Video-Recorded Testing for Student Self-Assessment: A randomized crossover study.

Area of Science:

• Dental Hygiene Education
• Clinical Skills Assessment
• Self-Assessment Strategies

Background:

• Developing critical reasoning and self-assessment is crucial for dental hygiene graduates.
• Traditional direct observation testing is a common method for evaluating preclinical skills.

Purpose of the Study:

• To compare the effectiveness of video-recorded testing versus direct observation testing on dental hygiene students' self-assessment scores, accuracy, and retest performance.
• To determine student and faculty preferences for each testing modality.

Main Methods:

• A randomized crossover AB/BA design was employed with first-year dental hygiene students (n=33) and faculty (n=13).
• Evaluated student self-assessment scores, faculty scores, accuracy scores, and utilized student/faculty surveys.
• Data were analyzed using descriptive statistics and independent samples t-tests (p<0.05).

Main Results:

• Student self-assessment scores were slightly higher with video testing (93.64%) than direct observation (91.98%).
• Retest and accuracy scores were similar between modalities, with no statistically significant differences.
• 80% of students preferred video testing, while 100% of faculty preferred direct observation.

Conclusions:

• Students favored video testing for self-assessment, citing improved mistake identification and correction.
• Faculty recognized video's benefits for self-assessment but preferred direct observation for comprehensive skill evaluation.
• Further research with high-quality video equipment and longitudinal studies is recommended.
