Summary
Computer-based training using narration with pictures and animation significantly improved higher-level learning in older workers for respirator safety. This multimedia approach may be more effective than text-only or text with images for occupational health and safety training.
Area of Science:
- Occupational Health and Safety
- Adult Learning Theory
- Multimedia Learning
Background:
- Computer-based training (CBT) is increasingly used for worker education.
- Optimal structuring of CBT for adult learners remains unclear.
- Presentation format significantly impacts learning outcomes.
Purpose of the Study:
- To evaluate the effectiveness of CBT for occupational health and safety training in older workers.
- To compare different computer-based presentation methods for adult learning.
Main Methods:
- Developed three versions of a computer-based respirator training module: text-only, text with images/animation, and narration with images/animation.
- Assessed learning using a multiple-choice test (rote learning) and a transfer test (higher-level learning).
- Participants included manufacturing workers.
Main Results:
- Workers receiving narration with pictures and animation scored significantly higher on the transfer test.
- No significant differences were observed between groups on the multiple-choice (rote learning) test.
- Multimedia presentation enhanced higher-order thinking skills.
Conclusions:
- Concurrent narration with pictures and animation is a more effective CBT method for respirator safety training than other tested formats.
- This multimedia approach shows promise for improving occupational safety training effectiveness in adult workers.
- Further research is needed to optimize conditions for effective CBT implementation.
