Abstract

It arises that teachers' professional competence should be considered not only with a cognitive perspective but also with a situative perspective. In this study, we considered mathematics teacher noticing as situational professional competencies of a mathematics teacher, and explored how mathematics teachers noticing on children's development of reasoning about variability in a video club has changed with the situative perspective. Findings illustrate that the 'interpreting' component among the three components of noticing-attending, interpreting, and deciding how to respond-was critically decisive for the change of the participant teachers' noticing. We also discussed how the video club intervention(the framework of children's development of reasoning about variability) can support the development of teacher noticing as a professional competence. This study has implications on the design of a video club to improve mathematics teacher noticing.

수학 교사의 전문 역량을 인지적인 관점뿐만 아니라 상황적인 관점에서도 바라보아야 한다는 주장이 대두되고 있다. 본 연구에서는 수학 교사의 노티싱(주목하기) 능력을 상황적인 맥락의 수학 교사 전문 역량으로 고려하는 입장에서, 비디오 클럽에 참여한 수학 교사들의 통계적 변이 추론에 대한 노티싱 변화를 탐색하였다. 그 결과, 노티싱의 세 가지 요소인 주의 기울이기, 해석하기, 반응 결정하기 중에서 '해석하기' 요소가 교사의 노티싱 변화 과정에서 중요한 역할을 하였음을 관찰하였다. 주의 기울이기와 반응 결정하기 요소는 해석하기 요소의 영향을 받아 결정되는 모습을 보였다. 또한, 영상으로 제시된 학생 활동과 관련이 있는 통계적 변이 추론 발달 프레임은 교사들의 논의를 통계적 변이성에 머무르게 하고, 의사소통을 활발하게 만들어줌으로써 노티싱의 변화를 간접적으로 이끌어 냄을 알 수 있었다. 본 논문의 말미에 수학 교사의 노티싱을 개선하기 위한 비디오 클럽의 중재 방안 설계에 있어 고려해야 할 점들에 관하여 논의하였다.
