초록
이 연구의 목적은 협력부하를 측정하기 위한 구인을 도출하는 것이다. 이를 위하여 문헌 분석을 통해 7개 요인을 도출하였으며, 이를 바탕으로 협력부하 측정 설문을 개발하였다. 이 연구에 참여한 연구대상은 교직과정을 수강한 대학생 및 교육대학원 학생 총 147명이며, 온라인 협력학습을 진행한 후 협력부하 측정을 위한 설문에 응답하도록 하였다. 탐색적 요인분석을 거쳐 과제 부담, 정신적 노력, 과제난이도, 과정만족도, 결과만족도, 환경 용이성, 몰입으로 구성된 총 7개 요인의 26문항을 확정하였다. 7요인에 의해 설명된 총 분산은 77.41%였으며, 모형 적합도는 양호한 것으로 나타났다. 확인적 요인분석을 실시한 결과, 전반적으로 구조모형에 대한 적합도 지수는 양호한 것으로 나타났다. 카이제곱과 GFI 값은 수용기준에 부합되지 않는 것으로 나타났으나 IFI(.798)나 CFI(.915), TLI(.901), RMSEA(.08)의 경우 수용기준에 적합한 것으로 나타나 구조 모형은 적합한 것으로 평가할 수 있었다. 본 연구를 통해 개발된 협력부하 측정을 위한 구인과 설문은 인지 심리학적 측면에서 제안된 협력학습 설계원리나 전략의 효과를 확인하는 데 유용하게 활용될 수 있을 것이라고 본다.
Abstract
The purpose of this study was to identify the measurement constructs of collaboration load and validate the factor model derived from the exploratory study. In an effort to meet the purposes literature review was conducted to establish initial factors, and it turned out 7 factors (physical efforts, mental efforts, task difficulty, self-evaluation of process, self-evaluation of outcome, learning environment design, flow). The total numbers of questionnaire items were 26, which each category contained 3-4 items. With the given initial factor model, an exploratory factor analysis was conducted. The extraction method was maximum likelihood method, and oblique technique was applied for the factor rotation. The total explained variance were estimated as 77.41%, and seven factor model was selected. Also an confirmative factor analysis was conducted to validate the seven factor model. The overall goodness-of-model fit was evaluated as acceptable: IFI, CFI, TLI, and RMSEA met with the minimum requirements. This study suggested that social-contextual feature should be added to measure collaboration load for the further study.
