The Benefits and Challenges of Collaborative Learning: Educating Dental and Dental Hygiene Students Together.

Most often, members of the dental team are educated in separate programs. These professionals then come together in practice to work as a team, often with limited knowledge about each other's roles. The aim of this study was to assess the perspectives of dental and dental hygiene students regarding collaborative learning after taking two courses together. Five years (2010-14) of survey data were collected from a convenience sample of dental and dental hygiene students. The dental hygiene students were in their first and second years (DH1 and DH2) at Eastern Washington University (EWU). The dental students were in the University of Washington (UW) Regional Initiative in Dental Education (RIDE) program, taking their first year of courses in Eastern Washington with EWU's dental hygiene and UW's medical students. Eight first-year dental (D1) students participate in the RIDE program each year, totaling 40 across the five years. Because the same D1 students take both courses, this target population was 80. The number of DH1 and DH2 students in these courses ranges from 32-36 each year, for a target population of 323 across the five years. A total of 193 survey responses were collected, for an overall response rate of 48%; the D1 response rate was 72%, and the DH response rate was 42%. In the results, students perceived that learning collaboratively helped them think positively about other dental professionals, benefitted their problem-solving skills, increased their understanding of clinical problems, helped them become better team members, improved trust and respect, and improved their understanding of course content. These results suggest that collaborative learning had a positive impact on both groups. In comments, students suggested they would benefit from more shared learning experiences in the clinic and agreed that collaborative learning would help them create a more cohesive team.
