Teaching-learning: stereoscopic 3D versus Traditional methods in Mexico City

Area of Science:

• Medical Education
• Dental Education
• Orthodontics

Background:

• Stereoscopic 3D (three-dimensional) teaching methods are increasingly adopted in dental education.
• Assessing the effectiveness of novel teaching strategies is crucial for optimizing student learning outcomes.

Purpose of the Study:

• To evaluate if 4th-year dental students achieve better learning outcomes in orthodontics using stereoscopic 3D compared to traditional teaching methods.

Main Methods:

• Selected course topics on supernumerary teeth were taught using traditional slide projection and stereoscopic 3D digital video projection with polarized glasses.
• A 24-item exam, validated by orthodontic teaching experts, was administered to 218 dental students (9 groups).
• Data were analyzed using SPSS 20, comparing pretest and posttest scores between the two groups.

Main Results:

• Students in the stereoscopic 3D group showed a greater improvement in posttest scores compared to the traditional group.
• Statistical analysis (ANOVA, Bartlett's test) indicated a significant difference favoring the 3D method (F=5.60, Prob > 0.0000).
• The 3D method demonstrated a strong association with improved learning outcomes.

Conclusions:

• Stereoscopic 3D teaching significantly enhances student learning in orthodontics.
• The findings support the integration of 3D technology in dental education for improved effectiveness.
