Summary
Computer-assisted instruction (CAI) and traditional lectures resulted in similar learning outcomes for dental students. However, students showed a clear preference for interactive CAI over lectures for learning intraoral radiography.
Area of Science:
- Dental Education
- Medical Informatics
Background:
- Traditional lecture formats are common in dental education.
- Advancements in computer-assisted instruction (CAI) offer new pedagogical approaches.
Purpose of the Study:
- To compare the effectiveness of CAI versus lecture-based instruction in dental radiology.
- To assess student learning preferences between CAI and lecture formats.
Main Methods:
- Seventy-five dental students were randomized into three groups: CAI only, CAI with lecture, or lecture only.
- Instruction focused on intraoral radiography.
- Pre- and post-tests evaluated learning; surveys assessed preferences.
Main Results:
- No significant differences in learning outcomes were found between CAI and lecture groups.
- Students overwhelmingly preferred the CAI format for learning.
Conclusions:
- CAI is an effective alternative to lectures for teaching intraoral radiography.
- Student preference strongly favors CAI, suggesting its potential for enhanced engagement in dental education.
