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.
