RESUMO
With the extensive amount of learning required in dental schools, educators are constantly seeking more efficient learning models. The aim of this retrospective study was to evaluate a fixed prosthodontics course after its curriculum transitioned from a traditional lecture format to an active learning structure over the course of five years. In this retrospective, mono-centered study completed in 2018 at a U.S. dental school, data from the school's fixed prosthodontics course exams, National Board Dental Examination Part II (NBDE II), and the operative portion of the Western Regional Examining Board (WREB) licensure exam were collected for 381 students from the inaugural Class of 2015 to the Class of 2019. Data were evaluated for two groups based on method of instruction: the Classes of 2015 and 2016 were taught in a traditional model, and the Classes of 2017-19 were taught in the modified learning model. The data showed a 30% reduction in time students spent in the classroom and simulation clinic as compared to the previous model. The modified learning model reduced time spent in lecture, length of the course, and number of projects needed, while student performance remained consistent. Students in the active learning classes were able to pass all assessments including practical examinations at the same rate as previous classes using traditional learning methods. Students' performance on standardized national exams (NBDE II and WREB licensure exams) remained consistent among the graduating classes, and scores were comparable to the national average. Although limited in scope, this study suggests that it is possible to reduce contact time in fixed prosthodontics and maintain performance by increasing student engagement through active learning techniques.
