Evaluation of tooth preparations - A comparative study between faculty members and pre-clinical students

Abstract

Calibration of both students and examiners remains to be an issue with the teaching concepts applied in this study.

Dental students' peer assessment: a prospective pilot study

“…In contrast, BDS 2 students only started to notice peer improvement at the fifth session, whilst during the first four encounters, scores dropped significantly. This difference might be explained by an initial calibration process (48) or the time needed to gain experience as evaluators (49) or even adjusting to the learning environment (50), before scores started to rise. This increase in ratings over time is in keeping with the earlier findings of Prescott-Clements et al (36) in postgraduate dental trainees assessed by staff members in eight similar items, and Davies et al (51) in foundation medical trainees' peer assessment.…”

Implementing a new curriculum for computer‐assisted restorations in prosthetic dentistry

“…9 Tooth preparation is a basic technique of dental treatment and, therefore, plays an essential role in dental education. 10 Learning the widely differing forms of tooth preparation places high demands on both students and faculty in terms of three-dimensional conceptualisation, precision, reproducibility, and evaluation. 11 Self-evaluation of tooth preparation is especially essential for dental professionals.…”

Effects of Evaluator's Fatigue and Level of Expertise on the Global and Analytical Evaluation of Preclinical Tooth Preparation

“…One critical factor is the validity and reliability of the rubric used. In the development of effective rubrics, an important factor is the use of clear criteria to rate students’ work, and direct observation of the performance being evaluated . Therefore, the rubric used was presented to evaluators and students and pre‐validated with adequate intra‐ and interrater agreements.…”

“…This observation is in agreement with earlier reports. 3,6,7,10,37 However, several factors could have influenced the current outcomes. One critical factor is the validity and reliability of the rubric used.…”

“…In the development of effective rubrics, an important factor is the use of clear criteria to rate students' work, and direct observation of the performance being evaluated. 37 Therefore, the rubric used was presented to evaluators and students and pre-validated with adequate intraand interrater agreements. Although it was not clear if global grading was superior to analytical grading in this study, it was interesting that all examiners (faculty members and junior demonstrators) scored higher grades with the analytical grading method.…”
