Description¶

The review recommends future directions for dental education, including exploring integration of emerging technologies such as augmented reality to improve visual mnemonics, and developing standardized guidelines for creating and implementing these tools. It highlights telestration, where "an instructor or clinician draws over a visual (e.g., radiographs, anatomy images, surgical video) in real‐time using a stylus, mouse, or touch screen," as employable in future dental education, and describes the Leap Motion Controller as a low-cost, contact-free device tracking hand movements that has been validated in eLearning settings.

Design Implications¶

Context¶

Requirements¶

• Instructor access to the relevant technology (stylus, touch screen, or gesture-capture device)

Constraints¶

• The review states traditional multimedia methods have limitations, and most cited technology evidence concerns medical rather than dental education

Target Learners¶

• dental and medical students

Target Learning Goals¶

• three-dimensional visualization of anatomical structures and improved retention of complex information

Claims¶

• Anatomy Glove Learning System improved hand-anatomy knowledge in both groups, with 3D-group self-confidence increasing over time while 2D-group confidence declined [+W]
• Air Anatomy hand gestures raised recall and applied-knowledge post-test scores, with the largest benefit for students of low to moderate spatial ability [+W]
• Supplementing traditional teaching with the GRAVEN hand-gesture database was associated with significant improvement in student academic performance in neuroanatomy [+W]
• In a randomized controlled trial reported in this review, the Hand as Foot teaching method received significantly higher teaching-effectiveness ratings than traditional teaching in a Human Physiology course [+W]
• Young children collaboratively develop their own gestures to represent and explain challenging science concepts in a mixed-reality environment [+W]

Related Strategies¶

• Augmented Reality (AR) for Medical Education and Training
• Prefer mixed reality with hand tracking over head-mounted-display controllers for gesture-simulation training
• Advocate and popularize emerging teaching methods as routine dental teaching, while combining them with traditional models to offset cost and time weaknesses
