Abstract

The goal of the study was to examine undergraduate students' perception of the importance of the concept of system in science. The participants are six undergraduate students in the department of science education. Data sources included interviews and interview notes. Results showed that students understood the concept of system as a group of objects, space, and boundaries, which differed from a previous research study about its details. The students also were able to explain the concept of system related with the process of problem solving. The students recognized as well the selection of system for analysis of natural phenomenon, explaining that the selection of system was determined by purpose of the observer. Lastly, the students explained that the concept of system was useful for science learning because it was strongly related with other science concepts, understanding of interactions, and learner's cognitive development.

본 연구의 목적은 대학생들의 시스템 개념에 대한 인식과 중요성을 탐색하여 과학 학습에 대한 시사점을 알아보는 것이다. 이를 위해 6명의 사범대학 학생들을 대상으로 심층 면담을 실시하였다. 면담에서 사용된 질문은 시스템에 대한 인식, 과학에서의 시스템 적용, 과학 학습에서의 시스템의 중요성으로 구성하였다. 분석은 면담 과정에서 사용한 주요 메모를 정리한 노트와 면담 과정을 녹음 후 전사한 자료를 토대로 진행되었다. 분석 결과, 첫째, 학생들은 시스템을 객체들의 집합, 공간, 경계 등으로 인식했으며, 선행연구와 다르게 면담 과정에서 구체적이며 다양한 설명을 확인할 수 있었다. 둘째, 학생들은 문제 인식과 계획 단계 등의 문제 해결 단계에서 시스템 개념이 관련된다고 설명했다. 이는 시스템을 선택할 때 요인을 추가하거나 제거하는 과정이 문제 해결 단계와 동일하다고 이해하고 있었기 때문이다. 셋째, 학생들은 자연 현상의 해석과 관련하여 시스템의 선택이 중요하다고 생각했다. 시스템은 관찰자의 목적에 따라 선택되고 주위와 구분된다. 넷째, 학생들은 다른 과학 개념 및 상호작용의 이해, 학생의 인지 발달 등과 같이 학습과 관련되어 시스템 개념이 유용하다고 설명했다. 본 연구결과에 따른 과학 교수-학습에서의 시사점을 논의하였다.
