Summary
Computer-aided learning (CAL) in orthodontics shows weak correlation between test scores and student perception. Male students preferred self-instruction, but CAL tutorials should supplement traditional lectures.
Area of Science:
- Orthodontics
- Dental Education
- Educational Technology
Background:
- Computer-aided learning (CAL) in orthodontics has demonstrated various outcomes.
- No prior studies have correlated objective and subjective measures of CAL effectiveness.
Purpose of the Study:
- To correlate objective and subjective outcomes of computer-aided learning (CAL) in orthodontics.
- To assess student perceptions of the orthodontic diagnosis electronic tutorial (ODET) and CAL.
Main Methods:
- Administered a written test on the ODET to 92 dental students for objective assessment.
- Used a 12-statement questionnaire to gather subjective student perceptions of the ODET and CAL.
Main Results:
- Women scored higher on lecture tests than men (72.46% vs. 67.08%), but no sex difference was found for ODET test scores (P=0.52).
- Male students showed a preference for self-instruction over female students (P=0.05).
- A weak positive correlation (r=0.243) was found between ODET test scores and self-reported time spent reviewing the tutorial.
Conclusions:
- No significant difference in ODET performance between male and female students, potentially due to male preference for self-instruction.
- Increased time spent on the ODET correlated with improved test performance.
- Students perceive CAL tutorials as supplementary to, not replacements for, traditional lectures.
