Abstract

The purpose of this study is to construct two equivalent science relevance recognition test tool after confirming the reliability and validity of the CARS(Changes in Attitude of Relevance to Science) questionnaire to determine the applicability of the items to Korean students and to compare gender and school differences. For this study, 59 items of the CARS scientific relevance test were translated and assigned to 787 middle and high school students (analyed the answer of 300 middle school students and 431 high school students). In order to determine the fit of the CARS question to Korean students and to overcome the limitation of the number of questions, we used the item-linking method of the Rasch model. By analyzing the results of the research, we constructed two equivalent scientific relevance recognition questionnaires of CARS-A and CARS-B with 25 items. The Pearson correlation coefficient of the Rasch scores of the two equivalent test was 0.78. The two types of scientific relevance recognition test tools generated through this study can be used to confirm students' attitude of scientific relevance to daily life, or to confirm the change after a certain class or grade. Through this study, we will discuss the implications of students' perceptions of science associations in science education, and the development and application of tools.

이 연구의 목적은 CARS(Changes in Attitude of Relevance to Science)문항에 대한 신뢰도 및 타당도를 확인하여 우리나라 학생들에게의 적용여부를 판단하고, 성별 및 학교급별 차이를 비교한 후 라쉬 모델을 활용하여 두 개의 동형의 과학적 관련성 인식 검사도구를 구성하는 것이다. 이 연구를 위하여 59문항의 CARS 과학적 관련성 인식 검사문항을 번역하여 787명의 중 고등 (중학생 300명, 고등학생 431명의 답변이 분석됨) 학생들에게 투입하였다. CARS 문항의 우리나라 학생들에게의 적합도를 판단하고 많은 문항수의 제한점을 극복하기 위하여 라쉬 모델의 문항연결 방법을 활용하였다. 연구 결과를 분석하여 25문항으로 구성된 CARS-A와 CARS-B형의 두 과학적 관련성 인식 검사도구를 구성하였다. 두 동형검사도구의 라쉬 점수 상관관계는 0.78이며, 라쉬 모델 분석수치는 거의 일치하였다. 이 연구를 통해 생성된 두 형의 과학 관련성 인식 검사도구는 학생들의 과학의 일상관련 태도를 확인하거나, 특정 수업과정 후 또는 학년별 변화를 확인하는데 유용하게 활용될 수 있을 것이다. 이 연구를 통해 과학교육에서 학생들이 과학의 연관성 인식이 가지는 의미를 확인하고 도구개발 및 활용에 대하여 논의하고자 한다.
