Comparative Study
Use of an Analytical Grading Rubric for Self-Assessment: A Pilot Study for a Periodontal Oral Competency Examination in Predoctoral Dental Education.
While educators agree that using self-assessment in education is valuable, a major challenge is the poor agreement often found between faculty assessment and student self-assessment. The aim of this study was to determine if use of a predefined grading rubric would improve reliability between faculty and dental student assessment on a periodontal oral competency examination. Faculty members used the grading rubric to assess students' performance on the exam. ⋯ Students in the upper quartile self-evaluated themselves more harshly than the faculty (p<0.0001), while the lower quartile students overestimated their performance (p=0.0445) compared to faculty evaluation. No significant improvement was found in assessment over time in the students who took the exam in the third and fourth years. This study found only limited support for the hypothesis that a grading rubric used by both faculty and students would increase correspondence between faculty and student assessment and points to a need to reexamine the rubric and instructional strategies to help students improve their ability to self-assess their work.

Randomized Controlled Trial Comparative Study
Videotaped Feedback Method to Enhance Learning in Preclinical Operative Dentistry: An Experimental Study.
The aim of this study was to investigate if a videotaped feedback method enhanced teaching and learning outcomes in a preclinical operative laboratory setting for novice learners. In 2013, 60 dental students at a dental school in India were randomly assigned to two groups: control (n=30) and experimental (n=30). The control group prepared a Class II tooth preparation for amalgam after receiving a video demonstration of the exercise. ⋯ The means of SS (13.65±2.43) and ES (14.75±1.97) of the experimental group were statistically higher than the means of SS (11.55±2.09) and ES (11.60±1.82) of the control group. Most students in the experimental group perceived that this technique enhanced their learning experience. Within the limits of this study, the videotaped feedback using both ideal and non-ideal examples enhanced the students' performance.

Can Clinical Scenario Videos Improve Dental Students' Perceptions of the Basic Sciences and Ability to Apply Content Knowledge?
Dental students often have difficulty understanding the importance of basic science classes, such as physiology, for their future careers. To help alleviate this problem, the aim of this study was to create and evaluate a series of video modules using simulated patients and custom-designed animations that showcase medical emergencies in the dental practice. First-year students in a dental physiology course formatively assessed their knowledge using embedded questions in each of the three videos; 108 to 114 of the total 120 first-year students answered the questions, for a 90-95% response rate. ⋯ The first-year students indicated a more positive perception of the physiology course and its importance for success on board examinations and their dental career than the fourth-year students. The students perceived that the most positive aspects of the modules were the clear applications of physiology to real-life dental situations, the interactive nature of the videos, and the improved student comprehension of course concepts. These results suggest that online modules may be used successfully to improve students' perceptions of the basic sciences and enhance their ability to apply basic science content to clinically important scenarios.

Comparison of Dental Students' Self-Directed, Faculty, and Software-Based Assessments of Dental Anatomy Wax-Ups: A Retrospective Study.
Little is known about self-directed and self-reflective assessment in preclinical dental curricula. The aim of this study was to evaluate a visual dental anatomy teaching tool to train dental students to self-assess their dental anatomy wax carving practical examinations. The students self-assessed two waxing practical examinations (tooth #8 and tooth #19) using high-quality digital images in an assessment tool incorporated into a digital testing program. ⋯ For tooth #8, the student self-assessments were significantly different from the faculty and software assessments at a 400 micrometer level of tolerance (p=0.036), whereas the faculty assessment was not significantly different from the software assessment at a 300 micrometer level of tolerance (p=0.69). The evaluation of tooth #19 resulted in no significant differences between faculty members (p=0.94) or students (p=0.21) and the software at a level of tolerance of 400 micrometers. This study indicates that students can learn to self-assess their work using self-reflection in conjunction with faculty guidance and that it may be possible to use software-based evaluation tools to assist in faculty calibration and as objective grading tools.

The Role of Organizational Context in the Creation and Sustainability of Dental Faculty Development Initiatives.
Dental faculty development programs exist for a variety of reasons: to improve teaching skills, develop and reinforce relationships among colleagues and mentors, foster career development, and support curricular initiatives and institutional priorities. These activities impact individual faculty members as well as the institutions in which they work. ⋯ Contextual factors include the existence of an Office of Professional Development established in 1999, an Academy of Distinguished Educators founded in 2010, and other programs for present and future educators that support the college's educational mission. Outcomes include a comparison study of one program, the creation of new courses, the sustainability and expansion of existing programs, participants' retention rate, and an increase in awards and other educational accomplishments such as publication of abstracts, oral presentations, and related activities by NYU faculty at national forums in dental education.
