Abstract

The purpose of the present study is to develop and validate an instrument to assess STEM career motivation. We developed 32 items for 7 constructs (i.e. education experience, career value, academic self-efficacy, career self-efficacy, career interest, parents' support, and career motivation) on STEM career motivation based on Social Cognitive Career Theory (SCCT; Lent et al.,1994). 767 first year high school students participated in this study. The items were validated by Messick's framework (1995). In this study, we examined the validity of items in four aspects (i.e. content, substantive, structural and generalizability of validity). Methodologically, we used Rasch analysis, Exploratory factor analysis, confirmative factor analysis based on structural equation modelling. We confirmed that our instrument with 32 items as valid and reliable for measuring the STEM career motivation. In addition, we tested the STEM career motivation model based on SCCT. Our model explained the data well, suggesting that external factors (education experience and parents' support) and cognitive factors (perception of value, self-efficacy and interest) were significantly related to STEM career motivation.

이공계 진로동기는 지속가능한 과학기술 인력의 양성에 있어 핵심적 역할을 하며, 과학학습동기에도 큰 영향을 미친다고 알려져 왔다. 이 연구의 목적은 학생들의 이공계 진로동기를 측정할 수 있는 검사 도구를 개발 및 타당화하는데 있다. 검사도구 개발의 첫 번째 절차로 사회인지진로이론(SCCT)에 기초하여 고등학생들의 이공계 진로동기의 7개의 구인인 교육, 직업가치, 이공계 교과 자아효능감, 이공계진로 자아효능감, 이공계 진로에 대한 흥미, 부모의지지, 이공계 진로 동기로 설정하였다. 각 구인들을 측정할 수 있는 예비문항의 개발 후 고등학교 1학년 학생 767명에게 투입하였다. 학생들의 응답 자료를 바탕으로 라쉬모델 분석, 탐색적 요인분석과 구조방정식 분석을 바탕으로 한 확인적 요인분석과 다중집단 요인분석을 수행하였다. 결과적으로 Messick(1995)이 제안한 6가지 측면의 타당도 중 내용 타당도, 실제적 타당도, 구조적 타당도, 일반화 타당도가 검증되었다. 또한 구조방정식 분석을 통해 이공계 진로동기의 구인간의 연결 구조를 확인하였다. 개발된 이공계 진로동기 검사도구는 고등학교 1학년 직업진로지도에 유용한 도구로 사용될 것으로 전망된다.
