Abstract

In this study, we analyzed science teachers' NOS-PCK in Science Inquiry Experiment lessons. Four science teachers in charge of Science Inquiry Experiment in high schools located in the Seoul metropolitan area participated in the study. NOS Lessons were observed, all of the teaching-learning materials were collected, and semi-structured interviews were conducted. All the collected data were analyzed according to five factors of NOS-PCK. As a result of the study, their understanding and consideration of the curriculum related to NOS were insufficient in some cases. They thought that given inquiry activities or textbook composition was not effective for NOS teaching so that they actively reconstructed the curriculum. In terms of teaching strategies, their lessons were close to explicit approaches. However reflective approaches were generally lacking. They were neglected in evaluating NOS for reasons that views of NOS are individually subjective or that NOS is not an area of cognitive learning. They guessed the state of students by relying on their own experiences rather than based on evaluation results. They recognized a specific aspect of values of NOS learning. And intention to teach NOS played an important role throughout their classes. Based on the above results, we discuss some ways to improve the professionalism of science teachers for NOS teaching.

이 연구에서는 과학탐구실험 수업에서 나타나는 과학교사의 NOS-PCK를 분석하였다. 수도권에 소재한 고등학교에서 과학탐구실험을 담당하고 있는 4명의 과학교사가 연구에 참여하였다. 이들의 NOS 수업을 관찰하였고, 교수학습 자료를 수집하였으며, 반구조화된 면담을 실시하였다. 수집한 자료를 NOS-PCK의 다섯 가지 요소에 따라 분석하였다. 연구 결과, NOS와 관련된 교육과정에 대한 이해와 고려가 부족한 경우가 있었다. 그리고 주어진 탐구 활동이나 교과서의 구성이 NOS 교수에 효과적이지 않다고 생각하여 교육과정을 적극적으로 재구성하였다. 교수전략의 측면에서 교사들의 수업은 명시적인 접근에 가까웠으나 반성적인 접근은 대체적으로 부족하였다. 교사들은 NOS에 대한 견해가 개인의 주관적인 것이라거나 NOS가 인지적 학습의 영역이 아니라는 등의 이유를 들어 NOS에 대한 평가에 소홀한 모습을 보였다. 교사들은 평가 결과에 기반하기보다는 자신의 경험에 의존하여 학생들의 상태를 추측하였다. 마지막으로 NOS 교수에 대한 의지는 교사의 수업 전반에서 중요한 역할을 하였으며 교사들은 NOS 학습의 가치 중 특정 측면에 주목하였다. 이상의 결과를 바탕으로 NOS 교수에 대한 과학교사의 전문성을 높이기 위한 방안을 논의하였다.
