Abstract

The rubric is designed for a pre-clinical Removable Partial Denture Prosthodontics course that consists of weekly lectures followed by laboratory sessions. The full rubric is presented in an appendix in the laboratory manual and relevant sections of the rubric are provided in the evaluation form at the end of each lab. The rubric consists of four sections: surveying, removable partial denture (RPD) design, RPD drawing and mouth preparations. Continual exposure to the rubric in laboratory sessions reinforces criteria required for clinically acceptable results and facilitates self-evaluation by students. This teaching and learning tool also serves to calibrate instructors and provides a framework for instructors to provide feedback to students.

Surveying and RPD design are introduced to the students in increasing order of difficulty using the Kennedy classification system: Class I, Class III, Class IV and Class II. The students are provided with undercut locations for the casts as well as a series of digital camera photographs of the surveyed casts from various angles to guide them in completing the surveying exercise. Once they have attempted to design the RPD, the a series of digital camera photographs of RPD designs are provided to the students so that they can check their work, review concepts, and make any necessary corrections. These laboratory exercises are designed to provide dental students with the skills to independently survey and design cast RPDs.

The rubric was first developed in 2005 and has been used since 2006 in a second year pre-clinical removable partial denture (RPD) prosthodontics course. The rubric was developed to provide students with a visual one-page summary of the course that focuses on design of cast RPD frameworks. The checklist format guides students through the exercises and reminds them of criteria that need to be met for clinically acceptable results. The checklist format also allows for efficient delivery of feedback by instructors on students' strengths and weaknesses. The space on the evaluation form for comments is to be used for specific details necessary for the students to make improvements. The rubric was revised based on feedback from the 2009 class with the addition of weighting of each section reflecting emphasis on RPD design, and summaries on clinically acceptable and clinically unacceptable results emphasized in the course over the past four years. The photographs of the surveys and cast RPD designs on partially edentulous diagnostic casts illustrate how the criteria in the rubric have been met. This educational material appeals to students who are visual learners as well as those who are independent learners. Use of these supplementary learning materials has potential to free up instructors time so that they can assist students with other concerns in the course.

Educational Objectives

  1. To be able to provide a series of examples of surveying and RPD designs through digital photographs of the casts from different angles.
  2. To be able to provide a comprehensive detailed checklist on RPD design criteria for students and instructors to use in the evaluation process.
  3. To be able to provide an advance organizer for students outlining the expectations of the types of 1 skills they are required to develop in the course.
