Abstract

In this study, we explored the mediating effect of grit in the relationship between elementary school science teachers' perceived personal pedagogical content knowledge (pPCK) and enacted pedagogical content knowledge (ePCK). Drawing on insights from a review of the literature, we developed a research hypothesis model that set pPCK, ePCK, and grit as latent variables. Pearson correlation was conducted to examine the interrelationships among the latent variables. Structural equation modeling (SEM) was then employed to analyze the model fit. Additionally, bootstrap analysis was performed to specifically investigate the mediating effect of grit in the relationship between pPCK and ePCK. The Pearson correlation analysis indicated statistically significant correlations among the measurement variables. Meanwhile, the SEM analysis revealed that the measurement model aligned with the research hypothesis model. Furthermore, the bootstrap analysis demonstrated that grit had a statistically significant mediating effect in the relationship between elementary school science teachers' perceived pPCK and ePCK. These findings quantitatively examine the importance and impact of grit in the teacher expertise domain, providing valuable insights for the development of teachers' expertise and teacher education research within elementary school science classes.

이 연구에서는 초등학교 과학 수업에서 교사가 인식하는 개인적 PCK(pPCK)와 실행된 PCK(ePCK) 사이의 관계에서 그릿의 매개효과를 확인하고자 하였다. 문헌분석 결과에 기초하여 pPCK, ePCK, 그릿을 잠재변수로 설정하여 연구 가설 모형을 설계하였다. 분석 방법은 잠재 변수를 구성하는 측정변수들 사이의 상호관련성을 살펴보기 위해 Pearson 적률상관분석을 실시했고, 모형의 적합도를 분석하기 위해 구조방정식 모형을 사용하였다. 또한, 그릿의 매개효과를 구체적으로 살펴보기 위해 부트스트랩핑(bootstrapping) 분석을 실행하였다. 연구 결과, 측정변수들은 통계적으로 유의한 상관을 보였다. 구조방정식 분석 결과, 측정 모형은 연구 가설 모형에 부합하였다. 또한, 부트스트랩핑 분석 결과, 초등학교 과학 수업에서 교사가 인식하는 pPCK와 ePCK 사이의 관계에서 그릿의 매개효과가 통계적으로 유의하였다. 교사 전문성 영역에서 그릿의 중요성과 그 효과를 정량적으로 살펴본 이 연구의 결과는 초등학교 과학 수업에서 교사의 전문성 계발 및 교사교육 연구를 위한 중요한 시사점을 제공할 것으로 기대된다.
