Abstract

The purpose of this study was to explore changes in elementary teachers' modeling pPCK (personal PCK) resulting from knowledge exchange within the realms of PCK described in the Refined Consensus Model (hereafter RCM). For this purpose, a professional learning community (hereafter PLC) was established for three elementary school teachers to facilitate knowledge exchange specifically focused on science modeling instructions. The study then analyzed the CoRe (content representations) written by the research participants twice to explore any changes in modeling pPCK (personal PCK). In addition, the discourse shared by the participants in the PLC and the data from the in-depth interviews were also analyzed using grounded theory research methods. The results of the study showed that there was no significant change in knowledge of the science curriculum in elementary teachers' modeling pPCK, but there were changes in orientations toward teaching science, knowledge of students' understanding in science, knowledge of instructional strategies and representations, and knowledge of assessment of science learning. Furthermore, the analysis of PLC discourse and in-depth interviews showed that modeling instructions reflection (ePCK; enacted PCK) and educational research-based modeling cPCK (collective PCK) influenced these changes in teachers' modeling pPCK. Accordingly, this study suggests recommendations for pedagogical approaches aimed at improving teachers' modeling PCK.

본 연구는 개선된 합의 모델(RCM)의 세 가지 PCK 영역 간 지식 교환을 통해 초등교사의 모델링 pPCK(개인적 PCK)가 어떻게 변화되는지 탐색하였다. 이를 위해 초등교사 3인을 대상으로 한 전문적 학습공동체(PLC)에서 과학 모델링 수업에 관한 지식 교환이 이루어지도록 촉진한 뒤, 연구참여자가 두 차례 작성한 CoRe(내용 표상)를 분석하여 모델링 pPCK 변화 양상을 탐색하였다. 또한 PLC에서 연구참여자들이 나눈 담화, 심층 면담 자료를 근거 이론적 연구 방법을 활용하여 분석하였다. 연구 결과, 지식 교환으로 인해 초등교사의 모델링 pPCK 중 교육과정 지식에 있어서는 두드러진 변화가 없었으나 과학 교수 지향, 학생 이해에 대한 지식, 과학 수업 전략 지식 및 과학 평가에 대한 지식에 변화가 있었다. 또한 PLC 담화 및 심층 면담 분석을 통해 교사들의 이러한 모델링 pPCK 변화에는 모델링 수업 사례 성찰(ePCKR)과 교육 연구 기반 모델링 cPCK(집단적 PCK)가 영향을 미쳤음을 알 수 있었다. 연구 결과를 바탕으로 본 연구에서는 효과적인 교사의 모델링 PCK 개발을 위한 교육적 방법에 대해 논의하였다.
