본 연구의 목적은 예비유아교사의 자아탄력성, 전공만족도, 직무수행효능감이 진로성숙도에 미치는 영향력을 알아보는 것이다. 이를 위해 서울과 경기도 지역의 3년제 유아교육과 재학생 319명을 대상으로 설문조사를 실시하여 수집한 결과를 분석하였다. 연구 결과는 다음과 같다. 첫째, 예비유아교사의 학년에 따라 자아탄력성, 전공만족도, 직무수행효능감, 진로성숙도에 차이가 있었으며, 특히 1,2학년과 3학년 사이에 통계적으로 유의한 차이가 나타났다. 둘째, 자아탄력성, 전공만족도, 직무수행효능감, 진로성숙도 사이에 통계적으로 유의한 상관관계가 나타났다. 셋째, 자아탄력성과 전공만족도, 직무수행효능감이 예비유아교사의 진로성숙도에 영향을 미치는 중요한 요인이었다. 이러한 결과는 예비유아교사들이 유아교사의 삶을 준비하고 직업세계로 안정적인 입문을 할 수 있도록 자아탄력성 및 전공만족도와 직무수행효능감 향상을 지원하는 교육프로그램의 필요성을 시사한다고 할 수 있다.The purpose of this study is to investigate the effects of ego-resilience, major satisfaction, and job performance efficacy of pre-service early childhood education teachers on their career maturity. To this end, a questionnaire survey was conducted on 319 students of the three-year college of early childhood education in Seoul and Gyeonggi Province, and the collected results were analyzed. The results of the study are as follows. First, there were differences in ego-resilience, major satisfaction, job performance efficacy, and career maturity according to the grades of pre-service early childhood education teachers, and in particular, there was a statistically significant difference between the first and second graders group and the third graders group. Second, it is found out that there are static correlations among the ego-resilience, major satisfaction, job performance efficacy, and career maturity of pre-service early childhood education teachers to each other. Third, it was found that ego-resilience, major satisfaction, and job performance efficacy were important factors affecting career maturity of pre-service early childhood education teachers. Among the variables, the effect of ego-resilience on career maturity was found to be the highest, followed by major satisfaction and job performance efficacy in order. These results imply the need for immediate previous education programs that supports the improvement of ego-resilience, major satisfaction, and job performance efficacy so that pre-service early childhood education teachers can prepare for the life of early childhood teachers and be provided with a stable entry into the professional world.
