Differences in learning retention when teaching a manual motor skill with a visual vs written instructional aide

Area of Science:

• Chiropractic Education
• Motor Skill Acquisition
• Learning Science

Background:

• Effective teaching methods are crucial for mastering complex manual motor skills.
• Evaluating learning retention aids in skill refinement and long-term recall.

Purpose of the Study:

• To compare the efficacy of visual teaching aids versus written guides for learning retention of a manual motor skill.
• To assess the impact of different review modalities on technique-specific recall in chiropractic students.

Main Methods:

• Seventy chiropractic students were randomized into two groups: one reviewing written guides, the other using visual teaching aids.
• Technique-specific recall was assessed before and after the review intervention.
• Repeated-measures analysis of variance was used to compare learning retention between groups.

Main Results:

• Both groups demonstrated significant improvement in performance post-intervention.
• The visual teaching aid group showed a statistically significant greater improvement (24.4%) in recall scores compared to the written guide group (17.7%).
• The difference in improvement between the visual aid and written guide groups was statistically significant (p = .03).

Conclusions:

• Visual teaching aids appear to be more effective than written guides for improving learning retention of manual motor skills.
• The findings suggest incorporating visual aids can enhance educational outcomes in chiropractic technique training.
• Further research could explore the long-term retention effects and applicability across different manual skills.
