This study explored the effects of virtual reality (VR) application on the process and outcome of skill learning. The participants consisted of 60 new employees in the customer network cable service division of a telecommunications company, and the study focused on the learning of optical-fibre fusion splicing skills. The skill-learning test results revealed the following: (a) the skill-learning effect associated with VR application was greater than that of conventional lecturing and demonstration approaches; (b) VR application had a considerable negative effect on the perception level of skill learning but a moderately positive effect on adaptation and origination levels; and (c) in the VR operation stage of learning, the behavioural transition from the cognitive phase to the associative phase was the most prominent.
