Abstract

This study aims at exploring the features of science teaching orientation (STO) and its relationships with other PCK (pedagogical content knowledge) components. To do this, based on the definition of STO by Friedrichsen, Driel, & Abell(2011) and PCK model by Magnusson, Krajcik, & Borko(1999), we observed one experienced elementary teacher's science lessons for 21 lesson hours (10 hours of 'Motion of Objects' and 11 hours of 'Light and Lens') and carried out qualitative analyses of the data obtained from lessons observation, teacher interviews, and CoRe (content representation) responses. We analyzed the teacher's three aspects of STO (i.e. beliefs about the goals and purpose of science teaching, beliefs about the nature of science, and beliefs about science teaching and learning) which can converge into an overall STO of 'inquiry'. And these aspects of STO appear to interact differently with four PCK components (i.e. curriculum knowledge, learner knowledge, instructional knowledge, and assessment knowledge) depending on the topic of the lesson. It is hoped that this in-depth understanding of the features of STO and its relationship with other PCK components would provide useful information on how to monitor and improve STO and PCK of elementary teachers.

이 연구는 초등 과학교과 전담을 맡고 있는 한 경력 교사의 과학교수지향(sceience teaching orientation)의 특징과 과학 교수지향이 다른 PCK 요소들과 어떤 관련이 맺고 있는지를 탐색한 사례연구이다. 이를 위해 Magnusson, Krajcik, & Borko(1999)의 PCK 모델을 적용하였으며, 특히 과학 교수지향과 관련하여 Friedrichsen, Driel, & Abell(2011)의 정의를 이용하였다. 과학수업에 전문성이 있다고 인정받는 한 명의 초등교사를 연구 참여자로 선정하고 그의 과학수업 21차시를 관찰하였다(물체의 운동 단원 10차시, 빛과 렌즈 단원 11차시). 교사 면담과 참여 교사의 PCK를 명시적으로 파악할 수 있는 CoRe(content representation) 응답지를 수집하여 함께 분석하였다. 먼저 사전 면담 자료를 통해 참여 교사의 과학 교수지향을 귀납적으로 분석하였다. Friedrichsen, Driel, & Abell(2011)이 제안한 과학 교수지향의 세 측면(과학 교수의 목적과 목표에 관한 신념, 과학의 본성에 관한 신념, 과학 교수학습에 관한 신념)을 가장 잘 표현할 수 있는 어구를 찾고, 이를 상위 범주로 분류하여 이에 이름을 붙이는 범주화 작업을 하였다. 과학 교수지향을 제외한 다른 PCK 요소들의 특징은 CoRe 응답지와 수업 관찰 자료를 Magnusson, Krajcik, & Borko 1999)의 PCK 모델에 따라 연역적으로 분석하였다. 연구 결과, 과학교수지향의 세 측면과 관련하여 그는 각각 '과학과 일상생활과의 관계와 과학 개념의 습득', '앎에 이르는 방법으로서의 과학', '학생 중심수업' 신념을 가지고 있었다. 이러한 세 측면은 다중적이고 복합적으로 얽혀 있었으나 '과학 탐구'라는 하나의 과학 교수지향으로 수렴됨을 확인할 수 있었다. 또한 교사가 다른 PCK 요소의 선정과 조직에 관련하여 의사결정을 내릴 때 더 주요하게 영향을 미치는 신념이 있음을 관찰할 수 있었다. 과학수업 전문성을 가지고 있다고 인정받는 초등교사의 과학 교수지향의 특징, 과학 교수지향과 다른 PCK 요소들과의 관련성을 탐색한 이 연구의 결과는 초등교사의 과학수업 실천을 이해하는데 있어 과학 교수지향의 역할과 의미에 시사점을 줄 수 있을 것이다.
