Abstract

The purpose of this study was to examine the Pedagogical Content Knowledge(PCK) of teachers and their educational practice in the category of plane figure, to make a comparative analysis of their PCK and educational practice, and to discuss the relationship between their PCK and the characteristics of their instruction. Instruction of four selected elementary school teachers was analyzed to find out their educational practice. In conclusion, the characteristics of the PCK and actual instruction of the teachers could be listed as below: First, as a result of comparing their PCK and educational practice on plane figure by applying selected analysis criteria, there was a close correlation between their PCK and actual instruction. Second, the teachers had various levels of PCK on different areas. Especially, there was a large disparity in mathematical content knowledge and knowledge of teaching methods. Third, the teachers who had plenty of PCK were more excellent in textbook reconstructing, and those who fell behind in terms of PCK were more reliant on textbooks as if the textbooks had been the Bible.

교사의 수업 실제에 대한 개선이 절실히 요구되고 있는 상황에서 수학과 교육 전문성 향상을 위하여 본 연구는 교사의 PCK(Pedagogical Content Knowledge)의 특징을 알아보고, 교사의 PCK를 구분한 후 분석 준거에 의거하여 교사의 수학 수업의 실제를 관찰 및 분석하였다. 이에 초등학교 3학년 평면도형 단원을 선정하여 네 명의 서로 다른 PCK를 갖춘 교사를 대상으로 교사의 PCK와 수업을 비교 분석하는 연구를 실시하였다. PCK 수준에 따라 교사의 수업은 다르게 전개되었으며, PCK가 풍부할 때와 PCK가 부족할 때의 수업은 큰 차이를 보였다.
