Strengths:
- high ecological validity
- first longitudinal study
Limitations:
- sacrificed control for ecological validity
- exhaustion and boredom due to repeated testing
- small sample size

VR Simulation: Strengths and Limitations

- iVR works just as well as video presentation of the topic and yields better long-term results
- provides an interesting and novel alternative to typical lectures
- drop in perceived learning may be due to more difficult post-tests
- might need a more interactive iVR with more user agency to spark interest and enjoyment

Villanova University

- How does student interaction with multiple iVR simulations on different topics in environmental biology affect their (1) learning of the content related to those topics, (2) intrinsic motivation, (3) self-efficacy, and (4) perceived learning, and enjoyment over time? (Cross-sectional/longitudinal patterns)
- How does the effect of iVR simulations on the above-mentioned learning outcomes compare with video-viewing (where students watch videos of the respective simulations)? (Media comparison)

Long-term effectiveness of immersive VR simulations in undergraduate science learning: Lessons from a media-comparison study

- Improvements in knowledge for both conditions directly after
- Drop in knowledge for video group at 2 month follow up
- Gain in affective outcomes expected for both groups after first intervention, drop after second intervention 
- Novelty effect expected for iVR group


VR Simulation: Expectations/Hypotheses

- Higher knowledge gain immediately after intervention for iVR group
- Better long-term retention of knowledge by iVR group at 2 month follow-up
- Increase in knowledge performance for both groups

VR Simulation: Knowledge Results

- Intrinsic motivation: High for both groups over time throughout the study, no difference in groups with slight increase throughout
- Self-efficacy: High for both groups, slight increase throughout
- Perceived learning: High for both groups at first, decreased over time for both groups
- Enjoyment: higher for iVR group with video group reporting boredom
