Immersive virtual reality (IVR) offers possibilities of creating a learner-centric environment that can provide more presence and engagement for students leading to an enhanced learning experience compared to conventional classroom practices. However, the potential of IVR in vocational education and training (VET) has not yet been explored in-depth, and it is an open question of whether it can effectively support learner creation in a designing task. In this paper, we present an IVR application developed to support gardener apprentices in designing gardens. Using this application, we conducted an experimental study with gardener apprentices to investigate the effect of the IVR interface compared to paper sketching and learner behavior on the proportion, composition, and creativity of the design outcome. Additionally, we investigated how it can be combined with a paper sketching activity to improve its effectiveness. Our analysis shows that the IVR interface can be more effective for the proportion aspect, but this may be limited to students that are able to use it after working with paper. In terms of the combination order, the effectiveness of IVR on the design quality was improved when it was carried out after the paper sketching and this ordering produced a more effective outcome for the proportion and composition aspects. Finally, our results show that IVR design quality is related to learner behaviors such as the time spent on designing and the number of simulations used. This study demonstrates the effectiveness of IVR applications in supporting designing skills and how effectiveness can be improved by combining it with a conventional method of practice.

For the training of interpersonal skills, such as those required in the medical field, virtual agents can provide a safe environment for practice. However, many agent systems are not developed with the ability to understand non-verbal input. Being able to automatically parse such input is essential for the practice of interpersonal skills such as empathy. Currently, it is still an open question which prosodic or visual features would aid automatic classification of empathy and how this knowledge can be used to support the practice of these skills. As a first step towards this goal, we report on 42 second-year nursing students practicing their empathy skills with a virtual patient or through collaborative role playing. We found that across both the role playing and simulation, students assessed their empathy as increasing over time but as higher during the role playing. This work contributes to the continued development of virtual agents for the training of interpersonal skills.
