The purpose of this study was to provide useful information for teachers by analyzing mathematical communication emphasized through 'exploratory activity' and 'story corner' in elementary textbooks based on the revised curriculum. Two classrooms from the first grade and second grade respectively were observed and videotaped. Mathematical communication of each classroom was analyzed in terms of questioning, explaining, and the sources of mathematical ideas. The results showed that only one classroom focused on students' thinking processes and explored their ideas, whereas the other classrooms focused mainly on finding answer. Particularly, this tendency often appeared when implementing 'story corner' than 'exploratory activity'. The reason for this was inferred that teachers were not familiar with teaching mathematics in stories and that teachers' manual did not include concrete questions and students' expected responses. This paper included implications on how to promote mathematical communication specifically in lower grades in elementary school.

The purpose of this study was to provide useful information for teachers by analyzing various levels of teacher-student communication in elementary mathematics classes and students' mathematical thinking. This study explored mathematical communication of 3 classrooms with regard to questioning, explaining, and the source of mathematical ideas. This study then probed the characteristics of students' mathematical thinking in different standards of communication. The results showed that the higher levels of teacher-student mathematical communication were found with increased frequency of students' mathematical thinking and type. The classroom that had a higher level of Leacher-student mathematical communication was exhibited a higher level of students' mathematical thinking. This highlights the importance of mathematical communication in mathematics c1asses and the necessity of further developing skills of mathematical communication.

21세기 지식정보화 시대의 정보과학기술은 중요한 교육으로 발전하고 있으며, 최근 6T를 기반으로 융합 IT는 미래사회의 중요한 과학기술로 연구 발전 시켜나가고 있다. 최근 이러한 융합적 IT기술의 근원은 창의성 계발과 아이디어를 중요시하고 있으며, 창조적 인재육성을 지향하고 있다. 창조적 인재육성은 창의적 문제해결 학습에 의한 두뇌의 발달과 창의적 설계를 가능하게 하므로 새로운 학습방법 연구가 활발히 진행 되어야 할 필요가 있다. 본 논문에서는 RDS를 이용한 창의적 문제해결 학습방법에 대하여 설명하고, 융합 IT분야에서도 미래사회에 가장 많은 영향력을 가지고 있는 지능로봇 분야의 창의적 설계와 응용을 학습할 수 있는 방법에 대하여 소개한다. RDS는 지능로봇 시뮬레이션 프로그램을 서비스 컴포넌트 기반으로 창의적 설계에 대하여 3차원 가상공간에서 학습자가 직접 프로그램으로 제작 실험이 가능하도록 지원한다. 또한 수학적, 과학적 학습의 효과를 동시에 IT에 접목할 수 있는 종합교육학습 시스템으로 발전시켜 나갈 수 있다. 시각적 시뮬레이션 환경(VSE)은 학습자의 문제해결력을 위한 경험과 실험을 동시에 실시간 제공할 수 있는 것이 큰 장점이다.
