Description¶

The article's discussion derives design recommendations from its subgroup and literature findings. For usability, it recommends features that "enhance ease of use and users' level of satisfaction (eg, step-by-step instructions, user-friendly interfaces)" so students spend time learning rather than wrestling with software. For skills, it suggests adding haptic technology for realistic hands-on experiences and warns that too much immersion can cause cognitive overload; for clinical reasoning it cites beneficial elements including training duration over 30 minutes, varied clinical scenarios, nonimmersive 2D environments, and postscenario feedback.

Design Implications¶

Context¶

Requirements¶

• Designers must balance immersion against cognitive load, since 3D digital environments can increase cognitive load as students get distracted by irrelevant stimuli

Constraints¶

• These design feature recommendations come from the authors' interpretation of subgroup findings and cited studies, not from directly tested design comparisons in this meta-analysis

Target Learners¶

• medical and nursing students in pre- and postregistration education

Target Learning Goals¶

• procedural skill acquisition
• clinical reasoning
• communication skills

Claims¶

• Haptic simulator trials more frequently show superior accuracy outcomes when force-feedback and structured guidance are included [+W]
• Haptic virtual reality simulation reduces procedural time for pulpotomy training compared with conventional simulators [+W]
• Several included studies found haptic VR training equivalent rather than superior to conventional dental training [~W]
• Immersive VR-haptic and ITS modalities are more often associated with objective psychomotor and cognitive gains, while generative AI platforms are more often associated with affective outcomes [~W]

Related Strategies¶

• Progressively integrate haptic simulators from basic skills to complex surgical tasks across the curriculum
• Prefer mixed reality with hand tracking over head-mounted-display controllers for gesture-simulation training
