Evaluating Student Self-Assessment through Video-Recorded Patient Simulations

Area of Science:

• Dental Hygiene Education
• Clinical Skills Assessment
• Educational Technology

Background:

• Accurate assessment of student performance is crucial in dental hygiene education.
• Traditional real-time feedback may be subject to biases.
• Video recording offers a potential tool for more objective evaluation.

Purpose of the Study:

• To evaluate the impact of video-recorded clinical sessions on the accuracy of dental hygiene student self-assessment.
• To determine if video recording influences the precision of dental hygiene instructor feedback.

Main Methods:

• A repeated measures experiment was conducted involving dental hygiene students and faculty.
• Participants were assessed on the ODU 11/12 explorer technique, first in real-time and then via video review.
• A standardized rubric was used for both initial and video-recorded reassessments, with faculty blinded to initial scores during reassessment.

Main Results:

• No significant differences were observed in overall student or faculty assessment scores between real-time and video-recorded evaluations.
• A significant difference (p=0.0001) was noted in the scores of specific grading criteria compared to expert assessment scores.
• Student self-assessment scores slightly increased when reviewed by video, while faculty scores slightly decreased.

Conclusions:

• Calibration and unbiased assessment in dental hygiene education remain challenging.
• Incorporating video analysis can potentially lead to more precise student performance and self-assessment.
• Further research is needed to refine assessment methods for improved educational outcomes.
