연구공동체 활동을 통한 한 경력교사의 전문성 신장 : 수학적 창의성 촉진을 위한 대푯값 과제의 변형과 실행을 중심으로 = Professional development of an experienced teacher through research community activities: focusing on task modification and implementation to facilitate mathematical creativity

다국어 초록 (Multilingual Abstract)

The purpose of this study is to show that research community activities can contribute to the professional development in respect of average concepts and mathematical creativity. In the community, activities were undertaken to transform the existing task into the task that contributes to the manifestation of creativity. In this process, researchers tried to connect the theory with the practice of the class, and the teacher acted as an active learner. The findings show that the teacher who had difficulty in teaching average could overcome difficulties, and also derived the way of task modification and strategies necessary for teaching average. The modified task induced improvements in students’ achievement levels, which led to change in teachers' perspective on the relationship between mathematical creativity and learning. Research community activities have been shown to have contributed to improvements with regard to both teaching the average and promoting mathematical creativity.

국문 초록 (Abstract)

본 연구에서는 연구공동체 활동이 개념 지도와 수학적 창의성에 관한 교사 전문성에 어떤 변화를 가져오는지 살펴본다. 연구 결과, 연구공동체 활동은 교사가 개념 지도와 수학적 창의성 촉진 모두에 의미 있는 개선을 시도하는 데 기여한 것으로 나타났다.
