Abstract

The purpose of this study is to develop and validate a tool that measures the satisfaction of virtual training learners' use of virtual training content. To this end, 491 copies of the basic questions derived from the satisfaction questions used by the K University Online Lifelong Education Center were used for the final analysis by conducting an online survey of learners who accessed STEP, the K University Online Lifelong Education Center portal. The 491 copies of data finally used were analyzed by methods such as basic question analysis, exploratory factor analysis, reliability analysis, and confirmatory factor analysis. First, in the basic question analysis, there were no questions that exceeded the acceptance criteria of an average of 4 points or more, skewness ±2, and kurtosis ±4. Second, the correlation coefficient for each sub-factor of virtual training content satisfaction derived after exploratory factor analysis was good as r=.682 to .822 (p<.01). The reliability coefficient for each sub-factor is content .849, content utilization .922, System and Operations Support .841, Intention to Continue Utilization .920, the overall reliability is. It was very high at .956 Fifth, as a result of confirmatory factor analysis, the compositional conceptual diagram is. It was .842 to .926, higher than the recommended standard of .7, and the average variance extraction degree. It appears to be .640 to .796, higher than the recommended standard of .5, which can be seen as representative of each constituent concept. As a result of verifying the validity of virtual training learners' content satisfaction recruitment, four factor models were derived: content substance, content utilization, system and operation support, and intention to continue use. This study is meaningful in that it empirically developed a tool to measure content satisfaction of virtual training learners and provided a reference frame and criteria.

본 연구는 가상훈련 학습자의 가상훈련 콘텐츠 활용 만족도를 측정하는 도구 개발 및 타당화하는 것이 목적이다. 이를 위해 K대학교 온라인평생교육원에서 2011년부터 2022년까지 가상훈련 만족도로 활용한 문항을 토대로 기초문항을 도출하였다. 이후, K대학교 온라인평생교육원 포털 STEP에 접근한 학습자를 대상으로 온라인 설문조사를 실시하여 성실하게 응답한 총 491부를 최종분석에 사용하였다. 최종 사용한 491부의 자료는 기초문항분석, 탐색적 요인분석, 신뢰도 분석, 확인적 요인분석 등의 방법으로 분석하였다. 첫째, 기초문항분석에서 평균 4점이상, 왜도 ±2, 첨도 ±4이상의 수용기준을 벗어난 문항은 없었다. 둘째, 탐색적 요인분석 실시 후 도출된 가상훈련 콘텐츠 만족도 하위요인별 상관계수는 r=.682 ~ .822(p<.01)로 나타나 양호하였다. 하위요인별 신뢰도 계수는 콘텐츠 내용 .849, 콘텐츠 활용 .922, 시스템 및 운영지원 .841, 활용지속의향 .920, 전체신뢰도는 .956로 매우 높게 나타났다. 셋째, 확인적 요인분석 결과, 구성개념도는 .842 ~ .926로 나타나 추천기준치인 .7보다 높았으며, 평균분산추출도 .640 ~ .796으로 나타나 추천기준치인 .5보다 높아 각각 구성개념에 대한 대표성을 갖고 있다고 볼 수 있다. 가상훈련 학습자의 콘텐츠 만족도 구인 타당성을 검증한 결과로 콘텐츠 내용, 콘텐츠 활용, 시스템 및 운영지원, 활용지속의향 등 4개 요인 모형이 도출되었다. 본 연구는 가상훈련 학습자의 콘텐츠 만족도 측정도구를 실증적으로 개발하여 준거 틀과 기준을 제공했다는데 의의가 있다.
