초록

최근 사회에서 창의적 문제해결 역량을 갖춘 인재에 대한 요구가 증가하면서 문제중심학습은 교육현장에서 가장 보편적으로 활용되고 있는 새로운 교수법이다. 이러한 교수법 적용에 따른 학습 효과를 수업 현장에서 간편하고 정기적으로 측정할 수 있는 도구를 본 연구를 통해 개발하였다. 기존 문제중심학습 효과 측정 연구에 활용된 문항을 수집하고, 전문가 의견 수렴을 통해 도구 개발을 위한 22개 예비 문항을 구성하였다. 이 문항을 이용하여 문제중심학습을 적용한 교과목을 수강한 학생 124명을 대상으로 데이터를 수집하였다. 이후 Rasch 분석을 통해 타당도와 신뢰도를 검증하였다. 124명의 학생 중 11명이 부적합, 22개 예비 문항 중 1개 문항이 부적합 판정되어 제외하였다. 또한 본 도구 구성을 위한 최적 척도는 4점 척도로 확인되었으며, 대상자와 문항에 대한 분리 신뢰도는 우수한 수준으로 확인되었다. 본 연구를 통해 개발한 문제중심학습의 효과 측정도구가 교육 현장에서 학습효과 측정 및 교육의 질 관리를 위해 적극 활용되길 기대한다.

Problem-Based Learning is the most commonly used teaching method in the field of education as the demand for talented people with creative problem-solving abilities has increased in recent society. In this study, we developed a tool that can simply and regularly measure the learning effects of applying Problem-Based Learning on the classroom. Twenty-two preliminary items for the development were constructed by gathering expert opinions about items collected in existing research of Problem-Based Learning effects measurement. Using this preliminary items, data were collected from 124 students who took the subject-based study. And the validity and reliability were verified through Rash analysis. 11 of 124 students and 1 of 22 items were found to nonconforming and excluded. In addition, the optimal scale for the configuration of this tool was found to be a four-point scale, and the reliability of separation on the subject and the item was found to be excellent. We hope that the assessment tools of Problem-Based Learning effectiveness developed in this study will be actively used to measure learning effectiveness and manage the quality of education.
