Summary

For health professionals, computer-based continuing education is effective without animations. Plain versions of online learning materials are more likely to change clinical procedures than dynamic, animated versions.

Area of Science:

  • Medical Education
  • Orthodontics
  • Human-Computer Interaction

Background:

  • Continuing education for health professionals is increasingly delivered online.
  • The file size of multimedia elements, such as animations, can impact delivery speed.
  • The effectiveness of dynamic versus plain computer-based learning materials is not well understood.

Purpose of the Study:

  • To compare the effectiveness of dynamic (with animations) versus plain computer-based continuing education modules for orthodontists.
  • To assess the impact of multimedia elements on information retention and clinical behavior change.

Main Methods:

  • Orthodontists were randomly assigned to view a dynamic or plain computer-based education program on superelastic arch wires.
  • The program content was identical, differing only in the presence of transitions and animations.

  • Post-viewing questionnaires and follow-up surveys assessed user satisfaction and changes in clinical practice.

    • Main Results:

    • Over 90% of participants found both versions well-done and informative.
    • Some orthodontists found animations distracting; a few found the plain version unengaging.
    • The plain version led to a greater likelihood of changing clinical procedures compared to the dynamic version.

    Conclusions:

    • For highly motivated health professionals, animated elements in online continuing education may not be necessary.
    • Plain, non-animated computer-based learning materials can be equally or more effective in changing clinical behavior.
    • Optimizing online educational content for speed and effectiveness may involve omitting non-essential animations.
