한다.
