- 예비과학교사의 비유 사용 수업에 대한 PCK 분석
- 이 연구에서는 예비과학교사의 비유 사용 수업 설계를 PCK 측면에서 분석하였다. 서울특별시에 소재한 사범대학에서 교육 실습에 참여한 3명의 예비과학교사가 연구에 참여하였다. 과학교육에서의 비유에 대한 워크숍을 실시한 후 교육 실습에서 비유 사용 수업을 실행하도록 하였다. 교육 실습에 참관하며 예비교사들의 수업을 관찰하였고, 예비교사들이 교수학습 자료를 수집하였으며, 반구조화된 면담을 하였다. 연구 결과, 예비교사들은 수업에서 비중 있게 다루는 비유에서만 대응 관계와 비공유 속성을 다루었고, 이 과정이 교사중심적으로 이루어졌다. 예비교사들이 교육과정을 벗어나는 개념을 포함한 비유를 수업에서 적절히 다루지 못하는 경우가 있었다. 예비교사들은 비공유 속성이 학생들의 오개념과 관련이 크다고 생각하였으나
