Learning retinoscopy: A journey through problem space.

Area of Science:

• Ophthalmology
• Optometry
• Medical Education

Background:

• Retinoscopy is a fundamental clinical skill in optometry and ophthalmology.
• Acquiring proficiency in retinoscopy is often challenging for students due to its complexity.
• The skill integrates procedural techniques with declarative knowledge.

Purpose of the Study:

• To compare the strategies employed by novices, third-year students, and experts during retinoscopy.
• To identify key learning stages that can inform and improve teaching practices for retinoscopy.
• To understand the cognitive processes underlying expert performance in retinoscopy.

Main Methods:

• A protocol-based approach was utilized to record verbalizations and cognitive strategies.
• Participants included novices, third-year optometry students, and expert retinoscopists.
• Data were analyzed using 'problem space' analysis to understand strategy differences.

Main Results:

• Significant differences in retinoscopy performance and strategy use were observed across skill levels.
• Experts demonstrated higher accuracy and employed distinct, goal-directed strategies.
• The presence of specific strategies was a significant predictor of retinoscopy accuracy.

Conclusions:

• Metacognitive strategies and a strong theoretical knowledge base are crucial for effective clinical skill acquisition.
• Understanding expert strategies provides a pedagogical framework for teaching retinoscopy.
• Targeted teaching interventions focusing on metacognition and foundational knowledge can enhance student learning outcomes.
