Reflections of psychomotor skill development in preclinical simulation: A qualitative analysis.

Introduction: Reflection on competency helps students become more proficient in performing skills, with the ultimate goal of better retention of knowledge and skill. Competency progression involves a complex interplay of factors, and not having the insight of such multiple perspectives of the same experience, we will not be able to understand students as learners fully and consequently may rely on assumption and may not be able to provide the necessary interventions for growth and progress towards competency. This study aims to investigate students' insight of their own progression during psychomotor skill development.
