Abstract

Teachers are the primary agent of didactic transposition. In the process of transposing mathematical knowledge presented in mathematics curriculum and textbooks to mathematical knowledge for teaching in a classroom, teachers are significantly influenced by not only teachers' personal factors but also circumstances and constraints existing inside and outside of classrooms. Therefore, to understand teachers' didactic transposition, we need to analyze influence of institutional and socio-cultural factors on teachers' didactic transposition process. Identifying factors and constraints influencing teachers' didactic transposition provides important opportunities to have a deeper understanding of teachers' didactic transposition and develop their classroom practices. This study analyzed secondary mathematics teachers' perspectives on didactic transposition by exploring factors influencing their didactic transposition process using their reflective journal about their classroom practices. As a result, we identified the five factors influencing participating teachers' didactic transposition. We also found that different teachers had different extent of influence of five factors on their didactic transposition. Based on the results, we discussed ways to help mathematics teachers' didactic transposition.

교사는 교수학적 변환의 핵심적인 주체이다. 교사가 교육과정과 교과서에서 제시된 수학적 지식을 수업에서 가르칠 지식으로 변환하는 과정에는 교사의 개인적 요인들뿐만 아니라 교실 안팎의 환경과 제약들이 지대한 영향을 미치게 된다. 따라서 교사의 교수학적 변환을 이해하기 위해서는 제도적, 사회적 요인들이 교수학적 변환 과정에 어떠한 영향을 미치고 있는지를 광범위하게 파악하고 분석할 필요가 있다. 교사의 교수학적 변환 과정에 영향을 미치는 요인들과 제약들을 분석하고 확인하는 것은 교사의 교수학적 변환을 심도 깊게 이해하고 교사의 수업 실행을 향상시킬 수 있는 중요한 기회를 제공한다. 이에 본 연구는 중등수학교사들의 반성적 저널을 활용하여 교사들의 교수학적 변환에 영향을 미치는 요인을 탐색함으로써 그들의 교수학적 변환에 대한 인식을 분석하였다. 연구 결과, 교사들의 교수학적 변환에 영향을 미치는 다섯 가지 요인들을 확인하였으며, 다섯 가지 요인들이 교수학적 변환에 영향을 미치는 정도는 교사들마다 다르게 나타났다. 연구 결과를 바탕으로 교사들의 교수학적 변환에 도움을 줄 수 있는 방안들을 논의하였다.
