Background

Virtual simulations (VSs) are increasingly utilized to train nursing students for clinical practice, yet few tools to evaluate VS quality, and little research has examined specific design elements that impact user experience across different modalities. Comparative evidence between screen-based VS and headset virtual reality (VR) within the same VS scenario is especially limited.

Purpose

The primary goal of this study is to identify challenging/bothersome events in a VS, compare how these events manifest in screen-based versus headset VR, and examine their impact on electrodermal activity (EDA; physiological arousal), performance, usability, and cognitive load.

Methods

A mixed-methods approach was applied to analyze audio-video and EDA data from 20 third-year nursing students during a VS. Objective performance scores were generated by the OMS software, while self-reported data on usability and cognitive load were collected through post-simulation surveys.

Results

Six challenging/bothersome event categories were identified: software-related restrictions and bugs, confusion/lack of success, negative affect, technical errors, neglect of instruction, and other. Results revealed that encountering challenging/bothersome events significantly increased students’ EDA (an indicator of physiological arousal), possibly reflecting frustration/confusion. Furthermore, while no single challenging/bothersome event category predicted performance or usability relative to others, we found that software-related restrictions and bugs were particularly critical, significantly increasing extrinsic cognitive load compared to technical errors.

Conclusions

Our findings highlight specific VS elements that hinder students’ experience, directly pointing to areas for future improvements. We also provide valuable insights for educators and developers to enhance virtual learning environments in nursing education by addressing how to reduce cognitive load and improve performance and usability. Future research should develop VS-specific usability tools and replicate this study in diverse contexts to further refine virtual learning experiences.
