초록

일반적으로 가상훈련시스템은 서적과 슬라이드, 비디오와 같은 전통적인 교수매체보다 효과적인 훈련매체로 논의되고 있다. 그러나 직업훈련에 있어 학습자의 특성, 특히 경력별 차이는 가상훈련에 대한 태도와 인식, 심지어 학습효과에 영향을 미치는 요인으로 고려될 수 있다. 이에 본 연구는 가상현실 기반 직업훈련, 즉 가상훈련에 높은 관심을 보이는 대표적인 분야인 자동차정비 분야를 대상으로 가상훈련시스템을 개발하고 그 유용성을 체계적으로 검증하고자 하였다. 이를 위해 본 연구에서는 HMD와 VR 컨트롤러, 가상훈련 콘텐츠로 구성된 자동차정비 가상훈련시스템을 구현하고, 자동차정비 직업훈련의 대표적인 두 주체인 훈련생과 숙련된 재직자를 대상으로 반응평가를 통해 경력별 반응의 차이를 확인하고자 하였다. 반응평가에는 자동차 관련 학과 재학 중인 20대의 훈련생 11명과 현직에서 10년 이상의 경력을 가진 40~50대의 숙련된 재직자 10명, 총 21명이 참여하였다. 분석 결과, 학습자들은 가상훈련시스템의 학습과정 및 결과, 훈련내용, 훈련매체에 대해 전반적으로 긍정적으로 인식하였다. 또한, 숙련된 재직자들은 훈련생들보다 대체로 가상훈련시스템에 대해 긍정적인 반응을 보였으며, 콘텐츠영역의 수준 적절성(Z=-2.497, p=0.024)과 정보 명확성(Z=-2.16, p=0.043)에서 경력별 유의미한 차이도 확인되었다. 이상의 연구결과를 토대로 자동차정비 가상훈련시스템의 효과적인 개발 및 운영을 위한 시사점을 논의하였다.

Abstract

In general, a virtual training system (VTS) is known as a more effective training medium than traditional instructional media such as papers, slides, and videos. However, on the vocational training situations, the trainee’s awareness, attitude, and even learning effect can differ from the characteristics of the trainees, in particular their careers. In this vein, this study aimed to develop a VTS for automobile maintenance, which is a representative field with broad interests in the vocational training using VR technology and then to verify the developed VTS’s educational usefulness through the trainee’s career-related reaction evaluation. For this purpose, we developed the automobile maintenance VTS, consisting of an HMD, two VR controllers, and a training content. After that, we conducted the Kirkpatrick’s reaction evaluation in order to closely understand the trainee’s awareness about the developed VTS, focused on three evaluation areas such as the training, media, and content. Eleven novices (college students who learn automobile maintenance without the previous job experiences) and ten skilled workers (mechanic mechanics who have had automobile maintenance for more than 10 years) participated in this evaluation. Results indicated that all trainees respond positively to the developed VTS, and skilled workers showed more positive responses than novices without only three-questions. The significant differences between novices and skilled workers also revealed in ‘training level of relevancy’ (Z=-2.497, p=0.024) and ‘clarity of information’ (Z=-2.16, p=0.043). Based on these results, we discussed the implications for the effective development and utilization of the automobile maintenance VTS.
