Description

A structured teaching framework that deconstructs tooth extraction into nine sequential stages of increasing procedural complexity. From Stage 2 to Stage 9, students must complete five targeted observations and five successful supervised hands-on performances at the current stage before progressing. The model is informed by deliberate practice, mastery-oriented learning, workplace-based assessment, and entrustment-based progression principles. Failed attempts are not counted towards the progression threshold.

Design Implications

Context

Requirements

• Progression requires five targeted observations and five successful supervised hands-on performances at the current stage before advancing to the next stage.
• Each clinical attempt is directly observed by the supervising instructor and recorded as either 'Pass' or 'Fail' according to predefined criteria.

Constraints

• The numerical threshold was used as a pragmatic minimum exposure benchmark for this pilot study rather than as a literature-validated competency cut-off.
• The model was developed and evaluated only for tooth extraction, and both the nine-stage framework and modified DOPS tool were procedure-specific.

Target Learners

• Fifth-year undergraduate dental students

Learning Goals

• Procedural competence in tooth extraction
• Safe progression through increasing case complexity

Claims

• Microskill Stepwise Progression Improves Tooth Extraction Competence [+M]
• Microskill Stepwise Progression Reduces Score Variability [+M]
